Protect your people and installations with ‘explosion-proof’ security cameras

“In a wide range of industries – from oil & gas, to chemical manufacturers, and processing plants – flammable materials and gases are often present. To protect people and installations in these potentially hazardous environments, ‘explosion-proof’ equipment, including security cameras, is needed,” Jayson Gao, Senior Product Manager of IP Cameras at Hikvision. 

 

At sites where combustible gases, chemicals, powders, or other flammable materials are present, fire and explosions are a constant risk. This means that companies working with flammable materials don’t just need to ensure that employees are working safely and using the right protective gear. You also need electrical and other equipment that is safe, never creating sparks or flames that can lead to a much bigger explosion. 

 

Unfortunately, with traditional security solutions – and CCTV cameras in particular – this is not possible. The plastic casing on most products means that sparks and flames triggered by a short circuit or other fault in the device can quickly come into contact with the atmosphere or nearby equipment. 

 

While you may not be able to control the presence of flammable gases or materials in your environment, you can control the combustion source with ‘explosion-proof’ security equipment, including cameras. These kinds of cameras are not necessarily able to survive an explosion or major fire, but they can ensure that no spark or flames that originate in the device itself can cause wider damage by igniting gases in the environment, or nearby flammable materials or other equipment, for example. 

Take the combustion source out of the equation to minimize fire and explosion risks.

Key features of ‘explosion-proof’ security cameras

To ensure that sparks or flames originating in the device never cause a fire or explosion, cameras and other security devices need to be ‘hardened’ in specific ways. These include: 

 

1) Use of explosion-proof materials for the product’s outer casing

The leading explosion-proof cameras use ‘explosion-proof’ materials to ensure that sparks and flames do not ignite either the atmosphere, or nearby equipment. Typically, this means that the device is entirely covered by an additional layer of stainless-steel – often up to 3.5 millimeters thick. By using this thickness of steel, m
