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.
Water in large amounts.
EXPLOSION


EXPOSURE


•INHALATION
Local exhaust.
Fresh air, rest.
•SKIN Redness.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
•EYES
Safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION Abdominal pain. Drowsiness. Nausea.
Do not eat, drink, or smoke during work.
Rinse mouth. Give one or two glasses of water to drink.

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.
Dry. Well closed. Keep in a well-ventilated room.

ICSC: 0446 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:
CRYSTALS.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes including sulfur oxides, nitrogen oxides and sodium oxide. The substance is a weak base.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: 2 mg/m3 (Inhalable fraction); sensitization of skin (Sh);
Peak limitation category: II(2) Pregnancy risk group: D. See Notes
(DFG 2008).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by ingestion.

INHALATION RISK:
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the skin.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Melting point: 90-102°C
Relative density (water = 1): 1.1
Relative vapour density (air = 1): 5.9

ENVIRONMENTAL
DATA


N O T E S

Health effects of exposure to the substance have been investigated, but none has been found. The reaction with nitrosating agents can result in the formation of carcinogenic N-nitrosodiethylamine (DFG 2008). Imuthiol is a trade name.
Card has been partially updated in July 2007: see Occupational Exposure Limits, Ingestion First Aid.
