Task Hazard Analysis Guidelines

There are a number of very good books which deal with job analysis methods (e.g., Brannick et al. 2007 Prien et al. 2009 Wilson 2012), and also very good guidelines on how to avoid error in job analysis data (e.g., Morgeson and Campion 1997). In general, the aim of job analysis is to produce two documents, a job description and a person specification. The job description document contains aU of the information relating to a job s roles and tasks, a description of the context within which these are performed, and performance expectations, and benefits. Where appropriate, the job description should also include a specific section on the job safety risks and hazards (see Fig. 3.1 in Chap. 3). The other main document that... 

Chemicals are released into the air from both natural and man-made sources. Inhalation of these pollutants can have adverse effects on human health. Also if these chemicals are taken up by plants and animals, then they enter the food chain and cause additional sources for human exposure. Over the years, major efforts have been made to reduce air pollution. This is a complicated task. It starts with an analysis to determine what chemicals are present in the air, their concentrations, and if exposure to them is hazardous to human health. Then control strategies and human exposure guidelines are prepared for each hazardous chemical. In addition, the WHO continues to carry out similar work for controlling contaminants and preparing safety guidelines for human exposure to pollutants in air, water, food, herbal medicines, etc.
