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
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Dullness. Headache.
Closed system and ventilation.
Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
•SKIN
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
•EYES Redness.
Safety goggles, 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
Do not eat, drink, or smoke during work.
Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS SOLID IN VARIOUS FORMS , WITH CHARACTERISTIC ODOUR. TURNS PURPLE ON EXPOSURE TO AIR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
On combustion, forms toxic gases. The solution in water is a weak base. Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: A1 (skin) (ACGIH 1996).
MAK: skin absorption (H);
Carcinogen category: 1
(DFG 2006).
OSHA PEL: 1910.1011 See Appendix B
NIOSH REL: Ca See Appendix A
NIOSH IDLH: Ca 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 by dispersing.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes. The substance may cause effects on the bladder , resulting in blood in urine.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
This substance is carcinogenic to humans.
