Do not incinerate, puncture or attempt to remove the
center core valve, side safety valve or any other part
of an ether container.
1.8
Pressure vessels
Maintenance / installation requirements:
1
The vessel can be used as pressure vessel or as
separator and is designed to hold compressed air for
the following application:
- pressure vessel for compressor.
- medium AIR/OIL,
and operates as detailed on the data plate of the vessel:
- the maximum working pressure in psi,
2
The pressure vessel is only to be used for the
applications as specified above and in accordance
with the technical specifications. Safety reasons
prohibit any other applications.
3
National legislation requirements with respect to re-
inspection must be complied with.
4
No welding or heat treatment of any kind is permitted
to those vessel walls which are exposed to pressure.
5
The vessel is provided and may only be used with the
required safety equipment such as manometer,
overpressure control devices, safety valve, etc.
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.
1.9
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 lifting the ring.
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.
1.10
Injury 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 ºC (175 ºF) 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, 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, 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.
