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.
PTFE SEALS
If seals made from PTFE have been subjected to a temperature approaching 260°C (500°F)
or higher, they will give off toxic fumes, which if inhaled are likely to cause temporary
discomfort. It is essential for a no smoking rule to be enforced in all areas where PTFE is
stored, handled or processed as persons inhaling the fumes from burning tabacco
contaminated with PTFE particles can develop ‘polymer fume fever’.
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 of 350°C (662°F).
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.
