energized. Some wires remain energized even when the panel MASTER STOP or POWER ON/OFF switches are turned off. De-energize and lock out all electrical sources before opening enclosures. Close panel door before operating. Do not bypass or disconnect supervisory interlocks.
Supervisory devices have been installed in this fluid con- trol system to verify the system performs in the designed manner. Operating the fluid control system with any of these devices set at a point other than that which the operating manual specifies may expose personnel and equipment to serious hazards. WARNING Do not tamper with the controls and supervisory devices or attempt to alter their settings. Tampering with any controller may make the process unsafe. Operating with a controller other than the one which was designed and installed by Fives may expose personnel to serious hazards. The settings may only be changed with prior written consent from Fives, and only by a qualified technician.
B. Fuel Leaks Can Cause Fires
1. Fuel leaking from the fluid control system can ignite and burn uncontrollably.
2. Never operate the fluid control system if the fuel is leaking.
3. In case of a fuel leak, shut off the main fuel valve.
C. Pressurized gases can rupture pipes and hoses
Gasses under compression introduce hazards. Similar to a spring, compressed gas is stored energy. Should a break occur, piping or hoses may become a lethal whip. Should a rupture occur, failing equipment may be fragmented and the fragments propelled with great force. For these reasons, wear protective equipment, such as safety glasses and protective gloves when tending to this equipment.
IV. EMERGENCY SHUTDOWN
Familiarize yourself with all supervisory, shutdown, and start-up procedures before starting and operating this equipment. Control panels should be equipped with a large, red MASTER STOP button on the door of the control panel. Pressing this button should cause the automatic shutoff and blocking valves to close, stopping the flow of fuel gas. The Fluid Control System is equipped with a manual inlet valve. Closing this valve will shut off the flow of fuel to the control train. To prevent someone from restarting the system, close and lock out the manual fuel gas supply valves, and disconnect and lock out the main power supply.
Pressurized gases can leak. Leaking fuel can cause fires.
In case of a fuel leak, stop the fluid control system immediately. Before attempting to repair a leak, always consult the equipment maintenance manual and your plant maintenance procedures.
CAUTION Piping contains pressurized gases. Make sure piping and tubing is de-pressurized before repairs are at- tempted.
D. Moving parts can pinch
WARNING: Situations dangerous to personnel and property may exist with the operation and maintenance of any combustion equipment. The presence of fuels, oxidants, hot and cold combustion products, hot surfaces, electrical power in control and ignition circuits, etc., are inherent with any combustion application. Components in combustion systems may exceed 160°F (71°C) surface temperatures and present hot surface contact hazard. Fives North American Combustion, Inc. suggests the use of combustion systems that are in compliance with all Safety Codes, Standards, Regulations and Directives; and care in operation.
Pinching hazards exist on fluid control systems, due to the automatic and random operation of the valve actuators. Keep hands, body, and loose clothing away from moving parts.
