EXPLOSION


 
EXPOSURE
PREVENT DISPERSION OF DUST!

INHALATION Cough. Sore throat.
Local exhaust or breathing protection.
Fresh air, rest.
SKIN Redness.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
EYES Redness. Stinging.
Safety goggles 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. Wash hands before eating.
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!).
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 (extra personal protection: P2 filter respirator for harmful particles).
Separated from food and feedstuffs and incompatible materials (see Chemical Dangers). Dry. Well closed. Keep in a well-ventilated room.
Do not transport with food and feedstuffs.

PHYSICAL STATE; APPEARANCE:
ODOURLESS WHITE CRYSTALS.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic and corrosive fumes, including hydrogen bromide and nitrogen oxides. Reacts with some metals, amines and alkaline compounds.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, 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 when dispersed.

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

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization.
PHYSICAL
PROPERTIES
 Melting point: 120-122°C
Relative density (water = 1): 1.1
Solubility in water, g/100 ml at 22-25°C: 0.028		 Vapour pressure, Pa at 20°C: <0.01
Octanol/water partition coefficient as log Pow: 0.18
ENVIRONMENTAL
DATA
 The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment.
N O T E S
Bronopol, Bronosol and Onyxide 500 are trade names.
