TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames, NO sparks and NO smoking.  Use water spray, carbon dioxide, dry powder, alcohol-resistant foam, polymer foam. 
EXPLOSION      
 
EXPOSURE      
Inhalation   Avoid inhalation of dust.  Fresh air, rest. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.  Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder.  Do not transport with food and feedstuffs.

EMERGENCY RESPONSE SAFE STORAGE
  Separated from strong oxidants. Keep in a well-ventilated room. 

IMPORTANT DATA
Physical State; Appearance
PALE YELLOW OR COLOURLESS SOLID IN VARIOUS FORMS. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces irritating fumes. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation, 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 when dispersed. 

Effects of short-term exposure
Exposure to sun may enhance the irritating effect of this substance. This may result in chronic skin discoloration. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 404°C
Melting point: 151°C
Density: 1.27 g/cm³
Solubility in water, mg/l at 25°C: 0.135
Vapour pressure, Pa at ?°C: 0.08

Bioaccumulation of this chemical may occur in crustacea, fish, milk, algae and molluscs. It is strongly advised not to let the chemical enter into the environment. 

NOTES
Pyrene is one of many polycyclic aromatic hydrocarbons - standards are usually established for them as mixtures, e.g., coal tar pitch volatiles.
However, pyrene may be encountered as a laboratory chemical in its pure form.
Health effects of exposure to the substance have not been investigated adequately.
See ICSC 1415 Coal-tar pitch.
