Qualified personnel

Due to their specialized training, knowledge and 
experience as well as their knowledge of the 
relevant standards and regulations, qualified
personnel are able to independently perform the 
work assigned to them as well as to detect and 
avoid possible risks and dangers.

2.5 Personal safety equipment

Personal safety equipment is used to protect 
personnel from hazards or dangers that might 
impair their safety or health during work.

When performing the various tasks at, and with 
the device, personnel must wear personal safety 
equipment. Special reference is made of this in 
the individual chapters within these Operating
Instructions. The following provides a description 
of the personal safety equipment:

Always wear appropriate personal safety 
equipment required in the various chapters of 
these Operating Instructions before 
commencing work.

Comply with the personal safety equipment 
instructions posted within the work area.

Description of personal safety equipment

As specified in the Safety Data Sheet of the 
medium, protective equipment must be worn 
when handling hazardous media. In addition,
the specifications of the system operator must be 
followed. If no protective equipment is specified,
suitable protective gloves and goggles must be 
worn.

The protective equipment is used to protect 
against hazardous media leaks and hazardous 
media residue in the device.

Goggles

The goggles are used to protect the eyes from 
flying debris and splashing fluid.

Protective gloves

Protective gloves protect the hands from friction, 
burns, grazing, abrasion, surface cuts or deeper 
injuries, as well as from direct contact with hot or 
cold surfaces.

2.6 Environmental protection

Notice!

Risk to the environment due to improper 
handling of environmentally hazardous 
substances!

Serious environmental damage may result if 
substances harmful to the environment are
handled incorrectly, especially if they are 
disposed of improperly.

Always observe the instructions listed below 
on the handling and disposal of substances 
harmful to the environment.

If harmful substances are released into the 
environment, take immediate 
countermeasures. If there is doubt, contact the 
local authorities, inform them of the damage 
and request information on suitable 
countermeasures to be taken.
