Description of first aid measures
If inhaledMove the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.

Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms and effects, both acute and delayed
SYMPTOMS: Symptoms of exposure to this material include increased perspiration, nausea, lachrymation, salivation, blurred vision, diarrhea, pulmonary edema, respiratory embarrassment and convulsions. ACUTE/CHRONIC HAZARDS: This material may be absorbed through the skin and is a lachrymator. It is a cholinesterase inhibitor. This compound is a positive animal carcinogen. (NTP, 1992)
Indication of any immediate medical attention and special treatment needed
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Organophosphates and related compounds
Extinguishing media
Fires involving this compound should be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)

Persistence and degradability
AEROBIC: In the environment, the main route of loss of tetrachlorvinphos is via biodegradation, with a soil half-life of 4.4 days using a Blackord loam soil and <8 days using a medium loam soil(1). Degradation of tetrachlorvinphos in soil is believed to be microbially mediated based on the observation that the rate of loss is greater than would be expected on the basis of in-vitro hydrolysis studies(2). The degradation pathway involves the cleavage of the P-O-C(alkyl) bond(2).
Bioaccumulative potential
An estimated BCF of 17 was calculated in fish for tetrachlorvinphos(SRC), using a log Kow of 3.53(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of tetrachlorvinphos is estimated as 2,000(SRC), using a log Kow of 3.53(1) and a regression-derived equation(2). A calculated Koc of 1,170 based on a water solubility of 11 ppm has also been reported(3). According to a classification scheme(3), these estimated Koc values suggest that tetrachlorvinphos is expected to have low mobility in soil.
Other adverse effects

Disposal methods
ProductThe material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
