Guidance on Safe Use
Administrative data
First-aid measures
General advice:
Immediately remove contaminated clothing. Avoid contact with the skin, eyes and clothing.
If inhaled:
Keep patient calm, remove to fresh air, seek medical attention.
On skin contact:
Wash thoroughly with soap and water. Burns caused by molten material require hospital treatment.
On contact with eyes:
Immediately wash affected eyes for at least 15 minutes under running water with eyelids held open,
consult an eye specialist.
On ingestion:
Rinse mouth immediately and then drink 200-300 ml of water, seek medical attention.
Fire-fighting measures
Suitable extinguishing media:
foam, carbon dioxide, water spray
Specific hazards:
hydrogen cyanide, nitrogen oxides
The substances/groups of substances mentioned can be released in case of fire.
Further information:
Collect contaminated extinguishing water separately, do not allow to reach sewage or effluent
systems.
Accidental release measures
Personal precautions:
Ensure adequate ventilation. Avoid contact with skin and eyes. Use breathing apparatus if exposed to vapours/dust/aerosol.
Environmental precautions:
Do not empty into drains. Retain and dispose of contaminated wash water.
Methods for cleaning up or taking up:
For large amounts: Allow to solidify and sweep/shovel up.
For residues: Rinse away with water.
Handling and storage
Handling
Ensure thorough ventilation of stores and work areas. Avoid contact with skin and eyes. Wear suitable protective clothing and eye/face protection. Handle in accordance with good industrial hygiene and safety practice.
During transportation in silo trucks the product
is covered with nitrogen, do not climb in.
Protection against fire and explosion:
Vapours may form explosive mixture with air. Dust can form an explosive mixture with air.Take precautionary measures against static
discharges.
Storage
Segregate from acids and bases. Segregate from oxidants.
Suitable materials for containers: Stainless steel 1.4301 (V2), Stainless steel 1.4401
glass, tinned carbon steel (Tinplate), Carbon steel (Iron)
Further information on storage conditions: Keep under nitrogen.
Storage stability:
Storage temperature for liquid melt: 75 - 90 °C
The stated storage temperature should be noted.
Tablets: Store in unopened original containers in a cool and dry place.

Respiratory protection:
Respiratory protection in case of vapour/aerosol release. Gas filter for gases/vapours of organic compounds (boiling point >65 °C, e. g. EN 14387 Type A)
Hand protection:
Chemical resistant protective gloves (EN 374)
Suitable materials also with prolonged, direct contact (Recommended: Protective index 6, corresponding > 480 minutes of permeation time
according to EN 374):
butyl rubber (butyl) - 0.7 mm coating thickness
nitrile rubber (NBR) - 0.4 mm coating thickness
Manufacturer's directions for use should be observed because of great diversity of types.
Eye protection:
Tightly fitting safety goggles (splash goggles) (e.g. EN 166)
Body protection:
Body protection must be chosen depending on activity and possible exposure, e.g. apron, protecting boots, chemical-protection suit (according to EN 14605 in case of splashes or EN ISO 13982 in case of dust).
General safety and hygiene measures
Handle in accordance with good industrial hygiene and safety practice. Take off immediately all contaminated clothing. At the end of the shift the skin should be cleaned and skin-care agents applied.
