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.
Water spray, carbon dioxide, dry powder, alcohol-resistant foam, or 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.
Safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion
Do not eat, drink, or smoke during work.
Do NOT induce vomiting. Give plenty of water to drink. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder. Do NOT let this chemical enter the environment. (Extra personal protection: P2 filter respirator for harmful particles.)
Do not transport with food and feedstuffs.

PYRENE ICSC: 1474
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
PALE YELLOW OR COLOURLESS SOLID IN VARIOUS FORMS

CHEMICAL DANGERS:
The substance decomposes on heating producing irritating fumes.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established. MAK 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 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

EFFECTS OF SHORT-TERM EXPOSURE:
Exposure to sun may provoke an irritating effect of pyrene on skin and lead to chronic skin discoloration.

PHYSICAL PROPERTIES
Boiling point: 404C
Melting point: 151C
Density: 1.27 g/cm
Solubility in water: 0.135 mg/l at 25C
Vapour pressure, Pa at C: 0.08
Octanol/water partition coefficient as log Pow: 4.88
ENVIRONMENTAL DATA
Bioaccumulation of this chemical may occur in crustacea, in fish, in milk, in algae and in molluscs. It is strongly advised that this substance does not enter 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.
