4.0 GENERAL SAFETY <br /> 4.1 General Safety Introduction <br /> Operation of this facility entails physical hazards which can result in injuries. However,these risks can <br /> be reduced with the application of good safety practices. Basic safety principles and the hazards <br /> involved must be known by all personnel. An operator can ensure his own safety and that of his <br /> fellow workers if he will follow three steps in performing all work: <br /> 1. Know the hazards involved. <br /> 2. Take time to assemble the proper tools and safety equipment before starting work. <br /> 3. Take enough time to consider the hazards of performing a task before actually doing it. <br /> 4.2 Electrical Equipment <br /> Personnel are protected during normal operating duties from contact with electricity by the enclosed <br /> electrical control system. The control systems will remain safe if properly maintained and all doors, <br /> covers, and panel sides are kept securely closed. Personnel shall not per electrical maintenance <br /> after power has been connected. <br /> Shock hazards are present any time maintenance work is done on.electrical control panels. Hazards <br /> are also present when using electrically driven hand tools. Electrical maintenance work should be <br /> performed by a qualified electrician. <br /> Two conditions are necessary for an electrical accident. The body must be connected to a source of <br /> electrical energy, and must be grounded so that the energy passes through the body on its way to <br /> ground. Electricity kills by paralyzing the nervous system and stopping muscular action. Frequently, <br /> electricity may hit the breathing center at the base of the brain and interrupt the transmission of <br /> nervous impulses to the muscles responsible for breathing. In other cases,the electric current directly <br /> affects the heart, causing it to cease pumping blood. Death follows from lack of oxygen in the body. <br /> 4.3 Hearing Protection <br /> Noise can annoy, disrupt concentration,intetfere.with communication,lower.job performance and <br /> safety, and cause nausea,aural pain, and loss of hearing. Limits have been set by the U.S. Department <br /> of Labor under the Occupational Safety and Health Act. Permissible exposures are given in the <br /> following table: <br /> Hours of exposure Sound levels <br /> 8 85 <br /> 4 88. <br /> .2 91 <br /> 1 94 <br /> 1/2 97 <br /> 'Ceiling value,dBA <br /> Note: Sound decibels as measured on a standard level meter operating on the <br />— A-weighing network with slow meter response. <br /> D:\POMP\Stockton Yard PMP.doc <br />
