Current Challenges in Sampling & Analysis: Rules, Strategies, and Devices 

The New Rule on Silica Demands More From Your Lab!

This study shows how an Industrial Hygiene Laboratory can meet the criteria of quantitation limits in Appendix A for the final rule on respirable crystalline silica. 

Dilemmas with Silica Sampling Strategies and Interpretation

Issues occur when quantifying exposures to crystalline silica for short-term work tasks due to sample duration, method analysis and sample collection limitations. Three case studies will be used as examples: (a) engraving with Tripoli, (b) food coloring process using cristobalite in mixture, and (c) drum filter mixture using 1.5% silica. The Ontario OEL's are used for provincial regulatory purposes and compared with the Canadian government use of the more stringent ACGIH TLVs. 

Direct Reading Plus Sample Collection in One Device

Bagging, pouring, firing, molding, abrasing are typical processes in many factories around the world. The presenter takes us through a case study from a factory that can now monitor, in real-time, a whole process over a full shift and pinpoint the danger areas to industrial workers so actions can be taken to minimize their exposure. Then the same dust sample is used to correlate with the standard method and analyze the results. 

A Review on Airborne Fungal Spore Sampling Devices 

Different fungal spore sampling devices: 1. common spore traps(e.g. Air-O-Cell and Allergenco-D), 2. filtration-type spore traps(e.g. Bir-Air), 3. filtration-type spore trap with a large MCE membrane filter, 4. others (Andersen impactor, impinger, button sampler) will be compared. Operating principles, % collection rate, fly-by & bounce-off, overloading, temperature influences, flow rates, and microscopy & culture analysis are among the sampling device parameters that will be discussed.

The Complexities of Soil Sampling for Asbestos and Other Mineral Fibers 

When trying to properly assess Asbestos and other mineral fibers, soil is a problem matrix. What is the sample to be collected? Where and how may samples do we collect? Shall we collect grab samples, incremental samples and/or composite? These approaches will be discussed along with their advantages and disadvantages. There are a multitude of analysis options including observation in the field, stereomicroscopy, PLM, SEM, TEM and XRD. Advantages and disadvantages of each will be discussed. For risk assessment, ABS (Activity Based Sampling) and the FBAS (Fluidized Bed Asbestos Segregator) will be discussed.

Challenges and Innovations in Sampling & Analysis Methodology 

The Difference Between NOA and ACM is More Than Just Two Letters

The conversations surrounding asbestos continue to evolve. In the early 1980's it started with bulk building material asbestos. A paradigm shift occurred when naturally occurring amphiboles (NOA) were found to have adverse health effects. We, as a lab, are asked to identify all elongate mineral particles (EMP), not just the six regulated-minerals. The driving force of this analysis has been to determine the impact fibers can have on human health. Currently, no published method exists for the identification of minerals outside the regulated 6, and each laboratory seems to have its own approach. The level of analytical effort a lab puts toward NOA analysis is vastly different to the effort put forth in ACM analysis. This case study will aid site investigators on what they should be aware of when asking for non-routine asbestos analysis to ensure the data they receive is repeatable, reliable and defensible. 

Production of Reference Materials for the Measurement of Metal Oxides

The scientific institutes of German Social Accident Insurance IFA, IPA and IGF have developed a new method to prepare 96 membrane filters evenly loaded with metal dust. The samples were succesfully used for IFA`s PT scheme and it is planned to improve the technique for the preparation of a reference material. 

A Comparison of Sampling & Testing Options for Fire Damage Investigations

This presentation provides a comparison of sampling methodologies and analytical techniques available for fire debris analysis. The capabilities and limitations of the sampling options typically used in the field are evaluated in parallel with discussion about the applicable analytical methods for characterization and quantification of the fire residue components. 

Sampling and Analysis of Air Contaminants 

Sampling and analysis of air contaminants in occupational environments is no easy task. This session will help attendees understand some of the principles of method performance evaluation for select analytes including diacetyl, formaldehyde, and other analytes like aromatics, ketones, and nitrous oxide. Topics will include: 1) canister sampling for diacetyl and other flavorings; 2) review of formaldehyde sampling and analytical methods; and 3) review of the principles, practices, and equipment for performance validation of personal monitoring badges. This session is sponsored by the Sampling and Laboratory Analysis committee.

Developments in Beryllium Regulation, Sampling and Laboratory Analysis 

Beryllium regulations worldwide have been in a state of flux with rulemaking proposals from OSHA, the Department of Energy, and the Working Party on Chemicals in the European Union. It is difficult to keep up with what is needed to stay compliant and more importantly, to properly protect workers. This session, offered by the Sampling and Laboratory Analysis Committee, provides an update on regulations and compliance deadlines. It also provides insights on best practices for sampling and laboratory analysis, based on the Practitioner's Guide to Beryllium Hazard Management prepared by the Beryllium Health and Safety Committee.

How to Conduct Sampling for Fire-Related Particulates and Odors 

Fire-related compounds are ubiquitous in indoor/outdoor environments and can adversely impact indoor/outdoor air quality. Fire compounds can cause a wide range of exposure concerns ranging from irritation to cancer. It is reasonable to ensure that fire-affected indoor and outdoor environments are properly remediated. This discussion will focus on indoor fire remediation. The Remediation Industry Association (RIA) has developed guidelines for fire remediation and sampling. Investigation of fire-affected properties requires knowledge of investigation methods, construction, remediation, and industrial hygiene concepts, and an understanding of applicable fire-related compound sampling methods and their limitations.​
