NO open flames, NO sparks, and NO smoking. Water spray, powder, carbon dioxide. EXPLOSION Above 26°C explosive vapour/air mixtures may be formed. Above 26°C use a closed system, ventilation, and explosion-proof electrical equipment. EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Cough. Avoid inhalation of dust. Fresh air, rest.  •SKIN Protective gloves. Rinse skin with plenty of water or shower.  •EYES Redness. Pain. Safety goggles Rinse with plenty of water (remove contact lenses if easily possible).  •INGESTION Do not eat, drink, or smoke during work. Rinse mouth. Give one or two glasses of water to drink. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into containers. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment. Provision to contain effluent from fire extinguishing. Store in an area without drain or sewer access. Fireproof.

International Chemical Safety Cards CAMPHENE ICSC: 1704 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS SOLID IN VARIOUS FORMS , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: INHALATION RISK: A nuisance-causing concentration of airborne particles can be reached quickly when dispersed, especially if powdered. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 156-160°C Melting point: 46°C Density: 0.87 g/cm³ Solubility in water, g/100 ml at 20°C: 0.0004 (very poor) Vapour pressure, kPa at 20°C: 0.4 Relative vapour density (air = 1): 4.7 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.01 Flash point: 26°C c.c. Auto-ignition temperature: 265°C Octanol/water partition coefficient as log Pow: 4.1 calculated Viscosity, mm2/s at 50 °C: 1.84 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish. It is strongly advised that this substance does not enter the environment. N O T E S Explosive limits are unknown in literature, although the substance is combustible and has a flash point < 61°C.
