1.26 Residual ATEX risks
Residual risk
Possible in
lifecycle
Avoidance / Remedy
Use in a potentially explosive atmosphere
without checking equipotential bonding
for electrical continuity
C, D, G
Check the equipotential bonding for continuity before first start-up, after every repair, and ad-
ditionally at regular intervals defined by the operator
Use with a damaged, incorrect, or miss-
ing ATEX finish
C, D, E, F, G
Prior to first start-up and then at regular intervals, inspect the varnishing and if necessary
have it replaced by a person competent to do so
Heating of non-supplied lubrication
points to the ignition temperature range
by an undetected malfunction within the
centralized lubrication system
C, D, G
The operator must critically examine whether operation without corresponding detection op-
tions results in a new hazard potential (e.g., due to heating of non-supplied bearings on the
machine to the range of the ignition temperature); if this cannot be reliably excluded, take ap-
propriate countermeasures
Heating of components to the ignition
temperature range / formation of a
potentially explosive atmosphere by agi-
tated/swirled dust
C, D, E, F, G
Avoid accumulated dust / remove accumulated dust on a regular basis; select an installation
location with the lowest possible dust level
Lifecycles: A = Transport, B = Assembly, C = First start-up, D = Operation, E = Cleaning, F = Maintenance, G = Malfunction, repair,
H = Shutdown, K = Disposal
