Scaffolding Part 2

Scaffolding Part 2 Self Inspection Checklist

Guidelines: This checklist covers regulations issued by the U.S. Department of Labor, Occupational Safety and Health Administration (OSHA) under subpart L of the construction standards 29 CFR 1926.451, 1926.452, and 1926.454. It applies to erecting temporary scaffolding at worksites associated with construction, alteration, demolition, or repair work, including painting and decorating. It covers fall protection, falling object protection, pole scaffolds, tube and coupler scaffolds, fabricated frame scaffolds, horse scaffolds, ladder jack scaffolds, and training. This checklist does not cover additional requirements for plasterers', decorators', and large-area scaffolds; bricklayers' square scaffolds; form scaffolds and carpenters' bracket scaffolds; roof bracket scaffolds; outrigger scaffolds; pump jack scaffolds; window jack scaffolds; crawling boards (chicken ladders); step, platform, and trestle ladder scaffolds; single-point adjustable suspension scaffolds; two-point adjustable suspension scaffolds (swing stages); multi-point adjustable suspension scaffolds, stonesetters' multi-point adjustable suspension scaffolds, and masons' multi-point adjustable suspension scaffolds; catenary scaffolds; float (ship) scaffolds; interior hung scaffolds; needle beam scaffolds; multi-level suspended scaffolds; mobile scaffolds; repair bracket scaffolds; stilts; and aerial lifts. Please consult the OSHA standards 29 CFR 1926.451, 1926.452 and 1926.453 for these types of scaffolds. The regulations cited apply only to private employers and their employees, unless adopted by a State agency and applied to other groups such as public employees. A yes answer to a question indicates that this portion of the inspection complies with the OSHA or U.S. Environmental Protection Agency (EPA standard), or with a nonregulatory recommendation. This checklist should be used with the Scaffolding-Part 1 checklist. Subpart L of the OSHA construction standards includes appendixes that give useful information on scaffold specifications. Definitions of terms in bold type are provided at the end of the checklist.

Definitions:
 

Bearer (putlog): a horizontal transverse scaffold member supported by ledgers or runners. The scaffold platform rests on the bearer, and the bearer joins scaffold uprights, posts, poles, and similar members.

Brace: a rigid connection that holds one scaffold member in a fixed position with respect to another member, or to a building or structure.

Competent person: one who can identify hazards in the work area or conditions that are unsanitary, hazardous, or dangerous, and who has the authority to take prompt corrective measures to eliminate them.

Coupler: a device for locking together the tubes of a tube and coupler scaffold.

Gusset: a metal plate used for connections.

Personal fall arrest system: a system used to stop an employee's fall. It consists of an anchorage, connectors, a body belt or body harness, and may include a lanyard, deceleration device, lifeline, or combinations of these.

Lifeline: a component consisting of a flexible line that connects to an anchorage at one end to hang vertically (vertical lifeline), or that connects to anchorages at both ends to stretch horizontally (horizontal lifeline). The lifeline serves connects other components of a personal fall arrest system to the anchorage.

Qualified: a person who, by a recognized degree, certificate, or professional standing; or by extensive knowledge, training, and experience, has successfully demonstrated an ability to solve problems related to a subject matter, work, or project.

Runner (ledger or ribbon): the lengthwise horizontal spacing or bracing member that support the bearers.

Supported scaffold: one or more platforms supported by outrigger beams, brackets, poles, legs, uprights, posts, frames, or similar rigid support.
