PEI/RP1200-17 <br />WARNING: FIRE HAZARD <br />• Extinguish all smoking materials and <br />open flames. <br />• Do not start or operate vehicles. <br />• Do not operate electric power tools in <br />classified areas. <br />• Do not wear clothing that can generate <br />static charges. <br />• Discharge personal static by touching a <br />grounded metallic object before enter- <br />ing a classified area. <br />• Remove from service any tank system <br />or dispenser that Is leaking fuel or <br />vapor. <br />Observe the following precautions when working in a <br />classified area or in any area where fuel vapors may be <br />present, <br />• Open flames from matches or cigarette lighters, burn- <br />ing cigarettes, cigars or pipes can ignite fuel vapors <br />and should never be allowed in the vicinity of fuel <br />dispensing equipment or open containment sumps. <br />Sparks from vehicle ignition systems, starting the <br />vehicle, using the battery or from AC -powered tools <br />and devices, such as work lights or flashlights, can <br />ignite fuel vapors. Use explosion -proof equipment or <br />non -sparking tools when working in areas where fuel <br />vapors may be present. <br />Static electricity generated by friction on articles <br />of clothing or vehicle upholstery can cause a spark <br />sufficient to ignite fuel vapors. Wear clothing that <br />does not accumulate static charges. Individuals should <br />discharge static electricity by touching a grounded <br />metallic object well outside a classified area before <br />reaching into a space wherever flammable vapors may <br />be present. <br />• Be familiar with the location and operation of <br />appropriate fire extinguishers or fire suppression <br />systems at the facility before beginning any inspection, <br />test or maintenance task. <br />• A UST system component or dispenser that is leaking <br />fuel or vapor should not remain in service. If a leak is <br />discovered, deactivate the system or component, label <br />it "Out of Service" and notify the appropriate person. <br />3.5 People Hazards. Other personnel present at a <br />facility may cause significant hazards. Customers operat- <br />0 peLorg <br />ing vehicles, facility managers or operators who re-ener- <br />gize electrical circuits that have been turned off, or clerks <br />who authorize sales at dispensers that are being serviced <br />are hazards that must be anticipated and addressed. <br />Always advise personnel in charge of point-of-sale <br />systems and the facility management of work to be done. <br />Take note of traffic patterns. Note the activities of any <br />other workers at the facility and discuss with them ways <br />of minimizing or eliminating any hazards that may be <br />presented by their activities. <br />Use traffic barriers, PPE, lock-out/tagout procedures, <br />fuel shutoff valves and pump electrical disconnects as <br />necessary to ensure safety during dispenser and tank <br />system inspection, testing and maintenance activities. <br />3.6 Test Equipment. Use equipment intended for test- <br />ing spill, overfill, leak detection and secondary contain- <br />ment equipment. <br />For tests that impose a vacuum on a containment volume <br />or interstitial space, use only an air -operated vacuum <br />source or a vacuum pump powered by an explosion - <br />proof motor. Vacuum pumps with electric motors that <br />are not explosion -proof may ignite flammable vapors. If <br />a portable air compressor is used, it should be located at <br />least 20 feet away from the venturi-eductor or outside any <br />Class I, Division I area. <br />3.7 Confined Space Entry. UST system containment <br />sumps may be large enough to present hazards associated <br />with confined space entry. Refer to OSHA 1910.146 for <br />further guidance on confined space entry procedures. <br />3.8 Use of Water Versus Product for Testing. Do <br />not use gasoline, gasoline/ethanol blends, diesel fuel or <br />other stored liquids to test the integrity of spill buck- <br />ets and containment sump walls. Use water or other <br />approved monitoring liquid for tests requiring a test liq- <br />uid. A release of product from a leaking system presents <br />a safety hazard and could cause environmental damage. <br />Follow the guidelines in Section 6.7 for proper disposal <br />of water used in testing. <br />3.9 Responding to Spills. Spills may occur during <br />maintenance, testing or repair activities. Follow the spill <br />response procedure specified by the facility owner or <br />operator. A spill kit should be readily available at the <br />facility. <br />Avoid igniting spilled fuel. Immediately remove people <br />from the area and verify that no open flames or other <br />ignition sources are in the area of the spill. Do not allow <br />the starting of vehicles in the area. <br />
