APPENDIX E - SAFETY REQUIREMENTS AND DELIVERABLES

1. All documentation must be available to Ames Laboratory upon request including, but not limited to: training records, medical clearance, SOPs, and SDSs. These shall be provided in conjunction with the hazard evaluation and hazard management statements.

2. 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.

3. 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.

a. Very short duration hole drilling tasks which are incidental to primary work: the 8-hour

TWA exposure can reasonably be anticipated to remain under 0.025 mg/m3 where 1) the worker uses hand-held drills; 2) the duration of exposure is 15 minutes or less; and

3) there is no other RCS exposure for the remainder of the shift.

b. Tasks that may create RCS exposures at or above 0.025 mg/m3 as an 8-hour TWA under reasonably foreseeable conditions: the use of engineering control methods found in OSHA Table 1 is required. Respiratory protection must be used along with engineering control methods. Respirator use must be fully OSHA compliant, including a written respiratory protection program, medical surveillance, and respirator fit testing. “AL- Min”, shown below for handheld drills, is the Ames Laboratory-specific minimum requirements for respiratory protection. “AL-Min” criteria for additional tasks are listed in the Ames Laboratory’s Respirable Crystalline Silica Exposure Control Plan.

Construction Task or Equipment Operation

Engineering and Work Practice Control Methods

Required Respiratory Protection ≤ 4 hours/shift > 4 hours/shift

Handheld and stand-mounted drills (including impact and rotary hammer drills)

Use drill equipped with commercially available shroud or cowling with dust collection system.

Operate and maintain tool in accordance with manufacturer's instructions to minimize dust emissions.

Dust collector must provide the air flow recommended by the tool manufacturer, or greater, and have a filter with 99% or greater efficiency and a filter-cleaning mechanism.

Use a HEPA-filtered vacuum when cleaning holes.

AL-Min: Half Face negative pressure respirator with P100 cartridges

AL-Min: Half Face negative pressure respirator with P100 cartridges

4. Additional engineering controls such as portable ventilation units, use of critical barriers between the work area and adjacent indoor spaces, or HEPA vacuums may be requested by

Ames Laboratory personnel to mitigate any additional hazards or safety concerns that develop as the project progresses.

5. Hearing protection must be used when noise exposure is at or above 85 dBA (8-hour time-weighted average and ACGIH 3 dBA exchange rate). Please note that OSHA uses an exchange rate of 5 dBA—past noise assessments or noise guidelines provided with equipment may not adequately reflect this difference.

6. Copies of SDS for all chemicals, compounds, paints, solvents, 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.

7. Ergonomic concerns including lifting, pushing, pulling, hand and full body vibration shall be addressed in the hazard management statements along with the SOPs describing any equipment, equipment modifications, or PPE (Personal Protective Equipment) that may be used to mitigate such hazards.

8. Before performing hot work (torch use, grinding, cutting, etc.) coordination must be conducted with Ames Laboratory Guardroom. A designated fire watch must be in place during work and 60 minutes after the hot work has been completed.

9. PPE - Standard PPE must be worn by the contractors. 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.

10. All ladder usage will comply with 29 CFR 1910.23. All ladders will be visually inspected daily prior to use.

11. All power tools and extension cords must be inspected each day prior to use.

12. The following electrical standards shall apply to this Agreement:

1. All electrical work performed at the Laboratory shall be executed per the 2017 National Electrical Code (NFPA 70) and 2015 Standard for Electrical Safety in the Workplace

(NFPA 70E).

2. Subcontractor shall ensure each Subcontractor worker exposed to voltages greater than 50 volts has received 2017 NFPA 70 and 2015 NFPA 70E code update training before any working performing work under this Agreement and maintain appropriate written documentation evidencing the training. The subcontractor shall provide copies of this documentation to the Laboratory Technical Representative and Laboratory Procurement Official immediately upon request. Such appropriate documentation may include a copy of the card issued to the worker or certification issued to the worker from the authorized certification agency.

13. Contractors/Subcontractors are not to access interstitial spaces due to potential contamination

(beryllium, radiological, asbestos, etc. concerns).

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