TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Powder, water spray, foam, carbon dioxide.
EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE!

•INHALATION Cough. Sore throat.
Ventilation (not if powder), local exhaust, or breathing protection.
Fresh air, rest.
•SKIN Redness. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
•EYES Redness. Pain.
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 Abdominal pain. Nausea. Vomiting.
Do not eat, drink, or smoke during work.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (Extra personal protection: P2 filter respirator for harmful particles).
Separated from acids. Keep in the dark.

ICSC: 0937 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

PHYSICAL STATE; APPEARANCE:
YELLOW CRYSTALS. TURNS DEEP GREEN ON EXPOSURE TO LIGHT.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating, on contact with acids, producing toxic and irritating fumes including nitrogen oxides and sulfur oxides.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 5 mg/m3 (as TWA) (skin) (ACGIH 1996).
OSHA PEL†: none
NIOSH REL: TWA 5 mg/m3 skin
NIOSH IDLH: N.D. See: IDLH INDEX


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:
The substance irritates the eyes , the skin and the respiratory tract .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization as well as photosensitization.

PHYSICAL
PROPERTIES

Boiling point (decomposes): 371°C
Melting point: 185.1°C
Solubility in water: none
Octanol/water partition coefficient as log Pow: 4.2
