Refrigerant

Refrigerant is used in the machine's air conditioning system.
Work on the air conditioning system must be performed by accred-
ited/authorised and trained personnel according to national legisla-
tion and local regulations.
Risks
The air conditioning operates at high pressure. Escaping refrigerant
can cause frostbite.
Refrigerant that is heated (e.g., when repairing leaking climate/AC
system), generates gases that are very dangerous to inhale.
Safety actions
• Use special instructions and equipment for refrigerant accord-
ing to the manual when working on the air conditioning system.
Special certification and authorization is often required of the
person who may do the work. (Note national legislation and lo-
cal regulations!)
• Use protective gloves and safety glasses if there's a risk of leaks.
• Make sure that heat-producing sources or objects are not close
by (cigarette glow, welding flame).

Air pollution

Air pollution is the impurities in the air around us and which are re-
garded as hazardous to health. Certain pollution is more prominent
in certain environments.
The following health-hazardous air pollution is especially prominent
in workshops:
• Carbon monoxide (fumes) is present in exhaust fumes.
Odorless and therefore especially dangerous.
• Nitrogen oxides (nitrous gases) are present in exhaust
fumes.
• Welding smoke especially hazardous to health when welding
on oily surfaces, galvanized or lacquered materials.
• Oil mist for example, when applying anti-corrosion agent.
• Grinding dust and gases generated when grinding and heat-
ing plastics, lacquer, anti-corrosion agents, lubricants, paint,
etc.
• Isocyanates are present in certain paints, fillers, adhesives
and foam plastics used on machines.
