Danger to life from poisoning where toxic process media leak from damaged connections
Sudden twisting of the turbopump in the event of a fault causes fittings to accelerate. There is the risk
of damaging on-site connections (e.g., fore-vacuum line) and resulting leaks. This results in leakage
of process media. In processes involving toxic media, there is a risk of injury and danger to life due to
poisoning.
► Keep masses connected to the turbopump as low as possible.
► Use flexible lines to connect to the turbopump where necessary.
