What Is An
Explosive Atmosphere?

In many industries it is necessary to illuminate areas containing flammable elements, which are potentially explosive if exposed to an ignition source. Electrical equipment, including lighting, used in these locations therefore needs to be completely safe, even in the event of a fault. Ex certification schemes such as ATEX and IECEx exist to demonstrate the suitability of equipment for different levels of exposure to potentially explosive atmospheres.

The two explosive elements are Gas – an air mixture containing flammable gasses, vapours and mist - and Dust – a cloud of combustible materials.

Areas containing gas are classified as Zone II, Zone I and Zone 0 while areas with combustible dust are classified as Zone 22, Zone 21 and Zone 20.

As an example, Zone I hazardous area lighting is guaranteed safe in a location where an explosive atmosphere occasionally occurs.

Zone 0, I, II

Zone 0 is the source of the flammable gas, such as an underground store, inside a tanker or mine. A Zone 0 area is one that is exposed to an explosive atmosphere continuously or for more than 1000 hours per year. This requires the highest and strictest level of certification where electrical equipment must be able to function safely with 2 faults.

A Zone I area is one that is exposed to an explosive atmosphere between 10 and 1000 hours per year, such as the connection between a tanker and a store. This is defined as occasional exposure in normal circumstances. i.e. repair work, maintenance, permissible leakage. Zone 1 areas require a strict level of certification where the electrical equipment must be able to function safely with 1 fault.

A Zone II area is exposed to an explosive atmosphere between 0 and 10 hours per year and is typically the area surrounding the source of the gas. This is defined as unlikely exposure in normal operation for short periods where the gas has escaped in the event of an accident or in the rare case of specialised operations. Zone II is the lowest level of certification where the electrical equipment shuts down safely in the event of a fault.

Zone 20, 21, 22

For dust, the classification is similar:

  • Zone 20 is at the source.
  • Zone 21 is at the connections between the source.
  • Zone 22 is the surrounding area.

Portable Hazardous
Location Lights

For areas without a power supply such as the inside of tanks, or remote parts of a large shipyard, high output battery powered lighting is essential to give full illumination to all areas for inspections, cleaning or painting. Where explosive gases or dusts might be present, your lights must be Ex certified.

Portable lights need to be easy to carry in one hand. Apart from being easier on the arms, it is also vital for health and safety that workers can hold onto a handrail whilst carrying a lamp in the other hand.

BME Nitech’s Guardian range of portable lights are all 8.5 kg or less, making them one of the very lightest portable floodlights on the market.

Whether it’s painting, construction work or inspections, portable lights without any trailing cables are safer and can be placed precisely where you need them to highlight specific features.

A bright, daylight balanced output and long battery life makes the lights easy to work with for the duration of a whole shift.

Temporary Hazardous
Area Floodlights

For larger areas such as construction sites which need bright lighting to enable work to continue after darkness falls, our temporary zone I and zone II floodlights are ideal.

Because they include magnetic and clip mounts they can be attached to scaffolding, rails and walls or can use robust floor stands to be placed exactly where they are needed. The ability to link up to ten lights together from one power source enables you to illuminate a large work site with the minimum of dangerous cables and arrange the lights exactly where you need them the most.

For Use In All Potentially Explosive Environments

ATEX and IECEx certified, our Pioneer Zone I LED and Zone II LED temporary floodlights are suitable for use in all potentially explosive environments, including petrochemical plants. They are also used regularly by security, defence and aerospace organisations such as BAE Systems and by the UK's Ministry Of Defence for major shipbuilding projects.

The use of our specialist hazardous area lighting is not confined to heavy industrial sites, for example, the Guardian Zone II CFL portable light featured in a recent project requiring temporary lighting at a whisky distillery in Northern Scotland.
