All individuals who use or service this control train must recognize that hazards exist. Hazards also exist in the associated combustion system beyond the boundaries of this control train.
C. Operating precautions
1. Only trained, experienced operators should be allowed to operate this system. 2. Operate the system only after thoroughly studying the instructions. 3. Never operate the control system without all supervisory devices operating properly. 4. Never operate the fluid control system if fuel is leaking. 5. No open flames, smoking, or sources of ignition are permit- ted near the fluid control system, to guard against fires caused by fuel leaks. D. Maintneance precautions 1. Lock out the pressure supply source of fuel gas and de- pressurize all piping and tubing before maintenance or repair to avoid the hazards of a release of pressure. 2. De-energize and lock out electrical circuits before attempting any repair or maintenance of electrical equipment to prevent electrical shock. 3. It is suggested that an OSHA prescribed hazardous work procedure be utilized when performing repairs or adjustments on the fuel gas train, such as: • Pressure testing. • All set-up, adjustment, troubleshooting, and electrical repair work. • Any work on or near equipment or piping where pressure may still exist or be trapped.

Any time service is being performed, electrical lockout/tagout procedures should be observed. More than one discon- nect may be required to safety lock out any enclosure.
III. FLUID CONTROL SYSTEM HAZARDS A. Electric Shock Can Kil l
Electricity is present at many different points throughout the fluid control system. Improper use of electrical devices or attempting to service equipment without first disconnecting the electric power source can lead to electrical shock.
6. All main fuel manual shut-off valves should be closed when servicing the electrical system.
The Fives North American Combustion, Inc. fluid control system is an industrial heating process fuel shut-off and control system. By taking proper precautions and following recommended procedures, the fluid control system can be operated safely. II. HAZARD RECOGNITION
