Commercial kitchen fires such as burning oils and grease
Fire Classifications
Ordinary combustibles (wood, paper, cloth, rubber, plastics, etc.)
Flammable liquids
Live electrical current is present
Certain combustible metals (aluminum, magnesium, sodium, etc.)
Causes
Fires in workplaces start for many different reasons. Some of the most common causes of workplace fires are:
Electrical equipment
Hot work
Smoking
Cooking appliances
Heating appliances,
Unsafe use and storage of flammable liquids and gases
Mechanical heat
chemical reactions
COMMON CAUSES OF FIRES IN WORKPLACES
o Flammable liquids should be stored in approved safety containers with vapor-tight, self-closing covers.
o Minimize the build-up of static electricity by bonding and grounding metal containers
o Use a ground wire from the drum to an earth ground for as long as a drum is in use
o Attach a bonding wire from the container to the drum before filling the container.
Handling Flammable Liquids
Proper set-up of drum,
container, ground and and bonding wire
One gallon of gasoline exploding has the
same energy as 81 lbs. of dynamite
Flammable Liquids Safe Set-Up
Combustible and flammable materials are removed from the work area.
Items that cannot be removed are covered with fire-retardant blankets.
The floor is swept clean.
Any wooden floor is damped down.
A suitable fire extinguisher is at hand.
A “fire-watcher” is present in the area while the work is carried out.
The work area is visited routinely after the work has finished to check the area for smoldering.
precautions for control of hot work:
Good fire prevention
Keep work areas clean and clutter free
Know hazards of chemicals you work with
Respect smoking restrictions
Dispose of combustible materials
Change oil soaked or contaminated clothing
Clean up chemical spills and oil immediately
Prevention
Good fire protection practices
Maintain and inspect all equipment routinely
Keep fire lanes open and unobstructed
Never block access to firefighting equipment
Never move equipment or alter it in any way
Protection
Essential part of workplace safety
•Forms of protection include
Detection systems
Portable extinguishers
Fixed extinguisher systems
Alarms
Trained fire brigades
•Properly trained workers take part in the fire prevention system
Protection
Alert workers to the presence of fire
•Three forms of fire detection
Heat
Smoke
Flame
•Alarms must work at all times
•Maintenance and repairs Done by qualified and designated workers
Fire Detection
Warns workers of fire
Must have distinct sound
Qualified worker must service, maintain and test
Alarm Systems
o Fire extinguishers eliminate elements of fire tetrahedron
o If tetrahedron is broken, fire will go out
o Additional cooling and water may be necessary
Fire Extinguishing
Carrying handle/operating lever
Locking pin
Pressure gauge (except for CO² extinguishers)
Discharge nozzle or horn
Instructional label
Inspection tag
FIRE EXTINGUISHER COMPONENTS
To properly extinguish a fire use the PASS method
Pull the pin
Aim at the base of the fire
Squeeze lever
Sweep back and forth
Extinguisher (how to Use)
USING THE FIRE EXTINGUISHER SQUEEZE THE TRIGGER WHILE HOLDING THE EXTINGUISHER
UPRIGHT.
ACME FIRE
EXTINGUISHER
• If you should catch on fire:
STOP - where you are
DROP - to the floor
ROLL - around on the floor
This will smother the flames, possibly saving your life.
Just remember to STOP, DROP and ROLL.
If a co-worker catches on fire, smother flames by grabbing a
blanket or rug and wrapping them up in it. That could save them
from serious burns or even death.
What to do if Someone Catches on Fire
The last one out of the room should not lock the door, just close it. Locking the door hinders the fire department's search and rescue efforts.
Proceed to the exit as outlined in the Emergency Action Plan.
NEVER, NEVER use elevators under any circumstances.
Stay low to avoid smoke and toxic gases. The best air is close to the floor, so crawl if necessary.
How to Evacuate a Burning Building
If possible, cover your mouth and nose with
a damp cloth to help you breathe.
Once in the stairwell, proceed down to the
first floor. Never go up.
Once outside the building, report to a
predetermined area so that a head count
can be taken.
How to Evacuate a Burning Building
Emergency information should be displayed in a visible location in the building for a
quick reference in case of an emergency. This information includes:
• Evacuation routes
• Evacuation guidelines
• Emergency telephone numbers
