Thank you for visiting our site. They can provide a stable work surface for various exterior finishing tasks. The Temper Reusable Anchor has been designed with offset holes in it to protect against splitting of the trusses or rafters below the anchor. Figure 35 - Guardrails protecting window openings. You can choose your own username, password, and security questions; this will help make it easy to remember your account information. Exterior Finishing The exterior finishing phase of residential construction includes a number of activities, such as installing windows, doors, siding, and gutters.
In particular, boom type elevating and rotating aerial work platforms can offer positioning flexibility and provide stable elevated platforms. Anchors with expandable bolts can be placed in holes that have been drilled into the concrete. These cases indicate that engineering services are not always required. This does not mean that fall hazards are no longer present. Ladder jacks provide limited elevation and are primarily used in light applications because of their portability and cost-effectiveness. These anchors can be used with personal fall arrest systems and fall restraint to provide fall protection for workers engaged in this activity.
The anchor provides an economical solution for fall protection during the initial construction stage as well as future roof access and maintenance. Foundation Walls and Formwork In most residential construction, concrete or masonry block is used to create the foundation and the foundation walls of a structure. Anchors Anchors can be added to cured concrete. Installing Roof Trusses Numerous methods can be used to prevent fall-related injuries and fatalities among workers installing roof trusses. The guardrail system on the scaffold can provide fall protection. A ladder jack scaffold consists of a platform resting on brackets attached to a ladder. Bracket Scaffold A bracket scaffold can be attached to the top plate of a structure.
For more details on temporary and permanent bracing of wood frame structures, visit. If installed with a toeboard, guardrail systems can also protect workers on lower levels from falling objects. Antichafe sleeves the green part of the anchor can be used to maintain the integrity of the strap. Exterior bracket scaffolds can also be used for installing roof trusses and other rooftop construction activities. With proper bracing, the frames can be stacked from cellar hole to chimney top. It can be attached to a compatible roof truss either on the roof or while the truss is still on the ground, and the entire installation can be done in less than in a minute. The anchor provides an economical solution for fall protection during the initial construction stage as well as future roof access and maintenance.
In the southwest, roof design loads also include supporting the weight of concrete tiles. This precludes the additional costs of hiring a professional engineer or architect to design and create unique structures to facilitate fall protection. They can provide an anchorage point during the life of the roof. Scaffolds Scaffolds can be used for residential construction workers installing floor joists and floor trusses. Anchors A spreader braces the trusses and distributes arrest forces across several trusses.
Letter to Assistant Secretary of Labor Jeffress: Comment on Fall Protection Standard. Fall protection used to comply with 1926. The worker who fell is shown in Photo 5 demonstrating his height above the ground where he came to rest and reenacting with the other worker how he was rescued. . Figure 6 - A bolt-on anchor attached to a rafter.
Installing Floor Joists and Floor Trusses Floor joists and floor trusses are usually constructed directly over the foundation walls. Thus, the performance target that the manufacturer uses is to bring a 282-lb weight falling 6 ft to a stop within 42 in. These strap anchors can also be poured over with concrete and left in during construction. Figure 23 - Framed walls being erected using a jack. Residential Roof Fall Protection Systems with Temporary Anchors Residential roofing is physically demanding work, often involving heavy lifting, bending and kneeling.
Aerial Lifts Aerial lifts can be ideal equipment for exterior finishing. In some instances, the truss system found in your building may be strong enough to support a fall protection system. Animations were created as a demonstrative aid for those cases in which information was sufficient to describe the structure to which the anchor was attached and the kinematics of the fall. Type of construction: Residential framing, single family home Fall Incident The employee was working on the top plate of a one-story structure during truss erection. When bracket scaffolds are used on the interior of the structure, the exterior wall can limit employee exposures to fall hazards.
These strap anchors can also be poured over with concrete and left in during construction. Figure 20 - Workers using a truss bracket anchor while installing a subfloor. This is the reason the anchors did not fail in the arrested falls. Unlike our Connect Safe Portable Truss Anchors, the Fixed Truss Single Point Anchor is mechanically attached with steel plates and a threaded bolt and nut combination. Figure 10 - An exterior bracket scaffold with guardrails being used to protect workers while weatherproofing. For longer roofs or where a greater range of movement is desired temporary horizontal lifelines are available.
The addition of a toeboard can also prevent objects from falling to lower levels. Some exterior bracket scaffolds can be used as catch platforms to prevent workers from falling six feet to the lower level. These scaffolds can provide access around the perimeter of the structure and can be used by workers while they install carrier beams, floor joists, and floor trusses. Figure 31 - Worker positioning an aerial lift. Safety Net System Safety net systems can be used as fall protection for workers installing roof sheathing. When appropriately installed in accordance with the manufacturer's instructions, these anchors can be used with personal fall arrest systems and fall restraints.
