Common use of Hierarchy of Controls Clause in Contracts

Hierarchy of Controls. Elimination is considered to be the most effective form of hazard control. There are several instances in this project where elimination was used. Over-excavating and benching the sides of the excavation area to give workers more room to move and work also prevented any instances of cave-ins where workers could be struck, caught, or crushed by collapsing structures, equipment, or materials. Assembly of the exterior frame was done flat on the finished interior deck. This also eliminated the risk of being struck, caught, or crushed in a collapsing structure. Using pre-fabricated roof trusses eliminated several hazards associated with constructing the trusses at roof height. Installation using a small crane eliminated the risk of workers overexerting themselves lifting the trusses into place manually. 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. When installing the ▇▇▇▇▇ ends and interior trusses, blocking was installed on the ground and the trusses were connected and secured at height using a crane. Engineering control is the third most effective form of hazard control. A telescoping forklift was used as an engineering control to lift materials onto the roof. Lifting the materials by hand poses a risk of overexertion. Administrative controls such as communication and training were used extensively during the assembly of the exterior frame and the hoisting of roof materials. 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. PPE such as gloves, sturdy shoes, and safety glasses were absolutely required for all workers.

Hierarchy of Controls. Elimination is considered to be seen as the most effective form method of hazard control. There are several instances An example of elimination in this project where elimination was usedusing directional boring to install the gas pipeline instead of trenching. Over-excavating While the original bid documents and benching pricing estimates called for trenching, the sides of CM felt that directional boring would be more efficient when installing among the excavation area old utilities and safer since the installation site was near traffic. Directional boring does not require a trench to give be dug, so there was no longer a risk for workers more room in a trench to move and work also prevented any instances of cave-ins where workers could be struck, caughtcaught in, or crushed by collapsing structures, equipment, or materials. Assembly of the exterior frame was done flat on the finished interior deck. This also eliminated the risk of being struck, caught, or crushed in a collapsing structure. Using pre-fabricated roof trusses eliminated several hazards associated with constructing the trusses at roof height. Installation using a small crane eliminated the risk of workers overexerting themselves lifting the trusses into place manually. 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. When installing Having the ▇▇▇▇▇ ends and interior trusses, blocking was installed work on the ground six-lane highway done at night was safer for workers since traffic was lighter and an extra lane could be closed as a safety barrier between the traffic and the trusses were connected and secured at height using a craneworkers. Another example of substitution in this project was pot-holing to locate utilities instead of hand-digging. This reduced worker risk of being exposed to underground electrical wires. Engineering control is the third most effective form of hazard control. A telescoping forklift was used as an If the hazard cannot feasibly be eliminated or substituted, and engineering control reduces worker exposure to lift materials onto the roofhazard. Lifting A traffic barrier between workers and traffic and a trench box used in utility excavation are two examples of engineering controls implemented by the materials by hand poses a risk of overexertion. project management team and CM respectively Administrative controls such as communication and training were used extensively during the assembly all stages of the exterior frame project. Administrative controls for the six-lane highway were the substance of the MOT plan and included barricades, high-visibility clothing for workers, signage, lights, and flagmen. Safety training was the hoisting of roof materialsprimary administrative control used for utility work. Workers were trained in how to properly excavate using a backhoe, directionally bore the gas lines, lift and place pipes with the backhoe, and weld or connect the pipes together in the trench. 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. PPE such as gloves, sturdy shoes, and safety glasses were absolutely required for all workersworkers on the site, along with high-visibility vests and leggings for nighttime workers on the highway.

Hierarchy of Controls. Elimination is considered to be the most effective form of hazard control, which makes it the most desirable from an OSH standpoint. There are several instances in two examples of elimination being used during this project where elimination was usedproject. OverHaving workers attach the pre-excavating cast panels from the second floor deck instead of from lifts and benching ladders eliminated the sides fall hazard. The design of the excavation area to give workers more room to move and work also prevented any instances of cave-ins where workers could be struck, caught, or crushed by collapsing structures, equipment, or materials. Assembly of the exterior frame was done flat on the finished interior deck. This roof screen also eliminated the risk of being struck, caught, or crushed in a collapsing structure. Using pre-fabricated roof trusses eliminated several hazards associated with constructing fall hazard by serving as fall protection for workers working on the trusses at roof height. Installation using a small crane eliminated the risk of workers overexerting themselves lifting the trusses into place manuallyrooftop HVAC and drain systems. 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. When installing One example of this was the ▇▇▇▇▇ ends and interior trusses, blocking was installed on the ground and the trusses were connected and secured at height using designer’s decision to use a cranePVC membrane system instead of built-up bitumen roofing. This decision limited worker exposure to harmful substances or environments. Engineering control is the third most effective form of hazard control. A telescoping forklift was used Perimeter cables were installed along the edge of the roof as an engineering control fall protection. Workers on the roof were required to lift materials onto tie off to these cables while working outside of the roof. Lifting the materials by hand poses a risk of overexertionroof screen. Administrative controls such as communication and training were used extensively during throughout the assembly of project. When the exterior frame pre-cast panels were being installed via crane, the nearby area was roped off and a spotter with a bullhorn was used for the hoisting of blind lifts. Workers were trained to properly install the roof materialsscreens and avoid overexertion and bodily reactions. 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. Aside from typical worker PPE such as gloves, sturdy shoeshardhats, and safety glasses were absolutely required for all workersboots, the most prevalent form of PPE used during this project was a fall arrest system where workers tied off to the perimeter cable installed on the roof during roof deck construction.

Hierarchy of Controls. Elimination is considered to be the most effective form An example of hazard control. There are several instances elimination in this project where elimination was usedusing pre-fabricated roof trusses instead of stick- building. Over-excavating This saved time, money, and the amount of instances the workers would need to be at height installing the trusses. Overexcavating, early backfilling, and benching the sides of the excavation area to give also gave workers more room to move and work also prevented any instances of cave-ins where workers could be struck, caught, or crushed by collapsing structures, equipment, or materials. Assembly of the exterior frame was done flat on the finished interior deck. This also eliminated the risk of being struck, caught, or crushed in a collapsing structure. Using pre-fabricated roof trusses eliminated several hazards associated with constructing working in a deep confined area. Building the trusses at roof height. Installation using a small crane exterior frame flat also eliminated the risk of workers overexerting themselves lifting the trusses into place manuallyneed to assemble it at height. 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. When installing In the ▇▇▇▇▇ ends and interior trussespre- construction phase, blocking the constructor was installed on able to find lighter roofing material that came in larger rolls. Substituting a lighter material meant that workers did not have to lift as much weight up onto the ground and the trusses roof. Having larger rolls also meant that workers were connected and secured at height using a craneable to make fewer trips. Engineering control is the third most effective form of hazard control. A telescoping forklift There are several examples of engineering controls being used in this project. The constructor decided to backfill 3-4 feet of the excavation early so the workers were not working at full height. Another example was the orange painted barrier installed six feet from the leading edge of the excavation area. This was to prevent workers from stumbling into the pit while working on the exterior frame. Breakaway fall arrest anchor points on the roof were also engineering controls used as an engineering control to lift materials onto by the roof. Lifting the materials by hand poses a risk of overexertionconstructor. Administrative controls such as training and communication and training were used extensively by the workers during the assembly of the pre-cast concrete basement, construction of the exterior frame frame, and the hoisting of roof materials. 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. PPE such as gloves, sturdy shoes, safety glasses, and safety glasses respirators (if applicable) were absolutely required for all workers.

There are several instances An example of elimination in this project where elimination was used. Overhaving the head walls fabricated off-excavating and benching the sides of the excavation area to give workers more room to move and work also prevented any instances of cave-ins where workers could be struck, caught, or crushed by collapsing structures, equipment, or materials. Assembly of the exterior frame was done flat on the finished interior decksite. This also eliminated the risk of being struck, caught, or crushed in a collapsing structure. Using pre-fabricated roof trusses eliminated several hazards associated with constructing the trusses at roof height. Installation using a small crane eliminated the risk of workers overexerting themselves lifting coming into contact with objects and equipment that is usually present during head wall assembly. Elimination was also used when the trusses into place manuallyconstructor decided to have the fall protection installed on the ground. This eliminated the need for workers to be working at heights unrestrained for any period of time. 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 several examples of substitution in this project. When installing erecting the ▇▇▇▇▇ ends and interior trussessteel structure, blocking was installed the constructor decided to have two columns attached to one beam while on the ground and have the trusses unit lifted into place with a tower crane. This process required less lifts, so the probability of a worker being struck was much lower. Connecting the columns and beams on the ground also meant fewer connections needed to be made at height. For the interior systems, the rough-ins were done at an off-site warehouse and delivered to the site. This saved time on construction and also lowered worker exposure to the equipment and materials used to do the rough-in. This hazard was also considered when the constructor decided to have the overhead interior systems connected and secured at height using a craneon the ground so fewer pieces had to be lifted into place. Engineering control is the third most effective form of hazard control. A telescoping forklift was used as an If the hazard cannot feasibly be eliminated or substituted, and engineering control reduces worker exposure to lift materials onto the roofhazard. Lifting Tag lines were used during crane lifts to reduce the materials likelihood of a worker being struck by hand poses object or equipment. The project management team decided to have d-rings tied into the steel deck, which reduced the probability of a risk of overexertionworker falling to a lower level. Shared racks were required for the interior systems, which reduced worker contact with objects and equipment. Parts required for installation were required to be delivered on carts that would fit on the lift, in order to reduce worker overexertion in lifting. Administrative controls such as communication worker training and training pick plans were used extensively during throughout the assembly of the exterior frame and the hoisting of roof materialsproject.

Engineering control is the third most effective form of hazard control. A telescoping forklift was used as If the hazard cannot feasibly be eliminated or substituted, an engineering control reduces worker exposure to lift materials onto the roofhazard. Lifting The assembled steel frame was delivered to the materials site on a flatbed truck. The area where the truck would back in to was roped off and controlled by hand poses a risk of overexertionflagmen, which was an engineering control from the owner. Mechanical lifts and engineered scaffolds for installing the economizer were engineering controls implemented by the constructor to reduce worker fall risks. Administrative controls such are the next most effective hazard control if engineering controls are not feasible.
