suitable safety belt.
Before carrying out welding works or using elec-
trical devices, check to ensure there is no dan-

People working in wastewater systems must be
vaccinated against the pathogens that may be
found there. For the sake of your health, be sure
to pay meticulous attention to cleanliness wher-
ever you are working.
Make sure that there are no toxic gases in the
working area.
Observe the health and safety at work regula-
