LIMONENE

Limonene is used in resin manufacturing, as a solvent or wetting agent, as a flavoring, and in the production of fragrance and perfume materials (Sun, 2007; Von Burg, 1995; Sax & Lewis, 1987). Limonene has been used as a stabilizer for aerosols (Bingham et al, 2001).
Limonene is on the GRAS (Generally Regarded as Safe) substances list of the Food and Drug Administration, and may be used as an additive in foods for human consumption (Sun, 2007; Hooser et al, 1986).
MEDICINAL

Limonene has been used medicinally in Japan as an agent to dissolve gallstones, for promoting wound healing, and in veterinary medicine as a component of an insecticidal dip (Von Burg, 1995; Bingham et al, 2001; Hooser et al, 1986; Igimi et al, 1991).
D-limonene has been used to dissolve cholesterol-containing gallstones, to relieve heartburn, and for chemopreventive activity against various types of cancers (eg, breast, colorectal) (Sun, 2007).

FORMS

Limonene is C10 cyclic olefin or terpene, optically active compound closely related to isoprene (Sax & Lewis, 1987; Bingham et al, 2001).

SOURCES

It occurs in both d- and l- forms, and is found naturally in fruits (lemons, oranges, mandarin, lime, and grapefruit), flowers, bark, and pulp from various trees and shrubs such as pine, anise, caraway, and polystachia. It is especially found in ethereal oils from bergamot, caraway, dill, lemons, and oranges (Sun, 2007; Von Burg, 1995; Budavari, 1996).
D-Limonene can be isolated from mandarin peel oil, or from lemon, orange, caraway, bergamot, peppermint, or spearmint oils (Von Burg, 1995; Budavari, 1996; Sax & Lewis, 1987). Limonene can be a component of cigarette smoke, and is found as a by-product in the manufacture of terpineol and in various products made from alpha-pinene or turpentine oil (Von Burg, 1995; Bingham et al, 2001; Gosselin et al, 1984). It may also occur in a racemic inactive or dipentene form, dl-limonene (Budavari, 1996; Sax & Lewis, 1987).
Other naturally occurring sources include human milk, saliva and fish (Von Burg, 1995).
Concentrations in various food items are as follow: Orange juice: 100 ppm; chewing gum: 2300 ppm; gelatin and puddings: 48 to 400 ppm; baked goods: 120 ppm; ice cream and ices: 68 ppm; candy: 49 ppm; non-alcoholic beverages: 31 ppm; soap and detergents: 0.05% to 0.75%; creams and lotions: 0.25%; perfumes: up to 2% (Sun, 2007; Von Burg, 1995).

-CLINICAL EFFECTS

GENERAL CLINICAL EFFECTS

USES: Limonene is a monoterpene and volatile hydrocarbon which occurs naturally in some trees and bushes. It is the predominant monoterpene in citrus oil and widely used as a flavor and fragrance additive for food and household cleaning products and solvents.

TOXICOLOGY: Limonene is C10 cyclic olefin or terpene. It has relatively low toxicity.

EPIDEMIOLOGY: Limonene is very commonly used in food and cleaning products, thus exposures are frequent. However, serious toxicity is rare.

WITH POISONING/EXPOSURE

MILD TO MODERATE TOXICITY: Mild to moderate toxicity typically consists of mild dermal irritation and skin sensitization. Ingestion of limonene may produce burning pain in the throat, abdominal pain, nausea, vomiting, and diarrhea.
SEVERE TOXICITY: Severe toxicity is typically due to large ingestion or aspiration. Severe toxicity is usually due to other ingredients in the product containing limonene. Aspiration can lead to pneumonitis and pulmonary edema. Large ingestions may produce hematuria, albuminuria, fever, dyspnea, tachycardia, and central nervous system effects including excitement, delirium, ataxia, and stupor.

POTENTIAL HEALTH HAZARDS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 128 (ERG, 2004)

Inhalation or contact with material may irritate or burn skin and eyes.
Fire may produce irritating, corrosive and/or toxic gases.
Vapors may cause dizziness or suffocation.
Runoff from fire control or dilution water may cause pollution.

CARDIOVASCULAR

Tachycardia may occur with limonene ingestion (Von Burg, 1995).

DERMATOLOGIC

Limonene is generally regarded to have low toxicity by the dermal exposure route (Von Burg, 1995). It can be absorbed through intact skin (Clayton & Clayton, 1994).
DERMATITIS: Limonene has a direct irritant effect and may cause sensitization (Von Burg, 1995).
Severe occupational contact dermatitis of the hands due to handling vegetables containing celeriac has been reported and may be due to limonene content (Agathos, 1980). Limonene may be responsible for occupational orange-handlers dermatitis, although some individuals with orange peel sensitivity do not react to lemon peel which also contains limonene. Old honing oils and paint thinners containing limonene have also been associated with an allergic contact dermatitis. This has become rarer as the manufacturers have removed limonene from these products (Mitchell, 1982).
Limonene may be absorbed through intact skin at 100 times the rate of water and 10,000 times the rate of sodium and chloride. It is, however, of low toxicity by the dermal route in experimental animals (Bingham et al, 2001).
Skin sensitization may occur (Von Burg, 1995; Gosselin et al, 1984; Budavari, 1996).

GASTROINTESTINAL

Burning pain in the mouth and throat, abdominal pain, nausea, vomiting and diarrhea may occur with limonene ingestion (Von Burg, 1995).
An odor of terpenes on the breath and in the vomitus may be noted following limonene ingestion (Von Burg, 1995).

GENITOURINARY

Albuminuria and hematuria might occur if large amounts of limonene are ingested (Von Burg, 1995; Gosselin et al, 1984). Oliguria has been reported in one case of ingestion of pine oil containing 6% limonene (Koppel et al, 1981), but was most likely due to the major component, alpha-pinene.

HEENT

Eye irritation or burns may be observed with direct eye contact with concentrated limonene (Von Burg, 1995).

NEUROLOGIC

Transient excitement, ataxia, delirium and stupor may occur with limonene ingestion (Von Burg, 1995).
Dizziness and suffocation may be observed following limonene inhalation (Von Burg, 1995).

RESPIRATORY

Pulmonary edema and pneumonitis may occur with limonene aspiration or systemic absorption (Von Burg, 1995).
Coughing, choking, dyspnea and cyanosis may occur following limonene ingestion (Von Burg, 1995).
In a human inhalational study, a statistically significant decrease in vital capacity was noted, especially at the higher dosage range (450 mg/m(3)) (Falk-Filipsson et al, 1993).
Although not reported, lipoid pneumonitis might occur if limonene is aspirated into the lungs (Falk-Filipsson et al, 1993).

VITAL SIGNS

FEVER: Fever may occur with limonene ingestion (Von Burg, 1995).
HYPOTHERMIA has been noted in animals with either dermal or oral exposure to limonene (Hooser et al, 1986; RTECS , 2002). This effect has not been reported in exposed humans.

CHRONIC CLINICAL EFFECTS

While a 20% limonene solution was not irritating or sensitizing in controlled human patch testing (HSDB; (Von Burg, 1995), it may be a weak sensitizer and could be responsible for rare allergic reactions (Clayton & Clayton, 1994) HSDB). Several cases of contact dermatitis have been reported involving honing oil (Rycroft, 1980) and paint thinner (Calnan, 1979) containing D-limonene. After the manufacturer removed the D-limonene from the honing oil, the allergic reactions disappeared.

Its role as an occupational skin sensitizer is of concern because limonene is also used in many household products and toiletries. Once an individual becomes sensitized to limonene, it may be difficult to avoid further exposure.

In experimental animal studies, limonene produced nausea, lower weight gain, lowered blood sugar and cholesterol, and some kidney damage in dogs exposed for 6 months (Tsuji, 1975b). Pure d-limonene was not sensitizing in a guinea pig patch test, but d-limonene oxide, the product of oxidation in air, was a potent allergen (Von Burg, 1995).

-FIRST AID

FIRST AID AND PREHOSPITAL TREATMENT

PREHOSPITAL: Remove clothing and wash exposed areas with soap and water. If ocular exposure develops, irrigate thoroughly. With inhalational exposures, move patient to fresh air. GI decontamination is not recommended after ingestion. Small amounts of water can be administered to decrease oral irritation.

-MEDICAL TREATMENT

LIFE SUPPORT

Support respiratory and cardiovascular function.

SUMMARY

FIRST AID - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 128 (ERG, 2004)

Move victim to fresh air.
Call 911 or emergency medical service.
Give artificial respiration if victim is not breathing.
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.

In case of burns, immediately cool affected skin for as long as possible with cold water. Do not remove clothing if adhering to skin.
Keep victim warm and quiet.
Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.

FIRST AID

SUMMARY

Remove clothing and wash exposed areas with soap and water. If ocular exposure develops, irrigate thoroughly. With inhalational exposures, move patient to fresh air. GI decontamination is not recommended after ingestion. Small amounts of water can be administered to decrease oral irritation.

ORAL EXPOSURE

GI decontamination is not recommended after ingestion. Small amounts of water can be administered to decrease oral irritation.

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.

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).

-RANGE OF TOXICITY

MINIMUM LETHAL EXPOSURE

One source reported a probable oral lethal dose of 0.5 to 5 grams/kilogram or between one ounce and one pint in a 70 kg human (Von Burg, 1995; Gosselin et al, 1976).

ANIMAL DATA

A daily dose of 1000 mg/kg caused maternal toxicity and some deaths in pregnant rabbits, while a daily dose of 250 mg/kg caused no effects (Bingham et al, 2001).

MAXIMUM TOLERATED EXPOSURE

DAILY PER CAPITA CONSUMPTION: In the United States, the daily per capita consumption of d-limonene from all sources (natural and flavorings) is about 0.27 mg/kg/day for a 60 kg individual (0.27 mg/kg body weight x 60 kg = 16.2 mg/person/day) (Sun, 2007).

In one study, increased bowel movements (2 to 3 times daily) and tenesmus developed in 5 healthy male volunteers after receiving a single dose of 20 g d-limonene. All laboratory results were normal (Sun, 2007).

An ingestion of 100 mg/kg of limonene (equivalent to about 7 g for an average man) resulted in mild eructation for 1 to 4 hours postingestion, mild satiety for 10 hours postingestion, and slight fatigue for 4 hours postingestion (Sun, 2007).

In a dose escalation study, when oral d-limonene doses 0.5 to 12 g/m(2)/day (1 to 24 g/day, considering an average area per person is 1.9 m(2)) were administered to 32 patients with refractory solid tumors for 21 days, nausea, vomiting, and diarrhea were observed. These adverse effects were dose-dependent, with the maximum tolerated oral dose of 8 g/m(2)/day (15 g/day). This dose was administered to a breast cancer patient for 11 months (Sun, 2007).

ANIMAL STUDIES

In an animal study from the National Toxicology Program (NTP), when mice and rats were administered d-limonene (greater than 99% pure) doses 413 to 6600 mg/kg daily 5 days per week for 3 weeks, no signs of compound-related toxicity were observed following doses less than 1,650 mg/kg/day (Sun, 2007).
MALE RATS: 600 mg/kg/day of limonene caused decreased weight gain and even death; 1200 to 2400 mg/kg/day caused rough hair coats, lethargy, excessive lacrimation, and nephropathy (Sun, 2007).
MICE: 1000 and 2000 mg/kg/day of limonene caused decreased body weight gain, lethargy, and rough hair coats (Sun, 2007).
A chronic daily dose of 1.2 to 3.6 mL/kg of limonene administered to dogs for 6 months produced some unspecified effects (Bingham et al, 2001).
Doses of 2363 to 2869 mg/kg daily for 6 to 7 days caused some teratogenic effects in mice (Bingham et al, 2001).
A daily dose of 1000 mg/kg caused maternal toxicity and some deaths in pregnant rabbits, while a daily dose of 250 mg/kg caused no effects (Bingham et al, 2001).

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.

-PHYSICAL HAZARDS

FIRE HAZARD

SUMMARY

POTENTIAL FIRE OR EXPLOSION HAZARDS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 128 (ERG, 2004)
- HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
- Vapors may form explosive mixtures with air.
- Vapors may travel to source of ignition and flash back.
- Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks).
- Vapor explosion hazard indoors, outdoors or in sewers.
- Those substances designated with a "P" may polymerize explosively when heated or involved in a fire.
- Runoff to sewer may create fire or explosion hazard.
- Containers may explode when heated.
- Many liquids are lighter than water.
- Substance may be transported hot.
- If molten aluminum is involved, refer to GUIDE 169.
Shut off all sources of ignition (Prod Info, 1985).

(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.

FIRE CONTROL/EXTINGUISHING AGENTS

FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 128 (ERG, 2004)

CAUTION: All these products have a very low flash point: Use of water spray when fighting fire may be inefficient.
CAUTION: For mixtures containing a high percentage of an alcohol or polar solvent, alcohol-resistant foam may be more effective.

SMALL FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 128 (ERG, 2004)

Dry chemical, CO2, water spray or regular foam.

LARGE FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 128 (ERG, 2004)

Water spray, fog or regular foam.
Use water spray or fog; do not use straight streams.
Move containers from fire area if you can do it without risk.

TANK OR CAR/TRAILER LOAD FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 128 (ERG, 2004)

Fight fire from maximum distance or use unmanned hose holders or monitor nozzles.
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.
For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn.

NFPA Extinguishing Methods for CAS5989-27-5 (NFPA, 2002):

Not Listed

NFPA Extinguishing Methods for CAS138-86-3 (NFPA, 2002):

Listed as: Dipentene
Extinguishing Method(s): Not Listed

Extinguish fires with foam, carbon dioxide, dry power, or vaporizing liquids (Prod Info, 1985).

COMBUSTION TOXICITY

Acrid fumes and smoke are released when limonene is heated to decomposition (Sax & Lewis, 1989).

EXPLOSION HAZARD

Limonene reacts violently with a combination of iodine tetrafluoride and tetrafluoroethylene (Sax & Lewis, 1989).

DUST/VAPOR HAZARD

Acrid fumes and smoke are released when limonene is heated to decomposition (Sax & Lewis, 1989).

REACTIVITY HAZARD

Limonene reacts with dry hydrogen chloride or hydrogen bromide to form monohalides (Windholz et al, 1983). It reacts with aqueous hydrogen chloride or hydrogen bromide to form dihalides (Windholz et al, 1983).

Limonene oxidizes to a film when exposed to the air (Sax & Lewis, 1987). Its behavior in oxidation is like that of drying oils or rubber (Sax & Lewis, 1987).

Limonene reacts violently with a combination of iodine tetrafluoride and tetrafluoroethylene (Sax & Lewis, 1989).

Acrid fumes and smoke are released when limonene is heated to decomposition (Sax & Lewis, 1989).

Limonene can be readily degraded in soil (Clayton & Clayton, 1982).

Hazardous polymerization does not occur with this material (Prod Info, 1985).

- ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area).
- All equipment used when handling the product must be grounded.
- Do not touch or walk through spilled material.
- Stop leak if you can do it without risk.
- Prevent entry into waterways, sewers, basements or confined areas.
- A vapor suppressing foam may be used to reduce vapors.
- Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers.
- Use clean non-sparking tools to collect absorbed material.
RECOMMENDED PROTECTIVE CLOTHING - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 128 (ERG, 2004)
- Wear positive pressure self-contained breathing apparatus (SCBA).
- Structural firefighters' protective clothing will only provide limited protection.

SMALL LEAK/SPILL

Apply a nonflammable dispersing agent to the spilled material and work into an emulsion with water and a brush (Prod Info, 1985).

LARGE LEAK/SPILL

LARGE SPILL PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 128 (ERG, 2004)
- Dike far ahead of liquid spill for later disposal.
- Water spray may reduce vapor; but may not prevent ignition in closed spaces.
Spread sand or earth to contain the spill and then collect the adsorbed material in a salvage container (Prod Info, 1985). The advice of a disposal company should then be sought for proper removal (Prod Info, 1985). The site should be ventilated after cleanup to dispel vapors (Prod Info, 1985).
