## PUMP JACK/LADDER JACK SCAFFOLDPHOTO COMPLIANCE GUIDEMarch 1998

- John NewquistU.S. Department of Labor-OSHA344 Smoke Tree Business ParkNorth Aurora, IL 60542

**Notes:**
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!
