Appropriate engineering controls
General room ventilation is adequate for storage and handling.
Perform filling operations only at stations with exhaust ventilation facilities.
Individual protection measures, such as personal protective equipment
Respiratory protection : In case of insufficient ventilation, wear suitable respiratory
equipment.
Wear a positive-pressure supplied-air respirator.
Vapours are heavier than air and can cause suffocation by
reducing oxygen available for breathing.
For rescue and maintenance work in storage tanks use self-
contained breathing apparatus.
Hand protection : Leather gloves
In case of contact through splashing:
Protective gloves
Neoprene gloves
Polyvinyl alcohol or nitrile- butyl-rubber gloves
Eye protection : Wear as appropriate:
Safety glasses with side-shields
If splashes are likely to occur, wear:
Goggles or face shield, giving complete protection to eyes
Skin and body protection : Avoid skin contact with leaking liquid (danger of frostbite).
