HAZMAT & Hazcom: Hazardous Materials & Chemicals Safe Handling, Storage, Msds, Disposal, Monitoring, Response & Clean up

Hazardous materials and chemicals are ubiquitous as air, carbohydrates, enzymes, lipids, minerals, proteins, vitamins, water and wood. Naturally occurring hazardous materials and chemicals are supplemented by man-made substances. There are about 70,000 chemicals in use with another 500-1000 added each year. Their properties have been harnessed to enhance the quality of life, thus chemicals are found in virtually all work places. Besides the benefits, chemicals also pose dangers to man and the environment.

Society must strike a balance between the benefits and risks of hazardous materials and chemicals. In the workplace it is a management responsibility to ensure practices control the dangers, and it is for employees to collaborate in implementing the agreed procedures. Management also prevent uncontrolled environmental releases and ensure all wastes are disposed of safely and with proper regard for their environmental impact. The aims of this course are to raise awareness and to help participants identify, assess and control the hazards of chemicals and other hazardous materials to permit optimum exploitation whilst minimizing the dangers.

The hazards of chemicals stem from their inherent flammable, explosive, toxic, carcinogenic, corrosive, radioactive or chemical-reactive properties. The effect of exposure on personnel may be acute (fatal) or prolonged that result in an occupational disease or systematic poisoning. However, whether a hazardous properties of the chemical (or mixture of chemicals) the scale involved, the circumstances of handling or use, e.g. provision of control and safety devices, local exhaust ventilation, general ventilation, personal protection, atmospheric monitoring and systems of work generally.

This course is designed to cover occupational, industrial and environmental hazards associated with hazardous materials and chemicals. It includes chemical spills, fires and explosions since they inevitably involve chemical compounds, Further, the course will present information on the nature of hazardous materials and chemicals and help participants reduce or eliminate potential exposure to hazardous materials and chemicals in their work environment.
