Do Vapes Set Off Smoke Alarms? A Guide to cross the Invisible Clouds

Do Vapes Set Off Smoke Alarms?

Yes, they can. Indeed, some of them are more sensitive comparatively.

Ever wondered if vaping indoors could make smoke alarms go off? It's a common situation, especially when you're at home and tempted to take a quick puff. The answer is yes, vaping can set off smoke alarms, but here's the catch: not all smoke detectors are the same.

Some are more sensitive to vapour than others. In this article, we'll explore the question "Do vapes set off smoke alarms?" and break down what you need to know about vaping indoors and its potential impact on those beeping alarms.

Let's dig deep into the specifics of how these devices respond to the presence of vape smoke.

What Are Different Kinds of Smoke Alarms and Vapour?

There are three primary types of smoke detectors, each with slightly different responses to vapour. Let's explore where and how you can find them:

Optical Smoke Alarms
Heat Alarms
Ionisation Detectors

Optical Smoke Alarms

Think about the smoke alarms you often see in homes – those are optical smoke alarms.

They work by sending out a beam of light, and when smoke crosses this path, it sets off the alarm.

Interestingly, these alarms are quite sensitive to vapour because they can't tell the difference between smoke and vapour.

Heat Alarms

You've probably noticed heat alarms in kitchens and older homes – they look quite similar to optical alarms but have this distinctive cone-shaped thing in the middle.

Unlike other alarms, these pick up on extreme heat rather than vapour, so they're less likely to go off because of your vape.

But here's the thing: if you happen to stand right underneath it, and the sensor is super sensitive, it might still beep at you.

Ionisation Detectors

Picture ionisation detectors as emitting energy around a plate, and if something thick like smoke gets in the way, the alarm goes off.

These detectors are kind of like heat detectors – they're not easily set off by vapour. Just steer clear of standing right below them, and you should be good.

You'll often see this type of alarm in public places and offices.

Can You Vape On A Plane?

Even though it's against the rules, some folks try to vape on planes. But seriously, we strongly recommend against it.

The smoke detectors on planes are super sensitive for important safety reasons.

If the alarm goes off, it could mean the plane has to change course and make an emergency landing, and that might get you fined or even arrested.

So, if you're on a long flight, it's better to consider other ways to handle nicotine cravings, like using sprays, gum, or lozenges.

In a candid conversation with a passenger who was really craving nicotine during a flight, they shared that instead of waiting, they decided to secretly vape in the aeroplane bathroom.

Unfortunately, things took a wrong turn – the fire alarms went off, and the plane had to make an emergency landing, causing a lot of chaos.

The person I talked to couldn't say exactly what happened to them afterward, but they probably got a big fine.

The point is, that trying to vape on a plane is a bad idea. It not only breaks the rules but can cause serious trouble for everyone on board.

So, it's better to find other ways to manage cravings, like using nicotine replacements, and avoid messing with the safety rules on aeroplanes.

Can You Vape In A Hotel Room?

The hotel's stance on vaping depends on where you stay. Big chain hotels usually say a firm "no" to both smoking and vaping.

Other places might not mention vaping rules, but it's always a good idea to ask and go along with what the hotel prefers.

If, by chance, your vaping sets off a fire alarm, everyone might have to leave the building, and that means emergency services will be tied up when they might be needed elsewhere.

Plus, you could end up with a hefty fine because the hotel might think you were smoking. So, it's best to be cautious and respect the rules to avoid any trouble.

How likely is it that my electronic cigarette could set off a fire alarm?

Luckily, it's not common for electronic cigarettes to set off fire alarms. According to a study, the stuff in e-liquids like PG and flavourings might create bigger particles than the steam from your regular kettle.

Even those fog machines with propylene glycol can make fire alarms go off

You see, smoke alarms are designed to pick up on smoke, but e-cigarettes produce vapour, which clears away faster than smoke.

Yet, there's a bit of a catch.

So, the odds of your e-cigarette triggering a regular fire alarm are pretty low, but it's not entirely out of the picture. Just something to keep in mind!

How to vape without setting off a fire alarm?

To play it safe and avoid setting off the fire alarm, here are some smart tips. And seriously, no matter what, never mess with the fire alarm. With 37,000 house fires a year just in the UK, it's just not worth taking chances with your life or anyone else's.

1. Direct Vapour Away from Smoke Alarms

Identify the location of smoke alarms and make sure to blow vapour in the opposite direction. If you're in an office setting, consider positioning your desk away from the alarm. In our experience, when one of our staff members accidentally triggered the alarm, we took the step of relocating their desks to prevent a recurrence.

2. Utilise the Window

Opening the window allows the air to disperse the vapour. For optimal safety, direct the vapour outside through the window.

3. Opt for a Subtle Device

Consider using a device that produces minimal vapour, like an E-cigarette, a pod system, or a pen-style device. Choose a device with lower power for added discretion.

Typically, it's advisable to use a higher resistance coil, usually above 1 ohm, although some modern coils have resistances below 1 ohm for Mouth-to-Lung vaping.

4. Pick E-Liquids Wisely

Also, think about the kind of e-liquid you're using. High VG ones create big vapour clouds, and they're not great for keeping things low-key.

They work better with powerful devices, not the discrete ones we talked about earlier.

So, go for e-liquids with more PG. For example, Halo Vapour Co has a 50:50 VG:PG ratio, and VapeMate has a 30:70 VG:PG ratio.

Explore a variety of E-Liquids available at our shop, carefully selected to cater to your preferences and enhance your vaping experience.

Whether you prefer the balanced 50:50 VG:PG ratio of Halo Vapour Co or the smooth 30:70 VG:PG blend from VapeMate, our selection caters to your preferences.

5. Leave the Fire Alarm Alone

Even if you're worried about it going off, never mess with the fire alarm. It's a risky move that can put people in danger, and it might even be against the law.

Keep in mind, it's a good call not to vape where they've got a no-vaping rule – you wouldn't want to risk a fine or give vapers a bad reputation.

How To Spot Fire Alarms?

Identifying fire alarms involves recognizing specific features of different types.

Optical smoke alarms typically have a line of air holes on the exterior shell, but they can be confused with other types.

To distinguish, one can type the model number into Google for clarification.

Heat alarms resemble optical alarms but often have a wheel or disk fitting in the centre.
Ionisation alarms often have fan-like air holes, but differentiating between ionisation and optical alarms can be challenging.

Checking the model number and searching on Google can provide confirmation. Understanding these distinctions helps in spotting and identifying fire alarms correctly.

Frequently Asked Questions

What type of smoke alarm is least likely to be triggered by vaping?

Heat alarms are less likely to be activated by vaping because they sense sudden or significant temperature changes instead of detecting smoke or vapour particles in the air.

Can the VG/PG ratio of my e-liquid affect the likelihood of setting off a smoke alarm?

Certainly, e-liquids or vape juices with higher VG ratios generate denser vapour clouds, increasing the likelihood of triggering smoke alarms. This risk is particularly pronounced with Ionisation and Optical alarms, as the greater presence of vapour in the air provides more substance for these alarm types to detect.

Is it safe to disable or cover my smoke alarm while vaping?

Our recommendation is against disabling or covering your smoke alarm, as this compromises your safety in case of a fire. Always prioritise safety and consider alternative solutions, like ensuring proper ventilation or using a device with lower power.

How many cigarettes are in a vape?

The ratio between cigarette and vaping consumption is influenced by several factors, including vaping style, nicotine strength, VG/PG ratio, and others.


To sum it up, when it comes to vaping and smoke alarms, it's about being smart and safe. The big question is, "Do Vapes Set Off Smoke Alarms?" We found out that it depends on a few things like what you're vaping and where you are.

If you're using good practices – like blowing vapour away from smoke detectors, opening windows for fresh air, and using devices and liquids that aren't too flashy – you can enjoy vaping without causing trouble. It's all about being considerate and following the rules, so everyone can stay safe and happy. Remember, messing with smoke alarms is a big no-no – safety always comes first!
