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. Further see Ingestion.
Avoid inhalation of dust
Fresh air, rest. Refer for medical attention.
 •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. Refer for medical attention.
 •EYES Redness.
Face shield or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION Nausea. Vomiting. Diarrhoea. Headache. Dizziness. Tremor 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, but 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 STATE; APPEARANCE:
WHITE CRYSTALLINE POWDER .

PHYSICAL DANGERS:


CHEMICAL DANGERS:
On contact with hot surfaces or flames this substance decomposes forming toxic and corrosive fumes including chlorine, hydrogen chloride and phosgene (See ICSCs #0007, #0126 and #0163.) Reacts with bases , producing trichlorobenzene , and with powdered metals .

OCCUPATIONAL EXPOSURE LIMITS:
OSHA PEL: TWA 0.5 mg/m3 skin
NIOSH REL: TWA 0.5 mg/m3 skin
NIOSH IDLH: 50 mg/m3 See: 58899
TLV: 0.5 mg/m³ as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2009).
MAK: 0.1 mg/m³; (Inhalable fraction);
Peak limitation category: II(8);
skin absorption (H);
Carcinogen category: 4; Pregnancy risk group: C; BAT issued;
(DFG 2009).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. 507

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. Exposure may result in death. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the the nervous system, bone marrow and the liver . Tumours have been detected in experimental animals but may not be relevant to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development. tter size in 2nd generation mice in mice when given orally (http://monographs.iarc.fr/ENG/Monographs/suppl7/Suppl7-88.pdf)

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
Depending on the degree of exposure, periodic medical examination is suggested. Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home. Do NOT use in the vicinity of a fire or a hot surface, or during welding. See also ICSC #0487 Hexachlorocyclohexane (mixed isomers), #0795 alpha-Hexachlorocyclohexane, #0796 beta-Hexachlorocyclohexane .
