Suspension ropes must be shielded from heat-producing processes. Suspension ropes supporting adjustable suspension scaffolds must be a diameter large enough to provide sufficient surface area for the functioning of brake and hoist mechanisms. Įmployers must replace wire rope when the following conditions exist: kinks six randomly broken wires in one rope lay or three broken wires in one strand in one lay one third of the original diameter of the outside wires is lost heat damage evidence that the secondary brake has engaged the rope and any other physical damage that impairs the function and strength of the rope. ĭrum hoists must contain no less than four wraps of the rope at the lowest point. 12 frames 24 Cross Braces 8 Wooden Hook framed planks Also have tube and clamp scaffold for sale, as well as extension.

Emergency escape and rescue devices must not be used as working platforms, unless designed to function as suspension scaffolds and emergency systems.When lanyards are connected to horizontal lifelines or structural members on single-point or two-point adjustable scaffolds, the scaffold must have additional independent support lines equal in number and strength to the suspension lines and have automatic locking devices.When using direct access, the surface must not be more than 24 inches (61 cm) above or 14 inches (36 cm) horizontally from the surface.When scaffold platforms are more than 24 inches (61 cm) above or below a point of access, ladders, ramps, walkways, or similar surfaces must be used.A competent person must inspect ropes for defects prior to each workshift and after every occurrence that could affect a rope's integrity.Guardrails, a personal fall-arrest system, or both must protect each employee more than 10 feet (3.1 m) above a lower level from falling.All suspension scaffolds must be tied or otherwise secured to prevent them from swaying, as determined by a competent person.A competent person must evaluate all direct connections prior to use to confirm that the supporting surfaces are able to support the imposed load.All support devices must rest on surfaces capable of supporting at least four times the load imposed on them by the scaffold when operating at the rated load of the hoist, or at least one-and-a-half times the load imposed on them by the scaffold at the stall capacity of the hoist, whichever is greater.Employers must ensure that all employees are trained to recognize the hazards associated with the type of scaffold being used.Do not use scaffold planks as a base to stack materials, or as ramps or temporary roadways.Some of the requirements for all types of suspension scaffolds include:.Do not paint as the paint can conceal defects. Stack planks on a firm level surface to prevent warping.How should decking be stored?

Inspect planks on a regular basis while on the scaffold.Platform decks should be slip-resistant and should not accumulate water. Clean ice, snow, oil and grease off planks.Damage can occur if the platforms are dropped or thrown. Check hooks and hardware of prefabricated platform units regularly for looseness, distortion and cracks.Discard immediately any planks showing these or other defects. Splits wider than 10 mm (3/8 in), lengthwise closer than 75 mm (3 in.) to the edge of the plank, or lengthwise longer than ½ the length of the plank are not acceptable.
