1.3 Safety at work
Before installation or carrying out maintenance work on the device, safe access
must be ensured and a secure working area with sufficient lighting must be
defined and marked out. Always use lifting equipment for heavy loads!
Before starting any work, carefully check which liquids or gases are or have been in the
pipeline. (flammable substances, irritating substances, substances hazardous to health) When
opening or dismantling the device, residues of the medium can escape. Subsequent fumes
are also possible in unpressurized and cold systems. Use designated PPE such as safety
goggles and respiratory protection!
Special attention must be paid to the condition of the environment around the installation or
maintenance site. Be aware of e.g.: potentially explosive atmospheres, lack of oxygen in tanks
and pits, dangerous gases/liquids, extreme temperatures, hot surfaces, fire hazard (e.g. during
welding) and moving machine and system components. Protect yourself from excessive noise
by taking the required protective measures.
For all maintenance work or new installations, on new or existing boilers or vessels, it is
imperative to check that the boiler or vessel has been depressurised and that the pressure has
been safely reduced to atmospheric pressure. In principle, no system should be regarded as
unpressurized even if indicated by pressure measuring devices such as pressure gauges or
sensors. When releasing the pressure, make sure that no persons are in the release area.
Carefully check whether you and/or other persons in the vicinity need PPE to protect yourself
from external influences such as high and low temperatures, radiation, noise, danger to eyes,
loose objects that can fall down or chemicals.
There is always a risk of injury when handling large and/or heavy equipment. Observe the load
handling regulation as a minimum requirement for working with loads. Avoid handling the
device with your own physical force, e.g. by lifting, pulling, carrying, pushing or supporting it,
especially to prevent back injuries. Use lifting equipment to move heavy and bulky equipment
in accordance with Article 1, Section 2 of the German Load Handling Regulation
(LasthandhabV).
Under normal operating conditions the surface of the device can become very
hot! Under the maximum operating conditions, the surface temperature can
exceed 350°C. After shutting off or, if necessary, shutting down the boiler, wait
until the temperature has normalized to room level. To avoid the risk of burns
and scalds, always use PPE including safety goggles!
