Industrial hygiene exposure monitoring

Threshold Limit Value Ceiling (TLV-C) The concentration that RDA should not be e, cceded during any part of the working e. posure. If conventional industrial hygiene instantaneous monitoring is not feasible, then the TLV-C can be assessed by sampling over a 15-minute period except for those substances that may cause immediate irritation when exposures arc short. 

Chapter 6, Radiation Safety, again teams up co-authors David Baldwin and Michael Williams. In this chapter, we are offered a comprehensive review of the various classifications and associated hazards of radiation as well as potential sources and specific radiation exposures in a cleanroom environment. Included in this chapter are industrial hygiene identification, monitoring and control practices specific to semiconductor processes and equipment.

A medical surveillance program is designed to protect the workers health. Given the limitations of industrial hygiene monitoring data and the many hazards involved in hazardous waste activities, medical surveillance data may provide the only indication that worker exposure to toxic substances has occurred.

Employee Exposure Monitoring. Industrial hygiene assessment of surface concentrations associated with a potent compound handled solely in liquid form within a chemical laboratory hood was conducted to assess the potential for downstream contamination potential. Handling operations assessed included dilutions of sample solutions and HPLC analysis. Wipe samples were collected from the following surfaces within and outside of the laboratory ... 

One of the most important objectives of any industrial hygiene monitoring program is to accurately interpret air sampling results. The use of statistics in this assessment process is necessary because all measurements of physical properties contain some unavoidable random measurement error. The variation of occupational exposure measurements is an argument for statistical information not against it. (10)(15)...
