PROPIONITRILE

Most of the toxicity of propionitrile results from metabolic release of CYANIDE after systemic absorption. Onset of symptoms may therefore be delayed.

Expected effects of released CYANIDE include central nervous system and respiratory stimulation followed by depression, giddiness, headache, dyspnea, palpitations, vomiting, bradycardia, hypotension, coma, seizures, cardiac dysrhythmias, and metabolic acidosis. Cyanosis is generally a late sign, seen only at the stage of circulatory collapse and apnea.

Propionitrile ingestion causes perforating duodenal ulceration in animals. It is an eye irritant.

FIRST AID

CYANIDE POISONING

The treatment of propionitrile poisoning is essentially that for cyanide intoxication.
Establish respiration; avoid mouth-to-mouth resuscitation if possible during CPR to prevent self-poisoning. Immediately begin therapy with 100% oxygen. Be prepared for endotracheal intubation if necessary.
Rescuers must not enter areas with potential high airborne concentrations of this agent without self-contained breathing apparatus (SCBA) to avoid becoming secondary victims. Avoid direct dermal contact with cyanide contaminated patient or gastric contents.
Administer 100% oxygen: Establish secure large-bore IV.
A cyanide antidote, either hydroxocobalamin OR the sodium nitrite/sodium thiosulfate kit, should be administered to patients with symptomatic poisoning.
HYDROXOCOBALAMIN: ADULT DOSE: 5 g (two 2.5 g vials each reconstituted with 100 mL sterile 0.9% saline) administered as an intravenous infusion over 15 minutes. For severe poisoning, a second dose of 5 g may be infused intravenously over 15 minutes to 2 hours, depending on the patient's condition. CHILDREN: Limited experience; a dose of 70 mg/kg has been used in pediatric patients.
The Cyanide Antidote Kit is administered as follows:

SODIUM NITRITE: Adult: 10 mL (300 mg) of a 3% solution IV at a rate of 2.5 to 5 mL/minute; Child (with normal hemoglobin concentration): 0.2 mL/kg (6 mg/kg) of a 3% solution IV at a rate of 2.5 to 5 mL/minute, not to exceed 10 mL (300 mg).
Repeat one-half of initial sodium nitrite dose one-half hour later if there is inadequate clinical response. Calculate pediatric doses precisely to avoid potentially life-threatening methemoglobinemia. Use with caution if carbon monoxide poisoning is also suspected. Monitor blood pressure carefully. Reduce nitrite administration rate if hypotension occurs.
SODIUM THIOSULFATE: Administer sodium thiosulfate IV immediately following sodium nitrite. DOSE: ADULT: 50 mL (12.5 g) of a 25% solution; CHILD: 1 mL/kg (250 mg/kg) of a 25% solution, not to exceed 50 mL (12.5 g) total dose. A second dose, one-half of the first dose, may be administered if signs of cyanide toxicity reappear.

SODIUM BICARBONATE: Administer 1 mEq/kg IV to acidotic patients.
SEIZURES: Administer a benzodiazepine; DIAZEPAM (ADULT: 5 to 10 mg IV initially; repeat every 5 to 20 minutes as needed. CHILD: 0.1 to 0.5 mg/kg IV over 2 to 5 minutes; up to a maximum of 10 mg/dose. May repeat dose every 5 to 10 minutes as needed) or LORAZEPAM (ADULT: 2 to 4 mg IV initially; repeat every 5 to 10 minutes as needed, if seizures persist. CHILD: 0.05 to 0.1 mg/kg IV over 2 to 5 minutes, up to a maximum of 4 mg/dose; may repeat in 5 to 15 minutes as needed, if seizures continue).

Consider phenobarbital or propofol if seizures recur after diazepam 30 mg (adults) or 10 mg (children greater than 5 years).
Monitor for hypotension, dysrhythmias, respiratory depression, and need for endotracheal intubation. Evaluate for hypoglycemia, electrolyte disturbances, and hypoxia.

METHEMOGLOBINEMIA: Methylene or toluidine blue treatment may be considered if excessive methemoglobinemia occurs due to nitrite administration. Consider exchange transfusion for severe symptoms of excessive methemoglobinemia.
HYPERBARIC OXYGEN AND HEMODIALYSIS: May be useful in severe cases not responsive to supportive and antidotal therapy.
ACUTE LUNG INJURY: Maintain ventilation and oxygenation and evaluate with frequent arterial blood gases and/or pulse oximetry monitoring. Early use of PEEP and mechanical ventilation may be needed.
HYPOTENSION: Infuse 10 to 20 mL/kg isotonic fluid. If hypotension persists, administer dopamine (5 to 20 mcg/kg/min) or norepinephrine (ADULT: begin infusion at 0.5 to 1 mcg/min; CHILD: begin infusion at 0.1 mcg/kg/min); titrate to desired response.
ALTERNATE ANTIDOTES

Dicobalt-EDTA (Kelocyanor(R)) and 4-DMAP (4-dimethylaminophenol) are alternate cyanide antidotes in clinical use in various countries outside the USA.

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.
ACUTE LUNG INJURY: Maintain ventilation and oxygenation and evaluate with frequent arterial blood gases and/or pulse oximetry monitoring. Early use of PEEP and mechanical ventilation may be needed.

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).
Some chemicals can produce systemic poisoning by absorption through intact skin. Carefully observe patients with dermal exposure for the development of any systemic signs or symptoms and administer symptomatic treatment as necessary.

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.

ORAL/PARENTERAL EXPOSURE

In symptomatic patients, skip these steps until other major emergency measures including use of Cyanide Antidote Kit and other life support measures have been instituted.

Perform gastric lavage with a large bore tube after endotracheal intubation.
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.

ACTIVATED CHARCOAL: Administer charcoal as a slurry (240 mL water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents, 25 to 50 g in children (1 to 12 years), and 1 g/kg in infants less than 1 year old.

Administer 100% oxygen. Establish secure large bore IV.
A cyanide antidote, either hydroxocobalamin OR the sodium nitrite/sodium thiosulfate kit, should be administered to patients with symptomatic poisoning.
HYDROXOCOBALAMIN: ADULT DOSE: 5 g (two 2.5 g vials each reconstituted with 100 mL sterile 0.9% saline) administered as an intravenous infusion over 15 minutes. For severe poisoning, a second dose of 5 g may be infused intravenously over 15 minutes to 2 hours, depending on the patient's condition. CHILDREN: Limited experience; a dose of 70 mg/kg has been used in pediatric patients.
The Cyanide Antidote Kit is administered as follows:

SODIUM NITRITE: Adult: 10 mL (300 mg) of a 3% solution IV at a rate of 2.5 to 5 mL/minute; Child (with normal hemoglobin concentration): 0.2 mL/kg (6 mg/kg) of a 3% solution IV at a rate of 2.5 to 5 mL/minute, not to exceed 10 mL (300 mg).
Repeat one-half of initial sodium nitrite dose one-half hour later if there is inadequate clinical response. Calculate pediatric doses precisely to avoid potentially life-threatening methemoglobinemia. Use with caution if carbon monoxide poisoning is also suspected. Monitor blood pressure carefully. Reduce nitrite administration rate if hypotension occurs.
SODIUM THIOSULFATE: Administer sodium thiosulfate IV immediately following sodium nitrite. DOSE: ADULT: 50 mL (12.5 g) of a 25% solution; CHILD: 1 mL/kg (250 mg/kg) of a 25% solution, not to exceed 50 mL (12.5 g) total dose. A second dose, one-half of the first dose, may be administered if signs of cyanide toxicity reappear.

SODIUM BICARBONATE: Administer 1 mEq/kg IV to acidotic patients.
SEIZURES: Administer a benzodiazepine; DIAZEPAM (ADULT: 5 to 10 mg IV initially; repeat every 5 to 20 minutes as needed. CHILD: 0.1 to 0.5 mg/kg IV over 2 to 5 minutes; up to a maximum of 10 mg/dose. May repeat dose every 5 to 10 minutes as needed) or LORAZEPAM (ADULT: 2 to 4 mg IV initially; repeat every 5 to 10 minutes as needed, if seizures persist. CHILD: 0.05 to 0.1 mg/kg IV over 2 to 5 minutes, up to a maximum of 4 mg/dose; may repeat in 5 to 15 minutes as needed, if seizures continue).

Consider phenobarbital or propofol if seizures recur after diazepam 30 mg (adults) or 10 mg (children greater than 5 years).
Monitor for hypotension, dysrhythmias, respiratory depression, and need for endotracheal intubation. Evaluate for hypoglycemia, electrolyte disturbances, and hypoxia.

ACUTE LUNG INJURY: Maintain ventilation and oxygenation and evaluate with frequent arterial blood gases and/or pulse oximetry monitoring. Early use of PEEP and mechanical ventilation may be needed.
HYPOTENSION: Infuse 10 to 20 mL/kg isotonic fluid. If hypotension persists, administer dopamine (5 to 20 mcg/kg/min) or norepinephrine (ADULT: begin infusion at 0.5 to 1 mcg/min; CHILD: begin infusion at 0.1 mcg/kg/min); titrate to desired response.
HYPERBARIC OXYGEN AND HEMODIALYSIS: May be useful in severe cases not responsive to supportive and antidotal therapy.
If respiratory tract irritation or respiratory depression is evident, monitor arterial blood gases, chest x-ray, and pulmonary function tests.
Whole blood cyanide levels may be obtained to document the poisoning and response to treatment.
METHEMOGLOBINEMIA: Methylene or toluidine blue treatment may be considered if excessive methemoglobinemia occurs due to nitrite administration. Consider exchange transfusion for severe symptoms of excessive methemoglobinemia.

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 131 (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 and poison 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.
Propionitrile is a dangerous fire hazard when exposed to heat, flame (sparks), or oxidizers (Lewis, 1992).
Vapors may travel to a source of ignition and flash back (CHRIS , 1993).

FLAMMABILITY CLASSIFICATION

NFPA Flammability Rating for CAS107-12-0 (NFPA, 2002):

Listed as: Propionic Nitrile
Flammability Rating: 3

(3) Flammable. Liquids and solids that can be ignited under almost all ambient temperature conditions. Including liquids with a flash point below 73 degrees F and a boiling point above 100 degrees F, solid materials which form coarse dusts that burn rapidly without becoming explosive, materials which burn rapidly by reason of self-contained oxygen (ie, organic peroxides), and materials which ignite spontaneously when exposed to air.

FIRE CONTROL/EXTINGUISHING AGENTS

FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 131 (ERG, 2004)

CAUTION: All these products have a very low flash point: Use of water spray when fighting fire may be inefficient.

SMALL FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 131 (ERG, 2004)

Dry chemical, CO2, water spray or alcohol-resistant foam.

LARGE FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 131 (ERG, 2004)

Water spray, fog or alcohol-resistant foam.
Move containers from fire area if you can do it without risk.
Dike fire control water for later disposal; do not scatter the material.
Use water spray or fog; do not use straight streams.

TANK OR CAR/TRAILER LOAD FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 131 (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 CAS107-12-0 (NFPA, 2002):

Listed as: Propionic Nitrile
Extinguishing Method(s): 1

1: "Water may be ineffective" applies to a situation where materials with a flash point below 100 degrees F (37.8 degrees C) are burning. Water will only be effective if used by experienced fire fighters under favorable conditions. Even though water may not put the fire out, it can be used to protect equipment and structures.

To fight fire, use water spray, foam, mist, carbon dioxide, or dry chemical (Lewis, 1992).

COMBUSTION TOXICITY

When heated to decomposition, propionitrile emits toxic fumes of cyanide and oxides of nitrogen (Lewis, 1992).

EXPLOSION HAZARD

Propionitrile is a vapor explosion and poison hazard indoors, outdoors, or in sewers (CHRIS , 1993).

Mixture with N-bromosuccinimide may explode when heated (Lewis, 1992).

DUST/VAPOR HAZARD

Vapor (gas) irritant characteristics: Vapors cause severe irritation of eyes and throat and can cause eye and lung injury. They cannot be tolerated even at low concentrations (CHRIS , 1993).

Vapors may travel to a source of ignition and flash back (CHRIS , 1993).

Propionitrile is a vapor explosion and poison hazard indoors, outdoors or in sewers (CHRIS , 1993).

REACTIVITY HAZARD

Propionitrile releases hydrogen cyanide when in contact with acids (Windholz et al, 1983).

Propionitrile is a fire hazard when in contact with oxidizers (Sax, 1984).

Propionitrile is poisonous when heated to decomposition or on contact with acids (Budavari, 1989).

When heated to decomposition, propionitrile emits toxic fumes of cyanide and oxides of nitrogen (Lewis, 1992).

CONTAINMENT/WASTE TREATMENT OPTIONS

SUMMARY

SPILL OR LEAK PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 131 (ERG, 2004)
- Fully encapsulating, vapor protective clothing should be worn for spills and leaks with no fire.
- 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.
RECOMMENDED PROTECTIVE CLOTHING - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 131 (ERG, 2004)
- Wear positive pressure self-contained breathing apparatus (SCBA).
- Wear chemical protective that is specifically recommended by the manufacturer. It may provide little or no thermal protection.
- Structural firefighters' protective clothing provides limited protection in fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible.

SMALL LEAK/SPILL

SMALL SPILL PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 131 (ERG, 2004)
- Absorb with earth, sand or other non-combustible material and transfer to containers for later disposal.
- Use clean non-sparking tools to collect absorbed material.

LARGE LEAK/SPILL

LARGE SPILL PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 131 (ERG, 2004)
- Dike far ahead of liquid spill for later disposal.
- Water spray may reduce vapor; but may not prevent ignition in closed spaces.

WASTE TREATMENT OPTIONS

CHEMICAL TREATMENT

Hazardous Waste Disposal: Generators of waste in quantities equal to or greater than 100 kg/month containing propionitrile, EPA hazardous waste number P101, must conform with US Environmental Protection Agency regulations in storage, transportation, treatment, and disposal of waste ((HSDB, 1993)).
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.

BIOREMEDIATION

Biological treatment has been investigated as a potential wastewater treatment technology for propionitrile ((HSDB, 1993)).

PHYSICAL TREATMENT

Propionitrile 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, 1993)).
Propionitrile is 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, 1993)).
Propionitrile is 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 hours for solids ((HSDB, 1993)).

-ENVIRONMENTAL HAZARD MANAGEMENT

POLLUTION HAZARD

Propionitrile may be released to the environment as fugitive emissions or in wastewater during its byproduct formation during the electro-reduction of acrylonitrile to form adiponitrile. Human exposure will most likely be via inhalation in occupational settings ((HSDB, 1993)).

WATER: Propionitrile is harmful to aquatic life at low concentrations. It may be dangerous if it enters water intakes. Notify local health and wildlife officials. Notify operators of local water intakes (CHRIS , 1993).

ENVIRONMENTAL FATE AND KINETICS

If released into the atmosphere, propionitrile will degrade very slowly due to reaction with hydroxyl radicals (half-life 83 days). Due to its high water solubility, 2.14 moles/L, it should be scavenged from the air by rain ((HSDB, 1993)).

WATER

SURFACE WATER
- If released into water, propionitrile would volatilize (half-life: 20 hours in a model river one meter deep). Biodegradation is possible but there is no supporting evidence from studies in environmental waters. Adsorption to the sediment, bioconcentration, and hydrolysis would not be significant ((HSDB, 1993)).

SOIL

TERRESTRIAL
- If released on land, propionitrile would be expected to leach readily into the groundwater and/or evaporate. It is reported to biodegrade rapidly in a screening study, and, therefore biodegradation in soil may be an important degradation process ((HSDB, 1993)).

OTHER

OTHER
- AIR: The half-life of propionitrile in the atmosphere due to reaction with hydroxyl radicals is 83 days ((HSDB, 1993)).
- WATER: The half-life of propionitrile in water via volatilization is 20 hours from a model river one meter deep ((HSDB, 1993)).
