List of data sources.
Firefighting
(Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) Wear positive pressure breathing apparatus and special protective clothing. Move container from fire area. Fight fire from maximum distance. Dike fire control water for later disposal; do not scatter the material.

Extinguish with dry chemical, carbon dioxide, water spray, fog or foam. (EPA, 1998)
Non-Fire Response
(Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) Keep unnecessary people away; stay upwind. Do not touch spilled material; stop leak if possible. Use water spray to reduce vapors. Take up with noncombustible absorbent material. For large spills, dike far ahead of spill. (EPA, 1998)
Protective Clothing
Skin: Wear appropriate personal protective clothing to prevent skin contact.

Eyes: Wear appropriate eye protection to prevent eye contact.

Wash skin: The worker should immediately wash the skin when it becomes contaminated.

Remove: Work clothing that becomes wet or significantly contaminated should be removed and replaced.

Change: No recommendation is made specifying the need for the worker to change clothing after the work shift.

Provide: Eyewash fountains should be provided in areas where there is any possibility that workers could be exposed to the substance; this is irrespective of the recommendation involving the wearing of eye protection. Facilities for quickly drenching the body should be provided within the immediate work area for emergency use where there is a possibility of exposure. [Note: It is intended that these facilities provide a sufficient quantity or flow of water to quickly remove the substance from any body areas likely to be exposed. The actual determination of what constitutes an adequate quick drench facility depends on the specific circumstances. In certain instances, a deluge shower should be readily available, whereas in others, the availability of water from a sink or hose could be considered adequate.] (NIOSH, 2003)
First Aid
Warning: Effects may be delayed up to 12 hours. Caution is advised.

Note: Fensulfothion is a cholinesterase inhibitor.

Signs and Symptoms of Fensulfothion Exposure: Acute exposure to fensulfothion may produce the following signs and symptoms: sweating, pinpoint pupils, blurred vision, headache, dizziness, profound weakness, muscle spasms, seizures, and coma. Mental confusion and psychosis may occur. Excessive salivation, nausea, vomiting, anorexia, diarrhea, and abdominal pain may also occur. The heart rate may decrease following oral exposure or increase following dermal exposure. Chest pain may be noted. Hypotension (low blood pressure) may be observed, although hypertension (high blood pressure) is not uncommon. Respiratory symptoms include dyspnea (shortness of breath), pulmonary edema, respiratory depression, and respiratory paralysis.

Emergency Life-Support Procedures: Acute exposure to fensulfothion exposure may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination. Air-purifying or supplied-air respiratory equipment should also be worn, as necessary.
