TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION


EXPOSURE
STRICT HYGIENE!

 •INHALATION
Ventilation (not if powder), local exhaust, or breathing protection.
Refer for medical attention.
 •SKIN
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
 •EYES
Face shield or eye protection in combination with breathing protection if powder.
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. Wash hands before eating.
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Do NOT wash away into sewer. Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Personal protection: P3 filter respirator for toxic particles.
Separated from food and feedstuffs , incompatible materials . See Chemical Dangers. Keep in the dark. Keep in a well-ventilated room.
Do not transport with food and feedstuffs.
Severe marine pollutant.

PHYSICAL STATE; APPEARANCE:
 ODOURLESS, COLOURLESS CRYSTALS.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
 The substance decomposes on heating producing toxic fumes 0f nitrogen oxides . The substance is a weak base. Reacts with strong acids , strong oxidants , acid chlorides and acid anhydrides . Attacks iron, copper and aluminium.

OCCUPATIONAL EXPOSURE LIMITS:
 TLV: 0.2 mg/m³ as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2004).
MAK: (Inhalable fraction) 0.2 mg/m³;
Peak limitation category: II(8); Carcinogen category: 3B; Pregnancy risk group: C;
(DFG 2005).
OSHA PEL†: none
NIOSH REL: Ca TWA 0.2 mg/m3 See Appendix A
NIOSH IDLH: Ca N.D. See: IDLH INDEX


ROUTES OF EXPOSURE:
 The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

INHALATION RISK:
 Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
 The substance may cause effects on the thyroid .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
 The substance may have effects on the thyroid , resulting in goitrogenic effects.
