First-aid measures
SEEK MEDICAL ATTENTION IMMEDIATELY IF ANY SYMPTOMS OF POISONING ARISE.
CONTINUE MEDICAL OBSERVATION FOR AT LEAST 48 HOURS.
REMOVE SUBJECT FROM ANY EXPOSURE SOURCE.
After inhalation: Remove subject from exposure area to fresh air. Administer oxygen or artificial respiration in severe cases.
After skin contact: Remove all contaminated clothing. Wash exposed area with non abrasive soap and water.
After eye contact: Flush open eyes immediately with plenty of water.
After ingestion: If conscious, first try to induce vomiting and then give copious quantities of water. Do not give anything by mouth to an unconscious person. Get medical help immediately.
Fire-fighting measures
Extinguishing media:
Suitable: Dry chemicals, carbon dioxide, sand, foam, steam or water fog.
Not Suitable: Water jet (may spread fire).
Special hazards caused by the material, its products of combustion or resulting gases:
Incomplete combustion in a fire may result in a release of toxic carbon monoxide.
Protective equipment:
Full-body protective clothing, including breathing apparatus.
Accidental release measures
Personal precautions:
Wear full-body, industrial-type work clothing, including chemical resistant gloves, boots and goggles.
Avoid breathing vapours/dust or contact with skin and eyes. Ventilate the area if the spill occurs indoors.
Keep away from ignition sources
Environmental precautions:
Keep away from drains, surface- and ground-water and soil. Avoid any dusting.
Cleaning up methods:
Vacuum or sweep up and place in containers for safe disposal. Containers should be sealed and labelled.
Dispose of contaminated material and waste accordingwith local authority and national legislation. Dispose of as Toxic and Hazardous Waste (Directive 78 / 319 / EC).
Ensure adequate ventilation.
Handling and storage
Handling:
Ensure adequate ventilation and keep away from ignition sources and static electricity.
Prevent formation of dust. Dust can combine with air to form an explosive mixture.
Use chemical resistant gloves, safety glasses and dust mask.
Keep breathing equipment ready.
Storage:
Keep away from open fire, ignition sources or strong oxidizing substances. Guard against static electricity.
If solid, use adequate ventilation especially on the floor level.
If molten, store at 90-100 °C.

Exposure controls / personal protection
TRAIN WORKERS AND USERS IN SAFETY MEASURES
Additional information about design of technical facilities:
General or local exhaust ventilation may be necessary
General protective and hygienic measures:
Keep away from foodstuffs, beverages and feed.
Wash hands before breaks and toilet visits.
Avoid contact with eyes and skin.
Do not drink, eat, smoke or sniff while working.
Shower or take a bath at the end of work. Steam baths are recommended.
Respiratory protection:
Breathing protection is recommended (filter ABEK)
Protection of hands:
Impermeable and chemical resistant gloves (heat resistant gloves if molten).
Selection of the glove material on consideration of the penetration times, rates of diffusion and the degradation.
Material of gloves:
Butyl rubber, BR
Nitrile rubber, NBR
Neoprene
Penetration time of glove material:
The exact break trough time has to be found out by the manufacturer of the protective gloves and has to be observed.
Discard gloves as soon as any signs of degradation are noticed (e.g. swelling).
Eye protection:
Tightly sealed safety glasses or chemical grade goggles.
Stability and reactivity
Disposal considerations
Product:
Must be in accordance with local authority and national legislation. Dispose of as Toxic and Hazardous Waste (Directive 78 / 319 / EC).
Must not be disposed together with household garbage or strong oxidizing agents. Do not allow product to reach sewage system.
Uncleaned packaging:
Same as for product
