When using the car extinguisher, is it proper to avoid full opening of the bonnet?

In the video you are driving along a narrow road among trees behind a silver car, which stops, and smoke comes out from under its bonnet; the driver opens the door. When you put out a fire in the engine compartment with a car fire extinguisher, you avoid opening the bonnet fully - you spray through the gap of the slightly opened bonnet or through the air intake. The answer is: yes.

The Regulation on the technical conditions of vehicles requires a motor vehicle to have a fire extinguisher in an easily accessible place, and the Road Traffic Act requires every road user to avoid any action that could cause danger. A fire under the bonnet smoulders with a limited supply of oxygen; if you lift the bonnet suddenly, the flow of air may cause flames to burst out straight into your face. That is why you spray through the partly opened gap, and after the fire is out you do not open the bonnet fully, because the fire may start again. A small powder fire extinguisher lasts only a few seconds, so if you cannot put the fire out straight away, you call the fire brigade, move people away and move away yourself.

Legal basis: § 11 para. 1 point 14 of the Regulation on the technical conditions of vehicles and the scope of their necessary equipment; Art. 3 para. 1 of the Road Traffic Act (Prawo o ruchu drogowym)
