3. Personal Protective Equipment (PPE): Detail appropriate PPE requirements, evaluate current PPE availability, and document actual employee compliance.

3.3 Ventilation System Evaluation

Evaluate the effectiveness of all general and local exhaust ventilation systems even if they are not in active use during the survey. Note any inoperable or damaged systems.

Quantitative Performance Metrics:

Paint Spray Booths: Verify that average cross-sectional face velocity is maintained at 100 ± 20 feet per minute (fpm) in accordance with OSHA 29 CFR 1910.94 Table G-10 and ACGIH recommendations.

Local Exhaust / Welding Hoods: Verify a minimum capture or face velocity of ≥ 100 fpm.

Vehicle Tailpipe Slots/Hoses: Verify capture velocities achieve a minimum slot velocity of ≥ 150 fpm or duct transport velocity of ≥ 2,000 fpm.

Use smoke tubes or cool-burning smoke candles to analyze airflow patterns in spray paint and abrasive blasting booths. Describe these patterns and identify dead zones or eddies in the report.

Identify any potential for clean air intake contamination by recirculated exhaust.

3.4 Noise Dosimetry

Conduct personal noise dosimetry on at least ten (10) maintenance employees per facility who are most likely to experience high noise exposures.

Attachment 4: Sample Process Description

CSMS Spray Painting Operation The Paint Shop contains a large downdraft booth and is located adjacent to the vehicle maintenance bays in the “E” Wing of the CSMS. The dimensions of the booth are approximately 17.5' W x 40' L x 12.5' H.

Vehicle-sized swing-hinge doors are installed at each end of the booth, and four personnel egress doors are approximately 3’ W x 7’ H. Two full-time painters are assigned and report that at current workloads, they are required to paint for a duration of approximately four hours, 2 to 3 days per week.

Exhaust Ventilation: The average cross-sectional air velocity in large paint booths is recommended by OSHA 29 CFR 1910.94 Table G-10 to be between 75 and 125 feet per minute (fpm). The paint booth at the CSMS has an average cross-sectional velocity of 64 fpm, which does not meet the standard. Airflow is unevenly distributed across the booth. Smoke testing demonstrated that the ventilation system is only moderately effective at clear air replacement. Recommendation: The system should be serviced, balanced, and the filters replaced. Regular servicing and lubrication of belts and moving parts will extend the life of the equipment and ensure effective performance.

Booth Pressure: The booth relative to the adjacent workspace is under a slight negative pressure.

The ACGIH Ventilation Manual, Paragraph 13.75, notes that maintaining the paint booth under slight negative pressure reduces the potential of toxic paint vapors escaping the booth into adjacent work areas.

Pressure Gauge (Manometer): Manometers are installed on the booth supply and exhaust filter banks to show the pressure drop as required by OSHA 29 CFR 1910.94(c)(7)(iii)[b]. On the survey date, the manometers needed fluid, required zeroing, and were not marked with clear high/low operating indicators.

Sound Pressure Levels: A sound level meter was used to measure noise levels in the booth during spray painting. All levels were below the Army criterion threshold of 85 dBA and are presented in Appendix X.

Personal Protective Equipment (PPE): Personnel donned disposable coveralls (Tyvek), chemical-resistant gloves, and supplied-air respirators.

Emergency Equipment: An emergency eyewash and shower unit is provided adjacent to the paint mixing area. The unit was documented as inspected weekly and provided tepid flushing fluid as recommended by ANSI/ISEA Z358.1-2009.

Attachment 6: Determining the Noise Risk Assessment Code (RAC)

To assign a noise RAC for employee notifications on DA Form 4700:

38. Group Personnel: Define Similar Exposure Groups (SEGs) / Occupational Exposure Groups (OEGs) (e.g., Aircraft Mechanics, Ground Support, Machinists).

39. Calculate Statistical UTL: For SEGs/OEGs with six (6) or more personal dosimetry samples, calculate the Upper Tolerance Limit (UTL) (95% confidence level, 95th percentile). If the SEG contains fewer than 6 workers, use individual TWA-8 results.

40. Assign RAC: Determine the RAC based on the simplified table below:

Exposure Result (Individual TWA or SEG UTL)

< 10 Workers in SEG/OEG 10 or more Workers in SEG/OEG

< 82 dBA RAC 4 (Minor) RAC 3 (Moderate)

≥ 82 dBA RAC 3 (Moderate) RAC 2 (Serious)
