ATEX Zones
Mini-Cam equipment is classified according to its approvals for use in different
Environments:
• ATEX-1 – the highest level of ATEX that Mini-Cam equipment supports.
This is specialised equipment containing several high integrity design
and pressure monitoring features, and a means of automatically cutting
off the power supply to the inspection equipment if any low pressure
condition is detected.
• ATEX-2 – this equipment contains good pressure monitoring
features, designed to meet the ATEX-2 regulations for use in explosive
environments, but will NOT automatically remove the inspection
equipment power supply if a low pressure condition is detected.
• NON-ATEX – this equipment still contains pressure sensing features, but
is NOT approved for use in any explosive environments.
You or a qualified person must determine the required level of ATEX
equipment, and you must use only equipment which meets those
levels.
ATEX Compliance and Non-compliance
ATEX equipment can be
Compliant
or
Uncompliant
.
When powered ON, the system continuously monitors the pressures inside the ATEX
equipment. If the pressures are high enough, the equipment is
Compliant
. If they
fall too low, the equipment is
Uncompliant
.
NON-ATEX equipment, even when pressurised, can never be classed as being
Compliant, as it does not meet the other design regulations required for full ATEX
compliance.
If any attached ATEX equipment becomes Uncompliant, then the whole system is
deemed Uncompliant.
