Hazards and Protection.
Storage
Keep in well ventilated area.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Employees should be provided with and required to use dust- and splash-proof safety goggles where there is any possibility of contacting the eyes. Employees should be provided with and required to use impervious clothing, gloves, face shields (eight inch minimum), and other appropriate protective clothing necessary to prevent any possibility of skin contact. Wear boots, protective gloves, and goggles.
Respirators
Self-contained breathing apparatus with a full facepiece operated in pressure-demand or other positive pressure mode, or a combination respirator which includes a type c supplied-air respirator with a full facepiece operated in pressure-demand or other positive pressure or continous-flow mode and an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive pressure mode.
Small spills/leaks
Material is related to aldrin. (Non-Specific -- Aldrin) Stay upwind; keep out of low areas. Ventilate closed spaces before entering them. Remove and isolate contaminated clothing at the site. Do not touch spilled material; stop leak if you can do it without risk. Use water spray to reduce vapors. Small spills: take up with sand or other noncombustible absorbent material and place into containers for later disposal. Small dry spills: with clean shovel place material into clean, dry containers and cover; move containers from spill area. Large spills: dike far ahead of spill for later disposal.
Stability
Is not a stable molecule.

Fire.
Fire fighting
(Non-Specific -- Aldrin) Wear full protective clothing, including positive pressure breathing apparatus. Move container from fire area if you can do so without risk. Fight fire from maximum distance. Dike fire control water for later disposal; do not scatter the material.Material is related to aldrin. (Non-Specific -- Aldrin) Extinguish by using water spray, dry chemical, foam, or carbon dioxide. Use water to keep fire exposed containers cool.
Fire potential
Non-Combustible
Combustion products
Fire may produce irritating, corrosive and/or toxic gases.

Exposure effects
Respiratory depression can occur from aldrin, dieldrin, endrin, and presumably isodrin. Elevated body temperature, elevated blood pressure, or abnormally low blood pressure may occur. Excitation with myoclonic jerking and convulsions may occur. In extreme overdose CNS depression and coma may occur. Permanent damage may occur from acute exposure. No data were available to assess the teratogenic potential of this agent. <br>No data were available to assess the potential effects of exposure to this agent during pregnancy or lactation.
   Ingestion
Nausea, vomiting, and diarrhea may occur following ingestion.
   Inhalation
Irritation, reduced gas exchange, and chemical pneumonitis may occur.
   Skin
Extensive contact results in dermal irritation. Isodrin may cause acne and skin rashes.
   Eyes
Hypersalivation, headache, and foaming from the mouth or nose may occur.

First aid
 
   Ingestion
Seek medical assistance.
   Inhalation
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
   Skin
If clothing is contaminated remove, and wash skin and hair three times; do an initial soap washing followed by an alcohol washing followed by a soap washing. Leather absorbs pesticides. Hence, leather should not be worn in the presence of pesticides and all contaminated leather should be discarded. See treatment of dermal exposure in the main body of this document for complete information.
   Eyes
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
