Safety
3.1
Basic safety instructions
Klein blowers are designed and produced in accordance with generally accepted technology,
occupational and accident prevention practices and in accordance with the requirements of
the ATEX- directive for machines and protective systems for the designated use in explosive
environments, as well as the requirements of the Machine and Product Safety Act [GPSG or
equivalent other national regulations]. They correspond to the state of the art.
Nevertheless, blowers in operation can be the source of hazardous conditions, especially
when hazardous conditions are created as a result of
inappropriate use or
non-designated use
.
For this reason, all instructions for the use of the blower must be adhered to.
