Residual risk

lifecycle
Avoidance / Remedy
Use in a potentially explosive atmo-
sphere without checking equipotential
bonding for electrical continuity
C, D, G
Check the equipotential bonding for continuity before first start-up, after every repair, and
additionally at regular intervals defined by the operator
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
options 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 appropriate 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 installa-
tion 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
