Common use of Hierarchy of Controls Clause in Contracts

Hierarchy of Controls. Elimination is seen as the most effective method of hazard control. An example of elimination in this project was having recyclable materials from the demolished portion of the building sorted off-site by the recycling sub. This eliminated worker risk of contact with objects and equipment as well as overexertion in holding, carrying, or wielding. Using an inert gas system that did not require dangerous electrical currents also eliminated the risk of electrocution for the workers installing the system. If elimination is not a possibility to solve a safety problem, the next desirable alternative is substitution, which could mean substituting in a safer material or a safer process. There were no notable examples of substitution in this project. Engineering control is the third most effective form of hazard control. If the hazard cannot feasibly be eliminated or substituted, and engineering control reduces worker exposure to the hazard. Guard rails and a platform were installed on top of the gas tanks for workers installing actuator valves. This greatly reduced the fall risk for workers working on top of the tanks. Using a mechanical lift to install overhead pipes is also an example of an engineering control. Administrative controls such as worker training and pick plans were used extensively throughout the project. The least effective form of hazard protection is Personal Protective Equipment (PPE), which was a common response for many tasks throughout the project where the above mentioned controls would not have been possible or economically feasible.

Hierarchy of Controls. Elimination is seen as the most effective method of hazard control. An example of elimination in this project was having recyclable materials from benching the demolished portion sides of the building sorted off-site by excavation area to prevent instances where the recycling subsides of the excavated area could collapse on a worker. This Using a lift when installing the stone façade also eliminated worker risk of contact with objects and equipment exhaustion as well as overexertion in holding, carrying, or wielding. Using an inert gas system that did not require dangerous electrical currents also eliminated the risk of electrocution for opposed to having the workers installing lift and lower the systemmaterials by hand. If elimination is not a possibility to solve a safety problem, the next desirable alternative is substitution, which could mean substituting in a safer material or a safer process. There were no notable examples of substitution in this project. Engineering control is the third most effective form of hazard control. If the hazard cannot feasibly be eliminated or substituted, and an engineering control reduces worker exposure to the hazard. Guard rails and a platform were installed on top near the perimeter of the gas tanks for excavated area as a form of engineering control to prevent workers installing actuator valvesfalling in. This greatly reduced Tag lines were also used with the fall risk for workers working on top of the tanks. Using a mechanical lift crane in order to install overhead pipes is also an example of an engineering controlcontrol they payload while it was being hoisted up. Administrative controls such as worker training and pick plans were used extensively throughout the project. The least effective form of hazard protection is Personal Protective Equipment (PPE), which was a common response for many tasks throughout the project where the above mentioned controls would not have been possible or economically feasible. Scaffolding was used for workers constructing walls in response to a potential fall hazard. Fall arrest systems were used for workers near the leading edge of the deck and for those setting and connecting steel beams.
