TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Not combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION (See Ingestion).
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN MAY BE ABSORBED! (See Ingestion).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
•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 Dizziness. Weakness. Headache. Nausea. Vomiting. Convulsions.
Do not eat, drink, or smoke during work. Wash hands before eating.
Give a slurry of activated charcoal in water to drink. Rest. 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. Do NOT let this chemical enter the environment. (Extra personal protection: chemical protection suit including self-contained breathing apparatus).
Separated from food and feedstuffs . Well closed. Keep in a well-ventilated room. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing.
Do not transport with food and feedstuffs.
Severe
marine pollutant.

PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS .

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating above 245°C, producing hydrogen chloride , phosgene .

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 mg/m3 as TWA; (skin); A4 (not classifiable as a human carcinogen); (ACGIH 2008).
MAK: 0.1 mg/m3 (Inhalable fraction);
Peak limitation category: II(8);
skin absorption (H);
Pregnancy risk group: C;
(DFG 2008).
OSHA PEL: TWA 0.1 mg/m3 skin
NIOSH REL: TWA 0.1 mg/m3 skin
NIOSH IDLH: 2 mg/m3 See: 72208


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 on spraying or when dispersed, especially if powdered.

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

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Decomposes below boiling point at 245°C
Melting point: 200°C
Density: 1.7
g/cm3
Solubility in water, g/100 ml at 25°C:
none
Vapour pressure, Pa at 25°C: negligible
Octanol/water partition coefficient as log Pow: 5.34

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to honey bees , birds and mammals . It is strongly advised not to let the chemical enter into the environment because it persists in the environment. In the food chain important to humans, bioaccumulation takes place, specifically in fish and seafood . Avoid release to the environment in circumstances different to normal use.

N O T E S

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.
Transport Emergency Card: TEC (R)-61G41a

NFPA Code: H3; F0; R; 0
Card has been partially updated in November 2008: see Occupational Exposure Limits, Storage.
