Presentation on theme: "PUMP JACK/LADDER JACK SCAFFOLD PHOTO COMPLIANCE GUIDE"— Presentation transcript:
1 PUMP JACK/LADDER JACK SCAFFOLD PHOTO COMPLIANCE GUIDE Notes: This manual is a product of the U.S. Department of Labor, Occupational Safety and Health Administration.This guide was created to help the residential construction industry more easily understand the OSHA pump jack and ladder jack standards. Home builders in the west suburban Chicago area told us they had difficulty understanding the scaffold regulations, giving rise to the idea of using photos to communicate the regulations. The photo compliance guide walks the reader through the OSHA pump jack and ladder jack regulations, standard by standard.Thanks go to Aurora Area Office compliance staff Bay Pahati, Dave Morgan, John Maronic, John "Nuke" Newquist for the photographs. Special recognition is given to Nuke for scanning the photos and putting this information together.We strongly encourage the reproduction and use of this document!

3 Note: Strapping was used to hold platforms together. Pumpjack Photo: John Newquist(b)(4): Each scaffold platform shall extend over its end support at least 6 inches.Violation: The right platform is not 6 inches over the pump jack bracket.
4 Photo: Bay Pahati Scaf - 36 (c)(2)(i): Footing shall be capable of preventing displacement. Siding contractor putting a wood pump jack leg onto a welded frame scaffold.Violation: Use of another scaffold as a footing can cause displacement by allowing scaffold planks to shift out from under the left leg resulting in its collapse.
5 Pumpjack - 6 Photo: John Maronic (c)(2)(i): Footing shall be sound, rigid, and capable of supporting the loaded scaffold without settling or displacement.Violation: Soil is undercutting beneath the plywood because it was not compacted and protected from water.
6 Note: Use 3/4 inch plywood at least 12 x 12 inch wide and center the leg in the middle. The plywood should be staked in the ground and the leg secured from lateral movement Pumpjack Photo: John Maronic(wording removed from slide: “Violation: Pieces of scrap lumber used as footing does not provide adequate support.”)(c)(4)(i): Footing shall be level, sound, rigid, and capable of supporting the loaded scaffold without settling or displacement.
7 1926.451(e)(1): Safe access shall be provided to scaffolds. No violation: Ladder arranged so that worker can step onto scaffold directly from the ladder.Note: Fall protection is deficient, no mid rails.Pumpjack Photo: John Maronic
8 Violation: Ends are not guarded on this narrow scaffold. (g)(1): Guardrails are required at all open sides and ends of scaffolds.Violation: Ends are not guarded on this narrow scaffold.Note: Nailing guardrails onto wood poles is not practical for siding.Pumpjack Photo: John Newquist
9 Note: Many Alum-a-pole scaffolds have a gap of 30 inches between the work platforms. This space would need midrail protection.Pumpjack Photo: John Newquist(Wording removed from slide: “No violation: Midrail is half way between.”)(g)(4)(iv): When midrails are used, they shall be installed between the top edge of the guardrail system and the platform surface.

11 No violation: The top is secured by metal bracing. Pumpjack Photo: Bay Pahati(j)(2): Pumpjack poles shall be secured to the structure at the top by the use of rigid triangular bracing or equivalent.No violation: The top is secured by metal bracing.
12 (j)(2): Pumpjack poles shall be secured to the structure at the bottom by the rigid triangular bracing or equivalent.No violation: Pump jack pole is secured to mudsill of 3/4 inch plywood which is staked into the ground.Pumpjack Photo: John Newquist
13 1926.452(j)(2): Poles shall be secured at the top by rigid triangular bracing or equivalent. Note: Aurora, Illinois OSHA office recommendation is that play is no more than 3/4 inch in either direction. Also, wood gusset is to be 3/4 inch thick plywood, 18 inches wide, 5' to 8' in length, secured with 4 sixteen penny nails, and nailed through roof deck into truss/rafter.Pumpjack - 9 Photo: John Newquist(Wording removed from slide: “Violation: Too much play in plywood laterally to be considered rigid.”)
14 (j)(3): When work benches are used for fall protection, they must meet requirements of (g):No violation: No midrail is needed because gap between platforms is 23 inches. The work bench can serve as a top rail because the vertical distance from the platform is 23 inches inch thick platform inch horizontal plank width = 39 inches.Pumpjack Photo: John Newquist
15 (j)(3): Workbench may be used as a top rail if it meets the requirements for guardrails in (g)(4).Note: Platform must be secured to meet guardrail strength of 200 lbs.Pumpjack Photo: John Newquist(Wording removed from slide: “No violation: Platform vertical distance is 24 inches + 4 inch thick bench + 12 inch horizontal work bench distance = 40 inches for equivalent top rail protection. 24 inch gap is acceptable midrail opening.”)
16 No violation: Seams are parallel to the bracket. (j)(6): When wood poles are constructed of two continuous lengths, they shall be joined together with the seam parallel to the bracket.No violation: Seams are parallel to the bracket.Pumpjack Photo: John Newquist
17 Violation: No mending plate at the splice. (j)(3): When two by fours are spliced together to make a pole, mending plates shall be installed at all splices to develop the full strength of the member.Violation: No mending plate at the splice.Pumpjack Photo: John Newquist
18 No violation: Scaffold is within 14 inches from the building. (b)(3): Scaffold platform must be within 14 inches to the structure.No violation: Scaffold is within 14 inches from the building.(e)(1): Safe access to scaffold shall be providedViolation: Safe access to scaffold not provided.Note: Access is poor.Ladder jack Photo: Bay Pahati
