Risk of serious damage if inhaled into lungs, (caused e.g by vomiting), seek medical advice urgently.

If swallowed, rinse mouth with water (only if the person is conscious)

Protective equipment for first-aiders

if exposure is likely to exceed the occupational exposure limit, in a ventilated space, use an approved respiratory protective equipment; in confined space, use a autonomous breathing apparatus.

Indication of any  medical attention       no information available

Fire-fighting measures

Technical measures

call the safety and environment service immediately.

evacuate non-essential personnel

use fine spray or fog to control fire by preventing its spread and absorbing some of its heat.

keep tankage cool by continuous spraying with water (for non cryogenic storage).

Extinguishing media       

Suitable

for minor fires : carbon dioxide (CO2) or powder

for more extensive fires : foam. water spray (mist) to cool the surfaces exposed to the fire.

Not to be used

do not use water jets (stick jets) for extinguishing fire since they could help to spread the flames

Special peril

complete combustion, with an excess of oxygen forms: carbon dioxide (CO2), water vapour , NOx.

partial combustion forms also: carbon monoxide (CO), soot and cracked products: aldehydes, ketones , carbon , polycyclic aromatic hydrocarbons (PCA or PAH) , etc...

Special exposure hazards

the vapour is heavier than air and explosive mixtures can accumulate in low spots: it may be ignited at some distance away from the spill resulting in flashbacks.

fire may cause pressure rise with risk of bursting and subsequent explosion

spreading of fire- and explosion hazard by liquid layers on the water surface

Protective equipment for firefighters

wear suitable breathing equipment, in case of risk of exposure to vapour or fumes.

protective clothing, goggles and self-contained breathing equipment should be made available for firemen.
