# PURPOSE: On July 20 and August 11, 2015, at your request, I visited the Amerex production facility located in Trussville, Alabama to conduct a limited industrial hygiene assessment. The purpose of the assessment was to evaluate the indoor air environment around the HalotronTM I hand portable extinguisher filling area to identify potential personnel exposures.
OVERVIEW OF ASSESSMENT RESULTS: The following pages of the assessment report discuss the collected exposure data and a discussion of their significance. Exposure concentrations are presented in parts per million (ppm) in air by location. 

# Background and Sampling Methods: Amerex manufactures a full line of hand portable and wheeled fire extinguishers. In Department 4, Amerex manufactures clean agent portable fire extinguishers and clean agent fire suppression systems. Amerex utilizes industry recognized HalotronTM I, DuPontTM FM-200®, 3MTM NovecTM 1230 Fire Protection Fluid, and recycled Halon 1211 to produce these clean agent fire extinguishers and systems. The focus of the industrial hygiene assessment was to characterize the potential personnel exposure in the HalotronTM I hand portable extinguisher filling area, but the other clean agents must be considered due to the cross sensitivity of the sampling equipment used. A Thermo ScientificTM MIRAN SapphiRe 205BXL Portable Ambient Analyzer, which is an industry standard instrument for this kind of work, was utilized to accurately measure the concentrations in air of constituents that include the Halotron TM 

# I agent. Halotron TM 

# I is a chemical blend based on the raw material dichlorotrifluoroethane (R-123) which is an included gas in the MIRAN SapphiRe XL 's factory calibrated 120 gas standard library. The MIRAN SapphiRe is a portable ambient air analyzer containing a single-beam infrared spectrophotometer. A microcontroller automatically controls the analysis, processes the measurement signal, and calculates the absorbance values. For R-123, analysis results were displayed in parts per million (ppm). The continuous sample logging mode was utilized to monitor various locations for various time periods. Reference, temperature, and humidity compensations were enabled during the continuous sampling mode. During the continuous logging mode, data was logged after every second. The analyzer measures data at a rate of two points per second, therefore for a log interval of one second there will be two data points to choose from. During the continuous logging, the analyzer stored the maximum, minimum, and average data result for the one second log interval. Various scenarios and locations were sampled in the Amerex facility on two separate dates.

# Sampling Results: On July 20, 2015, the primary purpose of the sampling event was to characterize the potential operator exposure in the Halotron TM 

# I filling area and to assess the effective capture of the Halotron TM I inside the extinguisher filling box by the local exhaust ventilation. On the date of the

# POTENTIAL FUTURE WORK: 

# Due to the cross-sensitivity issues encountered, accurate background levels for the HalotronTM I agent could be determined using a Tedlar® gas bag or other whole air grab sampling. IR monitors such as the MIRAN SapphiRe will respond to other gases which absorb at similar wavelengths, but a whole air grab sample could potentially help to understand the interference caused by the other chemical agents in the HalotronTM I filling area. The MIRAN SapphiRe portable ambient air analyzer accuracy must also be considered when discussing the sampling results. The factory calibrated tolerance for dichlorotrifluorethane (R123-H) is plus or minus 15% of the reading.
