¶ … benefit analysis that typically goes into decisions about sampling in industrial hygiene. The authors describe that there are two different main types of sampling -- active and passive. These come with different advantages and disadvantages, one of which is cost. Some others are the amount of time and effort required, and the accuracy of the sampling technique. The authors focus on the cost. Often, the sampling cost is viewed as an up-front cost, but of course this is not the entire picture -- in many cases discovering and addressing a problem early saves a lot of money. So the full cost-benefit picture needs to be taken into consideration when determining the optimal sampling technique.
The authors compared five passive monitors and one active monitor under a number of different scenarios. They found that overall the passive monitors had a better cost-benefit. They were in particular cheaper than the active monitor. The study, however, has an issue in its methodology in that there was only one active monitor type chosen. This means that when the results of the study are viewed honestly, the passive monitors only outperformed one type of active monitor, not the entire class of active monitors, as most types were not tested...
The most cost-effective passive monitor was one that used replaceable capsules, and this was particularly cost-effective when taking large numbers of samples. Intuitively, this makes sense. Active sampling of large numbers is inherently going to be expensive, maybe even cost prohibitive. The article does not spend much time talking about the other variables that might come into play, such as what type of contaminant is being tested for.
This article relates well to the module's lessons about sampling. Sampling is an important part of the industrial hygienist's job, and there is value in understanding the types of sampling, how accurate they are, and what they cost. In the real world, cost matters to employers, and industrial hygienists will have budgets, and they will need to justify those budgets. Thus, it is important that people practicing industrial hygiene have a sense of what the best sampling method is for a given situation. There will always be different constraints, so understanding how to work within these different constraints is a valuable practical skill. This journal in general has a…

911 Recovery Health and Safety Plan for 911 Recovery Operations: Lessons Learned Recommendations on Industrial Hygiene According to the Office of Occupational Health and Safety Administration (OSHA), industrial hygiene (IH) is of utmost importance to any work site. By definition, IH encompasses the science and art "devoted to the anticipation, recognition, evaluation, and control of those environmental factors or stresses arising in or from the workplace, which may cause sickness, impaired health and well-being,

Neck Pain in Pharmacists The work of Plagakis (2010) reports that his time spent working as a pharmacist had ultimately resulted in his neck being bent downward. He reports that he experienced extreme pain in 2009 beginning with discomfort across his shoulders and neck. Plagakis reports that he had to enter physical therapy to combat the pain and bent posture. The study reported by Markotic-Bogavcic (2012) reports the study objective of
