What Is Hierarchy of Control ?<br />Many employers start from the bottom of the list when considering options.<br />Some think that it is cheaper and/or simpler to change worker behavior or give them some protection against the hazard that to fix the cause of the problem<br />In the long run this approach costs more in time and money and is less effective.<br />
Elimination<br />Options which get rid of the hazard altogether. The best way to eliminate the risk is to completely remove the hazard.<br />For example :<br />repair damaged equipment promptly<br />move a noisy machine from a quiet area.<br />ensure new equipment meets the ergonomic needs of users<br />
Substitution<br />Replacing a hazardous substance or work practice with a less hazardous one<br />For example :<br />a telephone hand set can be replaced with a head set where there is constant use of the telephone<br />substituting a smaller package or container to reduce the risk of manual handling injuries such as back strain<br />substituting a hazardous chemical with a less dangerous one<br />
Isolation<br />Isolate the hazard by controlling or guarding it.<br />place hazardous electrical plant in enclosures with restricted access<br />place out-of-service tags on plant.<br />
Engineering Controls<br />The provision of mechanical aids, barriers, machine guarding, ventilation or insulation to isolate a hazard from employees.<br />For example;<br />electrical cut out switches<br />isolating copying equipment in soundproof and ventilated rooms<br />using trolleys or mechanical lifting aids<br />changing bench heights to reduce bending<br />
Administrative Controls<br />Establishing policies, procedures and work practices designed to reduce a worker’s exposure to a risk. It can also include the provision of specific training and supervision.<br />For example:<br />increasing job variety and introducing job rotation.<br />redesigning jobs<br />training and education to learn how to be professional workers<br />
Personal Protective Equipment (PPE)<br />Covering and protecting a worker’s body from hazards. It can be used as a short-term control measure until a higher order” control has been provided, or to supplement it. The employer would also have to provide training for workers required to use it, and the employee would have a responsibility to use it properly. <br />Some examples of PPE are:<br />Use ear plugs in noisy areas<br />Use eye protection when working with chemicals<br />Use gloves to protect against infection<br />
Demonstrate the proper and save methods in deploying portable fire extinguisher<br />
