Tab. 2-2 Leak point danger zone
2.4 Non obvious hazards
Using asphyxiant operating fluids, e.g. nitrogen, can lead to severe injuries or
death by asphyxiation. Assess the risk for the equipment in the risk assessment.
The following are some potential corrective actions:
– Operate the gas booster in an adequately ventilated space.
– Check the gas booster for leaks on a regular basis.
– Ensure that lines are connected in such a way as to remain leak-tight for a
long time.
– If necessary, use connecting lines to remove the escaping operating fluids.
2.5 Residual risks
2.5.1 Start-up and shut down
During the restoration of the pneumatic energy supply, the gas booster may start
up unexpectedly. This can lead to severe injuries or death.
Assess the risk for the equipment in the risk assessment.
There is no command device for safe shut-down (E-stop). This can lead to severe
injuries or death.
Assess the risk for the equipment in the risk assessment.
2.5.2 Risk of injury posed by noise
The noise level emitted in the work area depends on the mounting and applica-
tion.
Assess the risk for the equipment in the risk assessment.
2.5.3 Hazardous operating fluids
Improper use of operating fluids can lead to serious accidents resulting in death.
Assess the risk for the equipment in the risk assessment.
