Industrial hygiene, term

Check the toxicity of process materials, identify short and long term effects for various modes of entry into the body and different exposure tolerance Identify the relationship between odour and toxicity for all process materials Determine the means for industrial hygiene recognition, evaluation and control Determine relevant physical properties of process materials under all process conditions, check source and reliability of data... 

Of these sources, Kirk-Othmer s Encyclopedia of Chemical Technology is particularly recommended for questions on chemistry and on end uses. For information on properties and on toxicity and handling hazards, Patty s Industrial Hygiene, Material Safety Data Sheets (MSDS), and the Aldrich catalog are very nseful. Questions on industrial chemistry should be directed to Ullman s Encyclopedia of Industrial Chemistry, and the texts by Chenier, Heaton, and White. Hawley s Condensed Chemical Dictionary is valuable as a source for dehnitions of the terms (language) of chemistry. 

The following terms of measurement are commonly used in toxicological testing and in industrial hygiene practice ... 

To put this into practical terms, recall that the only data available to an industrial hygienist are a small fraction of all possible samples no exposure is directly observable. The average of several industrial hygiene samples is a good estimate of the long-term average exposure, but the median and mode of sample data underestimate the median and mode of the true exposures. 

The next step of the risk assessment, led by an industrial hygiene professional, evaluates the likelihood that a person exposed to the identified hazards would experience an effect. It is important to note that even a positive therapeutic effect (e.g., cholesterol-lowering) is considered to be adverse in terms of occupational exposure. The goal is to return the person home in the same condition he/she arrived in. Questions addressed in this part of the risk assessment include ...
