Safety Matters/Teen Workplace Safety Beta Group Task Force

Volunteer opportunity for AIHA members:
I am currently chairing the Safety Matters/Teen Workplace Safety AIHA Beta Group Task Force. We are just getting started and I am  accepting AIHA member volunteers to serve on this task force. Like any task force, this will require a few conference calls and several emails with a specific time limit. Please contact me if you are interested in serving in this capacity.

What is Safety Matters? This general awareness training program developed jointly by the National Institute of Occupational Heath and Safety (NIOSH) and the American Industrial Hygiene Association (AIHA) is designed to teach young workers how to identify workplace hazards and know their rights as workers.

Why is this important? Here are some statistics you may not know: 
  • "Approximately 1.6 million U.S. teens (aged 15–17) work.
  • Every nine minutes, a U.S. teen is injured on the job.
  • On average, each year:
Want to help bring Safety Matters to your community and teach young workers to expect a safe workplace? Then contact me to learn how you can mobilize this effort locally.

Low level measurements of benzene exposure in the workplace and at ppt levels at fencelines via gas chromatography/photoionization detection
Mini GC121
Benzene is a known carcinogen and long term exposure to this chemical may result in leukemia. The Occupational Safety and Health Adminstration (OSHA) permissible exposure limit (PEL) for benzene, established in the 1980’s, was 1 ppm. In the 1980’s, tetra ethyl lead, an octane booster, was removed from gasoline and replaced with these aromatic hydrocarbons: Benzene, Toluene, Ethylene and Xylene (BTEX). In 1990, benzene was one of 189 hazardous air pollutants (HAPS) identified by the Environmental Protection Agency (EPA) in the Clean Air Act of 1990. As a result, the quantity of benzene in gasoline was gradually reduced to limit the benzene emitted to the atmosphere. In 2015, EPA announced a plan to regulate benzene at 2.8 ppb at the fenceline of refineries and chemical plants since neighbors of these facilities could experience exposure to low levels of benzene in the ambient air for 24 hours per day.
The OSHA limits (PEL = 1.0 ppm) for the workplace (chemical plants, gas pipelines, shipyards etc.) can be measured at the 1 ppm level using a portable gas chromatograph configured with a photoionization detector (GC/PID). The EPA limit of 2.8 ppb at refinery
and chemical plants fence lines is near the detection limits for most GC/PID’s so a low power concentrator would be needed to measure sub ppb levels of benzene without interference from hexane or other alkanes present. A new mini hand-held GC based analyzer that will be able to measure benzene in the workplace at ppb levels and at ppt levels in refinery and chemical plant fencelines will be described.

Real-time detection of toxic arsine vapors in the workplace at low ppb levels

ABSTRACT SYMPOSIUM NAME: Advances in Separations

Abstract: Arsine (AsH3) is a flammable and toxic hydride gas that is used in the manufacture of semiconductors and organic arsenic compounds. The permissible exposure limit (PEL) for arsine (29 CFR 1910.1000 Z-1 Table) is 0.05 ppm, 0.2 mg/m3 time weighted average (TWA). Arsine has a low Immediately Dangerous To Life or Health Concentration (IDLH): value of 3 ppmIn the semiconductor doping operation the tanks have arsine at percent levels so even small leaks can cause serious problems.
The on-site method for AsH3 detection is a detector tube which (depending of the manufacturer) can have detection limits from 0.02- 5 ppm according to the Occupational Safety and Health Administration. Clearly, the latter tube is not of much use since the IDLH for AsH3 is 3 ppm. Several of the other detector tubes have detection limits that are just below the PEL and are not very accurate.

We have developed a new hand held gas chromatograph/photoionization detector (GC/PID) that has a detection limit of 5 ppb and an analysis time of less than 1 minute. This GC can be used for leak detection and determining the concentration of AsHin the workplace. It also provides a safer environment for the workers than the detector tubes.

Benzene is a known carcinogen and long term exposure to this chemical may result in leukemia. The OSHA permissible exposure limit (PEL) therefore is 1 ppm and the short term exposure limit (STEL) is 5 ppm. EPA has just announced (October 2016) a plan to regulate benzene, at 2.8 ppb, at the fenceline of refineries and chemical plants. It is clear that even low ppb levels of benzene are a health concern so that the measurement of benzene in the workplace at ppb levels should be a concern for industrial hygienists.
We have developed a five pound, compact GC/PID system that will utilize a special 10.0 eV/10.2eV lamp to improve the specificity for benzene. We have employed a capillary column to provide a fast, specific, and sensitive method for benzene. As a result, we can detect > 1 % of the PEL. The analysis time for benzene is 1 minute, so, five measurements can be used to determine the STEL. The reproducibility (CV) for benzene at 1 ppm is 1-2% and 4-5% at 1/10th of the PEL.
A concentrator has been developed that fits on the tip of probe of the analyzer. A valve is selected to determine whether the sample is directed to the GC or the concentrator. The volumetric flow is measured with a calibrated flow sensor in the analyzer and date, time and location are recorded. This adsorbent can returned to the lab for confirmatory analysis of benzene and any other components trapped on the adsorbent.
Having a simple, effective and accurate real-time method to meet monitoring needs of workers is critical to remain in compliance with the present or new OHSA standards for benzene. This system is designed for multiple users, features a color graphics screen with simple push button operation and remote data collection via Bluetooth.

How will this help advance the science of IH/OH?
Real-time detection systems help limit worker exposure to chemical hazards. This scientific presentation will discuss the specific hazards and share new tools that will improve the accuracy of detection (without the use of detector tubes) as well as allow operators to collect samples for lab verification while capturing the real-time field analysis data. This equipment is ruggedly designed for a multi-user environment with various levels of technical expertise.

Another  American Chemical Society National Meeting in the books! True to form, this meeting was incredibly busy and marked my first meeting in the Chair succession of the ACS Divisional Activities Committee subcommittee's Multidisciplinary Program Planning Group (MPPG) which is responsible for the thematic programming
 for ACS National Meetings. I organized the Advances in Analytical Separations Analytical Chemistry Division flagship program for the fifth consecutive ACS National Meeting in which I presented "Screening and on-site identification of accelerants for arson investigations". This talk focused on the protocol used by arson investigators  by utilizing a photoionization detector (PID) as a preliminary screening tool and then employing a hand-held mini gas chromatograph to identify the species used to start the fire. This presentation is available upon email request. 

Our own, Jack Driscoll, is the 2017 Edward J. Baier Technical Achievement Award Recipient presented by the American Industrial Hygiene Association!

"The Baier Award  is given to the individual or group of individuals, company, academic institution, organization, or association that has made the most significant contribution to industrial hygiene in recent years through technical expertise, innovations, or scientific advancements.
John N. Driscoll, PhD - Edward J. Baier Technical Achievement Award  
John (Jack) Driscoll is an innovator in the development of a photoionization detector (PID) for gas chromatography. Driscoll quickly recognized the potential for PID technology in a stand-alone detector in the 1970s. His innovations and farsighted development of PID technologies have led to a transformation in real-time detection tools used by the IH profession. He has also had a tremendous impact on a diverse range of other scientific disciplines".
