First Aid Measures

Ingestion
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation
Remove from exposure to fresh air immediately. Get medical aid if cough or other symptoms appear.
Skin
Get medical aid immediately. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Discard contaminated clothing in a manner which limits further exposure.
Eyes
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed.

Handling and Storage

Storage
Keep container closed when not in use. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
Handling
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Do not ingest or inhale.

Hazards Identification

Inhalation
Causes respiratory tract irritation. Low hazard for usual industrial handling.
Skin
Causes skin burns. May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material.
Eyes
Causes eye burns.
Ingestion
Harmful if swallowed. May cause irritation of the digestive tract. May inhibit cholinesterase activity, thereby producing nervous system effects.
Hazards
Contact with metals may evolve flammable hydrogen gas.

Exposure Controls/Personal Protection

Personal Protection
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
Respirators
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Exposure Effects
A delayed peripheral neuropathy of the dying back or peripheral axonopathy variety predominates. Between 10 and 40 days after exposure, abrupt onset of flaccid paralysis is noted. This may be followed by lower extremity spasticity with clonus, hyperreflexia, hypertonus, and a peculiar spastic gait. In severe cases the full extent of paralysis may not be reached until after 2 to 3 months. Recovery is variable. Mortality is usually low and approximately 5% of victims may remain paralyzed. TOCP produced toxic effects on both male and female REPRODUCTIVE SYSTEMS when Long-Evans rats were given doses of 0 to 400 mg/kg by gavage prior to, and during breeding. Spermatotoxic effects, includes reduced motility, concentration, velocity, and abnormal morphology. Damage to ovarian and uterine tissue also 1999).

Fire Fighting Measures

Flash Point
188
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. To extinguish fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
Fire Potential
This chemical is combustible.

Accidental Release Measures

Small spills/leaks
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Clean up spills immediately, using the appropriate protective equipment. Provide ventilation.

Stability and Reactivity

Disposal Code
25
Stability
Stable under normal temperatures and pressures.
Incompatibilities
Strong oxidizing agents.
Decomposition
Carbon monoxide, oxides of phosphorus, carbon dioxide.
Combustion Products
Fire may produce irritating, corrosive and/or toxic gases.
