What are the 5 hierarchy of control?
NIOSH defines five rungs of the Hierarchy of Controls: elimination, substitution, engineering controls, administrative controls and personal protective equipment.
What are some examples of hierarchy of control?
Common examples include mechanical guards, interlocking systems and safeguarding devices such as fences, safety mats and two-hand controls. While engineering controls aren’t as protective as elimination or substitution, they still control exposure at the source of the hazard, before it comes into contact with workers.
What is the purpose of the hierarchy of control?
Traditionally, a hierarchy of controls has been used as a means of determining how to implement feasible and effective control solutions. The idea behind this hierarchy is that the control methods at the top of graphic are potentially more effective and protective than those at the bottom.
What are Level 2 controls?
Level 2 controls Isolate – As much as possible, separate the hazard or hazardous work practice from people by distance or using barriers, such as placing guards around moving parts of machinery. Engineering controls – These are physical control measures, such as guarding or using a trolley to lift heavy loads.
What are the 3 stages of the hierarchy of measures?
Hierarchy of Control Measures: Working at Height
- Level 1: Avoiding Work at Height.
- Level 2: Preventing Falls Through the Existing Workplace.
- Level 3: Preventing Falls Through Collective Equipment.
- Level 4: Preventing Falls Through PPE.
- Level 5: Minimising Distance Through Collective Equipment.
Why is PPE at the bottom of the hierarchy of controls?
And why is PPE at the bottom of the hierarchy of controls? It’s at the bottom of the hierarchy of controls because it is effectively letting the hazard exist in the workplace. You are exposing the person, so the hazard and you are wrapping them up in some way to protect them from that hazard.
What is substitution in hierarchy of control?
Substitution. Substitution is a form of hazard elimination, and the two may be combined on some hierarchy of hazard control lists. Substitution involves replacing something that is hazardous, with something that is not hazardous. A typical example is replacing a solvent-based paint with a water-based paint.
Where does the hierarchy of control come from?
The hierarchy is a strategy that originates from the NIOSH Prevention through Design national initiative to determine how to implement effective hazard control solutions.
What is the hierarchy of control for work at height?
*Hierarchy of control measure when working at height: Avoid working at height if possible. Use an existing safe place of work. Provide work equipment to prevent falls.
What are the 4 hierarchy of measures in manual handling?
first : avoid hazardous manual handling operations so far as is reasonably practicable; second : assess any hazardous manual handling operations that cannot be avoided; and. third: reduce the risk of injury so far as is reasonably practicable.
