The hierarchy of control measures is a tool used to control risks in the workplace, where all possible control options are ranked by order of effectiveness. The hierarchy of control is a useful tool, as the order tells you which of types of control measure provides a better level of risk control. The higher in the hierachy of control, the better and more reliable the control is. Preferably use control measures which are presented first, so far as is reasonably practicable. The reason that the first three are more effective is because they are examples of safe place strategies, whereas the last three examples of safe person strategies.

Eliminate is where the job is redesigned so as to remove the hazard. However, the alternative methode should not lead to less acceptable product or less effective process. It is started from the design phase of the project, so far as is reasobly practicable, by providing the proper technology OR creating the regulation from the authority to avoid working at high risk. An example would be the Work at Height Regulation which require us to avoid working at height, so far as is reasonably practicable. An example of this would be window cleaners who now use a telescopic pole to clean first floor window from the ground floor.
If Hazard elimination is not succesful or not practicable, the next control measure is:
Reduce: a good example would be the use of reduced time exposure when using vibrating tools or with significant problems. Substitution replacing the material or process with less hazardous one. For example, a pathogenic organism could be replaced by a non pathogenic strain of organism. Change the use of powder for the liquid alternative.
If no suitable practical replacement is available, the next control measure is:
Isolation: physically separating the hazards from operator by methods such as enclosing or guarding dangerous items of machinery, or the use of edge protection when working at height.
Controls:
Engineering Controls installing or using additional machinery, such as local exhaust ventilation, to control the risk
Safe System of Work: an example of this could include the prohibtion of eating, dringking and smoking in the work places, the provisions of training and the performance of risk assesment.
Personal Protective Equipment (PPE): this is the last resort. PPE may be used as a temporary control measure until other alternative are installed.
In most cases a combination of engineering controls, administrative procedure and PPE are choosen to control the risks. Where PPE is the main control method it should be (where practical) used in conjunction with another method of PPE and safe work practices.
Discipline: this involve the communication of clear safety rules, use of safety signs to remind people of site rules and manager/supervisor setting a good example. Ultimately, discipline involve resorces to the company’s disciplinary procedures.
