safety Information
safe operation of these products can be guaranteed only if they are properly installed, commissioned, used and maintained by qualified personnel (see point 11 on this document) 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. Intended use
Referring to the Installation and Maintenance Instructions, Nameplate and Technical Information Sheet, check that the product is suitable for the intended use/application. The products listedbelow comply with the requirements of the European Pressure Equipment Directive 97/23/EC and carry the CE and marks when so required. The products fall within the following Pressure Equipment Directive categories: II)

sible but, if this is contemplated, Spirax Sarco should be contacted to confirm the suitability of the product for the application being considered. 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. Determine the correct installationsituation and direction of fluid flow. 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. Remove protective covers from all connections before installation.

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 3. Lighting Ensure adequatelighting, particularly where detailed or intricate work is required. 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.

= -25°F to 220°F

The products have been specifically designed for use on steam, air and inertindustrial gases which are in Group 2 of the above mentioned Pressure Equipment Directive. The product’s use on other fluids may be pos-

 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. 6. The system Considerthe 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....
