1.2 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.

1.3 Lighting

Ensure adequate lighting, particularly where detailed or intricate work is required.

1.4  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.

1.5  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.

1.6  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.

1.7  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 labelling of 
closed valves. Do not assume that the system has depressurised even when the 
pressure   gauge   indicates    zero.

1.8 Temperature

Allow time for temperature to normalise after isolation to avoid the danger of burns and 

consider whether protective clothing (including safety glasses) is required.

Viton 'O' ring:

If  the  Viton  'O'  ring  has  been  subjected  to  a  temperature  approaching  315°C  (599°F) 

or higher, it may have decomposed and formed hydrofluoric acid. Avoid skin contact 

and  inhalation  of  any  fumes  as  the  acid  will  cause  deep  skin  burns  and  damage  the 

respiratory system.

1.9  Tools and consumables

Before starting work ensure that you have suitable tools and /or consumables 
available. Use only genuine Spirax Sarco replacement parts.

1.10  Protective clothing

Consider whether you and / or others in the vicinity require any protective clothing 
to protect against the hazards of, for example, chemicals, high / low temperature, 
radiation, noise, falling objects, and dangers to eyes  and  face.
