Fire and Safety Test

How much do property losses exceed annually?

$2 billion

Fuel can include:

-Combustible solids like paper, wood, and some metals -Flammable liquids and gases

Exits should be

-Properly identified -Never to be blocked or locked (so as to stop exit) -Never block fire doors open to prevent closure

Fires will continue until one of three things occur:

1) oxygen is depleted 2)the heat is removed 3)the fuel is consumed

How can you reduce the likelihood of a fire in your workplace?

1)By being proactive and utilizing a fire protection plan 2)participating in fire safety training and 3)using caution at all times.

Common workplace causes of fires:

1)Electrical- 2)Chemical- 3)Hot works- 4)Housekeeping 5)Smoking-

Fire and smoke alarms should be

1)Installed in all areas of the building 2)Checked regularly for proper operation

PASS

1)Pull the pin 2)Aim the extinguisher at the base of the fire 3)Squeeze the trigger 4)Sweep from side to side

Only fight fire when:

1)The fire is small and contained 2)You are safe from toxic smoke 3)You have a means of scape 4)Your instincts tell you it is OK

Emergency action plan should be made available in writing if there are

11 or more employees at your workplace

What percentage of workplace fires are a result o catastrophic failure of equipment

15%

How many employers per year die in fires? and how many injured?

200 employers... 5000 injured

In the US, how many workplaces experience a serious fire?

70-80,000

What percentage of fires are a result of factors related to human behavior?

85%

How can you reduce the chances of injury or serious loss if a fire occurs?

A simple emergency plan as well as proper detection and fire extinguishers

Activate

Activate the fire alarm or contact 911

Assemble

Assemble in the predetermined location outside of the building.

Assist

Assist others in exiting the building

Attempt

Attempt to Extinguish the fire

Wet chemical extinguishers with misting nozzle allows them to be used for

B and C fires

Regular dry chemical should be used on

B, C, or K (not as much used as for Class K fires anymore with advent of wet chemical extinguishers)

Halogenated or Clean Agent can be used on

C, Class A and B fires

including gasoline, fuels, paints, solvents, and manufacturing chemicals. Hot works- welding, torching or other tasks that emit sparks.

Chemical

-Most Common and use ordinary combustibles such as wood, paper, cloth, rubber and many plastics as their fuel. -Usually the easiest to contain. -May be classified by their ability to produce ash.

Class A

Foam is used on

Class A and B fires only

multi-purpose dry chemical used on

Class A, B, and C fires

-Combustible fuel fires that involve flammable liquids, oils, greases, gases, tars, oil based liquids and alcohol. -Water should never be used on this type of fire. It will only cause the fuel to splash and possibly spread

Class B

Carbon dioxide can be used on

Class B and C fires

-Involve energized electrical wiring and equipment. Class C fires are unique because as soon as the electricity is eliminated, they become one of the other classes of fire. -Water should not be used to control this type of fire. Since water can carry a current, the risk of electrocution is highly possible.

Class C

Halogenated or Clean Agent are used mainly on

Class C fires

-Involve combustible metals like sodium, titanium, magnesium, potassium, aluminum, and lithium. -Most of these metals usually burn at higher temperatures and can react violently with water or other chemical agents -Can be controlled with dry powder extinguishing agents based on sodium chloride, other salts and also clean dry sand. Dry powder should not be confused with dry chemical. -Trying to extinguish a metal fire with water, carbon dioxide and dry chemical extinguishers will result in spreading and accelerating this type of fire

Class D

-Involves cooking and vegetable oils, grease, and fats -Considered a sub category of a class B fire, they typically burn at higher temperatures and have been given their own classification -Can be controlled with either wet or dry chemical extinguishers

Class K

Wet chemical extinguishers used on

Class K, and sometimes class A

neglect and misuse of wiring and electrical appliances, especially space heaters.

Electrical

There are different types of

Foam Extinguishers and you need to be aware of which type you are using and its proper use and limitations. Foam holds down the vapors and is mostly for professional use.

welding, torching or other tasks that emit sparks.

Hot works

accumulation of garbage in work or storage areas and improper storage of flammable substances.

Housekeeping

Fire extinguisher inspection: monthly

Is it in the correct location? Is it visible and accessible? Does the gauge indicate the correct pressure?

Contain sodium chloride salt and thermoplastic additive

Metl-X

Plastic melts to form an oxygen excluding crust over the metal, and the salt dissipates heat.

Metl-X

OSHA guidelines for an emergency action plan can be found in

OSHA 29 CFR 1910.38

Guideline for a fire protection plan are found in

OSHA 29 CFR 1910.39

discarded cigarettes or smoking in inappropriate areas

Smoking

Annualy Fire extinguisher inspection performed by who

State Fire Marshall.

Other maintenance may also need to be completed depending on the type of extinguisher and its age. (T or F)

T

They extinguish the fire by forming a soapy foam blanket over the burning oil and by cooling the oil below its ignition temperature.

Wet chemical extinguishers

Fires start with heat, which serves as

a source of ignition

4 A's

activate, assist, attempt, and assemble

All employers are required to have

an emergency action plan only when the applicable OSHA standard requires it

Water is used on

class A only

Metl-X are used on

class D fires

Fire extinguishers are only

designed to fight small fires

extinguisher will only

discharge for a few seconds

OSHA strongly recommends that all employers have an

emergency action plan

OSHA strongly recommends that all employers...

have a fire prevention plan

All fires involved a chemical reaction between 3 elements:

heat, fuel, and oxygen

Dry chemicals...

inhibit the chemical reaction of a fire

Heat can be generated by many things including:

open flames, static electricity, cutting and welding operations, faulty electrical circuits, unshielded hot surfaces, friction, chemical reactions

Halogenated or Clean Agent remove

oxygen from fires

For a complete listing of the fire prevention plan requirements...

please review the copy of the OSHA standard that accompanied this program

What does water do?

remove heat

Carbon dioxide

remove the oxygen from the fire and also remove heat with a cold discharge.

Although employers are required to have a fire prevention plan when...

the applicable OSHA standard requires it

High pressure discharge of carbon dioxide can cause

the burning materials to scatter with a Class A fire.

Carbon dioxide is ineffective on class A fires because

the fire can continue to smolder and possibly reignite

Emergency plan may be discussed verbally when

there are 10 or fewer employees

Your employer may choose to discuss this plan with you verbally if

there are 10 or fewer employees

The Fire Prevention Plan should be made available to you in writing if

there are 11 or more employees at your workplace.
