Do Vapes Set Off Smoke Alarms and Fire Alarms?

If you’re an adult vaper and you use your vape indoors, you may have questions like, do vapes set off smoke alarms? You may want to know whether using your vape indoors can set off a fire alarm and what the differences are between smoke and fire alarms. Depending on where you are vaping, there may be ways to minimise the risk of triggering alarms. 

What’s the Difference Between Fire Alarms and Smoke Alarms?

There are multiple types of smoke and fire alarms. Understanding the differences between these devices may help you know whether they can be triggered by vaping. Smoke alarms, also known as smoke detectors, identify the presence of smoke in a room. The smoke detectors are there to notify the fire alarm. The fire alarm is the sound that alerts people in the building to let them know there is a fire. 

Do Vapes Set off Heat Alarms? 

Heat alarms are unlikely to be set off by vaping. Vapes typically do not produce enough heat for the vapour to be detected. Heat alarms are usually only found in kitchens.

Do Vapes Set off Ionisation Alarms? 

Although this is unlikely, there have been instances of vapes setting off ionisation alarms. These alarms typically trigger when particles disrupt the internal mechanisms.

Do Vapes Set off Optical Alarms? 

This is the most common type of alarm, and it’s found in most households. It is also the most likely to be set off by a vape, although this is still rare. An optical alarm could be activated when vapour enters the system and interferes with its internal infrared light. 

Can a Vape Set off a Fire Alarm on Public Transport or in Hotels?

You may wonder if vapes trigger smoke alarms in public or private places. Vaping in these locations could potentially set off a fire alarm. As vaping is often restricted on public transport and in most hotel rooms, it is best to find a place where you can use your vape - either before you board public transport and outside your hotel or in a designated area. 

Do Vapes Set off Smoke Detectors on Public Transport?

​​Vaping on public transport is typically prohibited in the UK, and it could trigger smoke detectors. It’s best to wait until you have reached a more suitable location to use your vape. 

Do Vapes Trigger Smoke Alarms in Hotels and Rental Properties?

Vaping could trigger the smoke alarm in private places like hotels or rental properties. The rules around vaping indoors in these locations can vary depending on the establishment. If you’re unsure whether vaping is permitted inside, you should always ask before vaping and adhere to the guidance provided.

It is often illegal to vape in these locations. Therefore, we advise not vaping until you find a suitable and legal location.

How can I Minimise the Risk of Setting off Alarms when Vaping Indoors?

If you’re vaping indoors at home, there is a small chance that vapes set off smoke alarms and fire alarms. However, there are some ways you may be able to lower the risk of triggering alarms when vaping. It is important to avoid vaping in a location where it is not allowed. The below guidance is only relevant for adult users vaping in a place where it’s permitted.

Vape in a room with good ventilation

To minimise the chance of setting off fire and smoke alarms, try to vape in a room with good ventilation. You can do this by keeping the windows open or choosing to vape in larger and more open rooms.

Vape at a distance from the detector

Try to locate the smoke detector in the room you are vaping in, and ensure you are as far away as possible. This will reduce the chance of the detector sensing the vapour and triggering the fire alarm.

Minimise cloud production

When vaping indoors, try to minimise cloud production to lessen the chance of vapour triggering smoke and fire alarms.
