Background Information Health and Safety

Whatever the material or process, health and safety is vital and must be seen at three levels  

The basic hazards can arise from skin contact, respiration and actual ingestion of the chemicals, and from other effects, such as fire or explosion, that may be caused by inadequate caution in handling some of them. Latest thinking on environmental care also spotlights the potential long-term effect of chemicals such as additives. Alongside extensive research into direct hazards to health, there has also been considerable development of safer forms in which to offer additives, to prevent or control escape into the atmosphere. 

A trend of recent years has been to supply additives processed into safe forms, in pellets, capsules, liquids and masterbatch concentrates and so, for the compounder and processor, the hazards have largely been taken out, but it is still important that they should be aware of them. For most compounders and processors of thermoplastics, the hazard from additives can now be safely contained upstream, during manufacture of the additives. In moulding and fabricating wet polymer systems, such as polyesters and polyurethanes, however, it is essential to take precautions.

Our initial round of interviews in the U.K. nuclear power industry was conducted in July 1999 with the British nuclear safety authorities— the Health and Safety Executive (HSE) Nuclear Installations Inspectorate (Nil)— and the private nuclear generating company in England (British Energy). A second round of interviews was conducted in January 2000 to follow up on open issues. Additional background information was obtained from discussions with trade union representatives and a local U.K. trade press correspondent. The U.K. interviewees were given considerable latitude to describe the process and impacts of industry restructuring in their own terms, in part because a sensitive audit was still pre-decisional at the time of the interviews. 

Three comprehensive books on porous silicon have been published, wherein detailed information can be found related to silicon anodization (Canham 1997 Lehman 2002 Sailor 2012a). The topics covered include dissolution chemistries and the dependences of porosity, pore morphology, and pore size distribution on various parameters (e.g., wafer type/doping, electrolyte composition, current density, time) additionally, different types of electrochemical cells are discussed (Lehman 2002 Sailor 2012a), as well as some of the more practical aspects related to anodization (Sailor 2012a e.g., wafer preparation, equipment and instrumentation, health and safety). The reader is referred to these references for essential background reading. 

The author draws upon his lifetime experience in construction-related health and safety to provide the information and the background material important for a full understanding of the issues involved. The book is aimed at every participant in the construction industry needing information and guidance on current and future best practice. 

Chemical safety is a primary focus of professional industrial hygiene. Most standard chemistry curricula cover background information necessary for chemical health and safety, but do not specifically cite hygiene principles. There is little use of chemical health and safety principles even though they can successfully communicate essential chemical principles. Safety concepts are easily included as a meaningful component of chemical education. Incorporation can be achieved by consistent use of safety concepts coupled with an "introductory" chapter. This paper outlines topics and provides examples that can be integrated throughout a text and/or included in a proposed Chemical Health and Safety chapter. 

This book is intended for chemists, toxicologists, laboratory technicians, manufacturers, safety professionals and government personnel involved in environmental and industrial safety and health matters. The ability to identify the actual manufacturers of hazardous materials is important where detailed background information is required when investigating chemical accidents, exposures, product contamination, faulty labeling and other incidents involving chemicals and their effect on workers or the environment.
