TK12 GROUT FAILED COILS 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. The vendor supplied grout hoppers may be refilled as needed to accomplish this work scope.
2.3. Encapsulated Lead Blankets will be utilized to minimize worker exposure to open riser conditions.
2.4. Utilize fire retardant materials (plastic, wood, etc.) to support the work tasks, do not store combustibles required for the job near ignition sources, and do not allow job waste to accumulate on or near tank top.
2.5. Portable eyewash units with rinse wands shall be positioned, readily available, in the immediate work area, with an unobstructed travel path, for each potentially exposed employee, 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. Crane activity will be required for the placement Supersack Grout bags and tote placement/removal. This activity will be repeated as required for duration of work scope. REF: Assoc. Ordinary Lift (HLWM-16004) and Critical Lift (HLW-CL-2014-00094) for rigging equipment.
2.7. In the event of a grout material spill: Contact the control room, Stabilize the work area and Notify the LWGS of the event and that a time-out has been taken. A dedicated individual shall be identified for spill response.
2.8. Utilize buckets/kiddie pools/witches hats for catch containment at line break locations. Skid pans will be utilized for staging catch containment and for pigging activities. Use HEPA vacuum to clean tools, materials and reusable PPE contaminated with silica-bearing dusts.
2.9. Coppus with Hepa will be required (in close proximity to line break locations) for all line breaks associated with coil grouting activities Template R0.V15 - 12/03/2014 Page 2 of 12
