Hazards and Protection.
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation.
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.
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.
Clean up spills immediately, using the appropriate protective equipment. Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Provide ventilation.
Stable under normal temperatures and pressures.
Carbon monoxide, oxides of phosphorus, irritating and toxic fumes and gases, carbon dioxide.
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. Extinguishing media: Use agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
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).
May cause irritation of the digestive tract. The toxicological properties of this substance have not been fully investigated.
May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated.
May cause skin irritation.
May cause eye irritation.
Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
