Industrial hygiene anticipation

Industrial Hygiene Reviews These reviews evaluate the potential of a process to cause harm to the health of people. It is the science of the anticipation, recognition, evaluation, and control of health hazards in the environment. It usually deals with chronic, not acute, releases and is involved with toxicity. 

Industrial hygiene The science and art devoted to the anticipation, recognition, evaluation, and control of those environmental factors or stresses arising from the workplace which cause sickness, impaired health and well-being, or significant discomfort and inefficiency among workers or among the citizens of the community. 

Frequently industrial hygiene analyses require the identification of unknown sample components. One of the most widely employed methods for this purpose is coupled gas chromatography/ mass spectrometry (GC/MS). With respect to interface with mass spectrometry, HPLC presently suffers a disadvantage in comparison to GC because instrumentation for routine application of HPLC/MS techniques is not available in many analytical chemistry laboratories (3). It is, however, anticipated that HPLC/MS systems will be more readily available in the future ( 5, 6, 1, 8). HPLC will then become an even more powerful analytical tool for use in occupational health chemistry. It is also important to note that conventional HPLC is presently adaptable to effective compound identification procedures other than direct mass spectrometry interface. These include relatively simple procedures for the recovery of sample components from column eluate as well as stop-flow techniques. Following recovery, a separated sample component may be subjected to, for example, direct probe mass spectrometry infra-red (IR), ultraviolet (UV), and visible spectrophotometry and fluorescence spectroscopy. The stopped flow technique may be used to obtain a fluorescence or a UV absorbance spectrum of a particular component as it elutes from the column. Such spectra can frequently be used to determine specific properties of the component for assistance in compound identification (9). 

Industrial hygiene is a professional field with responsibility related to protecting the health of workers, and protecting communities that may be impacted by work-related exposures. Historically, industrial hygiene has been described as the anticipation, recognition, evaluation, and control of workplace...

ERPGs are widely used. As defined by J7ie American Industrial Hygiene Association, ERPGs (AIHA, 2009) provide estimates for concentration ranges where a person may reasonably anticipate observing adverse effects as a consequence of exposure to the chemical in question. ... 

Due to the containerized nature of limited hazardous material stored in the HCF, the small quantities that are used in HCF processes, and the well-confined and well-ventilated process areas where hazardous materials are used, workers are not expected to receive any measurable occupational exposure to chemicals. If exposure is anticipated or suspected, SNL industrial hygiene personnel will assist in establishing the potential for exposure or in estimating exposures and will make recommendations to implement any necessary corrective actions. There have been no chemical over-exposures associated with past activities in the HCF.

Industrial hygiene has most often been described as the art and science devoted to the recognition, evaluation, and control of workplace health hazards. In addition to these three tenets, it has been suggested that we add a fourth, anticipation. We must be careful here to avoid expecting the expected. Emphasis on the anticipation of workplace...
