Let's compare the relative effectiveness of engineering versus management controls to improve job safety and health.
Engineering job safety and health within a company entails forecasting potential hazards that are singular to each job position and then planning how to prevent, minimize, or eliminate them. This is usually done before a company opens its doors for business. During this process, some type of standard operating procedure handbook is designed.
After the company has opened its doors, management control steps in and assigns certain people to oversee and enforce its standard operating procedures in order to maintain job safety and the health of its employees. Sometimes, the people who design or develop the job safety and health protocol will be the same ones who end up managing it.
So you see, there is a difference between the two. The relative effectiveness of engineering insures that a complete, comprehensive job safety program will exist within a company. Management control insures that all rules, laws, regulations, and protocol are followed by each and every employee, and enforces those standard operating procedures when necessary. Adherance to these standards will improve job safety and health within a company.
