.(n PEURP1200-12 A UST system component or dispenser that is leaking fuel or vapor should not remain in service. If a leak is discovered, deactivate the system or component, label it "Out of Service" and notify the appropriate person. 3.5 People Hazards. Other personnel present at a facility may cause significant hazards. Customers operat- ing vehicles, facility managers or operators who re-ener- gize electrical circuits that have been turned off, or clerks who authorize sales at dispensers that are being serviced are hazards that must be anticipated and addressed. Always advise personnel in charge of point-of-sale sys- tems and the facility management of work to be done. Take note of traffic patterns. Note the activities of any other workers at the facility and discuss with them ways of minimizing or eliminating any hazards that may be presented by their activities. Use traffic barriers, personal protective equipment, lock- out/tagout procedures, fuel shutoff valves and pump electrical disconnects as necessary to ensure safety dur- ing dispenser and tank system inspection, testing and maintenance activities. 3.6 Test Equipment. Use equipment intended for test- ing spill, overfill, leak detection and secondary contain- ment equipment. For tests that impose a vacuum on a containment volume or interstitial space, use only an air-operated vacuum source or a vacuum pump powered by an explosion- proof motor. Vacuum pumps with electric motors that are not explosion-proof may ignite, flammable vapors. If a portable air compressor is used, it should be located at least 20 feet away from the venturi-eductor or outside any Class I, Division 1 area. 3.7 Confined Space Entry. UST system containment sumps may be large enough to present hazards associated with confined space entry. Refer to OSHA 1910.146 for further guidance on confined space entry procedures. 3.8 Use of Water Versus Product for Testing. Do not use gasoline, gasoline/ethanol blends, diesel fuel or other stored liquids to test the integrity of spill buck- ets and containment sump walls. Use water or other approved monitoring liquid for tests requiring a test liq- uid. A release of product from a leaking system presents a safety hazard and could cause environmental damage. Follow the guidelines in Section 6.7 for proper disposal of water used in testing. 3.9 Responding to Spills. Spills may occur during maintenance, testing or repair activities. Follow the spill response procedure specified by the facility owner or operator. A spill kit should be readily available at the facility. Avoid igniting spilled fuel. Immediately remove people from the area and verify that no open flames or other ignition sources are in the area of the spill. Do not allow the starting of vehicles in the area. Handle and dispose of used spill cleanup and sorbent materials according to instructions provided by the owner or operator of the facility. Do not store contaminated materials inside a building. The owner or operator should report any spill or discharg- es to the authority having jurisdiction (AHJ) as required by law. In some locations, reporting to more than one authority may be required. 3.10 Vehicle Hazards. Vehicles can present one of the more serious and common safety hazards while working at dispenser islands and areas where traffic is present at UST facilities. Drivers often are distracted and inattentive at UST facilities, and may not notice personnel conduct- ing testing, maintenance or repair activities. Take appropriate safety precautions prior to performing any inspection, testing or maintenance of overfill, leak detection and release prevention equipment. Workers should wear high-visibility safety vests while working in areas where vehicle traffic may be present. Use safety cones, barricades, warning signs and/or barrier tape to designate and isolate work areas. Take care not to place tools or equipment outside the designated area. Do not remove safety equipment, barricades or signs until all work is completed and equipment is ready to be returned to service. 4. TANK SECONDARY CONTAINMENT INTEGRITY TESTING 4.1 General. Double-walled tanks have interstitial spaces that can be tested for integrity. There are two methods for testing the integrity of tank secondary containment systems — dry and wet. Dry test methods use a partial vacuum to determine the integrity of the containment. To perform a wet test on an existing liquid-filled tank interstitial space, the liquid level in the 0 pei.org
