Ames Infrastructure Modernization (AIM) Project Appendix F – Safety Requirements and Deliverables

This appendix is not intended to be a comprehensive list. Additional documentation and requirements may arise as the project progresses.

1. Per DOE policy 851 Worker Protection Plan, Ames Laboratory contractors and subcontractors must demonstrate compliance with ACGIH TLVs, typically by industrial hygiene monitoring or objective third-party data.

2. All documentation must be available to Ames Laboratory upon request including, but not limited to:

training records, medical clearance, SOPs, and SDSs shall be provided in conjunction with the hazard evaluation and hazard management statements.

3. Copies of SDS for all chemicals, compounds, coatings, paints, etc. which will be brought on-site must be submitted in conjunction with the hazard evaluation documentation, or as soon as it is determined it will be used.

4. Contractors may encounter mercury compounds while working in laboratory space, elemental mercury when removing drain traps, or mercury vapor via broken fluorescent lamps.

5. Contractors/Subcontractors are not to access interstitial spaces due to potential contamination (beryllium, radiological, asbestos, etc. concerns).

6. Asbestos hazards or Potential Asbestos Containing Materials (PACM) will be identified by Ames Lab and mitigated by Ames Lab or a certified asbestos abatement contractor prior to work being performed by subcontractor.

7. Beryllium will be identified by Ames Lab and mitigated by Ames Lab prior to work being performed by subcontractor.

8. Lead will be identified by Ames Lab and mitigated by Ames Lab or a certified abatement contractor prior to work being performed by subcontractor.

9. Due to Legacy Radiation in the Ames Lab complex, no making penetrations in walls and no entering of spaces marked with Radiation Contamination will be allowed by any personnel unless reviewed and approved by Health Physicist Group, and other supervisory staff as required.

10. Crystalline Silica Exposures- Note that the Department of Energy requires that their contractors comply with the ACGIH TLV-TWA for respirable crystalline silica (RCS) as the exposure limit. This is a more stringent standard than the OSHA PEL (TLV=0.025 mg/m3 RCS; PEL=0.050 mg/m3 RCS). Work pause and the reassessment of work practices and personal protection with the Industrial Hygiene department are required if visible dust is observed in an operation.

11. Confined Spaces shall not be entered until there has been approval by Ames Laboratory ESH. All confined space entries will comply with CFR1910.146 and CFR1926 Subpart AA.

12. Identification of hazardous environments, including thermal stress such as extreme cold, heat or high humidity, shall be identified and accounted for in the work planning and control procedures. (Hazard Management Statements)

13. Activities that produce noise above 85 dBA using ACGIH standards shall be accounted for using engineering control, or using PPE such as earplugs, earmuffs or a combination of.

14. Traffic interruptions, foot traffic, vehicle traffic, etc., are prohibited without a Traffic Control Plan developed, reviewed and approved by Ames Laboratory and Iowa State Parking Division.

15. Lifting of objects over 50 pounds shall be completed using a two person lift or using a lifting device.

16. Oil quantities greater than 55 gallons are identified in the inventory required for Spill Prevention, Control, and Countermeasures (SPCC) plan (40 CFR 112)

17. All construction debris will be surveyed before being removed from site.

18. Electrical work must be performed only by qualified and approved electrical workers, with approved equipment and PPE, using the electrical safe work practices. An electrical assessment and work plan must be reviewed by AHJ before work can be performed.

19. Electrical work must be performed only by qualified and approved electrical workers, with approved equipment and PPE, using the electrical safe work practices

20. When an employee works in a confined or enclosed space (such as a manhole or vault) that contains exposed energized electrical conductors or circuit parts operating at 50 volts or more, or where an electrical hazard exists, the employer must provide, and the employee must use, protective shields, protective barriers, or insulating materials as necessary to avoid inadvertent contact with these parts and the effects of the electrical hazards.

21. Evaluate conditions to determine if any spaces are permit-required confined spaces.

22. Failure to understand what may lie behind a penetration may lead to contact and exposure to hazardous materials, electrical and other utilities. Contact may result in serious injury, death and/or property damage.

23. Wall/ceiling/floor penetrations necessitate a review of historical records, engineering plans, and as-built drawings that pertain to the area/location where the penetration is planned.

24. Non-destructive scanning should be performed.

25. All drilling or cutting work should use double insulated tools and wear appropriate insulating gloves in the event a hidden live feed is encountered

26. Field evaluate non-NRTL equipment or remove the non-NRTL equipment.

27. Application of a mechanical lockout device and a tag on an energy isolation by a LOTO authorized person in accordance with established procedures to control hazardous energies and prevent the equipment from being operated until the lockout device is removed.

28. Use ground fault circuit interrupters (GFCIs), especially where electrical equipment is used in or around wet or damp locations.

29. Make sure a generator is properly grounded and the grounding connections are tight. Consult the manufacturer’s instructions for proper grounding methods.

30. Never operate a portable generator inside a building or near windows and doors. It produces deadly carbon monoxide gas.

31. For any leading-edge work, barriers and warning flags must be installed during the duration of the project.

32. Scaffolding – must be erected by a trained competent person. That competent person is to be on-site any time scaffolding is in use. Certification must be made available when requested. All scaffolding usage will comply with 29 CFR part 1926, subpart L.

33. Usage of portable manlifts will comply with 29 CFR 1910 Subpart F.

34. All ladder usage will comply with 29 CFR 1910.23 or 29 CFR 1926.1053 as applicable. All ladders will be visually inspected daily prior to use.

35. PPE - Standard PPE must be worn by persons performing or assisting with performing the work. This includes but is not limited to safety glasses with side shields/safety goggles and hard hats where overhead hazards exist. Additional PPE may be required depending on hazard and mitigation requirements.

36. Respirators may be required where:

a. Airborne concentrations are elevated and ventilation/engineering controls cannot sufficiently reduce airborne exposures

b. Large surface areas and substantial hand work are involved

c. When respirators are used a respiratory protection program must be developed and implemented which complies with 29 CFR 1910.134 or CFR 1926.103 as applicable.

d. Note that the Department of Energy requires that their contractors comply with the ACGIH TLVs

(time-weighted averages, short-term exposure limits, ceilings).

37. Before performing hot work (torch use, grinding, cutting, etc.) coordination must be conducted with Ames

National Laboratory Plant Protection and a Hot Work Permit needs to be filled out and approved. A designated fire watch, with the properly rated fire extinguisher, must be in place during work and 60 minutes after the hot work has been completed. Proper ventilation/Air quality plan must be provided, reviewed, and approved before any hot work to be approved.

38. Hoisting & rigging - must be performed by a trained and certified persons. Employee training certification and inspection records must be made available when requested. Prior to any rigging or picking of equipment, contractor must supply a Pick Plan that must be reviewed and approved by Ames Laboratory ESH before work can be performed.
