Ignition Hazard Assessment - GCE Samplers
Guarding of Moving Parts
GCE samplers have hazardous moving parts which present a risk of serious injury when unguarded.
The samplers operate under automatic control and may start unexpectedly and without warning.
1. Guards are provided to enclose all moving parts except those involved in the sampling process.
2. Moving parts involved in the sampling process shall be made inaccessible at installation by enclosing
both the inlet and outlet of the sampler such that the moving parts cannot be reached by any part of
the human body.
3. Generally this is achieved by close coupling the sampler inlet and outlet to the upstream and
downstream conveying system.
4. Where this is not suitable (ex: open hopper inlet), the installer must ensure access to the moving parts
is restricted in accordance with EN ISO 13857 or through other methods (ex: interlocking controls).
5. Under certain circumstances it may be necessary to remove guards. Only do this when the sampler
and other associated equipment is isolated and locked out from the power supply.
6. Never operate the sampler with the guards removed.
