EXECUTIVE SUMMARY

The Periodic Industrial Hygiene Survey of V-22 PMI/MOD (Shops 95101 and 95301) was conducted by Ms. Alison

Styron, Industrial Hygienist, in May 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.

This shop is located in bldg.137. 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 Programs: Primarily, personnel conduct minor sanding/grinding activities on the V-

22. However, larger scale corrosion removal operations are reportedly conducted approximately once a month.

Based on Similar Exposure Group (SEG) monitoring data, exposure monitoring of this operation was ordered.

Though results have not exceeded the Action Limit (AL) for chromium VI, additional exposure monitoring is necessary to adequately quantify exposures. Based on reported task infrequency, medical surveillance is not required, however, implementation of CFR 1910.1026 (Hexavalent Chromium) and the FRCE Cadmium Written

Compliance Program for Industrial Airframes Repair and Modification Division is mandated. Should personnel conduct this operation greater than 30 days a year, enrollment of personnel in Chromium VI medical surveillance is required as mandated by 1910.1026. Until sufficient data is obtained continued exposure monitoring is required. Contact the Naval Health Clinic Industrial Hygiene Department at 466-3362 to schedule continued monitoring of this operation.

Eyewash Stations: Plumbed eyewash stations are located throughout the Bldg. 137 hangar space. At the time of the walkthrough stations were accessible and appeared to be well maintained. Tags on bldg. 137 eyewashes were attached reflecting recent testing and inspection. FRCE Safety Personnel manage eyewash stations, including placement, testing and maintenance.

Hearing Conservation Program: Revised Interim Navy Medicine Hearing Conservation Program Guidance (April

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 this report. Ensure personnel are wearing double hearing protection for noise hazardous operations in excess of 96 decibels. Adequate supplies of hearing protection with differing styles were available for checkout.

Personal Protective Equipment (PPE): Personnel were observed wearing appropriate PPE during the walkthrough. Adequate supplies of hearing, hand and sight protection were available in the HAZMAT checkout rooms. Ensure personnel replace exhausted PPE as needed. Continue to ensure adequate supplies are maintained for employee issue.

Respiratory Protection Program: Respirators are worn by sheet metal personnel that conduct extensive sanding/grinding corrosion removal (approximately monthly). Personnel wear 3M half face, North full face and

Bullard supplied air hood respirators. Ensure personnel that utilize tight-fitting half or full face respirators are clean shaven to ensure a proper seal can be achieved between the face and respirator as mandated in 1910.134.

Continue to ensure that all personnel required to wear a respirator are fit tested and trained. Contact the RPPM at the FRCE Safety Office with any questions regarding the Respiratory Protection Program.

Thermal Stress: Personnel are subject to thermal stress during both flightline and hangar operations. Personnel can spend extended periods of time on the flightline for aircraft run-ups and troubleshooting evolutions. In addition, employees often perform work in interior aircraft and component spaces that are excessively warm, especially in protective coveralls. No thermal comfort issues were reported during the workspace walkthroughs. Ensure all personnel are trained in thermal stress recognition and prevention. Supervisory personnel should contact the FRCE

Safety Office if assistance is needed with thermal stress training.

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.

Changes in Workplace Processes: This report reflects conditions and operations in V-22 95101 and 95301 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 2016.

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.

EVALUATION SUMMARY

PERIODIC INDUSTRIAL HYGIENE SURVEY

V-22 IMP/MOD (95101 and 95301)

New or Significantly Modified Work Center Operations/Processes?

No significant changes in operations/processes were identified. *

The following changes were identified: The shop supervisor advised that larger scale corrosion removal operations are conducted approximately once a month. Based on Similar Exposure Group (SEG) monitoring data, exposures above the

Permissible Exposure Limit (PEL) are expected for chromium VI.

*For purposes of this survey, “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).

The previous survey assessed a combined shop (95101/95301). These shops have since divided and are assessed separately.
