DIRECT FIRE HAZARD: Highly flammable liquid and vapour. Gas/vapour flammable with air within explosion limits. INDIRECT FIRE HAZARD: May be ignited by sparks. Gas/vapour spreads at floor level: ignition hazard. Reactions involving a fire hazard: see "Reactivity Hazard". DIRECT EXPLOSION HAZARD: Gas/vapour explosive with air within explosion limits. INDIRECT EXPLOSION HAZARD: may be ignited by sparks. Reactions with explosion hazards: see "Reactivity Hazard".

Cool tanks/drums with water spray/remove them into safety. Do not move the load if exposed to heat. Dilute toxic gases with water spray. Take account of toxic/corrosive precipitation water.

Keep upwind. Mark the danger area. Consider evacuation. Seal off low-lying areas. Close doors and windows of adjacent premises. Stop engines and no smoking. No naked flames or sparks. Spark- and explosionproof appliances and lighting equipment. Keep containers closed. Wash contaminated clothes.

Large spills/in enclosed spaces: compressed air apparatus. Large spills/in enclosed spaces: gas-tight suit.

Prevent spreading in sewers.

Take up liquid spill into a non combustible material e.g.: dry sand/earth/vermiculite or kieselguhr. Scoop absorbed substance into closing containers. Carefully collect the spill/leftovers. Damaged/cooled tanks must be emptied. Do not use compressed air for pumping over spills. Clean contaminated surfaces with an excess of water. Take collected spill to manufacturer/competent authority. Wash clothing and equipment after handling.

Materials: dry sand/earth/vermiculite or kieselguhr

Use spark-/explosionproof appliances and lighting system. Take precautions against electrostatic charges. Keep away from naked flames/heat. Keep away from ignition sources/sparks. Measure the concentration in the air regularly. Work under local exhaust/ventilation. Comply with the legal requirements. Remove contaminated clothing immediately. Clean contaminated clothing. Handle uncleaned empty containers as full ones. Thoroughly clean/dry the installation before use. Do not discharge the waste into the drain. Do not use compressed air for pumping over. Keep container tightly closed.

Store in a dry area. Store in a dark area. Under a shelter/in the open. Detached building. Store only in a limited quantity. May be stored under nitrogen. May be stored under argon. Meet the legal requirements.

Observe strict hygiene.

Keep away from naked flames/heat. Keep away from ignition sources/sparks.

Gloves. Materials for protective clothing: GIVE EXCELLENT RESISTANCE: polyethylene/ethylenevinylalcohol. GIVE GOOD RESISTANCE: neoprene. nitrile rubber. PVC. GIVE LESS RESISTANCE: butyl rubber. polyethylene. GIVE POOR RESISTANCE: natural rubber. neoprene. nitrile rubber. PVA. PVC. viton

Safety glasses

Full face mask with filter type A at conc. in air > exposure limit. Self-contained breathing apparatus if conc. in air > 250 ppm

Head/neck protection. Protective clothing

Stable under normal conditions.

Violent exothermic reaction with (strong) oxidizers: (increased) risk of fire/explosion. Reacts violently with many compounds e.g.: with (some) acids.
