7.0 HAZARD REDUCTION 7.1 GENERAL PROCEDURES Underground utilities will be located and identified prior to any operation; power lines and pipelines will be shut down, locked out, and tagged, as appropriate. Excavation, handling, stockpiling, and backfilling will not be conducted whenever the average wind speed is greater than 15 miles per hour (mph), or when the wind speed instantaneously exceeds 25 mph. During excavation, handling, stockpiling, and backfilling, the working areas, excavated material, and unpaved roadways will be watered down (if necessary) until the surface is moist, and maintained in a moist condition to minimize dust. Access and egress ramps shall be designed by a qualified soils engineer, and maintained in areas of excavation or trenching greater than 4 feet in depth. The ramps will be positioned so that no more than 25 feet of lateral travel is necessary to access them. The stability of adjacent structures must be determined prior to entering a trench or excavation greater than 4 feet in depth. Workers shall not be permitted underneath loads handled by excavation or loading equipment. Barriers shall be constructed to keep equipment and personnel away from the edge of the excavation. No confined space entry is anticipated during the course of these operations. However, if such a situation is encountered, workers are prohibited from entering confined spaces until the company plan dealing with confined spaces is implemented. 7.2 SAFETY INSPECTIONS Walk-through safety inspections of the work area will be conducted daily before the start of work and as conditions change. The results of these surveys will be communicated to the work crews during regularly scheduled "tailgate" safety meetings. The safety procedures and the day's planned operations will be discussed at these sessions. 7.3 ENVIRONMENTAL CONTROLS In the event that CGI readings anywhere on the site exceed 10 percent of the LEL, work will be suspended, monitoring will be continued as necessary to isolate the area of concern, and any or all of the following environmental controls will be implemented as appropriate: 1. Vapors from pooled petroleum product will be suppressed(if necessary)by spraying with foam, appropriate chemical suppressant, or carbon dioxide in gas form or dry ice. 2. Air movers will be used to ventilate the areas of concentration to below 10 percent LEL.
