TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Not combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION Risk of fire and explosion. if formulations contain flammable/explosive solvents

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT! AVOID EXPOSURE OF BREASTFEEDING WOMEN!

 •INHALATION Cough. Sore throat. See Ingestion.
Avoid inhalation of dust
Fresh air, rest. Seek medical attention if you feel unwell
 •SKIN MAY BE ABSORBED!
Protective gloves. Protective clothing.
Wear protective gloves when administering first aid. Remove contaminated clothes. Rinse and then wash skin with water and soap. Seek medical attention if you feel unwell
 •EYES Redness.
Face shield or eye protection in combination with breathing protection.
Rinse with plenty of water (remove contact lenses if easily possible).
 •INGESTION Headache. Nausea. Vomiting. Diarrhoea. Dizziness. Tremors. Convulsions.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Give a slurry of activated charcoal in water to drink, NOT if convulsions occur . Refer immediately for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance, chemical protection suit including self-contained breathing apparatus, protective gloves. Do NOT let this chemical enter the environment. Sweep spilled substance into non-metallic, sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place.
Well closed. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing. Separated from bases, metals, food and feedstuffs.
Do not transport with food and feedstuffs.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on contact with hot surfaces or flames, producing toxic and corrosive fumes including chlorine, hydrogen chloride and phosgene,

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: (Inhalable fraction), 0.5 mg/m³;
Peak limitation category: II(8);
skin absorption (H); (DFG 2009).
see Notes


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

INHALATION RISK:
A harmful concentration of airborne particles can be reached quickly when dispersed.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the central nervous system , resulting in convulsions

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the central nervous system, kidneys and liver. This substance is probably carcinogenic to humans.

ENVIRONMENTAL
DATA
Environmental Hazard placard The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur along the food chain, for example in fish and in seafood. The substance may cause long-term effects in the aquatic environment. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal.
N O T E S
This substance is a component of the insecticide hexachlorocyclohexane (mixed isomers). Carrier solvents used in commercial formulations may change physical and toxicological properties. The symptoms of convulsions do not become manifest until 0.5 to several hours. Do NOT take working clothes home. Do NOT use in the vicinity of a fire or a hot surface, or during welding.
Occupational Exposure Limits : MAK value is for technical mixture of alpha and beta isomers (0.5 mg/m3=(Conc.alpha-HCH divided by 5) + Conc beta-HCH)
