TABLE ES-512-1 . CALIFORNIA EXCAVATION CHECKLIST 1) Prior to beginning an excavation, the location of all underground utilities and other underground hazards shall be determined. 2) A hazard assessment shall be conducted by a qualified person to evaluate the potential exposure to employees who may work in or around the excavation. 3) The excavation shall also be inspected by a qualified person after each rain or other hazard-increasing event to evaluate the potential hazards from slides or cave-ins. 4) Anytime an employee enters an excavation 5 feet or greater in depth, that employee must be protected by a system of shoring, sloping, benching, or alternative means as per the four options outlined above. 5) The conditions in #4 above will also require the employer to obtain the necessary excavation permit from Cal-OSHA. Two types of permits are available; (1) $50 per excavation type, (2) $100 annual permit for entire state. In order to obtain either permit, the employer must fill out the application form, provide Cal-OSHA with the employer's Accident Prevention Program, and pay • the fee. This must be conducted every time for the $50 permit. The $100 permit has a requirement that the employer contact the closest Regional Cal-OSHA office of the up-coming excavation, protection system utilized, date, located, etc. 6) Excavated materials shall be prevented from falling back into the excavation. Spoils should be placed no closer than 2 feet from the edge of the excavation. 7) Work which is conducted within the excavation should be under the direct supervision of a qualified person who is capable of modifying the shoring or sloping system. 8) A convenient and safe means of egress shall be provided for employees working within an excavation 4 feet deep or greater. This may consist of a stairway, ladder, or ramp located within 25 feet of lateral travel. 9) Any employee working in the vicinity of an excavator or other equipment shall not be in a position where that employee might fall into contact with the moving parts of that equipment. Employees shall also be wearing a reflective vest. 10) An adequate means of water drainage shall be implemented to reduce the likelihood of run-off entering the excavation. This shall hold true during the rainy season. If the accumulation of water could pose a hazard to employees, the • situation should be controlled prior to resumption of operations. 7
