MD 150 Renovation – Construction Phase 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, CFR 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 National Laboratory. If asbestos is positively identified, or is a PACM that could not be tested, a mitigation plan will be developed by subcontractor and Ames National Laboratory.

7. Beryllium hazards will be identified by Ames National Laboratory. If Beryllium contamination is positively identified, a mitigation plan will be developed by subcontractor and Ames National Laboratory.

8. Lead hazards will be identified by Ames National Laboratory. If Lead contamination is positively identified, a mitigation plan will be developed by subcontractor and Ames National Laboratory.

9. Radiation hazards will be identified by Ames National Laboratory. If Radiation contamination is positively identified, a mitigation plan will be developed by subcontractor and Ames National Laboratory.

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. Nuisance dust may be generated during work activities, if visible dust is observed, a reassessment of work practices and personal protection by Ames National Laboratory is required.

12. 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.

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. Subcontractor Affirmation Form needs to be completed and signed by all subcontractor’s and sub-tier subcontractor’s company representatives to acknowledge that all rules and regulations listed in the Terms and Conditions, along with any other safety related documents and or conversations, are being communicated and adhered to through all tiers of subcontractors. It is the responsibility of the subcontractor awarded the contract to make sure all sub-tier subcontractors are following all rules and regulations at all times, and enforce proper escalation protocols if rules and regulations are not being followed.

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

18. Electrical work must be performed, per NFPA 70E, 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. 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.

20. 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.

21. Non-destructive scanning should be performed.

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

23. 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.

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

25. 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.

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

27. A Fall Protection Program must be submitted and reviewed before any work is allowed to be performed in the proximity of floor openings, on elevated work platforms, or on scaffolds.

28. 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.

29. 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.

30. 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).

31. 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.

32. All machine guards must be installed to protect against rotating parts.

33. Potential pinch points shall be identified before work is to proceed. All parties are to be notified and given clear instructions on how to avoid being in or around pinch points before work is to be performed.

34. 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.
