Table A-1 Potential Hazards and Recommended Controls Potential hazards Recommended Controls Chemical exposure The minimum level of proper PPE during activities is Level D. This level is considered adequate to protea individuals from exposure to petroleum hydrocarbon constituents. Air monitoring will be performed with an OVM or equivalent to monitor the air quality in and around the work zone. Back injury There are several heavy pieces of equipment anticipated for this project that would require lifting and possible back injuries. Use proper lifting techniques,specialized lifting,and automated equipment (i.e.,vacuum bailing and 2 person teams when necessary). Proper lifting techniques may also vary with task. Therefore,these techniques will also be addressed in the daily site safety briefings. Noise Heavy equipment is anticipated for this project (i.e.,drilling rig and backhoe),such that hearing protection may be necessary. In general,use hearing protection whenever the noise levels are such that conversation is impaired without raising the voice level. Drum handling Drums may be used to store soil or water as a result of drilling or excavation operations. Utilize appropriate drum handling equipment (dollies,lift gates,etc) and avoid manual lifting of filled or partially filled drums. Migration of A work zone will be delineated before start of work. An area within the work zone will be contamination established for decontamination prior to exiting the Site. The decontamination area must be away from the actual working area. Exposure to potentially Level D PPE is the minimum level required for this project. All personnel will don the contaminated soil/water appropriate level of PPE upon entering the work area and then use proper decontamination procedures before exiting the work zone. Workers will exit the work zone before eating. Slips,trips and falls The proper footwear for this project will include steel-toed boots upon entering the work zone. Wear proper footwear and anticipate footing hazards (i.e.,steep slopes,potholes,and uneven surfaces). Utilities/electrical Have all utilities (underground and overhead)located and documented prior to the initiation drilling or excavation activities. Maintain a minimum distance of 20 feet clearance between any energized line and any part of a drill rig, boom,or other piece of equipment at all times. This in compliance with a high-voltage line of 37 kv or less. If voltage is between 37 kv and 55 kv,then maintain a minimum distance of 27 feet. If voltage is between 55 kv and 100 kv,then maintain a minimum distance of 42 feet (8 CCR Division 1, Chapter 4, Subchapter 5 Group 2 Article 37 Section 2946 Trenching No Brown and Caldwell employee shall enter any trench or excavation that is five (5) feet or greater unless a protective system is provided. Protective systems include sloping or benching, shoring, or shielding. Also a method of access and egress must be provided and must be within 25 lateral feet of the employee. A competent person should inspect all excavations at least daily and as conditions change to determine the integrity of the protective systems. Some excavations may be considered a confined space especially if there is an actual hazardous atmosphere or reason to believe there may potentially be a hazardous atmosphere.Any trench or excavation that falls under these conditions must NOT be entered until they have been evaluated according to the confined space entry regulations. Heavy equipment Drilling and excavating equipment maybe necessary for this project. Personnel communication and wearing proper PPE during work activities is essential for the protection of workers at the site. See the Trenching,Drilling and Heavy Equipment SOPS forspecifics. The competent person for trenching will be the on-site SSO.
