MEMORANDUM FOR: The Adjutant General for Indiana 

SUBJECT: Industrial Hygiene Survey at Brazil Armory, Brazil, Indiana 

National Guard Bureau (NGB) Mid-West Regional Industrial Hygiene (IH) Office field personnel 

conducted a survey on July 18, 2014 at the Indiana Army National Guard Brazil Armory, located 

at 970 West Craig Avenue, Brazil, Indiana. The site point of contact was . This IH

survey included a walkthrough of the facility and surface wipe sampling for lead. In addition, the 

ventilation system in the kitchen was evaluated. 

Occupational health risk assessment codes (RACs) are assigned to quantify health risks to 

personnel IAW DOD Letter of Instruction 6055.1, DOD Safety and Occupational Health 

Program. 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. Guidance for RAC 

determination is attached to this memorandum. 

Surface Wipe Sampling: Wipe samples were collected on representative surfaces in the 

facility and analyzed for lead. For purposes of this report, any results that exceed the guidelines 

adopted by the NGB Mid-West Regional IH Office are considered significant. None of the 

surface wipe sample results exceeded guidelines for lead. The following actions are required:

 Continue to clean the horizontal surfaces of the facility using high-efficiency particulate air 

(HEPA) filter vacuum and/or wet methods. (RAC 3) 

 Continue to prohibit the presence of food and drink in work areas and stress the importance 

of hand washing prior to the consumption of food items. (RAC 3) 

Ventilation: The ventilation system in the kitchen was evaluated and was not adequate for the 

tasks performed. There is no exhaust hood in the kitchen to capture smoke, grease-laden 

vapors, odors and excessive heat produced by the range/oven IAW criteria established by the 

American Conference of Governmental Industrial Hygienists (ACGIH) Industrial Ventilation, A 

Manual of Recommended Practice for Design, NGB Design Guide 415-1, Readiness Centers 

Design Guide, and TB MED 530, Tri-Service Food Code. The following actions are required:

 Install a Type I medium duty kitchen hood over the range/oven that provides a minimum 

exhaust flow rate of 300 cubic feet per minute per linear foot of hood length and a capture 

velocity at the cooking surface of 75 feet per minute. Follow the design criteria published in

Metals 

Surface Wipe Sampling 

There is no active or renovated firing range in the facility (Figure A-1) and weapons are cleaned 

on the drill floor. Children use this facility on a regular basis and the drill floor is available for 

public use by community groups. The facility was constructed in the 1950s. 

Wipe samples were collected from representative areas of the facility using Environmental 

Express GhostTM Wipes and templates IAW the Occupational Safety and Health Administration 

(OSHA) wipe sampling method (OSHA Technical Manual, Appendix II, 2-1). The samples were 

analyzed for lead by OSHA Method ID-121. The results and photos are contained in Table A-1. 

Although OSHA does not have published exposure standards for lead surface contamination, 

the 29 CFR 1910.1025(h)(1) requires that all surfaces must be kept as free as practicable of 

accumulations of lead dust. The NGB Mid-West Regional IH Office has adopted the guidelines 

for lead dust published in NG PAM 420-15, Guidelines and Procedures for Rehabilitation and 

Conversion of Indoor Firing Ranges. For purposes of this report, any surface lead level that 

exceeds 40 micrograms per square foot (μg/ft2) in a potentially child occupied area is 

considered significant. NGB IH considers facilities with routine public access to be potentially 

child occupied facilities. Any surface lead level that exceeds 200 μg/ft2 in any other work area 

of the facility is considered significant. None of the surface wipe sample results exceeded 

applicable guidelines for lead. There was some detectable lead measured in the drill floor area.

Figure A-1. Facility Photo.

Recommendations:

Continue to clean the horizontal surfaces in the facility to prevent the accumulation of lead dust 

from weapon cleaning using high-efficiency particulate air (HEPA) filter vacuums or wet 

methods. (RAC 3) 

Continue to prohibit the presence of food and drink in work areas and stress the importance of 

hand washing prior to the consumption of food items. (RAC 3)

Appendix D 

Ventilation 

The kitchen ventilation was evaluated for this facility in response to a request from the INARNG 

Occupational Health Nurse who observed smoke on the drill floor during a previous visit. The 

drill floor is adjacent to the kitchen. The kitchen staff was interviewed and provided the following 

information: 

 Visible emissions from the kitchen have escaped onto the drill floor area and caused 

disruptions in activities. Smoke also “pours” out the back door limiting visibility in the kitchen 

due to all the smoke in this space. 

 The ceiling exhaust grille is not adequate to collect emissions from the range/oven, 

especially when using the griddle. There is no wall switch for manual operation of the roof 

exhaust fan. 

 Smoke from the kitchen sometimes enters the adjacent maintenance area through the 

ceiling grille in the maintenance area. 

 Workers routinely open the door from the drill floor and the back door to assist in cross 

ventilating the space. They position portable floor fans at the drill floor door and at the 

outside door to assist with clearing the room of smoke and to provide cooling. 

 The kitchen does not have central mechanical cooling and there is no window air 

conditioning unit. 

 The kitchen is used up to three weeks per month during annual training. 

A TSI Alnor Model AVM430A thermal anemometer calibrated according to the manufacturer’s 

specifications was used to evaluate the kitchen exhaust ventilation system at this facility. 

Ventilation rates were compared to criteria established by the ACGIH Industrial Ventilation, A 

Manual of Recommended Practice for Design, NGB Design Guide 415-1, Readiness Centers 

Design Guide, and TB MED 530, Tri-Service Food Code. In addition, smoke tubes were used 

to evaluate the kitchen exhaust fan function. 

The kitchen general room ventilation exhausts 6.3 cubic feet per minute (cfm) per square foot of 

room space which meets the NGB DG 415-1 room exhaust rate of 1 cfm per square foot; 

however, ACGIH, DG 415-1, and TB MED 530 also specify the use of an exhaust hood for 

cooking appliances such as kettles, ranges, griddles, and fryers. There is no hood system in 

the kitchen to capture smoke, grease-laden vapors, odors and excessive heat produced by the 

range/oven IAW ACGIH, DG 415-1, and TB MED 530 requirements.

Recommendations:

1. Install a Type I medium duty kitchen hood over the range/oven that provides a minimum 

exhaust flow rate of 300 cubic feet per minute per linear foot of hood length and a capture 

velocity at the cooking surface of 75 feet per minute. Follow the design criteria published in 

the ACGIH manual and TB MED 530. Determine if the existing roof exhaust fan may be 

used or if a new fan is required to support these ventilation rates. (RAC 2) 

2. Coordinate with the safety office to ensure the kitchen ventilation system meets the fire 

protection provisions specified in National Fire Protection Association (NFPA) Standard 96, 

Ventilation Control and Fire Protection of Commercial Cooking Operations, and/or 

applicable local fire protection codes. (RAC 2) 

3. Provide mechanical cooling to the kitchen to minimize potential heat stress concerns. (RAC 

3)

4. Configure the exhaust fan and the passive air intake for the adjacent maintenance area so 

that kitchen smoke and grease-laden vapors are not back-drafted into the maintenance 

area. (RAC 3)

Lighting 

Illumination levels were measured with an Extech Instruments Model 407026 light meter 

calibrated according to the manufacturer’s specifications. The results were compared with the 

recommendations in the National Guard Bureau Facility Design Guides and the American 

National Standards Institute/Illuminating Engineering Society of North America RP-1 (Offices) 

and RP-7 (Industrial Facilities) guidelines. The results and the lighting criteria are contained in 

Table E-1. Illumination levels were only partially met in the maintenance bays and production 

control area. 

Recommendations:

1. Increase the illumination levels in the maintenance bays and production control area or 

provide supplemental lighting. (RAC 4)

Facility:

Tyndal Armory

Address:

711 N. Pennsylvania, Indianapolis, IN46204

Date: Feb 24, 2015 CIH: POCs:

Facility Description: Built in 1926, the armory is a four-story structure with a drill hall, kitchen, weapons vault, classroom, offices,

Family Assistance office, latrines, and supply storage. The former indoor firing range in the basement was converted to offices, storage 

room, cage storage, and training room (Governors Hall). The basement had also been used as a vehicle garage. It was also reported

that the Drill Room was used at times for target practice. The public does have access to the Drill Room, Kitchen, and Family 

Assistance office.

Community 

Use/Children

Y Description: The facility is used for public events that include children.

Weapons 

Cleaning

Y Locations: Drill room floor.

Summary: The focus of this sampling effort was to conduct a baseline lead dust survey of the armory. Table 1 contains the sampling 

results for 30 samples and the sampling locations.

The surface wipe sample result for the window sill in Jim Mahern’s office was 295 μg/ft2. This level was above the NG Pam 420-15 

guideline for lead of 200 μg/ft2. A sample collected on a window sill in an adjacent office, room 200A was 544 μg/ft2. The lead 

containing dust on the sills may be caused by chipping paint from the leaden windows. Seven samples were collected in the Drill room. 

Three samples had elevated levels of lead. In the basement two samples collected on the floor on the north end of the basement 

contained 11,500 and 12,500 μg/ft2. All other sample results were below the analytical laboratory reporting limit.

Recommendations:

 Increase housekeeping in the offices especially on the window sills and all surfaces in the drill room. Use a high efficiency 

particulate air (HEPA) filter vacuum or wet methods to clean these surfaces. (RAC 2)

 The rooms in the basement with high levels of surface containing lead should be closed to unauthorized personnel and signs 

posted of potential lead exposure hazard. (RAC 2)

 Areas of the basement with high surface lead levels should be decontaminated by individuals trained in lead abatement in 

accordance with the Guidelines and Procedures for Rehabilitation and Conversion of Indoor Firing Ranges NG PAM 420-15.

(RAC 2)

 The armory housekeeping staff should also be trained in the hazards of lead exposure and also follow the guidelines in NG PAM

420-15. (RAC 2)

 Weapons cleaning should be performed in an area not open to the public. (RAC 2)

 A follow-up survey should be conducted after a complete cleaning of surfaces in the occupied rooms to test for the presence of 

lead on surfaces. (RAC 3)
