EXPLOSION


 
EXPOSURE
PREVENT DISPERSION OF DUST!

INHALATION Cough. Sore throat.
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
SKIN
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
EYES Redness. Pain.
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
INGESTION Sore throat.
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Sweep spilled substance into covered 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: A/P2 filter respirator for organic vapour and harmful dust).
Separated from strong oxidants, and food and feedstuffs. Keep in a well-ventilated room.
Do not transport with food and feedstuffs.
UN Hazard Class: 6.1

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

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic and corrosive fumes such as chlorine, hydrogen chloride and carbon monoxide (see ICSC # 0126, 0163, 0023). Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV not established.
MAK: 5 ppm; 40 mg/m3 (1993)


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

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes and the respiratory tract.


PHYSICAL
PROPERTIES
 Boiling point: 221°C
Melting point: 53°C
Relative density (water = 1): 1.7
Solubility in water: none
Vapour pressure, Pa at 25°C: 9		 Relative vapour density (air = 1): 6.3
