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

EXPOSURE		PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
Inhalation	See Ingestion.	Use ventilation (not if powder).	Fresh air, rest. Refer for medical attention.
Skin	MAY BE ABSORBED! See Ingestion.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .
Eyes		Wear safety goggles or face shield.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Convulsions. Dizziness. Headache. Nausea. Vomiting. Muscle twitching.	Do not eat, drink, or smoke during work. Wash hands before eating.	Give a slurry of activated charcoal in water to drink. Do NOT induce vomiting. Rest. Refer for medical attention .

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Do NOT wash away into sewer. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Personal protection: chemical protection suit including self-contained breathing apparatus.	Do not transport with food and feedstuffs. Severe marine pollutant. EC Classification Symbol: T+, N; R: 25-27-40-48/25-50/53; S: (1/2)-22-36/37-45-60-61 UN Classification UN Hazard Class: 6.1; UN Pack Group: II GHS Classification

EMERGENCY RESPONSE	SAFE STORAGE
Transport Emergency Card: TEC (R)-61G41B.	Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs and incompatible materials. See Chemical Dangers. Well closed. Keep in a well-ventilated room. Store in an area without drain or sewer access.

IMPORTANT DATA

Physical State; Appearance
COLOURLESS CRYSTALS.

Physical dangers

Chemical dangers
Decomposes on heating. This produces toxic fumes including hydrogen chloride. Reacts with oxidants and acids. Attacks metals due to the slow formation of hydrogen chloride in storage.

Occupational exposure limits
TLV: 0.25mg/m³ as TWA; (skin); A4 (not classifiable as a human carcinogen); (ACGIH 2000).
MAK (inhalable fraction): 0.25 mg/m³; Peak limitation category: II(8); Skin absorption (H); (DFG 2007).

Routes of exposure
The substance can be absorbed into the body through the skin and by ingestion.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.

Effects of short-term exposure
The substance may cause effects on the central nervous system. This may result in convulsions. Medical observation is indicated.

Effects of long-term or repeated exposure
Cumulative effects are possible. See Acute Hazards/Symptoms.

PHYSICAL PROPERTIES

ENVIRONMENTAL DATA

Melting point: 175-176°C
Density: 1.7 g/cm³
Solubility in water: none
Vapour pressure, Pa at 20°C: 0.0004
Octanol/water partition coefficient as log Pow: 6.2

The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to bees and birds. Bioaccumulation of this chemical may occur in aquatic organisms. It is strongly advised not to let the chemical enter into the environment because it is persistent. The substance may cause long-term effects in the aquatic environment. Avoid release to the environment in circumstances different to normal use.

NOTES

Depending on the degree of exposure, periodic medical examination is indicated.
If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s).
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Do NOT take working clothes home.
Alvit, Dieldrex, Dieldrite, Illoxol, Octalox, Panoram, and Quintox are trade names.
Also consult ICSC #0774, Aldrin.
Card has been partially updated in August 2007: see Storage, Occupational Exposure Limits.
