Essential Tips for Installing Flame Arrestors in Hazardous Areas

Flame arrestors are an important safety device that prevents the spread of fire in potentially explosive atmospheres. They are widely used in industries such as oil, gas, chemical processing and manufacturing, where the presence of flammable gases, vapours or dust can pose a serious hazard to people, equipment and the environment. In this blog post, we will explain what to look for when installing flame arrestors in potentially explosive atmospheres.

What is a Flame Arrestor and How It Works

First, it is important to understand what a flame arrestor is and how it works. A flame arrestor is a passive device that is installed in a pipe or vessel to prevent flames or flammable gases from spreading to a protected area. It consists of a number of small openings that allow gases to pass through, but not flames. Once the flame enters the device, it cools and dissipates the heat, preventing the flame from reaching the hazardous area.

Key Considerations When Installing Flame Arrestors

There are a few things to keep in mind when installing flame arrestors. The most important consideration is the location of the hazardous area. Flame arrestors should be installed at the entrances to hazardous areas, such as:

• ventilation openings
• exhaust pipes
• air intakes

It is important to consult a professional engineer to determine the correct installation location.

Choosing the Right Type of Flame Arrestor

Another important factor is the type of flame arrestor required for the specific hazard area. There are different types of flame arrestors, each designed for a specific application. For example, in areas with a high gas or vapour flow, a deflagration flame arrestor is recommended, while in areas with a low flow velocity, a detonation flame arrestor is more suitable.

Size and Material Compatibility

Important factors when installing flame arrestors are the size and compatibility of the device with the pipe or vessel in which it is installed. The diameter of the flame arrestor must match the diameter of the pipe to ensure proper operation. It is also important to select a flame arrestor that is made of suitable materials that can withstand the temperatures and chemical loads in the hazardous area.

Maintenance and Inspection

Finally, regular maintenance and inspection of flame arrestors are essential for their effective operation. It is advisable to establish a maintenance schedule to ensure that the flame arrestor is clean and free of deposits or contaminants that could affect its performance.

In short, when installing flame arrestors in potentially explosive atmospheres, it is essential to consult a professional engineer to select the correct type and size of device and
