⚡ Understanding Smoke Alarms & Fire Extinguishers

Smoke alarms provide an early warning that can give you time to escape a fire. Fire extinguishers may help control a small, contained fire, but escaping safely is always more important than protecting property.

You may have less than two minutes to escape after a smoke alarm sounds. Make sure everyone in the home knows what the alarms sound like and what to do.

Where to Install Smoke Alarms

Install smoke alarms:

Inside every bedroom
Outside every sleeping area
On every level of the home
In the basement
Near stairways when recommended
In locations specified by the manufacturer and local fire code

Install alarms on the ceiling or high on a wall according to the manufacturer’s directions.

Interconnected alarms provide additional protection. When one detects smoke, every connected alarm sounds.

The U.S. Fire Administration recommends installing alarms inside and outside each sleeping area and on every level of the home. U.S. Fire Administration

Maintain Every Smoke Alarm

Test alarms once a month.
Replace removable batteries at least once a year or when the alarm begins chirping.
Do not replace batteries in a sealed ten-year alarm.
Replace the entire alarm every ten years unless its instructions require earlier replacement.
Replace an alarm that does not respond during testing.
Keep alarms free of dust and paint.
Follow the manufacturer’s cleaning instructions.
Check the manufacture or replacement date on every alarm.

Hardwired alarms usually contain backup batteries. They still require testing and maintenance.

Never remove an alarm’s battery because it activates during cooking. Use the hush button, improve ventilation, or ask a qualified professional whether the alarm should be relocated.

Make Sure Everyone Can Hear the Alarm

Standard alarms may not wake or alert everyone.

Additional equipment may be needed for people who:

Are deaf or hard of hearing
Sleep deeply
Take sedating medication
Have difficulty understanding alarms
Need physical help evacuating

Available alerting devices may use:

Flashing lights
Bed or pillow shakers
Lower-frequency sounds
Voice alerts
Connected phone notifications

Include assistance in the household escape plan. Do not assume that children, older adults, or people with disabilities will be able to evacuate without help.

What to Do When a Smoke Alarm Sounds

Treat every alarm as a real emergency until you know otherwise.

Leave immediately.
Alert other household members.
Stay low if smoke is present.
Feel a closed door with the back of your hand before opening it.
Use another exit if the door or handle feels hot.
Close doors behind you when possible.
Go to the household meeting place.
Call 911 from outside.
Stay outside.

Never return inside for belongings, medication, or pets. Tell firefighters if someone or a pet may still be inside.

Choose the Right Fire Extinguisher

Extinguishers are rated for different types of fire:

Class A: Wood, paper, cloth, and similar materials
Class B: Flammable liquids
Class C: Energized electrical equipment
Class D: Combustible metals
Class K: Cooking oils and fats, usually in commercial kitchens

A multipurpose extinguisher labeled ABC is commonly used for several types of household fires.

Choose an extinguisher that:

Is appropriate for the expected fire
Has a recognized testing laboratory’s certification
Is large enough to be useful
Is light enough for you to operate
Has clear instructions
Can be reached without moving toward a fire

Ask your local fire department which type and size are appropriate for your home.

Where to Keep Fire Extinguishers

Place extinguishers:

Near an exit
Where they are visible
Where they are easy to reach
Away from the most likely source of fire
At the height recommended by the manufacturer
Where children cannot play with them

Do not place an extinguisher directly beside a stove or furnace. A fire could prevent you from reaching it.

Everyone old enough to use an extinguisher should know where it is located before an emergency occurs.

Use an Extinguisher Only When It Is Safe

Attempt to use an extinguisher only when:

Someone has called 911.
Everyone else is leaving.
The fire is small and contained.
Smoke is not overwhelming the room.
You have the correct extinguisher.
You know how to use it.
You are physically able to operate it.
You have a clear exit behind you.
The fire is not spreading rapidly.

If you are uncertain, leave immediately and call 911.

The U.S. Fire Administration recommends using an extinguisher only on a small, contained fire when you are safe from toxic smoke and have a clear escape route. U.S. Fire Administration

Remember PASS

To operate many common extinguishers:

Pull the pin.
Aim low at the base of the fire.
Squeeze the handle slowly and evenly.
Sweep the nozzle from side to side.

Keep the exit behind you while using the extinguisher.

Leave immediately if:

The extinguisher empties
The fire does not go out quickly
Flames begin spreading
Smoke becomes thick
Heat becomes intense
Your exit may become blocked
You feel unsure or unsafe

Even if the fire appears extinguished, leave the building and let firefighters inspect the area. A fire may continue burning inside a wall, cabinet, appliance, or other hidden space.

Check Fire Extinguishers Regularly

Inspect each extinguisher according to its instructions.

Check that:

It is in its assigned location.
Nothing blocks access.
The pressure gauge is in the recommended range.
The pin and tamper seal are intact.
The hose and nozzle are clear.
The container is not rusted, dented, leaking, or damaged.
The label is readable.
It has not reached its replacement or service date.

An extinguisher that has been discharged—even briefly—may need to be recharged or replaced.

Some extinguishers require professional maintenance. Follow the label and local fire-code requirements.

Never Use Water on Certain Fires

Do not throw water on:

A grease or cooking-oil fire
An energized electrical fire
A fire involving flammable liquid
A combustible-metal fire

Water can spread burning grease and may create an electrical-shock hazard.

If a small pan fire occurs and you can do so safely:

Turn off the heat.
Slide a lid over the pan.
Leave the lid in place.
Do not move the pan.
Call 911 if the fire does not go out immediately.

Never carry a burning pan outside.

Create a Home Escape Plan

Every household should have:

Two possible exits from each room
A meeting place outside
A plan for children
A plan for older adults and people with disabilities
A plan for pets
A way to call 911
Practice drills at least twice a year

Make sure doors and windows can be opened. Keep hallways and exits free of clutter.

An extinguisher is not a substitute for working smoke alarms or an escape plan.
