  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION 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.   

 PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!  
  SYMPTOMS PREVENTION FIRST AID
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 CLASSIFICATION & 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.

Melting point: 104-105°C
Density: 1.6 g/cm³
Solubility in water: none
Vapour pressure, Pa at 20°C: 0.009
Octanol/water partition coefficient as log Pow: 7.4  


EXPOSURE & HEALTH EFFECTS

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

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

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

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


OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.05 mg/m3, as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans).
MAK: (inhalable fraction): 0.25 mg/m3; peak limitation category: II(8); skin absorption (H) 

ENVIRONMENT
The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to birds and bees. 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
Other melting points: 49-60°C (technical grade).
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.
The recommendations on this Card also apply to ICSC 0787 (dieldrin).
