Hazards and Protection.
Storage
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Protective gloves and clothing were developed in order to reduce the hazard of industrial use of triaryl phosphate.
Respirators
Respiratory protection (supplied-air respirator with full facepiece or self-contained breathing apparatus) should be available where these compounds are manufactured or used and should be worn in case of emergency and overexposure.
Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Do not use water. Apply water spray or mist to knock down vapors. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash, cement powder, or commercial sorbents. Water spill: Use natural barriers or oil spill control booms to limit spill travel. Remove trapped material with suction hoses.
Stability

Fire fighting
Do not extinguish fire unless flow can be stopped. Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide. Keep run-off water out of sewers and water sources.
Hazards
Toxic acidic vapors may form.
Combustion products
Toxic acidic vapors may form.

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).
   Ingestion
Abdominal pain, nausea, and vomiting often occur. Diarrhea may last several weeks.
   Inhalation
Breathing or swallowing large quantities may cause ataxia. May irritate skin, respiratory tract, mucous membrane, and eyes.
   Skin
The soles of the feet and palms may be cold, cyanotic, and profusely diaphoretic.
   Eyes
See inhalation

First aid
 
   Ingestion
DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, administer a slurry of activated charcoal in water and simultaneously call a hospital or poison control center. IMMEDIATELY transport the victim to a hospital.
   Inhalation
IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used.
   Skin
IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.
   Eyes
First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
