4. Safety regulations
Danger
Compression results in high
temperatures.
There is strong suction at the air inlet.
There is a risk of injury, e.g., from
getting stuck or being drawn in.
Connected compressed air tools may
start up unexpectedly when switching
on.
Compressed air may contain
substances that may damage your
health if inhaled.
The pressure relief valves in the system
only guarantee the pressure relief for
the compressor unit.
As a rule:

Safety measure required
The system should be set up such that hazardous mixtures (inflammable
solvent vapors etc. but also dusts and other dangerous or toxic materials)
cannot be drawn in. The same applies to flying sparks.
Never use the machine in environments where the possibility cannot be ruled
out that inflammable or toxic vapors may be taken in.
The installation is to be set up in such a way that it is adequately accessible
and that the necessary cooling is ensured. Never block the admission of air.
Compressor units must never be operated in areas subject to explosion
hazards! (Exception: Special units with the corresponding technical
modifications)
The air intake is to be designed in such a way that no loose clothing can be
drawn in.
Personnel must not have long, loose hair, or wear loose clothing or jewelry,
including rings, due to risk of injury through catching. Personal protective
equipment should be worn if necessary.
Before switching on the machine / installation, or starting it up, make sure that
nobody can be injured by the machine / installation as it starts up.
The compressed air produced by these compressors must not be used as
breathable air, unless it has been processed specially for such an application
in accordance with the "Safety requirements for breathable air."
When breathing apparatus with cartridges is used, make sure that the correct
cartridge has been inserted and that its service life has not expired.
The pressure devices/systems connected to the compressor must be secured
allowing for the weakest pressurized component (pressure relief valve or
similar).
If several compressors are arranged in a system, manually operated valves
have to be installed so that each machine may be shut off individually. For the
purpose of shutting off pressurized systems, you should never rely on the
effectiveness of return valves alone.
All pressure tanks located outside the unit with an approved operating
pressure higher than atmospheric pressure and fitted with two or more
pressure feed lines must be equipped with an additional safety device to
automatically prevent the approved operating pressure from being exceeded
by more than 10%.
Never operate the system at temperatures and/or pressures below or above
the values indicated in the technical data sheet.
