L.1.6
Filters
L.1.6.1
Risk caused by missing change of filters
Hazards/dangerous area:
• Missing change of filters and missing maintenance decrease the capacity and final consequence will be breakdown.
Dangerous incident:
• By extensive lack of of filter change and maintenance the machine can break down.
Claim for reduction of danger:
• In the manual is the method and schedule for change of filters and maintenance specified.
L.1.6.2
Risk caused by the execution of filter change
Hazards/dangerous area:
• Filter panels and filter bags
Dangerous incident:
• To breathe in particles that is harmful to the health.
Claim for reduction of danger:
• Use of particulate respirator – maintenance free including foam face-seal and adjustable pre-threaded headbands
(same particulate respirator as recommended for cleaning of attenuators.
L.1.7
Plug fans
L.1.7.1
Risk caused by lightning strike
Hazards/dangerous area:
• Lightning strike close to the machine.
Dangerous incident:
• Lightning strike can create flash over between phases and conductive parts. This can cause fire or the overvoltage
can make injury on persons
Claim for reduction of danger:
• Installer and user must be aware of the fact that lightning makes a risk that requires installation of overvoltage pro-
tection devices to lead the lightning overvoltage to an earth lead on a safe way. The need for overvoltage protection
devices depend on where the unit is placed in and on the building.
• Installer and user must take care of this according to local statutory requirements. Overvoltage protection devices
are also described in chapter I.3.3.2 of this manual.
L.1.7.2
Risk caused by permanent magnet motor
Hazards/dangerous area:
• Rotation of the shaft generates electricity. This danger is always visualized by a yellow warning label on the inspec-
tion door where permanent magnet motors are installed.
Dangerous incident:
• Persons touching conductive parts get electric shock, burns, heart flicker and so on.
Claim for reduction of danger:
• By installation or repairs of conductive components, the shaft must be blocked to prevent any rotation.
