TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible. Liquid formulations containing organic solvents may be flammable.
NO open flames.
Powder . Foam. Carbon dioxide.
EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Abdominal cramps. Convulsions. Dizziness. Sweating. Nausea. Unconsciousness. Pupillary constriction, muscle cramp, excessive salivation. Symptoms may be delayed (see Notes).
Local exhaust or breathing protection.
Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
•SKIN MAY BE ABSORBED! (See Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
•EYES (Further see inhalation.)
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 (See Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
On combustion, forms toxic and corrosive gases.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (inhalable fraction and vapour) 0.05 mg/m3 as TWA (skin); A4 (not classifiable as a human carcinogen); BEI issued. (ACGIH 2007).
OSHA PEL†: none
NIOSH REL: TWA 0.1 mg/m3 skin
NIOSH IDLH: N.D. See: IDLH INDEX


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and 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 on spraying or when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the nervous system , resulting in convulsions and respiratory failure. Cholinesterase inhibitor. Exposure may result in death. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Melting point: 49.2°C
Density: 1.15
Solubility in water, g/100 ml: 0.03
Vapour pressure, Pa at 30°C: <1
Octanol/water partition coefficient as log Pow: 3.3

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms. Avoid release to the environment in circumstances different to normal use.

N O T E S

Depending on the degree of exposure, periodic medical examination is indicated. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s). Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home. Bayer 68138, Bay SRA 3886, ENT 27572, Nemacur, Nemacur P, and NSC 195106 are trade names.
