ε-Caprolactam

Remove victim to fresh air. In case of respiratory arrest immediately employ artificial respiration and get medical attention. If the injured is unconscious, lay and transport him/her in recovery position.

Symptoms: narcotising effect, headache, dizziness and nausea

Immediately remove contaminated clothing. Wash affected skin with plenty of water and soap. Cool skin burns caused by liquid product immediately with cold water, get medical attention. Do not peel off solid product from the skin, but remove using water. If irritation persists, get medical attention.

Symptoms: Possible susceptibility to eczema.

Remove contact lenses, if present. Immediately wash for at least 15 minutes under running water with the lids wide open. If available, use Previn solution. Consult a physician.

Rinse the mouth. Drink plenty of water. Avoid vomiting due to danger of aspiration. Get medical advice immediately.

Symptoms: narcotising effect, headache, dizziness and nausea

Water, CO₂, foam, powder

Vapours can form explosive mixtures with air. In case of fire, development of hazardous fire gases or vapours possible. Static charging of the flakes alone or between flakes and liquid may cause ignition of an explosive gas mixture. Product dust accumulating at the workplace may further increase the explosion risk and intensity.

Cool affected containers by means of water fog.

Avoid skin contact and inhalation of vapours. Leakages of molten caprolactam involve danger of slipping; therefore isolate place of leakage. Seal the leak as good as possible. Avoid dust formation. Do not inhale dusts. Provide ample fresh air in enclosed rooms.

Prevent the substance or contaminated firefighting water from running off into the soil, waterways or ground water.

Isolate molten caprolactam leakage, leave to solidify and take up mechanically. Flush away residual product with plenty of water.

Materials: solvent-resistant containers (steel, glass)

When handling the substance, eye and body protection must be worn. When vapours occur, wear breathing apparatus with filter A.

Hygroscopic product. Avoid contact with moisture contained in the air. Take precautions against electro-static charging, protect from overheating. Store the liquid product in heatable, heat-insulated containers at a temperature of 80 to 90 °C under inert gas (e. g. nitrogen with a maximum O₂ content of 50 ppm.)

Handle in accordance with good industrial hygiene and safety practice.

Observe explosion and fire protection regulations. Have fire extinguisher ready. There must be no sources of ignition within the protected zone.

Suitable technical control devices: See exposure scenarios in Annex.

Chemical resistant protective gloves (EN 374) Suitable material, also for prolonged direct contact (recommended: protective index 6, i. e. permeation time as per EN 374 > 480 min.): Butyl rubber (butyl) – thickness ≥ 0.7 mm Nitrile rubber (NBR) – thickness 0.4 mm

Wear frame goggles with lateral shields.

Ensure adequate ventilation if vapours/aerosols are present. Recommended filter type: FFP2.

Depending on the activities being carried out and possible exposure wear clothing that covers or protects the entire body, e. g. apron, protective boots, chemical protective overall (as per DIN EN 465).
