ABSTRACT
Chemicals are used extensively and are an integral part of industry operations and our daily lives. The chemical products discussed throughout this book have uses that are beneficial and capable of enhancing the quality of life. However, these same chemicals can produce life-changing illnesses and even death. A substantial cadre of products are produced from chemicals including detergents, plastics, paints, and pharmaceutical, and the list goes on. Although some of these chemicals appear to be harmless because of their beneficial use, they can result in injuries and illness upon coming in contact with humans. On the other hand, some health effects are not immediate and only may occur after prolonged exposure. Raw materials from many sources are converted by the chemical industry into substances that are used in the production of products such as cosmetics, detergents, soaps, drugs, dye pigments, explosives, fertilizers, and a host of other useful products. These resultant products or the production process can create exposure hazards for workers and users. Chemical substances that have the capability to result in a physical or health hazard to humans are considered hazardous. Chemical substances due to their properties may be toxic, explosive, flammable, reactive, oxidizing, or corrosive. Exposure to these substances by the different routes of entry including inhalation, dermal absorption, or ingestion can lead to adverse health effects.
