Hazards and Protection.
Store in a cool, dry place. Store in a tightly closed container.
Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes.
Skin: Wear appropriate gloves to prevent skin exposure. Clothing: Wear a chemical apron.
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.
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container.
Stable under normal temperatures and pressures.
Carbon monoxide, oxides of phosphorus, 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. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical 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).
Harmful if swallowed.
May cause respiratory tract irritation.
Harmful if absorbed through the skin.
May cause eye irritation.
Get medical aid. Wash mouth out with water.
Remove from exposure to fresh air immediately.
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
