Avon EX750 Rising Arm Barriers are an ATEX / IECEx certified product that have been designed for vehicle control in hazardous areas which are potentially susceptible to explosive atmospheres.
Designed and manufactured in the UK, Avon EX750 Barriers will provide vehicle access and movement control for primarily oil and gas / chemical works sites without creating an ignition source.
The EX750 is a vehicle control barrier that has been specifically designed to mitigate the Health and Safety risks associated with sites with the potential for the build-up of explosive atmospheres.
Key features & benefits
The EX750 CAT2 Barrier can operate in an area that is deemed to be a potentially explosive atmosphere, an explosive atmosphere can be caused by flammable gases, mists or vapours or by combustible dusts. When these dangerous substances combine with air, under atmospheric conditions and ignition has occurred, the combustion spreads to the entire unburned mixture.
Mechanical & electrical equipment that operate in zoned areas should comply with the requirement of the ATEX directive & the IECEx standard.
ATEX and IECEx certified barriers are labelled with a standardised marking scheme that is applied to identify equipment suitable for a specific location.
