Working at height
WARNING!
Risk of a fall when you work at height!
Working at height without using any fall protection
equipment, or using unsuitable or damaged equip-
ment to get up to where you work at height, may lead
to yourself or others falling from height; people on
the ground may be at risk from falling parts or tools.
This can cause serious or even fatal injuries.
–
Only use equipment that is suitable, stable and
strong enough for the job, maintained and
checked regularly.
–
Stop materials or objects from falling.
–
Wear safety shoes, protective clothing and a
hard hat.
–
Wear a safety harness.
Interconnecting units and systems
WARNING!
Risk of injury from interconnecting different
units or systems!
Connecting an air handling unit to other units or sys-
tems (e.g. ductwork, pumps, refrigeration systems)
can lead to dangerous situations and eventually
cause serious or even fatal injuries.
–
If you have to connect other units or systems to
the air handling unit, connect them professio-
nally.
–
The system owner/HVAC contractor is respon-
sible for the planning and installation of any addi-
tional safeguards.
Sharp edges, sharp corners and thin sheet metal
parts
CAUTION!
Danger of injury from sharp edges, sharp cor-
ners and thin sheet metal parts!
Sharp edges, sharp corners and thin sheet metal
parts of the heat exchanger or of the cooling or
heating coil may cause cuts or grazes.
–
Be careful when working on these components.
–
Wear protective gloves, safety shoes and a hard
hat.
Crushing hazard.
WARNING!
Crushing hazard from movable parts!
There is an increased risk of crushing on casing
units, doors, panels and components of the device.
–
Never reach between moving parts.
–
Be careful when carrying out any work.
–
Wear protective gloves, safety shoes and a hard
hat.
Inspection access doors slamming shut
WARNING!
Risk of crushing from doors slamming shut
Inspection access doors may slam shut by the wind
or if someone pushes them inadvertently, resulting in
serious injury to the head and limbs.
