FORMIC ACID

INDUSTRIAL - It has been used as a component of descaling and stain-removing agents, as a reducing agent in wool/textile dyeing, as a leather tanning, plumping and dehairing product for hides, as a catalyst in hydrocarbon-formaldehyde resins and phenolic resins, as a plasticizer for vinyl resins, and in coagulation of latex rubber and electroplating (Clayton & Clayton, 1994).

Descaling agents can contain formic acid concentrations of 44 to 60% (Moore et al, 1994). Industrial workers (e.g. airplane glue makers, cellulose formate and tanning workers) can be exposed to up to 60% solutions of formic acid (Clayton & Clayton, 1994).

AGRICULTURAL - It has also been used as an animal feed additive, food preservative, flavor enhancer, and brewing antiseptic (Clayton & Clayton, 1994). Formic acid has been used in Nordic countries as silage preservative. It also comes from fire ants.
THERAPEUTIC - Additional uses for formic acid have included: removal of tattoos, as a component in some external preparations in the treatment of musculoskeletal and joint disorders (Liesivuori & Savolainen, 1991; Chan et al, 1995) Ellenhorn, 1997; Reynolds, 1999). It also has the ability to prevent the growth of Candida albicans (Clayton & Clayton, 1994).
FOOD ADDITIVE - Formic acid has also been used as a food additive in small amounts (e.g., 0.1 to 6 ppm) in ice cream, ices, candy, and baked goods (Bingham et al, 2001).
OTHER - Formic acid has also been examined as the toxic metabolite produced in methanol poisoning. This management refers only to the direct effects of formic acid toxicity.

SOURCES

Formic acid is a natural constituent of some fruits, nuts, and dairy products (Clayton & Clayton, 1994). Some wines may contain formic acid. Concentrations in the following produce: apples, pears, plums, and apricots ranged from 2.7 to 87 mg/L.

-CLINICAL EFFECTS

GENERAL CLINICAL EFFECTS

Formic acid can be irritating or corrosive to the skin, eyes, and mucous membranes, depending on the concentration. It may cause severe caustic injury to the skin, eyes, or mucosal membranes.

Symptoms of acute ingestion (50 grams or more) can initially include salivation, bloody vomiting, a burning sensation in the mouth and pharynx, diarrhea, severe pain. Circulatory collapse and death have occurred following exposure.

In limited case reports, intentional oral ingestions of formic acid have resulted in life-threatening metabolic acidosis, profound hypotension, shock, ARDS, acute renal failure, and severe hemolysis. Systemic effects have also been reported following dermal exposure.

Occupational exposure has caused nausea and albumin or blood in the urine. Formic acid is a sensitizer for some individuals; allergic contact dermatitis or possibly asthma could develop in these individuals.

Combining formic and sulfuric acid produces carbon monoxide; severe carbon monoxide poisoning has resulted.

POTENTIAL HEALTH HAZARDS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 153 (ERG, 2004)

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death.
Contact with molten substance may cause severe burns to skin and eyes.
Avoid any skin contact.
Effects of contact or inhalation may be delayed.
Fire may produce irritating, corrosive and/or toxic gases.
Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

ACUTE CLINICAL EFFECTS

Formic acid is a STRONG ACID, and consequently is a CORROSIVE or irritant, depending on its concentration. Concentrated solutions can cause severe damage and ulceration of the skin, eyes, and mucous membranes (Clayton & Clayton, 1982).

The vapor was more potent as an irritant than was formaldehyde in guinea pigs (Clayton & Clayton, 1982). It is readily absorbed following inhalation (Clayton & Clayton, 1982), and direct contact with the eye can produce corneal opacity.

If ingested, formic acid can cause salivation, vomiting, a burning sensation in the GI tract, severe pain, and circulatory collapse.

CHRONIC CLINICAL EFFECTS

Occupational exposure to an airborne concentration of approximately 15 ppm of formic acid caused nausea, but apparently no other ill effects (ACGIH, 1986) except perhaps albumin or blood in the urine.

Formic acid is a SENSITIZER and some exposed persons may develop allergic contact dermatitis or occupational asthma.

-FIRST AID

FIRST AID AND PREHOSPITAL TREATMENT

DILUTION -

If no respiratory compromise is present, administer milk or water as soon as possible after ingestion. The exact ideal amount is unknown; no more than 8 ounces (240 mL) in adults and 4 ounces (120 mL) in children is recommended to minimize the risk of vomiting (Caravati, 2004).
USE OF DILUENTS IS CONTROVERSIAL: While experimental models have suggested that immediate dilution may lessen caustic injury (Homan et al, 1993; Homan et al, 1994; Homan et al, 1995), this has not been adequately studied in humans.
DILUENT TYPE: Use any readily available nontoxic, cool liquid. Both milk and water have been shown to be effective in experimental studies of caustic ingestion (Maull et al, 1985a; Rumack & Burrington, 1977; Homan et al, 1995; Homan et al, 1994; Homan et al, 1993).
ADVERSE EFFECTS: Potential adverse effects include vomiting and airway compromise (Caravati, 2004).
CONTRAINDICATIONS: Do NOT attempt dilution in patients with respiratory distress, altered mental status, severe abdominal pain, nausea or vomiting, or patients who are unable to swallow or protect their airway. Diluents should not be force fed to any patient who refuses to swallow (Rao & Hoffman, 2002).

EMESIS/NOT RECOMMENDED -

Do not induce vomiting.

ACTIVATED CHARCOAL

Activated charcoal is of no value, may induce vomiting and may obscure endoscopy findings. It is NOT recommended.

-MEDICAL TREATMENT

LIFE SUPPORT

Support respiratory and cardiovascular function.

SUMMARY

FIRST AID - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 153 (ERG, 2004)

Move victim to fresh air.
Call 911 or emergency medical service.
Give artificial respiration if victim is not breathing.
Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device.
Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes.
In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes.
For minor skin contact, avoid spreading material on unaffected skin.
Keep victim warm and quiet.
Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed.
Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.

FIRST AID

FIRST AID

EYE EXPOSURE - Immediately wash the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately. Contact lenses should not be worn when working with this chemical.
DERMAL EXPOSURE - Immediately flush the contaminated skin with water. If this chemical penetrates the clothing, immediately remove the clothing and flush the skin with water. Get medical attention promptly.
INHALATION EXPOSURE - Move the exposed person to fresh air at once. If breathing has stopped, perform artificial respiration. Keep the affected person warm and at rest. Get medical attention as soon as possible.
ORAL EXPOSURE - If this chemical has been swallowed, get medical attention immediately.
TARGET ORGANS - Eyes, skin, and respiratory system (National Institute for Occupational Safety and Health, 2007).

GENERAL -

Move victims of inhalation exposure from the toxic environment and administer 100% humidified supplemental oxygen with assisted ventilation as required. Exposed skin and eyes should be copiously flushed with water. Ingestion may result in significant esophageal or gastrointestinal tract irritation or burns, and EMESIS SHOULD NOT BE INDUCED. Cautious gastric lavage followed by administration of activated charcoal may be of benefit if the patient is seen soon after the exposure.

INHALATION EXPOSURE -

INHALATION: Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with an inhaled beta2-adrenergic agonist. Consider systemic corticosteroids in patients with significant bronchospasm.
If bronchospasm and wheezing occur, consider treatment with inhaled sympathomimetic agents.

DERMAL EXPOSURE -

DECONTAMINATION: Remove contaminated clothing and jewelry and place them in plastic bags. Wash exposed areas with soap and water for 10 to 15 minutes with gentle sponging to avoid skin breakdown. A physician may need to examine the area if irritation or pain persists (Burgess et al, 1999).
Treat dermal irritation or burns with standard topical therapy. Patients developing dermal hypersensitivity reactions may require treatment with systemic or topical corticosteroids or antihistamines.

EYE EXPOSURE -

DECONTAMINATION: Remove contact lenses and irrigate exposed eyes with copious amounts of room temperature 0.9% saline or water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist after 15 minutes of irrigation, the patient should be seen in a healthcare facility.

INGESTION EXPOSURE -

Do NOT induce emesis.
DILUTION: If no respiratory compromise is present, administer milk or water as soon as possible after ingestion. Dilution may only be helpful if performed in the first seconds to minutes after ingestion. The ideal amount is unknown; no more than 8 ounces (240 mL) in adults and 4 ounces (120 mL) in children is recommended to minimize the risk of vomiting.
Significant esophageal or gastrointestinal tract irritation or burns may occur following ingestion. The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation.
GASTRIC LAVAGE: Consider after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Protect airway by placement in the head down left lateral decubitus position or by endotracheal intubation. Control any seizures first.

CONTRAINDICATIONS: Loss of airway protective reflexes or decreased level of consciousness in unintubated patients; following ingestion of corrosives; hydrocarbons (high aspiration potential); patients at risk of hemorrhage or gastrointestinal perforation; and trivial or non-toxic ingestion.

Observe patients with ingestion carefully for the possible development of esophageal or gastrointestinal tract irritation or burns. If signs or symptoms of esophageal irritation or burns are present, consider endoscopy to determine the extent of injury.

-RANGE OF TOXICITY

MINIMUM LETHAL EXPOSURE

INGESTION

The lowest published lethal dose of formic acid for a woman via ingestion is 2,440 mcg/kg (RTECS , 2000).
Accidental or intentional overdoses (50 grams or more) are reported to produce salivation, vomiting (which may be bloody), a burning sensation in the mouth and pharynx, diarrhea, and severe pain. Circulatory collapse may follow, causing death (Clayton & Clayton, 1994).
CASE REPORT - A 56-year-old male died of cardiac arrest and multiple organ system failure 10 days after ingesting an unknown amount of a descaling agent which contained 55% formic acid, 1.6% phosphoric acid, and 4% quinoline (Jacques, 1982).
CASE REPORT - A 27-year-old male died approximately 26 hours after intentional ingestion of a decalcifying agent. The patient developed immediate vomiting and was transported to a hospital. Signs and symptoms of massive acidosis, excessive hemolysis, bleeding complications and eventually hepatic and renal failure occurred. It was estimated that the patient had ingested at least 30 to 60 grams (44 to 88 mL) of a solution containing 60% formic acid (Westphal et al, 2001).
CASE SERIES - Jefferys & Wiseman (1980) found that in a review of 45 patients who had ingested formic acid, painful deaths occurred in 14 of 16 patients who ingested between 45 to 200 grams of formic acid. The majority died from corrosive perforation of the abdominal viscera within the first 36 hours of exposure (Jefferys & Wiseman, 1980).
CASE SERIES - Three fatalities were reported following ingestion of household descaling agents which contained between 40% to 55% formic acid. One patient died of refractory hypotension, and postmortem exam revealed extensive erosion of the esophagus, stomach, and duodenum following a 50 to 100 mL ingestion of a kitchen descaling agent containing 55% formic acid (Naik et al, 1980).

DERMAL

CASE REPORT - A worker who had suffered splashes of hot formic acid to his face developed marked dyspnea with difficulty in swallowing and inability to speak; death occurred 6 hours later (ACGIH, 1991).

MAXIMUM TOLERATED EXPOSURE

INGESTION

CASE REPORT - A 36-year-old female ingested 110 grams of formic acid and developed acute renal failure, requiring intensive supportive care. Recovery was complete with the exception of intermittent dilation needed for persistent esophageal stricture (Moore et al, 1994).
CASE SERIES - In retrospective review of 45 cases of formic acid poisoning, 34 were found to be deliberate ingestions. Of those cases, 23 ingested between 5 and 30 grams of formic acid, and no deaths occurred. Serious toxicity was reported following ingestions between 30 to 45 grams (Jefferys & Wiseman, 1980).

INHALATION

The lowest published toxic concentration of formic acid for a man via inhalation is 7,300 mcg/m(3)/8 hours (RTECS , 1995).
Workers exposed to a mixture of formic and acetic acids at an average concentration of 15 ppm each complained of nausea (Hathaway et al, 1991).

OCULAR

CASE REPORT - transient opacification of the anterior half of the cornea was reported in a 30-year-old male following a one drop splash of concentrated formic acid in the eye (Sudarsky, 1965).

ANIMAL DATA

In studies of rats repeatedly exposed to oral doses (up to 360 mg/kg) of formic acid in drinking water, no adverse effects were reported with the exception of weight loss and decreased appetite. Likewise, Swiss mice exposed to formic acid (8% solution in water) painted on the ears did not develop any adverse effects (Clayton & Clayton, 1994).

GENERAL INFORMATION

This section provides a compilation of chemical resistance information and test data for specific protective clothing products. Chemical resistance information includes both degradation resistance ratings and permeation resistance data. This information is designed to assist in the selection of appropriate protective clothing. Only data on specific products and manufacturers are included. Generic information or recommendations are not provided since significant differences can exist in the chemical resistance for apparent similar product types.
Specific product information is organized by general product type (gloves, garments, and footwear), material type, and manufacturer. The category 'garments' may include totally encapsulating suits, splash suits, as well as other items (e.g., coveralls, jackets, and aprons). Specific manufacturers should be contacted to determine the features of available styles/models.
In addition to chemical resistance information, there are many critical variables in the selection of protective clothing which cannot be represented in this summary of the literature. Some factors to be considered in choosing protective clothing include, but are not limited to: overall clothing integrity, physical hazard resistance, durability, human factors, ease of decontamination, and cost. Overall clothing integrity refers to a specific design's ability to offer consistent protection for all clothing-covered areas of the body. Physical hazards include resisting the effects of abrasion, cuts, tears, and punctures. Human factors entail effects on wearer mobility, visibility, and hearing for garments; dexterity, tactility, and grip for gloves; ankle support and weight for footwear; and, any effect of the clothing on the function of the wearer. There are several variations in the design for gloves, garments, and footwear that affect these factors. Protective clothing must properly be sized and correctly fit the wearer to ensure its proper use and function.
As required in the U.S.A., protective clothing should be selected based on a risk assessment of the workplace. This risk assessment must account for the identification of existing as well as potential hazards and involve the recommendation of protective clothing appropriate for the identified hazards. Therefore, the recommendations in this section should not be used as the sole basis for decisions on choice of protective clothing, but rather should be used as a tool by qualified occupational health and safety professionals or other technically qualified persons in conjunction with a review of all mitigating factors. Consult the OSHA PPE Standard (29 CFR 1910.132 - 1910.138) for regulations and additional guidance regarding the selection and use of protective clothing and equipment. For general information on protective clothing selection, refer to the "PERSONAL PROTECTIVE EQUIPMENT - OSHA PUB 3077" document.
PROTECTIVE CLOTHING SELECTION

Determine the type of protective clothing item needed based on a risk assessment (e.g., gloves, garments, footwear).
For high risk situations, choose clothing that covers all parts of the body that may be exposed. In many cases, multiple clothing items will be required. Low risk situations may permit partial body protective clothing. Select protective clothing products that have reported chemical resistance data. High risk situations involving full body clothing or extended chemical contact often require permeation resistance data to determine the barrier effectiveness of materials used in the construction of clothing. Relatively low risk situations, where only splash or incidental exposure occur, may allow use of protective clothing based on degradation or penetration resistance data. Specifics on the interpretation of chemical resistance data are presented below.
Other factors must be considered in addition to chemical resistance. The selected chemical protective clothing item should offer the optimal combination of protection against identified hazards while allowing maximum function and comfort.

INTERPRETATION OF DEGRADATION RATINGS

Degradation refers to physical changes in a material as the result of chemical exposure. Degradation may become evident in visible changes, such as discoloration, swelling, delamination, deterioration, or disintegration. Degradation effects may also be measured by weight change or other changes in a material's physical properties (e.g., strength, elasticity, hardness).
Degradation resistance ratings are provided by manufacturers to rate the amount of degradation that occurs for a particular protective clothing material when contacted by a chemical. All degradation ratings are qualitative and include ratings, such as "EXCELLENT," "GOOD," "FAIR," "POOR," and "NOT RECOMMENDED." There is no standard test method for the measurement of chemical degradation resistance; therefore, manufacturer ratings may be based on different testing approaches. This makes comparison of degradation ratings between manufacturers unreliable.
The use of degradation resistance ratings alone to recommend protective clothing, particularly for high hazard situations, should be avoided. Degradation resistance testing does not directly assess the barrier quality of protective clothing, since materials can show relatively little degradation but still allow either permeation or penetration by a chemical. Degradation resistance ratings can be used to exclude protective clothing materials from consideration. Protective clothing materials with a "NOT RECOMMENDED" degradation resistance rating should never be used.
For some products, the rating "NO PENETRATION" is provided. This refers to penetration resistance test results that are based on a different procedure (American Society for Testing and Materials (ASTM) Standard Test Method F 903). Penetration resistance testing involves placing a material sample in a test cell, exposing the exterior side of the material to a chemical, and then observing the interior side of the material for visible signs of liquid penetration. Part of the test is conducted at an elevated pressure. Test results are reported as pass (no penetration) or fail (penetration detected). Unlike degradation testing, penetration testing provides an assessment of protective clothing material barrier performance. Since penetration resistance testing examines only observable amounts of liquid penetration, permeation may still occur. The use of penetration resistance data must be restricted to liquid chemicals, and should be limited to scenarios where there is no reasonable vapor exposure hazard under the conditions of exposure.

INTERPRETATION OF PERMEATION DATA

Permeation is the process of chemical movement through a material on a molecular level. Permeation resistance refers to the ability of a material to retard or prevent chemical movement through it. Permeation may occur without any visible signs of degradation.
Permeation resistance is measured using a test cell which is divided into two halves by a protective clothing specimen. Chemical is placed on the challenge side, while the collection side is periodically monitored for permeating chemical. Permeation data were obtained in accordance with the American Society for Testing and Materials (ASTM) Standard Test Method F 739 (Resistance of Materials Used in Protective Clothing to Permeation by Liquids and Gases), unless stated otherwise. In the case of chemicals that are classified as warfare agents, the data were obtained in accordance with the Military Standard 282 (MIL-STD-282) (Military Standard, Filter Units, Protective Clothing, Gas-Mask Components, and Related Products: Performance Test Methods).
Permeation rate is the amount of chemical that passes through a material for a measured surface area per unit time. In this section, permeation rate is expressed in micrograms per square centimeter per minute (mcg/cm(2)/min). The reported permeation rate is either the steady-state rate or the maximum rate observed during testing. In some cases, very large permeation rates exceed measurement techniques and are reported as ">" (greater than) or "HIGH."
Breakthrough time is the elapsed time, in minutes, from the time the chemical comes in contact with the material exterior surface, to the time that chemical is detected on the interior surface. When no breakthrough is detected, the breakthrough time is report as ">" the testing period. If permeation breakthrough is rapid, results are reported as "<" (less than) the earlier sampling time or as "IMMEDIATELY" (which usually means breakthrough in less than 4 minutes).
The breakthrough time should exceed the expected use period of the selected protective clothing. Additionally, there are several other factors that must be taken into account to provide appropriate protection.
Permeation testing is usually conducted with full strength, undiluted chemical for the duration of the test period. Actual exposures may involve diluted chemical for short or intermittent exposure periods.
Permeation testing is usually conducted at room temperature. Permeation occurs faster at elevated temperatures (short breakthrough times and higher permeation rates) and slower at reduced temperatures (long breakthrough times and lower permeation rates).
Permeation resistance of mixtures cannot usually be determined on the basis of the individual chemicals making up the mixture. Synergistic effects may occur and result in more rapid permeation than accounted for by the individual mixture chemicals.
Permeation rates may be used to calculate potential wearer exposure; however, several assumptions must be made about the extent of exposure and condition of clothing wear. Furthermore, there are few chemicals with dermal exposure limits, making it difficult to determine an acceptable skin exposure level.

- Substance may be transported in a molten form.
Formic acid is a flammable liquid when exposed to heat or flame. It can react vigorously with oxidizing materials (Lewis, 1992).

FLAMMABILITY CLASSIFICATION

NFPA Flammability Rating for CAS64-18-6 (NFPA, 2002):

Listed as: Formic Acid
Flammability Rating: 2

(2) Combustible. Materials that must be moderately heated before ignition can occur. Including liquids having a flash point above 100 degrees F, and solids that readily give off flammable vapors.

INITIATING OR CONTRIBUTING PROPERTIES

Formic acid is a flammable liquid when exposed to heat or flame. It can react vigorously with oxidizing materials (Lewis, 1992).

FIRE CONTROL/EXTINGUISHING AGENTS

SMALL FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 153 (ERG, 2004)

Dry chemical, CO2 or water spray.

LARGE FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 153 (ERG, 2004)

Dry chemical, CO2, alcohol-resistant foam or water spray.
Move containers from fire area if you can do it without risk.
Dike fire control water for later disposal; do not scatter the material.

TANK OR CAR/TRAILER LOAD FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 153 (ERG, 2004)

Fight fire from maximum distance or use unmanned hose holders or monitor nozzles.
Do not get water inside containers.
Cool containers with flooding quantities of water until well after fire is out.
Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.
ALWAYS stay away from tanks engulfed in fire.

NFPA Extinguishing Methods for CAS64-18-6 (NFPA, 2002):

Listed as: Formic Acid
Extinguishing Method(s): 5

5: Flammable liquid fires can be extinguished using carbon dioxide, dry chemical, foam, and vaporizing liquid extinguishers, as long as the fires are small to moderate in size and the flammable liquid reservoir is shallow. Use of foam to form a blanket over a flammable liquid is not effective when the liquid is water-soluble. Certain alcohol resistant foams are effective extinguishing agents for polar, non-polar, and water-soluble liquid fires. These foams are preferred for fighting flammable liquid fires except those that involve water reactive flammable liquids.

Use water spray, dry chemical, "alcohol resistant" foam, or carbon dioxide. Use water spray to keep fire-exposed containers cool (NFPA, 1991).

Use water in flooding quantities as fog. Solid streams of water may be ineffective. Apply water from as far a distance as possible. Use water spray to knock down vapors (AAR, 1992).

COMBUSTION TOXICITY

When heated to decomposition, formic acid emits acrid smoke and irritating fumes (Lewis, 1992).

EXPLOSION HAZARD

During preparation of peroxyformic acid by a patented procedure involving interaction of carboxylic acids with hydrogen peroxide in the presence of metaboric acid, an explosion may occur which can be attributed to spontaneous separation of concentrated peroxyformic acid (Bretherick, 1990).

Formic acid forms an explosive reaction with the following (Lewis, 1992; NFPA, 1991):

Furfuryl alcohol
Hydrogen peroxide + organic matter
Nitromethane
P2O5
Thallic nitrate trihydrate + vanillin

DUST/VAPOR HAZARD

Vapors are irritating and painful to breath. Vapor exposure may cause nausea and vomiting (CHRIS , 1995).

REACTIVITY HAZARD

Formic acid may react with alkalies and oxidizing materials such as peroxides, nitric acid, and chromic acid. Formic acid decomposes slowly during storage and more rapidly under fire conditions, forming carbon monoxide (NFPA, 1991).

Aluminum reduces formic acid (itself a reductant) with incandescence (Bretherick, 1990).

Formic acid is incompatible with concentrated sulfuric acid (NIOSH, 1995).

Formic acid is a flammable liquid when exposed to heat or flame. It can react vigorously with oxidizing materials (Lewis, 1992).

Formic acid is a strong reducing agent (Budavari, 1989).

During preparation of peroxyformic acid by a patented procedure involving interaction of carboxylic acids with hydrogen peroxide in the presence of metaboric acid, an explosion may occur which can be attributed to spontaneous separation of concentrated peroxyformic acid (Bretherick, 1990).

Formic acid forms an explosive reaction with the following (Lewis, 1992; NFPA, 1991):

Furfuryl alcohol
Hydrogen peroxide + organic matter
Nitromethane

CONTAINMENT/WASTE TREATMENT OPTIONS

SUMMARY

SPILL OR LEAK PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 153 (ERG, 2004)
- ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area).
- Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.
- Stop leak if you can do it without risk.
- Prevent entry into waterways, sewers, basements or confined areas.
- Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers.
- DO NOT GET WATER INSIDE CONTAINERS.
RECOMMENDED PROTECTIVE CLOTHING - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 153 (ERG, 2004)
- Wear positive pressure self-contained breathing apparatus (SCBA).
- Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection.
- Structural firefighters' protective clothing provides limited protection. fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible.
At the time of this review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices (HSDB , 1995).

LARGE LEAK/SPILL

Eliminate all ignition sources. Use water spray to cool and disperse vapors, protect personnel, and dilute spills to form nonflammable mixtures. Control runoff and isolate discharged material for proper disposal. Neutralize spill and washings with soda ash or lime. Report any release in excess of 5000 pounds (NFPA, 1991).
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary (AAR, 1992).
Land Spill: Dig a pit, pond, lagoon, or holding area to contain liquid or solid material (AAR, 1992).
Land Spill: Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete (AAR, 1992).
Land Spill: Absorb bulk liquid with fly ash or cement powder (AAR, 1992).
Land Spill: Neutralize with agricultural lime, crushed limestone, or sodium bicarbonate (AAR, 1992).
Water Spill: Neutralize with agricultural lime, crushed limestone, or sodium bicarbonate (AAR, 1992).
Water Spill: Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates (AAR, 1992).
Air Release: Apply water spray or mist to knock down vapors (AAR, 1992).
Air Release: Vapor knockdown water is corrosive or toxic and should be diked for containment (AAR, 1992).

WASTE TREATMENT OPTIONS

PHYSICAL TREATMENT

Formic acid is a good candidate for liquid injection incineration at a temperature range of 650 to 1600 degrees C and a residence time of 0.1 to 2 seconds (HSDB , 1995).
It is also a good candidate for rotary kiln incineration at a temperature range of 820 to 1600 degrees C and residence times of seconds for liquids and gases, and hours for solids (HSDB , 1995).
Formic acid is also a good candidate for fluidized bed incineration at a temperature range of 450 to 980 degrees C and residence times of seconds for liquids and gases, and longer for solids (HSDB , 1995).
Waste management activities associated with material disposition are unique to individual situations. Proper waste characterization and decisions regarding waste management should be coordinated with the appropriate local, state, or federal authorities to ensure compliance with all applicable rules and regulations.

-ENVIRONMENTAL HAZARD MANAGEMENT

POLLUTION HAZARD

Formic acid occurs naturally in plants and insects. It is also a product of microbial metabolism of organic matter and is produced in the photooxidation of biogenic and anthropogenic compounds. Formic acid will also be released to the environment as emissions and in wastewater in its production and various industrial uses (HSDB, 2004).

ENVIRONMENTAL FATE AND KINETICS

In the atmosphere, formic acid will be rapidly scavenged by rain and dissolve in cloud water and aerosols. It participates in reactions in clouds and aerosols involving dissolved hydroxyl radicals. The vapor phase acid also reacts with photochemically produced hydroxyl radicals (half-life 36 days) and possibly with alkenes that may be present in polluted urban air (HSDB, 2004).
In the atmosphere, formic acid reacts with photochemically produced hydroxyl radicals with a half-life of 36 days (HSDB, 2004).

WATER

SURFACE WATER
- Based on the results of screening studies, formic acid should biodegrade if released in water. It should not adsorb significantly to sediment. Bioconcentration in aquatic organisms is not expected to be an important fate process (HSDB, 2004).
- The Henry's Law Constant for formic acid is 1.67 x 10(-7) atm-m(3)/mole, indicating that volatilization from water would not be significant (HSDB, 2004).

SOIL

TERRESTRIAL
- If released on land, formic acid should leach into some soils where it would probably biodegrade based upon the results of screening studies (HSDB, 2004).
- Formic acid is miscible in water. Chemicals that are soluble in water do not usually adsorb significantly to soil or sediment due to hydrophobic forces. However, at ambient pHs, formic acid exists as the ion and may therefore have the potential to bind to clay or humic material by coulombic forces. However, no evidence of such binding has been reported (HSDB, 2004).

ABIOTIC DEGRADATION

Formic acid can be degraded chemically to innocuous substances in most environments. Screening studies indicate biodegradation is likely in water and soil. It will generally leach to subsurface soil and then biodegrade. Adsorption to aquatic sediment is not expected to be significant, nor is volatilization from water based on the Henry's Law Constant [1.67 x 10(-7) atm-m(3)/mole]. Airborne concentrations are dissolved in cloud water or aerosols present in the atmosphere where reactions can occur with dissolved hydroxyl radicals. The vapor (acid form) reacts with photochemically produced hydroxyl radicals and possibly with alkenes present in air pollution (HSDB, 2004).

BIODEGRADATION

Formic acid biodegrades readily in screening tests. It can be degraded biologically to innocuous substances in most environments (HSDB, 2004).

BIOACCUMULATION

BIOCONCENTRATION FACTOR

Formic acid has a log octanol/water partition coefficient of minus 0.54 from which a bioconcentration factor (BCF) of 0.22 can be estimated using a recommended regression equation. Therefore, formic acid should not bioconcentrate in aquatic organisms (HSDB, 2004).
