PRODUCT SAFETY
Product Safety Information
General
- The following information is important in ensuring safety. It
must
be brought to the attention of personnel involved in the
selection of power transmission equipment, those responsible for the design of the machinery in which it is to be incorporated and those
involved in its installation, use and maintenance.
Our equipment will operate safely provided it is selected, installed, used and maintained properly. As with any power transmission
equipment
proper precautions must
be taken as indicated in the following paragraphs, to ensure safety.
Potential Hazards
- these are
not
necessarily listed in any order of severity as the degree of danger varies in individual circumstances.
It is important therefore that the list is studied in its entirety:-
1) Fire/Explosion
(a) Oil mists and vapour are generated within gear units. It is therefore dangerous to use naked lights in the proximity of gearbox
openings, due to the risk of fire or explosion.
(b) In the event of fire or serious overheating (over 300
o
C), certain materials (rubber, plastics, etc.) may decompose and produce
fumes. Care should be taken to avoid exposure to the fumes, and the remains of burned or overheated plastic/rubber materials
should be handled with rubber gloves.
2) Guards - Rotating shafts and couplings must be guarded to eliminate the possibility of physical contact or entanglement of clothing. It
should be of rigid construction and firmly secured.
3) Noise - High speed gearboxes and gearbox driven machinery may produce noise levels which are damaging to the hearing with
prolonged exposure. Ear defenders should be provided for personnel in these circumstances. Reference should be made to the
Department of Employment Code of Practice for reducing exposure of employed persons to noise.
4) Lifting - Where provided (on larger units) only the lifting points or eyebolts must be used for lifting operations (see maintenance manual
or general arrangement drawing for lifting point positions). Failure to use the lifting points provided may result in personal injury and/or
damage to the product or surrounding equipment. Keep clear of raised equipment.
5) Lubricants and Lubrication
(a) Prolonged contact with lubricants can be detrimental to the skin. The manufacturer's instruction must be followed when handling
lubricants.
(b) The lubrication status of the equipment must be checked before commissioning. Read and carry out all instructions on the lubricant
plate and in the installation and maintenance literature. Heed all warning tags. Failure to do so could result in mechanical damage
and in extreme cases risk of injury to personnel.
6) Electrical Equipment - Observe hazard warnings on electrical equipment and isolate power before working on the gearbox or
associated equipment, in order to prevent the machinery being started.
7) Installation, Maintenance and Storage
(a) In the event that equipment is to be held in storage, for a period exceeding 6 months, prior to installation or commissioning, we must
be consulted regarding special preservation requirements. Unless otherwise agreed, equipment must be stored in a building
protected from extremes of temperature and humidity to prevent deterioration.
The rotating components (gears and shafts) must be turned a few revolutions once a month (to prevent bearings brinelling).
(b) External gearbox components may be supplied with preservative materials applied, in the form of a "waxed" tape overwrap or wax
film preservative. Gloves should be worn when removing these materials. The former can be removed manually, the latter using
white spirit as a solvent.
Preservatives applied to the internal parts of the gear units do not require removal prior to operation.
(c) Installation must be performed in accordance with the manufacturer's instructions and be undertaken by suitably qualified
personnel.
(d) Before working on a gearbox or associated equipment, ensure that the load has been removed from the system to eliminate the
possibility of any movement of the machinery and isolate power supply. Where necessary, provide mechanical means to ensure
the machinery cannot move or rotate. Ensure removal of such devices after work is complete.
(e) Ensure the proper maintenance of gearboxes in operation. Use only the correct tools and our approved spare parts for repair and
maintenance. Consult the Maintenance Manual before dismantling or performing maintenance work.
8) Hot Surfaces and Lubricants
(a) During operation, gear units may become sufficiently hot to cause skin burns. Care must be taken to avoid accidental contact.
(b) After extended running the lubricant in gear units and lubrication systems may reach temperatures sufficient to cause burns. Allow
equipment to cool before servicing or performing adjustments.
9) Selection and Design
(a) Where gear units provide a backstop facility, ensure that back-up systems are provided if failure of the backstop device would
endanger personnel or result in damage.
(b) The driving and driven equipment must be correctly selected to ensure that the complete machinery installation will perform
satisfactorily, avoiding system critical speeds, system torsional vibration, etc.
(c) The equipment must not be operated in an environment or at speeds, powers, torques or with external loads beyond those for
which it was designed.
(d) As improvements in design are being made continually the contents of this catalogue are not to be regarded as binding in detail, and
drawings and capacities are subject to alterations without notice.
The above guidance is based on the current state of knowledge and our best assessment of the potential hazards in the operation of the
gear units.
Any further information or clarification required may be obtained by contacting our Application Engineers.
