Introducing AIHce EXP REPLAY, a virtual way to take part in conference sessions you missed, featuring the hottest topics presented at AIHce EXP, including full video, audio, and slides.

But this isn't a typical rebroadcast – the presenters will be available to chat with attendees and answer your questions – in real time! Best of all, you can earn educational credit.

REPL​AY sessions are carefully selected based on attendee feedback. There are four amazing sessions available in October. You can purchase one session, or all four with our B​undle Option​!


Real-Time Sensor Technology: Applications by IH Students
Tuesday, October 16, 2018 at 1:00 pm ET

 

Presenters: Leslie Allsopp, Brandon Jensen, Justin Cathey

 

Real-time direct reading technology is advancing rapidly, becoming affordable, and being adopted for exposure measurement, control applications and research. This technology allows IHs to get continuous and immediate measurements from multiple sensors, can be worn by workers, and can be linked to workplace environmental controls. Presenters will discuss the use of sensor selection, performance and integration into various building control system configurations, use of real time sensors to validate the well mixed room exposure model, and an evaluation of the precision and accuracy of off-the-shelf, affordable air quality sensors.

What attendees said about this presentation:

“Great group of presenters, excellent content, and good questions from the audience.”

“Great to see upcoming IH's pursuing very interesting research. Great to see them focusing on making IH more accessible and practical.”

“IH Students did an excellent job. I believe more questions were asked these students than in the other sessions I viewed. Great session.”​


Studies in Real-Time Detection Systems: Measuring Exposures
Thursday, October 18 at 1:00 PM ET

 

Presenters: Dr. Emanuele Cauda, NIOSH Pittsburgh, PA; Philip Smith, PhD, CIH, U.S. Department of Labor - OSHA Sandy, UT; Michael Berg Ph.D., EMLab P&K South San Francisco, CA  

 

Side by Side Evaluation of Real-time Personal Monitors for Respirable Dust 

The use of real-time monitors for respirable dust has become common among IHs. The sensing technology is an optical measurement which can be affected by dust properties and environmental conditions. This study will present the side by side comparison of four real-time dust monitors tested under different conditions in a calm air chamber. There are three main outcomes: 1) the inter-unit variability for each monitor was found to be relatively low; 2) the performance of the calibrated monitors when challenged with a standard material is not consistent; and 3) dust properties and relative humidity can greatly affect the monitors' performance. 

 
Intra-Sampling Period Variability: Strengths and Weaknesses of Real-Time Detection 

Air contaminant exposures often fluctuate during the sampling period. Laboratory analysis of time-weighted average (TWA) results provide no information about intra-sampling period concentration variation. A non-dispersive infrared sensor was used to track carbon dioxide concentrations in real time to examine the potential to exceed the Immediately Dangerous to Life or Health (IDLH) concentration. Exposures in excess of the IDLH value were measured with high certainty, where the TWA sample results did not indicate a problem. Strengths and weaknesses of real-time detection for truly comprehensive exposure assessment that considers intra-sampling period variability will be discussed. 

 
Rapid Systems for the Detection of Legionella Bacteria 

Monitoring of Legionella bacteria has received attention due to publicized outbreaks and new guidelines and regulations. Time consuming culture methods are considered the gold standard for the detection of Legionella bacteria. Other alternative methods with short turnaround time such as antibody and DNA based methods are available and may be helpful for fast detection in outbreak situations. We discuss our experience with a qPCR system (iQ-Check – RioRad) and an antibody-based detection system (Legipid – Primelab) for the rapid detection of Legionella bacteria in water samples.

What attendees said about this presentation:

"Another great session packed with technical content. Speakers/presentations were well chosen to meet the needs of practicing hygienists. Presentations were concise yet provided key technical details. Thanks to all 3”

“Enjoyed all three presentations, especially Dr. Berg's explanation of the detection principle for PCR.”

"All 3 speakers were very good and could have supported an entire session…”​


Should You Be Worried? EHS Professionals in Jail
Tuesday, October 23 at 1:00 PM ET

 

Presenter: Neil Feldscher

 

In the last decade, we have seen an increasing trend towards government criminal prosecution of what historically has been a regulatory violation and/or civil matter. While this was primarily with environmental matters, the frequency of this criminal prosecution in regard to health and safety matters has increased to a noticeable extent. In this talk we will focus on: 1. Some of the cases and examples of recent prosecutions of EHS personnel; 2. The elements of a criminal prosecution; 3. Recognition of criminal exposure; and 4. Criminal risk management.

What attendees said about this presentation:

"Great presentation! The presenter’s enthusiasm and competency made the session very interesting.”

" Excellent examples and definitely a conversation that needs to be held with EHS professionals as they enter the workplace."

"This speaker was phenomenal. I knew of most of the examples he gave; but his view point and the way he presented was like you were having a one on one conversation with him. Very good. Have him again.”​


Current Topics in Laboratory Health and Safety: Chemical Exposures & Ventilation
Thursday, October 25 at 1:00 PM ET

 

Presenters: Mr. Michael Menz, CIH, CHMM, EMSL Analytical Cinnaminson, NJ; Kenneth Brown PhD, NIOSH Cincinnati, OH; Alyssa Brand, Lawrence Berkeley National Laboratory Berkeley, CA

 

A Comprehensive Policy for the Management of Time Sensitive Chemicals

Old and forgotten chemical containers can pose significant hazards in the laboratory environment. Time-sensitive chemicals can become more hazardous upon prolonged storage. These containers must be actively managed to prevent serious incidents in the laboratory. This presentation focuses on the practical application of industry best practices to manage time-sensitive chemicals. The development process, including references and guidance used, will be discussed and the final policy, incorporating management practices for five categories of time-sensitive chemicals, will be shared.

 

Direct Reading Methods for Assessing VOC Exposures

Half a million US employees work in laboratories with volatile organic compounds (VOCs) which pose both toxicological and physical hazards. Traditionally, VOCs have been monitored using air pump and adsorbent tube techniques that are expensive, time consuming, and impractical. The advent of DRMs (direct reading methods) now make it possible to monitor VOCs in real time with significant accuracy and precision. Research was conducted to develop monitoring strategies using wireless PID sensors to effectively monitor VOC exposure and risk.

 

Laboratory Ventilation: Impact on the Building Environment

Chemical safety practices and laboratory engineering controls are taught to students and professional researchers. If random but recurring lapses in proper procedures occur, what would be the consequences, the effect on the indoor environmental quality, the effect on building systems? This case study summarizes the investigation initiated by concerns regarding poor air quality during an un-announced safety inspection and the findings on the effects on laboratory workers and building system components.

What attendees said about this presentation:

“I appreciated hearing about the approach taken by Berkeley National Lab for time sensitive chemicals and I thought the EMSL Lab case study was interesting.”

“Very technical presentation and very well done.”

“Great session, practical applications of IH issues and problem solving”​
