HOW TO USE FIRE EXTINGUISHERS? fire evacuation procedures in the workplace emergency evacuation, fire handling
PÂ Â AÂ Â SÂ Â S
TYPES OF EXTINGUISHERS:
Pressurized Water (P/W)- These are ordinarily found in residence halls wherever material, wood, and paper are the foremost common hazard. they are metallic colored and hold more or less a pair of 2½ gallons of water. they are capable of discharging a distance of 25 – 30 meters for roughly 1.0 -1.5 minutes.
Dry Chemical (ABC) or (BC) – These are ordinarily found in cars, laboratories, and alternative places wherever gas, oil, and alternative combustible/flammable liquids are used. {they are they're} typically red in color and are capable of spraying 10 – 15 Meters for roughly 30 - 35 seconds.
Carbon Dioxide (CO2) – These are ordinarily found solely in electrical or mechanical rooms/offices wherever electricity is the hazard. they're accustomed to placing out electrical fires whereas the instrumentality remains energized. The carbonic acid gas extinguishers are red in color, don't have any gauge-to-point quantity of contents, and are restricted to a twig distance of 5 –10 meters for regarding 10 - 12 seconds.
Halon - These extinguishers were used for fire area fires in the past, however, their use now's questionable due to health risks related to the organic compound agents during a fireplace scenario.
CRITICAL POINTS TO BE REMEMBERED AT THE TIME OF FIRE (IF REQUIRED)

Carbon monoxide (CO) Molar MassÂ
The molar mass of carbon monoxide (CO) is 28.01 grams per mole.Â
To calculate the molar mass of CO, add the atomic masses of each element in the molecule.
Carbon (C): 1 atom x 12.01 g/mol = 12.01 g/mol Oxygen (O): 1 atom x 15.99 g/mol = 15.99 g/mol
Total molar mass of CO = 12.01 g/mol + 15.99 g/mol = 28.01 g/mÂ
The molar mass of carbon monoxide is about 28.01 grams per mole.
