2. General Safety Information
Access
Ensure safe access and if necessary a safe working platform (suitably guarded)
before attempting to work on the product. Arrange suitable lifting gear if required.
Lighting
Ensure adequate lighting, particularly where detailed or intricate work is required.
Hazardous liquids or gases in the pipeline
Consider what is in the pipeline or what may have been in the pipeline at some previous time.
Consider; flammable materials, substances hazardous to health, extremes of temperature.
Hazardous environment around the product
Consider; explosion risk areas, lack of oxygen (e.g. tanks, pits), dangerous gases, extremes of
temperature, hot surfaces, fire hazard (e.g. during welding), excessive noise, moving machinery.
The system
Consider the effect on the complete system of the work proposed. Will any proposed action (e.g.
closing isolation valves, electrical isolation) put any other part of the system or any personnel at
risk? Dangers might include isolation of vents or protective devices or the rendering ineffective
of controls or alarms. Ensure isolation valves are turned on and off in a gradual way to avoid
system shocks.
Pressure systems
Ensure that any pressure is isolated and safely vented to atmospheric pressure.
Consider double isolation (double block and bleed) and the locking or labeling of closed valves.
Do not assume that the system has depressurized even when the pressure gauge indicates zero.
Temperature
Allow time for temperature to normalize after isolation to avoid danger of burns.
Tools and consumables
Before starting work ensure that you have suitable tools and/or consumables available. Use only
genuine Spirax Sarco replacement parts.
Tools and consumables
Before starting work ensure that you have suitable tools and/or consumables available. Use only
genuine Spirax Sarco replacement parts.
Protective clothing
Consider whether any protective clothing required by yourself and / or others in the vicinity to
protect against the hazards of, for example, chemicals, high / low temperature, noise, falling
objects, and dangers to eyes and face.
Permits to work
All work must be carried out or be supervised by a suitably competent person. Post 'warning
notices' if necessary.
Electrical works
Before starting work study the wiring diagram and wiring instructions, and check any special
requirements. Consider special emphasis on primary and phase source, local isolation of the
major systems, fuse requirements, grounding, special cables, cable entries and electrical voltage
selection.
Commissioning
After installation or maintenance, ensure that the system is working properly.
Perform tests on all alarms and protective devices.
Storage
Equipment and materials shall be stored in a proper place and securely.
