TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Above 48°C explosive vapour/air mixtures may be formed.
Above 48°C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
STRICT HYGIENE!

 •INHALATION
Ventilation.
Fresh air, rest.
 •SKIN Redness. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
 •EYES Redness.
Safety spectacles.
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.
Rinse mouth.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING

ENVIRONMENTAL
DATA
Environmental Hazard placard The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish.
N O T E S
Sensitization may occur with the oxidized substance. This can occur when the pure or diluted substance has been kept for several days. UN 2052 (Transport Emergency Card 30S2052) and UN 2319 (Transport Emergency Card 30GF1-III) with Hazard class 3, Pack group III are used in transport of this substance. Card has been partly updated in October 2005. See section Occupational Exposure Limits.
