What is an explosive atmosphere?

An explosive atmosphere is defined as a mixture of dangerous substances with air, under atmospheric conditions, in the form of gases, vapours, mist or dust in which, after ignition has occurred, combustion spreads to the entire unburned mixture. Many workplaces may contain, or have activities that produce, explosive or potentially explosive atmospheres.

Examples include places where work activities create or release flammable gases or vapours, such as vehicle paint spraying, or in workplaces handling fine organic dusts such as grain flour or wood. Safe, reliable communication is a critical tool in such dangerous environments. That’s where the power and performance of MOTOTRBO ATEX intrinsically safe digital radios stand out.

Everything about the DP4000e ATEX radios are designed for worker safety. Loud, clear performance and innovative features like Intelligent Audio and Transmit Interrupt help ensure messages get through in the noisiest environments.

Like the radio, Motorola’s audio and energy accessories meet the most stringent ATEX/ IECEx standards. An Integrated Man Down and Lone Worker feature sends an instant alert if a mishap occurs. And the bright blue colour helps ensure workers can quickly identify and carry only ATEX/IECEx-approved radios into hazardous environments.

The DP4000 Ex Series features large PTT, volume, channel knobs and programmable buttons that are easy to use, even when wearing gloves. The large, colour display (DP4801 Ex only) and bright LED show radio status information at a glance.

Plus the prominent orange emergency button enables workers to quickly call for assistance when needed.

Explosive atmospheres in the workplace – what are the ATEX classifications?

In Great Britain, the requirements of Directive 99/92/EC were put into effect through regulations 7 and 11 of the Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR).

The requirements in DSEAR apply to most workplaces where a potentially explosive atmosphere may occur. Some industry sectors and work activities are exempted because there is other legislation that fulfils the requirements. These exemptions are listed in regulation 3 of DSEAR. The ATEX directive requires all products to be marked with the CE mark, the ‘EX’ mark and the equipment coding.

Heading Mark Use
Explosion proof in accordance with the ATEX directive
Equipment Group I For use in underground mines
II For use in all other places
Category 1 Equipment that is intended for use in areas where an explosive atmosphere is present continuously, for long periods or frequently
2 Equipment that is intended for use in areas where an explosive atmosphere is likely to occur in normal operation and must ensure a high level of protection.
3 Equipment that is intended for use in areas where an explosive atmosphere is unlikely to occur in normal operation and must ensure a normal level of protection.
Gas / Dust G Equipment certified for use in flammable gases
D Equipment certified for use where dust is present in the atmosphere
Type of Protection* d Flameproof
Ia Intrinsically Safe
e Increased safety
Gas Group I Mines
II Surface above ground industries
Gas Sub Group A Less easily ignited gases e.g. propane
B Easily ignited gases e.g ethylene
C Most easily ignited e.g. hydrogen or acetylene
Temperature Classification
Hazardous area apparatus is classified according to the maximum surface temperature produced under fault conditions at an ambient temperature of 40°C, or as otherwise specified. The standard classifications are as shown
T1 450ºC
T2 300ºC
T3 200ºC
T4 135ºC
T5 100ºC
T6 85ºC
