Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Foam, powder, carbon dioxide, water in large amounts . EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Cough. Abdominal cramps. Dizziness. Headache. Confusion. Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Redness. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower.  •EYES Redness. Pain. Face shield or eye protection in combination with breathing protection. Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention.  •INGESTION Nausea. Vomiting. Abdominal pain. Diarrhoea. Do not eat, drink, or smoke during work. Rinse mouth. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Let solidify if molten. Personal protection: particulate filter adapted to the airborne concentration of the substance. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Separated from strong oxidants. Dry. Xn symbol R: 20/22-36/37/38 S: (2) Signal: Warning Excl mark Harmful if swallowed Causes skin irritation Causes eye irritation May cause drowsiness or dizziness SEE IMPORTANT INFORMATION ON BACK ICSC: 0118 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994.

International Chemical Safety Cards CAPROLACTAM ICSC: 0118 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE, HYGROSCOPIC FLAKES OR CRYSTALS. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating producing toxic fumes including nitrogen oxides , ammonia . Reacts violently with strong oxidants to produce OCCUPATIONAL EXPOSURE LIMITS: TLV: (as inhalable fraction and vapor) 5 mg/m³ as TWA; A5 (not suspected as a human carcinogen); (ACGIH 2009). MAK: as vapour and dust (Inhalable fraction) 5 mg/m³; Peak limitation category: I(2); Pregnancy risk group: C; (DFG 2009). OSHA PEL†: none NIOSH REL: Dust: TWA 1 mg/m3 ST 3 mg/m3 Vapor: TWA 0.22 ppm (1 mg/m3) ST 0.66 ppm (3 mg/m3) NIOSH IDLH: N.D. See: IDLH INDEX ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol. INHALATION RISK: A harmful concentration of airborne particles can be reached quickly when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the skin , the eyes and the respiratory tract . The substance may cause effects on the central nervous system. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the nervous system and liver . PHYSICAL PROPERTIES Boiling point: 267°C Melting point: 70°C Relative density (water = 1): 1.02 Solubility in water: good Vapour pressure, Pa at 25°C: 0.26 Relative vapour density (air = 1): 3.91 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.0 Flash point: 125°C o.c. Auto-ignition temperature: 375°C Explosive limits, vol% in air: 1.4-8 Octanol/water partition coefficient as log Pow: -0.19 ENVIRONMENTAL DATA This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal. N O T E S The substance is usually used, stored and transported in liquefied (molten) form at about 80°C. ADDITIONAL INFORMATION ICSC: 0118 CAPROLACTAM (C) IPCS, CEC, 1994
