EXECUTIVE SUMMARY

A periodic industrial hygiene survey was completed by Mr. John Williams, Industrial Hygienist. 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. Previous annual surveys contain information that may or may not be relevant to current working conditions, please keep the previous surveys for reference.

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 Safety Office compiles the registry and works with departmental secretaries to schedule required medical surveillance physicals with the Naval Health Clinic Occupational Medicine Department (OMD).

The OMD appointment scheduler may be contacted by fax number 466-6903 or emailing occ-appt@med.navy.mil.

Hazard Communication/Materials Program: All hazardous materials are drawn from storage and distribution areas throughout the FRC East. The Hazardous Material Distribution Support Center

(HDSC) maintains Authorized Use Lists (AUL) for hazardous materials used by the shops. Employees may obtain a Safety Data Sheet (SDS) from the HDSC when they check out the material or from their supervisor. In an emergency, if the computer system is down, employees may obtain the hard copy SDS from the Security Guard in Building 137. Managers/First line Supervisors shall ensure that personnel receive hazard specific training about the chemicals to which they are exposed prior to initial use. New employees are provided training on SDS accessibility at the new employee safety orientation. Additional training should be provided whenever there is a process change, employee transfers, new hazards, etc.

occur. Recent changes to the OSHA Hazard Communication Standard have prompted a requirement for training on the new SDS format. The new SDS format aligns with the Globally Harmonized System

(GHS). Please contact your hazardous communication program manager to determine when this training will be completed.

Hearing Conservation Program: Changes to the Navy hearing Conservation Program were announced through BUMED Note 6260, dtd 13 Dec 2012. Changes include the new Navy Occupational Exposure

Limit for Noise, set at 85 dB(A) with a 3 dB exchange rate, and the hearing protection device requirements have changed.

The Hearing Conservation Program was evaluated. The majority of all tools and equipment that produce sound pressure levels (SPL) of 85 dB(A) or greater are labeled. Hearing protective devices

(HPD) are required to be worn by all personnel whenever they work inside and/or enter designated noise hazardous areas. Employees are required to wear single HPD while operating or are near tools and/or equipment, regardless of duration, that produce SPL between 85 and 96 dB(A). Double hearing protection is required when noise levels, regardless of duration, are between 96 and 100 dB(A). For sound pressure levels greater than 100 dB(A), double hearing protection is required with administrative controls to bring the effective exposure to less than an 8-Hr TWA of 85 dB(A). The majority of personnel were observed wearing appropriate hearing protection during the survey. Continue to ensure that employees wear double hearing protection while they use compressed air to dry component parts.

Training on the Hearing Conservation program for ALL personnel is required per reference (a).

mailto:occ-appt@med.navy.mil mailto:occ-appt@med.navy.mil

Reference (a) is specific on the use of radios and/or head sets in noise hazardous areas. “The use of portable musical devices such as radio headphones, CD players, Walkman cassette/CD players, etc. is prohibited in industrial areas and in work areas where high noise hazards have been identified.”

Annual audiograms are required for employees who work in areas where the 8-hour time weighted average for noise is above the 85 dB(A) NOEL.

Respiratory Protection Program: The following items are noted:

SHOP 93202: Due to the potential for inhalation exposures to several carcinogenic and toxic metals, respiratory protection consisting of a half-faced air-purifying respirator with N-95 cartridges is highly recommended for metal spray operators during entry into the metal spray booths. Respirators should not be stored in the metal spray booths. Additional exposure monitoring data will be collected to determine inhalation exposures to the toxic metals used in the plasma and flame spray process.

SHOP 93201: Respiratory protection is worn voluntarily in the glove box blast room. Even though respirator use is for humanitarian reasons, employees need to follow the FRC East respiratory protection program requirements. Spot checks of the respirator program indicated personnel are current on training and medical surveillance. Please ensure employees store the respirators correctly.

Personal Protective Equipment (PPE): PPE is readily available for all personnel. PPE was observed to be in a clean, usable condition and properly stored.

Emergency Eyewash/Shower Stations: Pressurized plumbed eyewash stations are provided in all areas where required. These eyewash stations are clearly identified by highly visible signs. Continue to ensure that plumbed eyewash stations are activated weekly to verify proper operation and to flush the line of rust and other contaminants. Performance of weekly eyewash flushing/inspection is being documented.

Local Exhaust Ventilation (LEV): The LEV systems found are presented in tabular form preceding each worksite assessment. Each work process in this survey is referenced according to its corresponding

LEV system. Please review the comments regarding each LEV system for specific information pertaining to its operation. All LEV systems that do not meet the minimum recommended capture velocity are highlighted in bold print for quick and easy reference. These defective LEV systems should be evaluated further by FRC East maintenance and/or engineering personnel in order to correct these deficiencies.

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 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 personnel health so review of documentation and evaluation may be conducted.

Repeat Technical Findings:

Shop 93202: Booth #2 and Booth#3 in the Metal Spray work area are still underperforming and allowing metal spray powder to build up on surfaces within the booth.

Shop 93212: The paint booth, mixing room and blast booth are not meeting recommended ventilation rates.

Customer Satisfaction/Complaint Form: A customer satisfaction/complaint form is found in Appendix

D of this report. Please complete this form as deemed necessary and return to the Naval Health Clinic

Industrial Hygiene Department Head via the FRC East Safety Office.

This report reflects conditions and operations within FRC East Industrial Bulk Processes Branch 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 for this shop). 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 FRC East Safety

Office when significant changes occur.
