Ð Safety Valve; Ð Injury Prevention - Atlas Copco XA186 Dd Instruction Manual

6 Draining of condensate shall be performed regularly when vessel is in
use.
7 Installation, design and connections should not be changed.
8 Bolts of cover and flanges may not be used for extra fixation.
Safety valve
All adjustments or repairs are to be done by an authorized representative of
the valve supplier.
Following checks must be carried out:
1 A check of the opening of the lifting gear, 1 or 2 times a year. This can be
done by screwing the cap of the valve anti-clockwise.
2 A check of the set pressure once a year according to the local regulations,
if required. This check may not be done with the compressor supplying
the air pressure and must be carried out on a proper test bench.

NJURY PREVENTION
1 Stationary housing guards are provided on all rotating or reciprocating
parts not otherwise protected and which may be hazardous to personnel.
Machinery shall never be put into operation, when such guards have been
removed, before the guards are securely reinstalled.
2 Do not open electrical cabinets, cubicles or other equipment while voltage
is supplied. If such cannot be avoided, e.g. for measurements, tests or
adjustments, have the action carried out by a qualified electrician only,
with appropriate tools, and ascertain that the required bodily protection
against electrical hazards is applied.
3 Noise, even at reasonable levels, can cause irritation and disturbance
which, over a long period of time, may cause severe injuries to the
nervous system of human beings.
When the sound pressure level, at any point where personnel normally
has to attend, is:
below 70 dB(A): no action needs to be taken,
above 70 dB(A): noise-protective devices should be provided for people
continuously being present in the room,
below 85 dB(A): no action needs to be taken for occasional visitors
staying a limited time only,
above 85 dB(A): room to be classified as a noise-hazardous area and an
obvious warning shall be placed permanently at each
entrance to alert people entering the room, for even
relatively short times, about the need to wear ear
protectors,
above 95 dB(A): the warning(s) at the entrance(s) shall be completed
with the recommendation that also occasional visitors
shall wear ear protectors,
above 105 dB(A):special ear protectors that are adequate for this noise
level and the spectral composition of the noise shall be
provided and a special warning to that effect shall be
placed at each entrance.
4 Insulation or safety guards of parts the temperature of which can be in
excess of 80 ¡C (175 ¡F) and which may be accidentally touched by
personnel shall not be removed before the parts have cooled to room
temperature.
5 When hot parts have to be handled, e.g. shrink fitting, special heat-
resistant gloves shall be used and, if required, other body protection shall
be applied.
6 If the working process produces fumes, dust or vibration hazards, etc.,
take the necessary steps to eliminate the risk of personnel injury.
7 Before lifting machines, all loose parts which could be liable to fall down
shall be removed or secured; pivoting parts such as doors, drawbars, etc.
shall be safely immobilized.
8 To lift heavy parts, a hoist of ample capacity, tested and approved
according to local safety regulations, shall be used.
9 When lifting machinery or parts with one or more lifting eyes, only hooks
or shackles meeting local safety regulations shall be applied. Never shall
cables, chains or ropes be applied directly on or through lifting eyes.
Never allow sharp bends in lifting cables, chains or ropes.
10 Lifting hooks, eyes, shackles, etc. shall never be bent and shall only have
stress in line with their design load axis. The capacity of a lifting device
diminishes when the lifting force is applied at an angle to its load axis.

11 For maximum safety and efficiency of the lifting apparatus all lifting
members shall be applied as near to perpendicular as possible. If required,
a lifting beam shall be applied between hoist and load.
12 When heavy parts are being lifted with a hoist, it is strictly forbidden to
dwell or pass under the load or in the space which is liable to be hit if the
load or part of it should topple over or come loose. Never leave a load
hanging on a hoist. Lifting acceleration and retardation shall be kept
within safe limits.
13 A hoist has to be installed in such a way that the object will be lifted
perpendicular. If that is not possible, the necessary precautions must be
taken to prevent load-swinging, e.g. by using two hoists, each at
approximately the same angle not exceeding 30¡ from the vertical.
14 When using compressed air or inert gas to clean down equipment, do so
with caution and use the appropriate protection, at least safety glasses, for
the operator as well as for any bystander. Do not apply compressed air or
inert gas to your skin or direct an air or gas stream at people. Never use it
to clean dirt from your clothes.
15 Before blowing compressed air or inert gas through a hose, ensure that the
open end is held securely, so that it cannot whip and cause injury.
16 When washing parts in or with a cleaning solvent, provide the required
ventilation and use appropriate protection such as a breathing filter, safety
glasses, rubber apron and gloves, etc.
17 Safety shoes should be compulsory in any workshop and if there is a risk,
however small, of failing objects, wearing of a safety helmet should be
included.
18 If there is a risk of inhaling hazardous gases, fumes or dust, the
respiratory organs must be protected and, depending on the nature of the
hazard, so must the eyes and skin.
19 Remember that where there is visible dust, the finer, invisible particles
will almost certainly be present too; but the fact that no dust can be seen
is not a reliable indication that dangerous, invisible dust is not present in
the air.
20 When using cartridge type breathing filter equipment, ascertain that the
correct type of cartridge is used and that its useful service life is not
surpassed.
