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!
