20. FIRE BLANKET Fire blanket – a firefighting equipment used to extinguish a fire in the bud by cutting off the air flow from the material in flames. Made of fibreglass, has the area of about 2-3m 2 Firefighting equipment
21. Using the blanket means tightly covering the object on fire e.g. a frying pan, a barrel with burning liquid.

22. ‘ Buildings should be equipped with portable or mobile extinguishers which meet the requirements of Polish Norms and which are designed to extinguish such fires as may break out in a particular building.’ EQUIPPING WITH FIRE-FIGHTING EQUIPMENT Firefighting equipment
23.
24. Mark the location of the equipment in accordance with PN. In multi-storey buildings, the equipment should be located in the same places on each story, if con s tructional conditions permit. The equipment should be located in places not at risk of mechanical damage or operation of heat sources (ovens, furnaces or heaters). Firefighting equipment RULES FOR PLACING FIRE EXTINGUISHERS
