Metasystox health hazards: This product is a highly toxic organophosphorus insecticide. Inhibits cholinesterase activity. Poisoning and recuperation include headache, dizziness, fatigue, nausea and vomiting, abdominal pain, salivation, sweating, blurred vision, miosis, muscle fasciculation, and even pulmonary edema and coma.
Toxicological data and environmental behavior of metasystox
Toxicity: It is a moderately toxic category. It has anesthesia and inhibits the activity of cholestyrase.
Acute toxicity of metasystox: LD50 50～75mg/kg (rat oral); 300～450mg/kg (rat percutaneous)
Hazardous characteristics of metasystox: flammable in case of open flame and high heat. Decomposed by high heat to produce toxic and corrosive fumes.
Combustion (decomposition) products: carbon monoxide, carbon dioxide, sulfur oxides, phosphorus oxides.
Emergency treatment of metasystox leakage
Evacuate personnel from the leaked contaminated area to a safe area, and prohibit irrelevant personnel from entering the contaminated area. It is recommended that emergency responders wear self-contained breathing apparatus and chemical protective clothing. Spray water to reduce evaporation. Do not directly contact the leakage, mix it with sand or other non-combustible absorbent, collect it and bury it in an open place. The contaminated ground is scrubbed with soap or detergent, and the diluted sewage is put into the wastewater system. If there is a large spill, carefully sweep up and place in a spare bag.
Protective measures for metasystox
Respiratory Protection: Wear a gas mask when possible exposure to its vapors. When the concentration in the air is high, self-contained breathing apparatus should be worn.
Eye Protection: Wear chemical safety goggles.
Body Protection: Wear appropriate protective clothing.
Hand Protection: Wear chemical resistant gloves.
Others: Smoking, eating and drinking are prohibited at the workplace. After work, shower and change. Do not bring work clothes to non-working places, store clothes contaminated by poisons separately, and use them after washing. Practice good hygiene.
