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 plenty of water, seek medical attention.

Fire-fighting measures

Suitable extinguishing media:
foam, carbon dioxide, water spray, water
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

Accidental release measures

Personal precautions:
Ensure adequate ventilation. 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

Ensure thorough ventilation of stores and work areas. 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. Take precautionary measures against static
Segregate from acids and bases. Segregate from oxidants.

Exposure controls / personal protection

Components with workplace control parameters
105-60-2: caprolactam

marine water: 0.2 mg/l
intermittent release: 1 mg/l
sediment (freshwater): 18.7 mg/kg
sediment (marine water): 1.87 mg/kg
soil: 2.55 mg/kg
STP: 1737 mg/l

Short-term exposure - local effects, Inhalation: 5 mg/m3Personal protective equipment
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.

Stability and reactivity

No hazardous reactions if stored and handled as prescribed/indicated.

Chemical stability
The product is stable if stored and handled as prescribed/indicated.

Possibility of hazardous reactions
Reacts with oxidizing agents. Polymerization coupled with heat formation.

Conditions to avoid
Temperature: > 100 °C
Avoid all sources of ignition: heat, sparks, open flame. Avoid formation of polymers in valves and pipes.

Incompatible materials
Substances to avoid: oxidizing agents

Hazardous decomposition products
Thermal decomposition products:
No hazardous decomposition products if stored and handled as prescribed/indicated. Incomplete combustion results in formation of toxic gases, containing mainly carbon monoxide and carbon dioxide.

Disposal considerations

Waste treatment methods
Contact manufacturer.
Incinerate in suitable incineration plant, observing local authority regulations.

Contaminated packaging:
Uncleaned empties should be disposed of in the same manner as the contents.
