direct the extinguishing agent at the source of the flames rather
than at the flames themselves.
Step 3: Squeeze the handle or lever to discharge the extinguishing
agent. Maintain a firm grip while squeezing to ensure a steady
flow of the agent.
Step 4: Sweep the nozzle or hose from side to side, covering the base
of the fire with the extinguishing agent. Continue sweeping
until the flames are completely extinguished. Be cautious not
to aim the extinguisher's stream directly at hot surfaces, as this
could spread burning materials.

burns, and unconsciousness. It sometimes affects the central nervous system too.
Some common electrical based risk causing factors are:
� Damaged extension cords or damaged electronic appliances
� Blocked electrical panels and heaters
� Overloaded circuits
� Loose connections
� Presence of inflammable substances near electronic equipments
� Old or poor wiring
