EXECUTIVE SUMMARY

The Periodic Industrial Hygiene Survey of AV-8B Airframes (95552, 95774 and 95801) was conducted by Ms.

Alison Styron, Industrial Hygienist in November 2015. The purpose of this survey was to evaluate any changes to work processes or new work practices that have occurred since our previous survey in 2014.

The Branch’s facilities are located in bldg. 4224, 137 (Hangar 1) and 131(S). This division is comprised of airframe, sheet metal artisans and electricians.

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. This information is provided within this survey report. The FRC

East Division Secretaries will compile the registries and schedule the required medical surveillance physicals with the Naval Health Clinic Occupational Medicine Department.

Chromium VI Compliance: Based on existing exposure monitoring of sanding/grinding operations on AV-8B horizontal stabilizers in shop 95801, personnel are expected to exceed the Action Limit (AL) for hexavalent chromium and cadmium. Stabilizer sanding/grinding operations are conducted in the mezzanine walk-in booth in building 4224. Continued exposure monitoring of sanding/grinding operations on leading edge of horizontal stabilizers is required as well as enrollment of personnel in Cadmium, Chromic Acid/Hexavalent Chromium and

Respirator User Medical Surveillance.

Based on interviews with 95774 personnel and comparison to Similarly Exposed Group (SEG) data, sanding on AV-

8B intakes is likely to result in overexposures for chromium VI based on location of work and duration of activity.

Reportedly this work is conducted in shop 95774 and has not been mentioned in previous industrial hygiene survey interviews. (Reportedly, only 1 artisan performs this process). Until sufficient data is collected to rule out chromium VI overexposures during this process, 95774 sheet metal personnel shall adhere to the FRCE Cadmium

Written Compliance Program for Industrial Airframes Repair and Modification Division as well as 29 CFR

1910.1026. Highlights are identified in Tables 6 and 7 of this report. Based on task infrequency, enrollment in

ChromiumVI Medical Surveillance is not required.

Hearing Conservation Program: Interim Navy Medicine Hearing Conservation Program Guidance (dated 24 Apr

2014) identifies 85 decibels (dBA) as the interim Bureau of Medicine and Surgery (BUMED) OEL. Noise hazardous equipment and operations are identified in this survey including applicable Hearing Protective Device

(HPD) requirements. Operations with Sound Pressure Levels (SPLs) in excess of 85 dBA require single hearing protection. Operations with SPLs exceeding 96 dBA require double hearing protection. A noise hazardous equipment table is included in each shop assessment.

Respiratory Protection: Respiratory protection is worn by 95801 personnel conducting sanding/grinding on AV-

8B stabilizers. Until sufficient data is collected to rule out chromium VI overexposures during AV-8B intake sanding/grinding, 95774 sheet metal personnel conducting intake sanding shall wear respirator protection. Ensure all personnel that perform this work are enrolled in the Respiratory Protection Program and are trained and qualified for respirator use.

Eyewash Stations: Plumbed eyewash stations are located throughout the 4224, 137 and 131 work spaces. At the time of the walkthrough stations were accessible and appeared to be well maintained. Tags were attached reflecting recent testing and inspection. FRCE Safety office personnel and shop safety representatives manage eyewash stations, including placement, testing and maintenance.

Personal Protective Equipment (PPE): In general, personnel were observed wearing appropriate PPE during the walkthrough. However, the use of double hearing protection was not observed. Limited supplies of hearing protection and gloves were available for checkout in the area SE/tool room. Supervisory personnel and artisans expressed concerns about acquisition of these items. Ensure personnel are receiving PPE as needed.

Thermal Stress: Personnel are subject to thermal stress primarily during flightline operations. No thermal comfort issues were reported or noted during the workspace walkthroughs. 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.

This report reflects conditions and operations at AV-8B Airframes (95552, 95774 and 95801) during the survey period. Periodic Industrial Hygiene Surveys are required for work places by DODINST 6055.5 and OPNAVINST

5100.23G with a frequency of every year. In addition, changes in procedures, processes, or workload that may significantly alter personnel exposures require more frequent evaluations. Significant changes are defined as workplace modifications that require a change in recommended medical surveillance enrollment, personal protective equipment, or exposure control measures (ventilation, etc). Supervisory personnel should be encouraged to notify the FRCE Safety Office when significant changes occur. The next periodic industrial hygiene survey will be conducted in 2015.

-Ensure electricians 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.

-Personnel advise that extensive sanding and grinding operations are not conducted in this shop. If this status should change please contact the Naval Health Clinic Industrial Hygiene office for exposure reevaluation.

-Compressed air shall not be used to remove generated dust unless used in conjunction with a ventilation system designed to capture the generated dust cloud.

-Ensure personnel utilize HEPA vacuums during abrasive operations (sanding/grinding).

-Continue to ensure all HEPA vacuums are included in appropriate maintenance/HAZMAT programs.

-Personnel operating a rivet gun and personnel in immediate proximity shall utilize double hearing protection. Continue to ensure circumaural muffs are readily available to all personnel.

FINDINGS/RECOMMENDATIONS:

Finding: As noted in previous surveys, the Wilton dual sander and the Wilton bandsaw do not have containment systems for generated debris.

Recommendation: Containment systems should be attached for proper metal particulate capture.

Finding: Mold was observed on the ceiling surfaces on the adjacent hallway shared with MALS-14 personnel (reportedly due to a sprinkler system energization.)

Recommendation: Remove mold from affected surfaces.

Finding: Zinc chromate aerosol primer was on the AUL for shop 95552. Personnel advise they do not use zinc chromate aerosol primer. Substitutions for this product are available for use with brush applications.

Recommendations: Based on available substitutions for this product, this product should not be used and should be removed from the AUL.
