Types Of Gas Detectors
These models usually pick up volatile gases in surrounding areas and show the gas concentration levels on the meter.
They are ideal for performing safety checks after new gas installations because they don’t run continuously.
These units are not suitable to use as a substitute for smoke detectors or carbon monoxide detectors.
Stationary gas detectors
Stationary gas detectors are typically installed up high, either on a ceiling or wall. They detect combustible gases and gas leaks. Some models can also detect smoke.
These units are either hardwired to your electrical system or battery-operated and run continuously.
Gas leak detecting sprays are only efficient if you can spray it directly on the precise spot where a possible explosive leak is happening. That’s why we don’t recommend using them.
Gas leak detection pens
Gas leak detection pens are used for detecting combustible gas.
Since they can only detect the gas once you are near the source we do not recommend using them. These units do not run continuously and are unable to pick up carbon monoxide.
Features To Consider
It is important to know which gases can be identified by the unit and which gases can’t.
Some gas detectors are multi-functional and can detect various types of gases and smoke, while others can only detect one specific gas.
Keep in mind, unless the device specifications clearly state that it will detect CO levels, it won’t.
It is advisable to choose a gas detector that has the UL approved mark listed to give yourself self-assurance and peace of mind.
UL listings verify that the unit meets safety standards and has undergone rigorous third-party testing and analysis.
Most units have an expiration date, meaning they are designed to work efficiently for a specific period of time. It is recommended to replace the unit before the expiration date.
When choosing a device, ensure it has a battery power indicator.
The detectors must also be tested every month and the batteries should be tested every year to ensure the units are in good working order.
If the detector is a sealed unit, it must be replaced entirely when the battery fails.
App/Smart home integration
It’s worth looking at whether the gas leak detector you’re buying can be integrated with a smart home system, especially if you already have other smart home appliances installed.
When Gas Is Detected
In the event of a gas leak detection, do the following:
Once you’ve detected an odor that indicates a natural or propane gas leak, evacuate your workplace or home immediately and contact your local gas professional from outside.
Avoid trying to locate the origin of the gas leak yourself.
When a carbon monoxide detection alarm goes off
Make sure everyone is out of the vicinity, including pets. Also, ensure that they are now outside or in a well-ventilated area.
Call your nearest fire department and only enter the vicinity when they give you the go-ahead.
Don’t switch anything off or on
This includes anything from thermostats and appliances to light switches and doorbells. It could result in a spark that can ignite combustible gases.
Avoid ventilating your workplace or office
Wait for the utility company or fire department to locate the source of the leak.
Gas detection devices are incredibly useful tools to have at your workplace or home as they ensure the safety of your family or employees.
