SECTION 2: Hazards identification

EMERGENCY OVERVIEW: CAUTION: Contains a Cholinesterase Inhibitor. Repeated inhalation or skin contact with Dichlorvos (DDVP) may, without symptoms, progressively increase susceptibility to Dichlorvos (DDVP) poisoning. May be Toxic to fish, birds, and other wildlife when exposed to large quantities of strips.

Principle Routes of Exposure

Under normal use conditions the amount of DDVP given off by the product described in this MSDS is not sufficient to cause ingestion, skin, eye or inhalation hazards. However, under extreme conditions this product may be fatal if sufficient DDVP is absorbed through the eye or skin, is ingested or is inhaled. Overexposure may produce acute cholinesterase depression. SIGNS OF ACUTE OVEREXPOSURE: Acute cholinesterase depression may be evidenced by headache, nausea, vomiting, diarrhea, abdominal cramps, excessive sweating, salivation and tearing, constricted pupils, blurred vision, tightness in chest, weakness, muscle twitching and confusion; in extreme cases, unconsciousness, convulsions, severe respiratory depression and death may occur. SIGNS OF CHRONIC OVEREXPOSURE: Repeated exposures to small doses of DDVP and other organophosphates may lower the cholinesterase to levels where the above symptoms of acute overexposure are observed. CARCINOGENICITY: EPA under its 1999 proposed Guidelines for Carcinogen Risk Assessment has classified DDVP as having "suggestive evidence of carcinogenicity, but not sufficient to assess human carcinogenic potential." IARC lists DDVP (Dichlorvos) as being possibly carcinogenic to humans (Group 2B). CARE SHOULD BE EXERCISED IN HANDLING DDVP AND ITS FORMULATIONS. MEDICAL CONDITIONS POTENTIALLY AGGRAVATED BY EXPOSURE: Preexisting conditions which lower cholinesterase levels increase vulnerability to cholinesterase depression. These include: (for plasma) genetic cholinesterase deficiency; advanced liver disease; chronic alcoholism; malnutrition; dermatomyositis; existing toxicity from exposure to carbon disulfide; benzalkonium salts, organic mercury compounds, ciguatoxins or solanines; and (for RBC) hemolytic anemias.
