Prevention through design safety practice

Chapter 20, Applied Ergonomics Significance and Opportunity, and Chapter 21, On Quality Management and the Practice of Safety, address the design, engineering, and risk assessment aspects that are fundamental in those endeavors. Comments are included in Chapter 18, Prevention through Design The Standard, on the extensive involvement at the National Institute for Safety and Health (NIOSH) on its PtD initiative. 

You should approach each category of hazard with the intention of preventing it. If total prevention is not feasible, you should control the hazard as completely as possible through equipment design. To the extent that potential exposure exists despite the designed controls, then you should use safety rules, work practices, and other administrative measures to control that exposure. Finally, you may need to use personal protective clothing and other equipment to further minimize levels of employee exposure [2],...
