Common name(s) / synonym(s) : BENZENE , Bicarburet of hydrogen, carbon oil, coal naphtha, cyclohexatriene, mineral naphtha, phenyl hydride, pyrobenzol CAS number / EC number : 71-43-2 /601-020-00-8. 4. First-Aid Measures Eye: Irrigate immediately. If this chemical contacts the eyes, immediately wash (irrigate) the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately. Skin: Soap wash immediately. If this chemical contacts the skin, immediately wash the contaminated skin with soap and water. If this chemical penetrates the clothing, immediately remove the clothing, wash the skin with soap and water, and get medical attention promptly.

7 Breathing: Respiratory support. If a person breathes large amounts of this chemical, move the exposed person to fresh air at once. If breathing has stopped, perform artificial resuscitation. Keep the affected person warm and at rest. Get medical attention as soon as possible. Swallow: Medical attention immediately. If this chemical has been swallowed, get medical attention immediately. Do not induce vomiting. Keep at rest. 5. Fire-Fighting Measures Extinguishing media: Water spray, foam or dry chemical based on situation. Small Fires Dry chemical, CO2, water spray or regular foam. Large Fires Water spray, fog or regular foam. Do not use straight streams. Move containers from fire area if you can do it without risk.

8 Fire involving Tanks or Car/Trailer Loads Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting SAFETY devices or discoloration of tank. Always stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; if impossible, withdraw from area and let fire burn. Specific hazards arising from the chemical: This is a Flammable Liquid and may release vapours that form flammable mixtures at or above the flash point. BENZENE SDS. Page 3 of 11. Revised 2 on 11/2/2015. Special protective equipment and precautions for fire fighters: Use water spray to cool fire exposed surfaces and to protect personnel.

9 Shut off fuel to fire if possible to do so without hazard. If a leak or spill has not ignited use water spray to disperse the vapours. Either allow fire to burn out under controlled conditions or extinguish with foam or dry chemical. Try to cover liquid spills with foam. A self-contained breathing apparatus (SCBA) is recommended for indoor fires and any significant outdoor fires. For small outdoor fires, which may easily be extinguished with a portable fire extinguisher, use of an SCBA is optional. Caution: All these products have a very low flash point: Use of water spray when fighting fire may be inefficient. 6. Accidental Release Measures Call Emergency Response Telephone Number on Shipping Paper first.

10 If Shipping Paper not available or no answer, refer to appropriate telephone number. As an immediate precautionary measure, isolate spill or leak area for at least 50 meters (150 feet). in all directions. Keep unauthorized personnel away. Stay upwind. Keep out of low areas. Ventilate closed spaces before entering. Remove all ignition sources. Dike far ahead of liquid spill for later disposal. Water spray may reduce vapor; but may not prevent ignition in closed spaces. Warn occupants and shipping in downwind areas of fire and explosion hazard and request all to stay clear. Collect leaking and spilled liquid in sealable containers as far as possible. Prevent additional discharge of material, if possible to do so without hazard.
