Prior to working with standard rotating nozzles, the following actions must be taken:
Set up barriers and safety equipment (warning triangle, block off the area, etc.).
The necessary information on the wastewater flowing through the manhole must
be obtained (chemicals, gas, vapors, etc.).
Measuring instruments such as explosive gas meters, oxygen meters, gas warning
devices, etc., must be readily available.
The work area must be blocked off and secured so that there is no risk of falling
or danger from traffic.
Make sure that the appropriate nozzle sizes for cleaning the pipes are available.
The application range of each nozzle is listed in the “Technical data” section on
Page
The layout of the pipes must be known and the drawings must be available before
starting the work. This is to avoid the operating nozzle from emerging at a pipe
end. Support personnel must be on hand to monitor possible emerging points.
Have the liability waiver signed to protect against any possible damage claims.
