If adverse effects occur, remove to uncontaminated area. Give artificial respiration if not breathing. If breathing is difficult, oxygen should be administered by qualified personnel. Get immediate medical attention. 

Emergency responders should wear gloves and avoid contamination. Remove contaminated clothing, jewelry, and shoes immediately. Artificial respiration (rescue breathing) may be needed. Wash contaminated areas with soap and water. Get medical attention immediately. 

Wash eyes immediately with large amounts of water or normal saline, occasionally lifting upper and lower lids, until no evidence of chemical remains. Get medical attention immediately. 

If vomiting occurs, keep head lower than hips to help prevent aspiration. Use a bag valve mask or similar device to perform artificial respiration (rescue breathing) if needed. Contact local poison control center or physician immediately. Get medical attention immediately. 

For inhalation, consider oxygen. For ingestion, consider gastric lavage. Consider oxygen. Avoid depressants. 

See Section 9 for Flammability Properties 

Negligible fire hazard. 

regular dry chemical, regular foam, water 

Large fires: Use regular foam or flood with fine water spray. 

Move container from fire area if it can be done without risk. Fight large fires from a protected location or safe distance. Stay away from the ends of tanks. Dike for later disposal. Do not scatter spilled material with high-pressure water streams. Do not attempt to extinguish fire unless flow of material can be stopped first. Use extinguishing agents appropriate for surrounding fire. Flood with fine water spray. Cool containers with water spray until well after the fire is out. Apply water from a protected location or from a safe distance. Avoid inhalation of material or combustion by-products. Stay upwind and keep out of low areas. Consider downwind evacuation if material is leaking. 

Do not touch spilled material. Stop leak if possible without personal risk. Reduce vapors with water spray. Small spills: Absorb with sand or other non-combustible material. Collect spilled material in appropriate container for disposal. Small dry spills: Move containers away from spill to a safe area. Large spills: Dike for later disposal. Keep unnecessary people away, isolate hazard area and deny entry. Ventilate closed spaces before entering. Notify Local Emergency Planning Committee and State Emergency Response Commission for release greater than or equal to RQ (U.S. SARA Section 304). If release occurs in the U.S. and is reportable under CERCLA Section 103, notify the National Response Center at (800)424-8802 (USA) or (202)426-2675 (USA). 

Store and handle in accordance with all current regulations and standards. May be subject to EPA pesticide registration. Notify State Emergency Response Commission for storage or use at amounts greater than or equal to the TPQ (U.S. EPA SARA Section 302). SARA Section 303 requires facilities storing a material with a TPQ to participate in local emergency response planning (U.S. EPA 40 CFR 355 Part B). Keep separated from incompatible substances.

ORGANOPHOSPHATES: When inhaled, the first effects of cholinesterase inhibitors are usually respiratory and may include nasal hyperemia and watery discharge, cough, chest discomfort, dyspnea, and wheezing due to increased bronchial secretions and bronchoconstriction If sufficient amounts are absorbed, other systemic effects may begin within a few minutes or be delayed for up to 12 hours Symptoms may include pallor, nausea, vomiting, diarrhea, abdominal cramps, headache, dizziness, ocular pain, blurred vision, miosis or in some cases, especially initially, mydriasis, lacrimation, salivation, sweating, and confusion Other reported central nervous system or neuromuscular effects may include ataxia, slurred speech, areflexia, weakness, fatigue, fasciculations, twitching, tremors possibly of the tongue and eyelids, and eventually paralysis of the extremities and possibly of the respiratory muscles In severe cases there may also be involuntary defecation and urination, cyanosis, psychosis, hyperglycemia, acute pancreatitis, cardiac irregularities, pulmonary edema, unconsciousness, convulsions, and coma Death is primarily due to respiratory failure, although cardiovascular effects including cardiac arrest may also be implicated Long term sequelae are rare but may include neuropsychiatric disorders and myopathy with muscle tenderness Some organophosphates may cause a delayed neuropathy beginning 1-4 weeks after an acute exposure which may or may not have caused acute cholinergic effects Numbness, tingling, weakness and cramping beginning symmetrically in the lower limbs may progress to ataxia and paralysis In severe cases, upper limb involvement is possible and flaccid paralysis may progress to spastic paralysis with exaggerated reflexes Improvement may occur over months to years, but some residual impairment usually remains.

ORGANOPHOSPHATES: Repeated or prolonged exposure may result in the effects of acute exposure including the delayed neuropathy Other effects reported in workers repeatedly exposed include impaired memory and concentration, acute psychosis, severe depressions, irritability, confusion, apathy, emotional lability, social withdrawal, confusion, headache, speech difficulties, delayed reaction times, spatial disorientation, nightmares, sleepwalking, and drowsiness or insomnia An influenza-like condition with headache, nausea, weakness, anorexia and malaise has also been reported.

SULFOTEP (TEDP) See information on organophosphates.

ORGANOPHOSPHATES: Localized sweating and fasciculations may occur at the site of contact If sufficient amounts are absorbed, other effects of cholinesterase inhibition as described in acute inhalation may occur Symptoms may be delayed 2-3 hours, but usually no more than 12 hours The rate of absorption is increased by the presence of dermatitis or high ambient temperatures Delayed neuropathy is also possible.

ORGANOPHOSPHATES: Repeated or prolonged exposure may cause effects as described in acute exposure Some organophosphates may cause sensitization.

SULFOTEP (TEDP) See information on organophosphates.

ORGANOPHOSPHATES: Direct contact may cause pain, hyperemia, lacrimation, twitching of the eyelids, miosis, and ciliary muscle spasm with loss of accomodation, blurred or dimmed vision and browache Sometimes mydriasis may occur instead of miosis With sufficient exposure, other symptoms of cholinesterase inhibition as described in acute inhalation may occur.

ORGANOPHOSPHATES: Repeated or prolonged exposure may cause effects as described in acute exposure Some compounds have caused toxic effects on the crystalline lens, conjunctival thickening and obstruction of the nasolacrimal canals when used as miotic eyedrops.

SULFOTEP (TEDP) See information on organophosphates.

ORGANOPHOSPHATES: When ingested, the first effects may be nausea, vomiting, anorexia, abdominal cramps and diarrhea Gastrointestinal absorption may cause symptoms of cholinesterase inhibition as described in acute inhalation Symptoms may begin within minutes or be delayed for hours Delayed effects including neuropathy may also occur.

ORGANOPHOSPHATES Repeated ingestion may cause effects as described in acute exposure.
