What is an explosion proof camera and How it works?

According to the latest Mordor Intelligence report, the industry size of the Asia-Pacific explosion-proof equipment market is projected to be worth USD 2.76 billion in 2024 and rise at a compound annual growth rate (CAGR) of 9.06% to reach USD 4.25 billion by 2029. Rapid industrial growth marks a sharp rise in the hazards and explosion risk in these industries. 

Explosion-proof cameras are specially built devices designed for hazardous areas. They are also known as Zone 1 cameras since they can be used in areas with combustible gases. These cameras are best suited for hazardous industries such as oil & gas, manufacturing, mining, construction, marine, etc.

‍

Certification Process

Testing and certification are crucial processes that ensure product quality and potential usage. The enclosures of explosion-proof cameras are specifically made to exclude or confine any possible ignition sources. By avoiding sparks, arcs, and other possible ignition sources, the certification confirms that the camera can function safely in areas with combustible materials. Certification also helps customers make prudent decisions throughout their buying and analysing process. 

In most developed countries, electrical devices that operate in hazardous environments are required to pass a test of rigorous specifications to get certified. Different countries use different certification terminology:

• ‍The US utilises the division system illustrated in the National Electrical Code to categorise explosion-free electrical equipment. These devices should possess a label with the name of the factory, the certificate issuer, the file number, and the marking according to NEC 500-506.
• ‍In Canada, the guidelines provided by the CEC (Canadian Electrical Code) are deployed for equipping warehouses or manufacturing plants. 
• In other parts of the world, the zone system is followed. The Zone system is a method used to classify and designate the level of risk potential of the atmosphere. 
• ‍In Europe, manufacturers must get the ATEX (Atmosphere Explosible) Certification before using explosion-proof devices available in the market. ATEX certification ensures the effective functioning of appliances in explosive territory without provoking any disaster. Manufacturers must follow the ATEX directives for optimum device manufacturing. 

Additionally, manufacturers must also include the code number of the quality control agency along with the label. Labelling includes the type of protection, temperature level, list of equipment, and equipment protection grade.

Facts About The Explosion-proof CCTV Camera

‍Sectors like chemical, gas, and processing industries prefer explosion-proof cameras to avert hazardous situations. It is evident that the chances of fire-related accidents in oil refineries or even gas stations are high. Hence, to ensure worker's safety and the company's safety, a company must deploy cameras that are capable of containing sparks and hardy for harsh conditions in the industry. Industries such as grain storing and wood manufacturing are also recommended to deploy safety devices, such as explosion-protected cameras, due to the high combustibility of dust particles.

How to Find a Suitable Explosion-Proof Cameras

‍Before digging into the details of different explosion-proof CCTV cameras, here’s a checklist to look into to find a suitable camera for your needs:

• The first thing you need to know before buying a device is its key specifications and operating system.
• You should know that these Zone 1 cameras are appropriate for regions where the economy is heavily dependent on petroleum and energy.
• ‍Before buying an explosion-proof camera, you must investigate what emerges amidst an explosion. Compare it to the components of a camera that claims to make it explosion-proof. It helps you better determine a camera's reliability in a highly explosive environment. 
• ‍Lastly, we must survey the standard of the product.

‍When does an explosion happen?

‍Explosions can happen when elements like heat and gases come together. Different industries have different explosion-causing triggers, such as fuel, energy, and oxidisers.

It leads to a setting where oxidiser-like air comes close to flammable materials like gas or vapour, creating an explosive atmosphere. Any kind of energy or a slight trace of ignition can easily create a favourable atmosphere to accelerate an explosion or fire.

This energy may come from natural lightning, electromagnetic waves, radiation, surface heat, etc.
