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 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.

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 the Installation

and Maintenance 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

Manual handling of large and/or heavy products may present a risk of injury. Lifting, pushing,

pulling, carrying or supporting a load by bodily force can cause injury particularly to the back. You

are advised to assess the risks taking into account the task, the individual, the load and the

working environment and use the appropriate handling method depending on the circumstances

of the work being done.

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

over 500°C. Many products are not self-draining. Take due care when dismantling or removing

the product from an installation (refer to ‘Maintenance instructions’).

1.14 Freezing

Provision must be made to protect products which are not self-draining against frost damage in

environments where they may be exposed to temperatures below freezing point.

1.15 Safety information - Product specific

See the specific details relating to product in the following ‘Maintenance’ section.

1.16 Disposal

Unless otherwise stated in the Installation and Maintenance Instructions, this product is recyclable

and no ecological hazard is anticipated with its disposal providing due care is taken.

1.17 Returning products

Customers and stockists are reminded that under EC Health, Safety and Environment Law,

when returning products to Spirax Sarco they must provide information on any hazards and the
