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.
1.1 Intended use
Referring to the Installation and Maintenance Instructions, product markings and Technical
Information Sheet, check that the product is suitable for the intended use/application. The FTC62
and FTS62 comply with the requirements of the Pressure Equipment Directive (PED).
It should be noted that products within this category are required by the Directive to carry the mark.

i) These products have been specifically designed for use on steam, air or condensate/water, which
is in Group 2 of the above mentioned Pressure Equipment Directive (PED). 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. Safety information

IM-P179-15 CMGT Issue 3 3
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 opened and closed progressively 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.
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 may reach temperatures in excess of 425 °C (797 °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.
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.
