Hazards caused by pneumatic system
2.16 Hazards caused by noise
WARNING
Noise
Noise can cause loss of hearing (deafness), hearing defects, health disorders such
as loss of balance or consciousness disorders, as well as disorders of the heart and
circulation. Noise may lead to reduction of the attention of people. In addition, noise
may interfere with verbal communications among operating personnel as well as to
the outside world. Perception of acoustic warning signals may be impaired or blocked.
Protection
– Wear ear protection (cotton wool, earplugs, capsules or helmets).
– Keep sufficient distance to operating machine.
Possible causes:
Pulse noise (< 0.2 s; > 90 dB(A))
Machine noise in excess of 90 dB (A)
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
In case of damage to the pneumatic system, the raised warning signs on the pile
pickup may suddenly come down and cause severe injury to people located in this
area.
When working on the pneumatic system there is a risk that compressed air escapes
abruptly and causes 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 depressurized and
vented before maintenance work.
