NOAA NUMBER -- 4934

CHEMICAL NAME -- CYANOPHOS

CHEMICAL ABSTRACT SERVICES REGISTRY NUMBER -- 2636262

GENERAL DESCRIPTION OF A CHEMICAL
Yellow to reddish-yellow transparent liquid. Use: This material is
an insecticide used against rice stem borers and house flies. Not
registered as a pesticide in the U.S. (EPA, 1986)

FIRE AND EXPLOSION HAZARDS
(Non-specific -- Organophosphorus pesticide, liquid, n.o.s.) This
material may burn, but does not ignite readily. Container may
explode in heat of fire. Fire and runoff from fire control water
may produce irritating or poisonous gases. Rapidly decomposes
under alkaline conditions and upon exposure to light. (EPA, 1986)

FIRE FIGHTING TECHNIQUES
(Non-specific -- Organophosphorus pesticide, liquid, n.o.s.) For
small fires, use dry chemical, carbon dioxide, water spray, or
foam. For large fires, use water spray, fog, or foam. Move
container from fire area if you can do it without risk. Fight fire
from maximum distance. Dike fire control water for later disposal;
do not scatter the material. (EPA, 1986)

PROTECTIVE CLOTHING RECOMMENDATIONS
(Non-specific -- Organophosphorus pesticide, liquid, n.o.s.) Wear
positive pressure breathing apparatus and special protective
clothing. Remove and isolate contaminated clothing at the site.
(EPA, 1986)

COMPATIBILITY WITH POLYETHYLENE -- Poor Resistance/Limited Data.

COMPATIBILITY WITH POLYURETHANE -- Poor Resistance/Limited Data.

EVACUATION INFORMATION
(Non-specific -- Organophosphorus pesticide, liquid, N.O.S.) Stay
upwind; keep out of low areas. (EPA, 1986)

NON-FIRE RESPONSE INFORMATION
(Non-specific -- Organophosphorus pesticide, liquid, n.o.s.)
Ventilate closed spaces before entering them. Do not touch spilled
material. Use water spray to reduce vapors. Take up small spills
with sand or other noncombustible absorbent material and place in
containers for later disposal. Dike far ahead of large spills for
later disposal. (EPA, 1986)

HEALTH HAZARD INFORMATION
Cyanophos is an organophosphorus insecticide. It is a
cholinesterase inhibitor. Death may occur after a massive oral
dose; with smaller accidental doses, onset of illness may be
delayed. Signs and Symptoms of Exposure: Symptoms of
organophosphorus pesticide poisoning include: Headache, giddiness,
nervousness, blurred vision, weakness, nausea, cramps, diarrhea,
and discomfort in the chest. Signs include: Sweating, pinpoint
pupils, tearing, salivation and other excessive respiratory tract
secretion, vomiting, cyanosis, papilledema, uncontrollable muscle
twitches followed by muscular weakness, convulsions, coma, loss of
reflexes, and loss of sphincter control. (EPA, 1986)

FIRST AID INFORMATION
Move victim to fresh air; call emergency medical care. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. In case of contact with material, immediately flush
skin or eyes with running water for at least 15 minutes. Speed in
removing material from skin is of extreme importance. Remove and
isolate contaminated clothing and shoes at the site. Keep victim
quiet and maintain normal body temperature. Effects may be
delayed; keep victim under observation. (EPA, 1986)
