10.5 Supplementary Safety Information, Installation and Maintenance
Instructions for SA Temperature Control Systems:
Safe operation of these products can only be guaranteed if they are properly installed, commissioned, used and
maintained by qualified personnel 10.6 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.
10.5.1 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 below comply with the requirements of the
European Pressure Equipment Directive 97/23/EC and fall within category ‘SEP’. It should be noted that products within
this category are required by the directive now to carry the CE mark.
i) The products have been specifically designed for use on steam water and other non-hazardous fluids which are
in Group 2 of the above mentioned Pressure Equipment Directive. The products’ use on other fluids may be
possible but, if this is contemplated, Yokogawa 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 over temperature 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) Yokogawa 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
minimize them.
v) Remove protection covers from all connections before installation.
10.5.2 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.
10.5.3 Lighting
Ensure adequate lighting, particularly where detailed or intricate work is required
10.5.4 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.
10.5.5 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.
10.5.6 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.
