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.
