Summaries only, follow the supplier SDS for your grade

Safe handling

General: PREVENT DISPERSION OF DUST! STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR!

Inhalation: Use local exhaust or breathing protection.

Skin: Protective gloves. Protective clothing.

Eyes: Wear face shield or eye protection in combination with breathing protection if powder.

Ingestion: Do not eat, drink, or smoke during work. Wash hands before eating.

Storage

Separated from food and feedstuffs. Well closed. Keep in a well-ventilated room. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing.

Disposal

Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number P051, D012, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste. The reductive dechlorination of dieldrin and endrin was investigated as a possible procedure for field disposal of small quantities of these pesticides. The objective was to convert the parent compounds to environmentally less objectionable materials. Emulsifiable concentrate formulations of the pesticides in a soil slurry were mixed with powdered zinc, dilute acetic acid, and acetone to facilitate reaction. Analysis of the mixtures by GC-MS indicated essentially complete conversion of endrin and partial conversion of dieldrin to products probably formed by replacement of the bridge anti-chlorines with hydrogen.
