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 danger of burns.
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 any protective clothing is 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.
1.11 Permits to work
All work must be carried out or be supervised by a suitably competent person.
Installation and operating personnel should be trained in the correct use of the product according
to these instructions.
Where a formal 'permit to work' system is in force it must be complied with. Where there is no such
system, it is recommended that a responsible person should know what work is going on and, where
necessary, arrange to have an assistant whose primary responsibility is safety.
Post 'warning notices' if necessary.
1.12 Handling
Where the weight of the product exceeds 20 kg it is recommended that suitable lifting equipment
is used to prevent personal injury.
1.13 Residual hazards
In normal use the external surface of the product may be very hot. If used at the maximum permitted
operating conditions the surface temperature of some products may reach temperatures in excess
of 200 °C.
Many products are not self-draining. Take due care when dismantling or removing the product from
an installation (refer to Section 11, 'Maintenance').
