Safe operation of these products can only be guaranteed if they are properly installed,
commissioned, used and maintained by qualified personnel (see Section 1.11) in compliance
with the operating instructions. General installation and safety instructions for pipeline and plant
construction, as well as the proper use of tools and safety equipment must also be complied with.
Safety note - Handling precautions
PTFE
Within its working temperature range PTFE is a completely inert material, but when heated
to its sintering temperature it gives rise to gaseous decomposition products or fumes which
can produce unpleasant effects if inhaled. The inhalation of these fumes is easily prevented
by applying local exhaust ventilation to atmosphere as near to their source as possible.
Smoking should be prohibited in workshops where PTFE is handled because tobacco
contaminated with PTFE will during burning give rise to polymer fumes. It is therefore
important to avoid contamination of clothing, especially the pockets, with PTFE and to
maintain a reasonable standard or personal cleanliness by washing hands and removing any
PTFE particles lodged under the fingernails.
1.1 Intended use
Referring to the Installation and Maintenance Instructions, name-plate and Technical Information
Sheet, check that the product is suitable for the intended use/application.
The products listed on pages 4 to 10 comply with the requirements of the European Pressure
Equipment Directive (PED), carry the mark when so required and fall within the Pressure
Equipment Directive categories stated.
i) The products have been specifically designed for use with liquids and gases which are in
Groups 1 and 2 of the above mentioned Pressure Equipment Directive.The products’ use on
other fluids may be possible but, if this is contemplated, Spirax Sarco should be contacted to
confirm the suitability of the product for the application being considered.
ii) Check material suitability, pressure and temperature and their maximum and minimum values.
If the maximum operating limits of the product are lower than those of the system in which it
is being fitted, or if malfunction of the product could result in a dangerous overpressure or
overtemperature occurrence, ensure a safety device is included in the system to prevent such
over-limit situations.
iii) Determine the correct installation situation and direction of fluid flow.
iv) Spirax Sarco products are not intended to withstand external stresses that may be induced by
any system to which they are fitted. It is the responsibility of the installer to consider these
stresses and take adequate precautions to minimise them.
v) Remove protection covers from all connections and protective film from all name-plates, where
appropriate, before installation on steam or other high temperature applications.

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.

IM-S24-42 CTLS Issue 10

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.
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 tobacco 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 538 °C (1 000 °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.
1.15 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. However, if
the valve is fitted with a Viton or PTFE seat, special care must be taken to avoid potential health
hazards associated with decomposition/burning of these seats.
PTFE:
- Can only be disposed of by approved methods, not incineration.
- Keep PTFE waste in a separate container, do not mix it with other rubbish, and consign it to
a landfill site.
1.16 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
precautions to be taken due to contamination residues or mechanical damage which may present a
health, safety or environmental risk. This information must be provided in writing including Health
and Safety data sheets relating to any substances identified as hazardous or potentially hazardous.
1.17 Working safely with cast iron products on steam
Cast iron products are commonly found on steam and
condensate systems. If installed correctly using good steam
engineering practices, it is perfectly safe. However, because
of its mechanical properties, it is less forgiving compared
to other materials such as SG iron or carbon steel. The
following are the good engineering practices required to
prevent waterhammer and ensure safe working conditions
on a steam system.
Safe Handling
Cast Iron is a brittle material. If the product is dropped during
installation and there is any risk of damage the product should
not be used unless it is fully inspected and pressure tested by
the manufacturer.
