I. Executive Summary

At the request of the National Guard Bureau Region West Industrial Hygiene Office, field 

personnel representing the U.S. Public Health Service, Division of Federal Occupational Health 

(FOH) conducted an industrial hygiene survey at the Alaska Army National Guard, Kenai 

Armory, located in Kenai, Alaska. This survey was conducted as part of the Army National 

Guard occupational safety and health program to evaluate potential personnel exposure to 

contaminants generated during typical activities performed at this facility. 

The Kenai Armory was built in 1970. The armory was renovated and an addition was added in 

2009. The facility has about 14,000 square feet of floor space that encompasses a drill floor, 

supply room, offices, classroom, kitchen, library, shower room, mechanical room, latrine, 

exercise room, locker room, maintenance bay and arms room. The armory had a firing range in 

the rear of the building that was closed in 1987. Site personnel reported that a lead abatement 

project was performed in the former firing range area in 2005. The former firing range area has 

been converted to a maintenance bay. The Kenai Armory is the base of operations for Bravo 

Troop 1 – 297th Reconnaissance and Surveillance. Site personnel reported that no vehicle 

maintenance is performed in the armory. 

The industrial hygiene survey included a walkthrough of the facility and interviews with 

employees. The survey also included collecting surface wipe samples for heavy metal 

contamination and a lighting survey. 

A bulk paint chip sample was collected from peeling paint on the outside of an exit door. The 

sample was analyzed for lead. The results were below the limit of detection for lead (<0.005 % 

by weight). 

Five samples were collected on representative surfaces in the facility and analyzed for three 

heavy metals (lead, cadmium and chromium). At present, there are no regulated or recommended 

levels for surface levels of heavy metals in military facilities. There are no OSHA regulated 

levels for these heavy metals on surfaces. For purposes of this report, any level of any metal that 

exceeds 200 ug/ft2

 is considered significant. One of the surface wipe sample results exceeded the 

above criteria. Sample AKKEW14 which was collected on an overhead HVAC duct in the drill 

floor area had a lead concentration of 350 ug/ft2. The Kenai Armory should continue to prohibit 

the presence of food and drink in work areas, stress the importance of hand washing prior to the 

consumption of food items and continue to clean the horizontal surfaces in work and storage 

areas. When weapons are cleaned, special attention should be given to cleaning up the work area 

to prevent potential lead contamination from ammunition. 

A lighting survey was conducted in the offices and storage areas in the Kenai Armory. Most of 

the areas surveyed did not meet minimum illumination requirements. Illumination levels should 

be improved in some office and storage areas.

Methodology and Assessment Criteria

Methods used in this survey to collect surface wipe samples are listed below. The sampling 

strategy used in this survey was designed to characterize employee exposure to the various 

contaminants that could be generated from the various activities/tasks performed in the facility. 

It was based, in part, on information provided by site personnel. 

Surface sampling reported in this survey represents the work conditions existing at the time of 

the survey. Changes in work practices and/or processes may change employee exposure levels. 

Use of different materials may result in exposure to a different air contaminant. 

 

Surface Sampling – Heavy Metals 

Surface samples were collected from representative areas using Environmental Express GhostTM 

Wipes and templates that encompassed 100 centimeters squared (cm2

) of surface area. The 

entire area was wiped using an “S” configured motion, the GhostTM Wipe was then folded in half 

and the area was again wiped in a direction 900 to the first using an “S” motion. The wipe was 

folded again and the perimeter of the area was wiped. The wipe was then placed into a plastic 

cylinder, the cylinder was capped and sealed and the samples were sent to the FOH Laboratory 

in Chicago, Illinois, for analysis for multiple metals. The cadmium, chromium and lead samples 

were analyzed on a Perkin Elmer 200 flame atomic absorption spectrophotometer using the 

OSHA ID-121 method. At present there are no regulated or recommended levels for surface 

levels of heavy metals in military facilities. For purposes of this report, any level of any metal 

that exceeds 200 ug/ft2 is considered excessive (or significant). 

A bulk sample of peeling paint was collected and sent to the FOH Laboratory in Chicago, 

Illinois, for analysis for lead. This sample was analyzed on a Perkin Elmer 200 flame atomic 

absorption spectrophotometer using the OSHA ID-121 method. 

Lighting Levels 

Illumination levels were measured with a Sper Scientific 840022 Broad Range Lux/FC Meter 

that had been calibrated according to the manufacturer’s instructions. Illumination levels were 

recorded as foot candles.

l. Executive Summary 

At the request of the National Guard Bureau Region West Industrial Hygiene Office, 

field personnel representing the U.S. Public Health Service, Division of Federal 

Occupational Health (FOH) conducted an industrial hygiene survey at the Alaska Army 

National Guard Army, Armory located in Ketchikan, Alaska. This survey was conducted 

as part of the ARNG occupational safety and health program to evaluate potential 

exposure to lead on facility surfaces. Surface wipe samples were collected for lead 

dust. 

The NGB-ARS Memorandum for the Chiefs of Staff dated February 2, 2006 provides 

guidance for potential lead hazard exposure in Army National Guard child occupied 

facilities. The memorandum defines a child occupied facility as a building, or portion of 

a building, visited on a regular basis by the same child, six years of age or under. Child 

occupied facilities may include, but are not limited to, day-care centers, preschools, and 

kindergarten classrooms. The memorandum states that, “For all areas used/occupied 

on a regular basis by children ages six and under clean all floors accessible to said 

children to the EPA dust-lead standard of 40 ug/ft2. Clean all other surfaces in 

accordance with USACHPPM recommendations for lead in dust of 200 ug/ft2on 

frequent contact surfaces.”

For purposes of this report any surface lead level that exceeds 40 ug/ft2 in a child 

occupied area is considered significant. Any surface lead level that exceeds 200 ug/ft2

in any other area of the armory is considered significant. 

Six surface wipe samples were collected on representative surfaces throughout the 

facility and analyzed for lead. One sample from the top of a locker in the former firing 

range contained lead levels of 140 ug/ft2. This level is below the recommended surface 

lead level of 200 ug/ft2. A second sample collected on a metal support for a basketball 

hoop in the Drill room also had 140 ug/ft2 of lead. The concern with the lead levels on 

the basketball hoop and ceiling rafters in the Drill room is the potential for the lead 

containing dust to fall to the floor below if disturbed by wind or vibration. Unlike the 

former firing range, the assembly room is used by the public and Guard employees. It 

is recommended that the upper surfaces in the assembly room be cleaned of the leadcontaining dust. 

A bulk sample of material was collected from the floor in the mechanical room. The 

sample contained 5 to 10 percent chrysotile asbestos and 3 to 6 percent amosite 

asbestos. An asbestos building inspection should be conducted in the facility to identify 

all asbestos containing building materials and all friable asbestos material should be 

removed or encapsulated. 

A lighting survey was conducted in the shops and offices in the Armory. Most of the 

areas surveyed did not meet minimum illumination requirements.

II. Introduction 

An industrial hygiene survey was conducted by the U.S. Public Health Service (USPHS) 

Federal Occupational Health (FOH) at the Alaska Army National Guard Army, Ketchikan 

Armory located in Ketchikan, Alaska. This work was conducted under the Interagency 

Agreement between the USPHS, FOH and the West Region of the Army National 

Guard. This survey was conducted in order to identify lead levels on surfaces within the 

Armory. , Certified Industrial Hygienist (CIH); 

and , CIH conducted the survey on July 20, 2010. This report was 

prepared by . 

FOH conducted this survey in the interest of preventing employee illness and in meeting 

legal obligations where applicable. Based on information provided, every effort was 

made to conduct a comprehensive survey covering the parameters considered. Results 

and recommendations are based on information provided, field measurements, and 

conditions observed during the survey. 

III. Site Description 

The Ketchikan Armory was constructed in the late 1960s. A former firing range is 

located in the basement and now used as a locker room. The range has been cleaned 

of lead dust but may need additional cleaning. The building also includes; offices, 

classroom, vault, break room, workout room, supply room, storage rooms, mechanical 

room, and janitor closet. 

 

The Armory is staffed by one full-time employee and 15 part-time Guard employees. 

The Drill hall or assembly room is used by Guard employees and the public. 

Approximately 30 to 40 children ages 7 to 18 years old use the Drill room each week to 

play basketball.

IV. Scope of Work 

Lead dust from firing ranges and the cleaning of fire arms can contaminate surfaces 

within a building. Therefore, six surface wipe samples were collected and analyzed for 

the presence of lead. A surface area of either 16 or 144 square inches was wiped with 

a Ghost Wipe, place in a plastic coin tube and shipped to the FOH Analytical Laboratory 

in Chicago, Illinois. The samples were then analyzed by flame atomic absorption 

spectrophotometer (AA) according to OSHA Analytical Method ID-121. 

A bulk sample of material was collected from the floor of the mechanical room and 

tested for fiber content. 

V. Assessment Criteria, Findings, Discussion, and Recommendations

Assessment Criteria for Surface Lead 

The NGB-ARS Memorandum for the Chiefs of Staff dated February 2, 2006 provides 

guidance for potential lead hazard exposure in Army National Guard child occupied 

facilities. The memorandum defines a child occupied facility as a building, or portion of 

a building, visited on a regular basis by the same child, six years of age or under. Child 

occupied facilities may include, but are not limited to, day-care centers, preschools, and 

kindergarten classrooms. The memorandum states that, “For all areas used/occupied 

BEST AVAILABLE COPY BEST AVAILABLE COPY FOIA Requested Record #J-15-0085 (AK)

Page 27 of 61
on a regular basis by children ages six and under clean all floors accessible to said 

children to the EPA dust-lead standard of 40 ug/ft2. Clean all other surfaces in 

accordance with USACHPPM recommendations for lead in dust of 200 ug/ft2on 

frequent contact surfaces.”

For purposes of this report any surface lead level that exceeds 40 ug/ft2 in a child 

occupied area is considered significant. Any surface lead level that exceeds 200 ug/ft2

in any other area of the armory is considered significant. 

Surface Samples

Six surface wipe samples were collected on representative surfaces throughout the 

facility and analyzed for lead. One sample from the top of a locker in the former firing 

range contained lead levels of 140 ug/ft2. This level is below the recommended surface 

lead level of 200 ug/ft2. A second sample collected on a metal support for a basketball 

hoop in the Drill room also had 140 ug/ft2 of lead. The concern with the lead levels on 

the basketball hoop and ceiling rafters in the Drill room is the potential for the lead 

containing dust to fall to the floor below if disturbed by wind or vibration. Unlike the 

former firing range, the assembly room is used by the public and Guard employees. It 

is recommended that the upper surfaces in the assembly room be cleaned of the leadcontaining dust. The results are contained in Table 1.

I. Executive Summary

At the request of the National Guard Bureau Region West Industrial Hygiene Office, field 

personnel representing the U.S. Public Health Service, Division of Federal Occupational Health 

(FOH) conducted an industrial hygiene survey at the Alaska Army National Guard, Kenai 

Armory, located in Kenai, Alaska. This survey was conducted as part of the Army National 

Guard occupational safety and health program to evaluate potential personnel exposure to 

contaminants generated during typical activities performed at this facility. 

The Kenai Armory was built in 1970. The facility has 10,800 square feet of floor space that 

encompasses a drill floor, supply room, offices, classroom, kitchen, library, shower room, 

mechanical room, latrine, weight room, locker room, maintenance bay and arms room. The drill 

floor and maintenance bay areas have a concrete floor, concrete block walls that are 14 feet high, 

and steel beams supporting a sloped roof. The exterior of the building is masonry. On the day of 

the survey a 12.5 foot wide addition was being added to the front of the armory. The armory had 

a firing range in the rear of the building that was closed in 1987. Site personnel reported that a 

lead abatement project was performed in the former firing range area in 2005. The former firing 

range area has been converted to a maintenance bay. The Kenai Armory is the base of operations 

for Headquarters Company B 3rd Battalion Scout 297th Infantry and Bravo Troop 1 – 297th

Reconnaissance and Surveillance. Site personnel reported that light vehicle maintenance may be 

performed in the armory. 

The industrial hygiene survey included a walkthrough of the facility and interviews with 

employees. The survey also included: collecting surface wipe samples for heavy metal 

contamination and a lighting survey. 

Five samples were collected on representative surfaces in the facility and analyzed for three 

heavy metals (lead, cadmium and chromium). Some of the sample results were below the limit of 

detection for the metals and other results indicated that metals were detected, mostly at lower 

levels. At present, there are no regulated or recommended levels for surface levels of heavy 

metals in military facilities. There are no OSHA regulated levels for these heavy metals on 

surfaces. For purposes of this report, any level of any metal that exceeds 200 ug/ft2

 is considered 

significant. One of the surface wipe sample results exceeded the above criteria. Sample AKEW5 

which was collected on a gun rack in the vault had a lead concentration of 314 ug/ft2. The Kenai 

Armory should continue to prohibit the presence of food and drink in work areas, stress the 

importance of hand washing prior to the consumption of food items and continue to clean the 

horizontal surfaces in work and storage areas. When weapons are cleaned, special attention 

should be given to cleaning up the work area to prevent potential lead contamination from 

ammunition. 

A lighting survey was conducted in the offices and storage areas in the Kenai Armory. Most of 

the areas surveyed did not meet minimum illumination requirements. Illumination levels should 

be improved in some office and storage areas.

Methodology and Assessment Criteria

Methods used in this survey to collect surface wipe samples are listed below. The sampling 

strategy used in this survey was designed to characterize employee exposure to the various 

contaminants that could be generated from the various activities/tasks performed in the facility. 

It was based, in part, on information provided by site personnel. 

Surface sampling reported in this survey represents the work conditions existing at the time of 

the survey. Changes in work practices and/or processes may change employee exposure levels. 

Use of different materials may result in exposure to a different air contaminant. 

 

Surface Sampling – Heavy Metals 

Surface samples were collected from representative areas using Environmental Express GhostTM 

Wipes and templates that encompassed 100 centimeters squared (cm2

) of surface area. The 

entire area was wiped using an “S” configured motion, the GhostTM Wipe was then folded in half 

and the area was again wiped in a direction 900 to the first using an “S” motion. The wipe was 

folded again and the perimeter of the area was wiped. The wipe was then placed into a plastic 

cylinder, the cylinder was capped and sealed and the samples were sent to the FOH Laboratory 

in Chicago, Illinois, for analysis for multiple metals. The cadmium, chromium and lead samples 

were analyzed on a Perkin Elmer 200 flame atomic absorption spectrophotometer using the 

OSHA ID-121 method. At present there are no regulated or recommended levels for surface 

levels of heavy metals in military facilities. For purposes of this report, any level of any metal 

that exceeds 200 ug/ft2 is considered excessive (or significant). 

Lighting Levels 

Illumination levels were measured with a Sper Scientific 840022 Broad Range Lux/FC Meter 

that had been calibrated by the manufacturer. Illumination levels were recorded as foot candles.

Occupational Health Risk Assessment Codes 

(Reference: DOD Letter of Instructions 6055 1) 

Occupational health risk assessment codes (RACs) are included in this report to quantify health risks to personnel risk assessment is an expression of health hazard 

severity and mishap probability, described in terms of route of exposure, actual exposure, exposure limit standards, potential health effects, duration of exposure, and 

number of exposed personnel The following procedure is used to determine the RACs: 

STEP 1: This step assesses points to determine the health hazard severity category (HHSC) The HHSC reflects the magnitude of exposure to a physical, chemical, or 

biological agent and the medical effects of exposure 

A Exposure Points Assessed 

Alternate Route

Exposure Conditions 

<CT Occasionally >CT >CT >STD 

AER 

Possible 

NO 0 3 5 7 

YES 1-2 4 6 8 

Notes: 1) AER = Alternate exposure route, such as skin absorption or ingestion 2) CT = DoD component threshold that triggers surveillance actions, such as action 

level 3) STD = DoD exposure limit, such as TLV or PEL 4) > = Greater than 5) < = Less than 6) < = Less than or equal to 

B Medical Effects Points Assessed 

Condition Points 

No medical effects, such as nuisance noise and nuisance odor 0 

Temporary reversible illness requiring supportive treatment, such as eye irritation and sore throat 1-2 

Temporary reversible illness with a variable but limited period of disability, such as metal fume fever 3-4 

Permanent, nonsevere illness or loss of capacity, such as permanent hearing loss 5-6 

Permanent, severe, disabling, irreversible illness or death, such as asbestosis or lung cancer 7-8 

C The HHSC is determined by totaling the points assessed and using the following guide
