PLACEMENT OF BULK FILL GROUT TANK 12 Rev: 0 2.0 Precautions and Limitations:
2.1. Workers shall perform Individual Hazard Analysis (IHA) for this task, which includes continual self-analysis of work scope, hazards and controls (reference Savannah River Site General Employee Basic Hazard Control Handbook).
2.2. Warning barricades are required for work areas to control unauthorized access to the work area, identify hazards associated with work, and prevent personnel contact with falling objects and moving parts of equipment.
2.3. If unexpected loss of ventilation or improper air flow occurs, place job in a safe condition, exit the area, and NOTIFY RCO FLM, PIC, and IH for path forward.
2.4. If problems or conditions are encountered that were not anticipated or covered under the AHA or associated permits, or the boundaries of the work need to be modified or changed as the job progresses, SUSPEND WORK, Notify supervision, and return the work package to the work coordinator or planner for required revisions.
2.5. Safety shower/eyewash equipment must be located in accessible locations that require no more than 10 seconds to reach. The safety shower/eyewash equipment shall be located on the same level as the hazard. Travel distance from the point of exposure to safety shower/eyewash equipment may not exceed 50 feet., where potential exposure to chemicals exists. Number of employees exposed at any given time should be limited. In case of exposure to eyes, eyewash for required immediate 15 minute flush. In case of exposure to skin or body, rinse wand for immediate flush of affected area then escort personnel to a plumbed unit to complete the 15 minute flush. Contaminated clothing to be removed immediately and exposed person to seek immediate medical attention.
2.6. In the event of a spill of grout material greater than 5 gallons out of secondary containment, CONTACT the Shift Manager for Direction 2.7. Personnel should not attempt to lift more than they are capable of lifting. If equipment is hard or awkward to handle, mechanical means should be used and/or additional personnel should perform the task. Proper lifting techniques should be used. Loads should be lifted with the legs instead of the back while twisting or bending at the waist should be avoided. Slickline weight: approx.
150lbs for a 10 foot pc. Tremie weight: approx. 30lbs for a 20 foot roll.
Care should be taken when moving or connecting slickline and riser tremie.
Mechanical assistance in the form of a grass hopper lifting tool will be used to position the sections of the slickline when possible. If field conditions will not allow the use of a grass hopper, friction clamps attached to a lifting bar with additional personnel will be used.
