Hierarchy of hazard control is a system used in industry to prioritize ... Physical removal of the hazard is the most effective hazard control. [5] For example, if ...
Engineering controls is the third of five members of the hierarchy of hazard controls, which orders control strategies by their feasibility and effectiveness. Engineering controls are preferred over administrative controls and personal protective equipment (PPE) because they are designed to remove the hazard at the source, before it comes in ...
This electrical hazard safety sign used in Germany is an example of an administrative control.. Administrative controls are training, procedure, policy, or shift designs that lessen the threat of a hazard to an individual. [1]
Hazard elimination is a hazard control strategy based on completely removing a material or process causing a hazard. Elimination is the most effective of the five members of the hierarchy of hazard controls in protecting workers, and where possible should be implemented before all other control methods.
Hazard substitution is a hazard control strategy in which a material or process is replaced with another that is less hazardous. Substitution is the second most effective of the five members of the hierarchy of hazard controls in protecting workers, after elimination .
When engineering controls are implemented, there is a physical change made to the work environment that will eliminate or reduce the risk to chemical exposure. An example of engineering controls is the enclosure or isolation of the process that creates the chemical hazard. [16]
Hierarchy of hazard controls: Those hazard control methods at the top of the graphic are potentially more effective and protective than those at the bottom. Following this hierarchy of controls normally leads to the implementation of inherently safer systems, where the risk of illness or injury has been substantially reduced. [40]
A control is any process for controlling a hazard. The job is broken down into its component steps. Then, for each step, hazards are identified. Finally, for each hazard identified, controls are listed. In the example below, the hazards are analyzed for the task of erecting scaffolding and welding lifting lugs:
