EXECUTIVE SUMMARY

The periodic Industrial Hygiene Survey of 95551 Field Team was conducted by Ms. Alison N. Styron, Industrial

Hygienist, in April 2015. The purpose of the survey was to evaluate any changes to work processes or work practices that have occurred since our previous survey in 2014. Specific hazard assessments in the following survey apply to 3 permanently assigned 95551 personnel (including a sheet metal artisan, a fiberglass/composite repair artisan and an electrician). Personnel on permanent assignment in New River are assessed by Camp Lejeune

Industrial Hygiene staff. Personnel on temporary field team assignments should adhere to their own “home” geographical shop industrial hygiene survey. In addition, personnel must follow safety and health guidelines of specific commands which they temporarily support.

The Field Team Branch performs depot level maintenance on aircraft at sites around the world and at sea. The field team has various artisans encompassing all aircraft trade skills to include, but not limited to: calibration, Non-

Destructive Inspection (NDI), machining, welding, tool making, electroplating, quality assurance, Examination and

Evaluation (E&E) and Planning and Estimation (P&E), as well as engine, airframe, composite, electrical and sheet metal repair.

Areas of particular concern or command interest are as follows:

Medical Surveillance: DODINST 6055.5 requires a registry of personnel occupationally exposed to hazardous chemicals and physical or biological agents to be developed for each workplace surveyed. This registry is used to ensure that each employee potentially exposed to a health hazard is enrolled in the appropriate medical surveillance program and is examined by an occupational health physician, physician assistant, audiologist, or other health care provider to detect any insidious or acute ill effects. The FRC East Division Secretaries will compile the registries and schedule the required medical surveillance physicals with the Naval Health Clinic Occupational Medicine

Department. Specific medical surveillance requirements applicable to those personnel permanently assigned to

FRCE Cherry Point Field Team are included in this report. Personnel temporarily assigned to Field Team activities shall adhere to medical surveillance requirements identified in their “home” geographical shop industrial hygiene survey. In addition, sheet metal artisans performing field team work greater than 30 days a year shall be enrolled in

Cadmium and Chromium VI Medical Surveillance Programs regardless of geographical (home) shop assignment.

Chromium VI/Cadmium Compliance: Based on Similar Exposure Group (SEG) overexposures, the 95551 sheet metal and composite repair artisans shall be enrolled in Chromic Acid/Chromium VI and Cadmium Medical

Surveillance Programs. In addition, based on the variability of component repair the sheet metal artisan is expected to exceed the PEL for cadmium. Compliance is managed by the FRC East Safety office. Continued Compliance

Exposure Monitoring (CEM) is required and is addressed in the shop assessment.

All temporarily assigned sheet metal artisans performing field team work greater than 30 days a year shall be enrolled in Cadmium and Chromium VI Medical Surveillance Programs regardless of geographical (home) shop assignment. Ensure that all temporarily assigned sheet metal artisans are enrolled in Chromic Acid/Chromium VI and Cadmium Medical Surveillance Programs and adhere to other mandates identified in CFR 1910.1026 and 1927.

Contact the FRCE Safety Office for assistance.

Respiratory Protection Program: The fiberglass composite artisan regularly wears respiratory protection for sanding/grinding operations. The sheet metal artisan is tasked with paint/corrosion removal operations on various components. North and 3M brand half and full face elastomeric respirators and Bullard hoods are available for use.

At the time of the walkthrough personnel seemed knowledgeable in respirator use, care, storage and maintenance.

Ensure all personnel temporarily assigned to field team activities are respirator trained and qualified. Contact the

FRCE Respiratory Protection Program Manager (RPPM) if there are questions regarding this program.

The 250C walk-in ventilated booth is equipped with a breathing panel. However, it has been out of calibration since

2010. It is recommended that the panel be calibrated to allow MALS-14 and 95551 personnel to utilize supplied air hoods.

Illumination: As noted in previous 95551 and MALS-14 IH surveys, lighting is deficient in 250C. Lighting surveys have been conducted documenting poor illumination levels. (One illumination survey is included in this report.) The deficient lighting introduces multiple safety concerns as personnel regularly operate various pieces of equipment conducting tasks that require sufficient lighting. It is recommended that the lights be upgraded to ensure illumination levels as recommended by the Illuminating Engineering Society can be achieved.

Thermal Stress: Permanent and temporarily assigned Field Team personnel are subject to thermal stress in a variety of workspaces. Ensure all personnel are trained in thermal stress recognition and prevention. Contact the

FRCE Safety Office if assistance is required.

Design Review: Industrial hygienists are required to actively participate in all facility planning, design, construction, and acceptance projects including both special and military construction projects to ensure appropriate hazard control techniques are applied. Please ensure all special projects, engineering designs, and purchasing contracts involving potential health hazards such as toxic materials, radiation, noise, or other health hazards are sent to the Industrial Hygiene Department for review.

Customer Satisfaction/Complaint Form: A customer satisfaction/complaint form is found in Appendix B of this report. Please complete this form as deemed necessary and return to the Naval Health Clinic Industrial Hygiene

Department Head.

Changes in Workplace Processes: This report reflects conditions and operations at this activity during the survey period. Please notify the Industrial Hygiene Department when significant changes occur in work center operations, chemical use, work processes, SOP revisions, or construction that may adversely affect worker health so review of documentation and evaluation may be conducted.

Periodic Industrial Hygiene Surveys are required for work places by DODINST 6055.5 and OPNAVINST 5100.23G with a frequency of every year for this shop. The next periodic industrial hygiene survey will be conducted in 2015.

-Ensure electrical trade personnel continue to receive regular training on the health hazards associated with lead soldering operations, per 29 CFR 1910.1025, Appendices A and B (OSHA lead standard). Although overexposures to lead are not anticipated, all personnel should be instructed to use good hygiene practices, e.g., washing hands thoroughly after conducting these operations to prevent accidental ingestion of lead.

FINDINGS/RECOMMENDATIONS:

Finding: As documented in previous MALS-14 Industrial Hygiene Surveys, the lighting in bldg. 250C is insufficient for tasks performed. A lighting assessment is included in this report (Table 5).

Recommendation: It is recommended that the lights be upgraded to ensure illumination levels as recommended by the

Illuminating Engineering Society can be achieved.

Finding: An electrical malfunction was noted during the 250C walkthrough. The power blinked 5 times in less than an hour in the sheet metal working area. Lighting is already poor in this workspace and after these blinks occur it takes several minutes for the bulbs to illuminate. Employees are often engaged in pneumatic and metal shaping/cutting equipment use in this space. Personnel reported that the power often blinks in the sheet metal working area while. (Note: Joint Safety Representatives were immediately notified of this concern).

Recommendation: Identify the cause of the electrical issue and correct.

Finding: As documented in previous surveys, the supplied air breathing panel is out of calibration for work in the walk-in booth in 250(C).

Recommendation: It is recommended that this panel be calibrated for service to allow both active duty and civilian personnel to utilize supplied air hoods. (A repair ticket is reportedly in the MAXIMO database for this discrepancy.)

SECTION IV – COMMENTS: (This booth is used for both MALS-14 paint operations and sanding operations conducted by

95551 personnel.

*Recommended velocity 75-125 for sanding operations per ACGIH Ventilation Manual, 27th Ed (chapter 3.) **Recommended velocity of 50 FPM of cross-sectional area when W X H is greater than 150 SQFT per ACGIH Ventilation Manual, 27th Ed.

(pages 13-134, 13-135, Figures VS-75-04 and VS-75-05). A minimum velocity of 60 FPM of cross-sectional area is recommended when painting using airless electrostatic or HVLP. Velocity measurements were taken and averaged. This ventilation system is adequate for the control of paint vapors, as well as, sanding operations. Ensure filters are changed at regular intervals to maximize performance.

SPECIFIC OSHA REGULATORY REQUIREMENTS

CADMIUM (29 CFR 1910.1027) CHROMIUM VI (29 CFR 1910.1026)

1910.1027 (c) Permissible Exposure Limit (PEL). The employer shall assure that no employee is exposed to an airborne concentration of cadmium in excess of five micrograms per cubic meter of air (5 ug/m3), calculated as an eight-hour-time-weighted average exposure (TWA).

1910.1026 (c) Permissible exposure limit (PEL). The employer shall ensure that no employee is exposed to an airborne concentration of chromium (VI) in excess of five micrograms per cubic meter of air (5 ug/m3), calculated as an eight hour time weighted average (TWA).

1910.1027 (e) Regulated areas—(1) Establishment. The employer shall establish a regulated area wherever an employee’s exposure to airborne concentrations of cadmium is, or can reasonably be expected to be in excess of the permissible exposure limit (PEL).

1910.1026 (e) Regulated areas. (1) Establishment. The employer shall establish a regulated area wherever an employee’s exposure to airborne concentrations of chromium

(VI) is, or can reasonably be expected to be, in excess of the

PEL.

1910.1027 (f) Methods of compliance—(1) Compliance hierarchy. (i) Except as specified in paragraphs (f) (1) (ii), (iii), and (iv) of this section the employer shall implement engineering and work practice controls to reduce and maintain employee exposure to cadmium at or below the PEL, except to the extent that the employer can demonstrate that such controls are not feasible.

1910.1027 (f) (1) (iv) Wherever engineering and work practice controls are required and are not sufficient to reduce employee exposure to or below the PEL, or, where applicable, the

SECAL, the employer nonetheless shall implement such controls to reduce exposures to the lowest levels achievable.

The employer shall supplement such controls with respiratory protection that complies with the requirements of paragraph (g) of this section and the PEL.

1910.1027 (f) (1) (v) The employer shall not use employee rotation as a method of compliance.

1910.1027 (f) (2) Compliance Program. (i) Where the PEL is exceeded, the employer shall establish and implement a written compliance program to reduce employee exposure to or below the PEL by means of engineering and work practice controls, as required by paragraph (f) (1) of this section. To the extent that engineering and work practice controls cannot reduce exposures to or below the PEL, the employer shall include in the written compliance program the use of appropriate respiratory protection to achieve compliance with the PEL.

1910.1026 (f) Methods of compliance. (1) Engineering and work practice controls. (i) Except as permitted in paragraph

(f) (1) (ii) and (f) (1) (iii) of this section, the employer shall use engineering and work practice controls to reduce and maintain employee exposure to chromium (VI) to or below the PEL, unless the employer can demonstrate that such controls are not feasible. Wherever feasible engineering and work practice controls are not sufficient to reduce employee exposure to or below the PEL, the employer shall use them to reduce employee exposure to the lowest levels achievable, and shall supplement them by the use of respiratory protection that complies with the requirements of paragraph (g) of this section.

1910.1026 (f) (1) (2) Prohibition of rotation. The employer shall not rotate employees to different jobs to achieve compliance with the PEL.

1910.1027 (f) (1) (iii) The requirement to implement engineering and work practice controls to achieve the PEL or, where applicable, the SECAL does not apply where the employer demonstrates the following:

1910.1027 (f) (1) (iii) (A) The employee is only intermittently exposed; and

1910.1027 (f) (1) (iii) (B) The employee is not exposed above the PEL on 30 or more days per year (12 consecutive months).

1910.1026 (f) (1) (iii) Where the employer can demonstrate that a process or task does not result in any employee exposure to chromium (VI) above the PEL for 30 or more days per year

(12 consecutive months), the requirement to implement engineering and work practice controls to achieve the PEL does not apply to that process or task.
