To carry out explosion hazard inspections the competent person must
have:
n Completed a relevant course of study or
n Have a comparable technical qualification or
n Another technical qualification combined with long-term experience of
safety technology.
Make sure that the person is familiar with the relevant body of standards
and regulations and has worked in the field for at least one year. The
person needs to have opportunities for an exchange of experiences.
Specific requirements are placed on competent persons who perform tests
on repaired devices/parts. They must be recognised by the responsible
authorities (e.g. district council) in this respect.
WARNING!
ATEX pumps in areas at risk from explosion
– The operator must observe the Operator Directive
when operating equipment in areas at risk of explo‐
sion.
–
Only clean plastic parts carefully with a damp cloth
to avoid electrostatic charges and sparks.
WARNING!
Motor may overheat
If the necessary cooling air supply is not guaranteed, the
motor may overheat. In an area at risk from explosion, it
could trigger an explosion.
– Maintain sufficient clearance between the air intake
opening and the walls. The distance should be
greater than 1/4 of the diameter of the air intake
opening.
–
The fan must not suck in the exhaust air from other
devices.
WARNING!
ATEX pumps in areas at risk from explosion
– Metering pumps must have an appropriate safety
relief valve on the discharge side (to protect against
excessive heating due to overloading or impact
sparks caused by the breakage of power end parts).
WARNING!
ATEX pumps in areas at risk from explosion
– A flow control is needed to stop the pump as soon
as no flow is detected.
