All vehicle fires emit hazardous gases. One component often mentioned in electric cars is hydro fluorides (HF), which occur in higher concentrations in these vehicles compared to fossil fuel cars if the battery is on fire.
Hydro fluorides bind easily to water, this means the drencher system or any other source of water such as a fire hose or boundary cooling device, washes out large parts of HF gases.
Remember:
Firesuits should be worn in accordance with the instructions. This will protect well from all vehicle fire gases including those of lithium-ion batteries, such as hydro fluoride. When possible, dress with an assistant.
Having the trousers rolled down over boots makes it quick and easy to put both on.
Make sure that the hood is smoothed down over your shoulders and chest.
Both the coat zip and the hook and loop fastening should be secured all the way up to the throat and the collar strap fastened.
The assistant should take the weight of the breathing set whilst you put your arms through the straps.
The air cylinder valve should be open, but you should breathe outside air and not from the cylinder.
When fastening the face mask straps, begin with the two near your chin. Pull them at the same time to avoid the mask twisting on your face. Tighten the remaining straps in a similar manner.
Take two or three breaths from the cylinder to check air flow is OK and that the mask is well sealed.
Leave the cylinder valve open but return to breathing outside air until all team members are properly dressed and you are all ready to begin firefighting operations. Only then begin to breathe from the cylinder.
Lastly, put on your helmet and gloves.
A final check should be made by the assistant or teammates to check that no bare skin is left exposed including the face, neck, throat and wrists.
The mask's neck strap must go directly against the skin of your neck, not over the hood or coat collar.
After bringing your hood up over your head, the assistant must make sure that all the face mask straps are tucked away inside the hood.
Are you sure to perform this action?
