Apartment fire safety starts with knowing your building's emergency plan and checking that your alarms work. During a fire, follow the building's procedures and the instructions of emergency responders. This guide explains what to do when you can safely leave, what to do when escape is blocked, and how to prepare before an emergency. Smoke and hot gases can move through stairwells and shafts and make escape routes impassable in a very short time — which is why knowing your plan in advance matters.
What to Do During an Apartment or High-Rise Fire
If the fire is in your own apartment, leave immediately if you can do so safely, and close the door behind you on your way out. If fire or smoke prevents you from escaping, call 911 and follow the dispatcher's instructions.
Follow your building's emergency plan and the instructions of emergency responders. When evacuation is required and your exit route is safe, leave by the stairs. If smoke or fire prevents escape, keep doors closed between you and the fire, call 911, and report your location.
| Situation | What to do |
|---|---|
| You hear the building alarm | Follow your building's posted evacuation plan. If it says evacuate, evacuate. |
| Before you open your door | Feel the door and the handle with the back of your hand. If either is hot, do not open it. |
| Door is cool and the hallway is clear | Leave by the stairs (never the elevator unless the fire department directs you), close doors behind you, and stay out once you're out. |
| You cannot safely leave — the exit route is blocked by smoke or fire | Keep doors closed between you and the fire, call 911, and report your exact location. |

If You Cannot Safely Leave: Shelter in Place
- Call 911 and give your exact address, floor, and unit number.
- Keep the door closed and seal the gaps around it with wet towels or tape to slow smoke.
- Move to a room with a window facing the street, and take your phone.
- Follow the dispatcher's instructions. If you need to signal your location, open a window slightly to place a bright cloth outside, then close it to reduce the risk of smoke being drawn into the room.
- Stay on the phone with emergency responders and keep signaling with a flashlight, phone light, or a bright cloth.
- Never use the elevators unless the fire department directs you.
- Once you are outside, stay outside — do not re-enter the building.
Know Your Building's Fire Escape Plan Before You Need It
- Read the evacuation plan posted in your building, and identify two ways out and your nearest stairwell from your unit.
- Agree on a meeting point outside, and make sure everyone in the household knows it.
- Plan for anyone who may need help evacuating — children, older adults, or people with mobility limitations. Assign a helper in advance, and never assume someone else will assist.
- If you can't evacuate on your own, tell your building manager in advance so responders can be notified.
Five Questions to Ask Your Property Manager
Your building's plan matters as much as your own. Ask these before an emergency, so you're not figuring it out in the dark:
- What should residents do when the building alarm sounds — evacuate, or wait for instructions?
- Where are both exit routes from my unit, and which stairwell is closest?
- Who maintains the smoke and CO alarms in my unit — the building, or me?
- How do residents with mobility needs register for evacuation assistance?
- What is the assembly point outside, and what is the building's emergency contact?
Check Your Apartment's Smoke and CO Alarms
Smoke alarms
Apartment residents should install smoke alarms inside each bedroom, outside each sleeping area, and on every level of the unit. Look for alarms that:
- Detect both flaming and smoldering fires (look for UL 217 certification);
- Are interconnected, so when one compatible alarm detects smoke, the other linked alarms sound too;
- Run on a 10-year sealed battery or reliable hardwiring.
A sealed battery or hardwiring does not mean a maintenance-free alarm. Hardwired alarms should have the backup power required by the model and local code, and every alarm still needs regular testing (see below).
Coverage and maintenance guidance: NFPA — Installing and maintaining smoke alarms · USFA — Smoke alarms.
Smoke Alarms Inside Your Unit vs. the Building Fire Alarm System
Smoke alarms inside your apartment and the building's fire alarm system serve different roles. Ask your property manager which devices protect your unit, what the building alarm means, and who is responsible for maintenance. Do not assume that hallway equipment replaces the smoke alarms required inside your apartment.
Carbon monoxide alarms
Many states require landlords to provide CO alarms — but "required by the building" and "working in your unit" are not the same thing. Common sources of carbon monoxide in apartments include malfunctioning fuel-burning appliances, vehicle exhaust from an attached garage, and unsafe generator use. A working CO alarm provides an important warning of dangerous CO levels. Install alarms outside each sleeping area and on every level, following the manufacturer's instructions.
CO guidance: NFPA — Carbon monoxide safety.
Placement, testing, and replacement
- Install smoke alarms according to the manufacturer's instructions and any local requirements. General guidance recommends keeping them at least 10 feet from cooking appliances. If your apartment layout makes this difficult, ask your property manager or local fire department for guidance — don't choose a location based only on sensor type.
- Install CO alarms per the manufacturer's instructions; NFPA recommends one outside each sleeping area and on every level.
- Test every alarm at least monthly using the test button.
- Replace smoke alarms 10 years from the manufacture date, or earlier if the manufacturer specifies. Replace CO and combination alarms according to the service-life and end-of-life instructions on the product label and manual.
Choosing a model
USFA recommends using both ionization and photoelectric smoke alarms, or dual-sensor smoke alarms that contain both technologies. Note the difference: a dual-sensor smoke alarm combines two smoke-sensing technologies (ionization and photoelectric), whereas a smoke and CO combination alarm detects two different hazards — smoke and carbon monoxide — and does not necessarily contain both smoke-sensing technologies. Check the specifications of the model you choose.
Sensor type does not replace correct placement, coverage, and maintenance. If you want to compare specific Siterwell models, see our smoke detectors and smoke and carbon monoxide combination alarms.
Apartment Fire-Safety Checklist
- Working smoke alarms: each bedroom, outside each sleeping area, every level.
- Working CO alarm: outside each sleeping area and on every level.
- Test every alarm monthly (button test); replace smoke alarms 10 years from manufacture.
- Two ways out: know and walk your stairwells once so they're familiar.
- A flashlight and your phone by the bed.
- Compatible interconnected alarms: when one sounds, the other linked alarms sound too.
Frequently Asked Questions
Do apartments have carbon monoxide detectors?
In many states, landlords are required to install them, but you should confirm yours is present and working. If your building does not provide one, install a plug-in or battery CO alarm yourself.
Where should a smoke detector go in an apartment?
Inside each bedroom, outside each sleeping area, and on every level — following the manufacturer's instructions and keeping it at least 10 feet from cooking appliances.
Can I silence a smoke alarm in my apartment?
Do not attempt to silence the building's fire alarm system. For a smoke alarm inside your apartment, use the hush feature only after confirming there is no fire or suspected CO emergency, and follow the model's instructions. Never remove the battery or disable the alarm. (See our guide to stopping false alarms.)
Should I take the stairs during a high-rise fire?
Yes — use the stairs, never the elevator unless the fire department directs you, and only if the stairwell is clear of smoke.
The Bottom Line
You can't control when a fire starts, but you can control how ready your apartment is. Working alarms, a practiced escape plan, and familiarity with your building's procedures can help you respond more effectively during a fire.
