Can a Vape Set Off a Fire Alarm? What To Know

Can a Vape Set Off a Fire Alarm? What To Know

September 24, 2021

Say you're vaping in your sitting room. You press down on the button, inhale, and exhale. You open your eyes in relaxation and look toward the ceiling—right at a fire alarm. Should you panic?

Many people who vape have been through this same thought process. But unfortunately, there's no simple answer to the question. Vapes, like people and fire alarms, come in all shapes, sizes, and sensitivity levels.

But there are some baseline things to know about vaping and fire alarms. In what follows, RELX will guide you through everything you need to know about vaping safety and vaping discretion, vis-a-vis fire alarms and smoke detectors.

What Sets Off a Fire Alarm?

Though they're almost universal within dwellings of all types, the history of fire alarms doesn't go back too far. It was only in 1890 that Francis Robbins Upton created the first fire alarms for home use. These devices got smaller, more sophisticated, and better at doing their jobs throughout the next century.

Related to the fire alarm was the advent of the smoke detector. Walter Jaeger, a Swiss physicist, accidentally invented this device while trying to create a technology to detect poison gas. Jaeger’s invention was still too expensive for commercial sale, but Duane D. Pearsall and Stanley Bennett Peterson improved on Jaeger’s invention in 1965, creating the first smoke detectors for residential application. 

These breakthroughs have saved countless homeowners from fire breaking out in their houses. But the technological innovations do pose some drawbacks. 

Now that these devices have become so sensitive, it's not just smoke and flames that trigger them. It could be smoke or vapour from any number of things. 

As a vape user, how worried do you need to be?

Understanding what can trigger a fire alarm is the first step to knowing how to vape around them.

Fire

The most common cause for setting off fire alarms is, naturally, fire. Most alarms use a process called ionisation to detect smoke. 

Fire alarms house a system in which air passes through a chamber that contains a small amount of radioactive material. When smoke enters the system, it disrupts the flow of ions and activates the alarm.

Fire isn't the only source of smoke that can disrupt the ionisation process, however.

Smoke from Cooking

According to Northern Ireland Direct, the leading causes of home fires are cooking and cooking appliances. But even before a cooking fire, cooking can activate the alarm.

Just that column of smoke coming off chicken or mushrooms cooking at high heat can trigger a smoke alarm.

Insect Interference

One of the strangest reasons fire alarms get activated is because of bugs. All smoke detectors have small vents through which the smoke passes. Those vents are also attractive to flying bugs, who like to burrow.

Sometimes, bugs get inside the alarms and mess with the wiring, causing the alarm to sound.

High Concentrations of Moisture/Humidity

Most people don’t place smoke detectors in bathrooms. The reason for that is the moisture buildup in rooms with appliances like showers. 

If too much humidity or condensation builds up in a room, it may trigger a smoke detector. 

Too Much Dust

It's not just smoke and vapour that can act as triggers. A kickup of a concentrated amount of dust can also set off inaccurate readings.

Dust consists of a fine, silt-like powder. It's so fine that if ventilated into a fire alarm, it can resemble smoke and trigger the alarm.

The risk of accidental alarm triggering is perhaps one more reason to keep up on your spring cleaning.

Chemicals in the Air

Chemicals in the air are another thing to be careful of if you have your smoke detector installed in your kitchen. A circulation of too much chemical product in the air can trigger a fire alarm. 

Can a Vape Set off a Fire Alarm? 

The answer is yes, but the likelihood is rare. You have to be vaping pretty close to a fire alarm and exhaling quite vigorously to set off the device.

Reports of fire alarms going off from vapour are scant because the vapour dissipates much faster than smoke. But it does happen.

The good news is that there are proactive measures you can take to mitigate the risk of accidental alarm triggering. 

How to Vape Carefully When Near a Fire Alarm

Know How Much Vapour Your Vape Produces

Not all vapes have a similar design or construction. Some produce bilious clouds of vapour, some only tiny wisps. It also depends on whether you're using a vape, vape mod, or pod-mod

Know how much vapour your vape produces before you decide to vape indoors in the presence of a fire alarm.

Try Not to Vape Directly Under the Alarm

Once you get your head around vaping and fire alarms, this should be a no-brainer. But it bears repeating: don't vape directly under a fire alarm or smoke detector.

You should avoid this even if your vape produces hardly any vapour. The clouds can act as smoke and trigger the ionisation detector in the device. 

If a vape were ever to set off a fire alarm, it would be from this, so try and avoid it.

Vape Near an Open Window or Doorway

One of the best ways to mitigate the risk of setting off a fire alarm is to vape near a passageway, like a door or open window. That will ventilate the vapour even faster.

Blow Vapor Away from the Alarm

The last thing you can do is simple. When you exhale, simply blow the vapour away from the alarm. If too much vapour concentrates around it, it may trigger. 

If you blow vapour in the direction away from the alarm, you're keeping yourself safe.

Responsible Vaping

At RELX, we believe that it is important to vape responsibly. That means knowing how to keep your fire alarm activation risk at a minimum.

Vape juice, or e-liquid, is a principal component of the vaping experience. Some swear by bubblegum flavours, others are stalwart supporters of the mellow apple and wouldn’t dream of trying more radical incarnations.
