BCOT - Fire Safety exam 2023 with complete solution
in case of fire
Sound the alarm (location & how to activate)
MUST Call Main Control
Calling Main Control for Fire Procedures
Give your name
Location of fire
Type of fire
Hold phone for verification
The fire triangle
oxygen - right side
heat -bottom
fuel - left side
Fire Tetrahedron
fuel -top triangle
chemical chain reaction -bottom triangle
heat- bottom left triangle
oxygen - bottom right triangle
Chemical Chain reaction
in the burning process of fuel elements( compounds)are released by heat produced by
the fire. These elements join in the fire (combined with oxygen) to produce more heat
which releases more fuel elements
What is the difference between the fire triangle and the fire tetrahedron?
Chemical chain reaction
Oxygen percentage in normal air
21%
Oxygen
supports combustion & life
Minimum percentage of oxygen needed to support respiration & combustion
16%
visible flame goes out (oxygen)
15%
Fire goes out (oxygen)
5%
definition of fire
fire is a rapid chemical combination of fuel and oxygen in the presence of Heat usually
accompanied by production of heat light and combustion byproducts (smoke gases and
dust)
byproducts of combustion
smoke gases and dust
Fire is usually accompanied by
smoke gases and dust
solid states of fuel -tetrahedron
wood, paper, plastic, rubber
