2.17 Hazards caused by the hydraulic system
WARNING
Hydraulic fluid may cause irritation of the skin. Leaking hydraulic fluid may damage
the environment. High pressure and partially high temperatures exist within hydraulic
systems. Hydraulic fluid emitting at high pressure may enter the body through the skin
and cause the most severe tissue damage and scalding. If work on the hydraulic sys-
tem is carried out incorrectly, tools or machine parts may be flung away with great
force and cause severe injuries.
Protection
– Regularly check all hydraulic hoses for their condition and immediately have dam-
aged hoses exchanged by trained specialist personnel.
– The hydraulic hoses must be regularly checked following the recognized rules of
technology and the regionally applicable safety regulations, and in case of need,
replaced.
– Works on the hydraulic system have to be performed only by specially trained staff.
– When working on the hydraulic system, first make it pressureless! Avoid skin con-
tact with hydraulic oil.
2.18 Hazards caused by pneumatic system
When working on the pneumatic system there is a risk that compressed air may
escape suddenly and cause injuries.
– All work on the pneumatic equipment must always be carried out by qualified per-
sonnel.
– All pneumatic pressure lines and pressure vessels must be depressurised and
vented before maintenance work.
2.19 Hazards caused by hot substances/surfaces
Burning hazard/hazard of scalding due to:
Hot surfaces (hot machine parts).
Hot engine oil.
Hot hydraulic oil.
Hot coolant.
Counteractive measures:
– Let machine and operating supplies cool down.
– Wear protective gloves.
