Dear Mr. Bilodeau:
This is in response to your February 9 letter requesting an interpretation of an Occupational Safety and Health Administration (OSHA) standard addressing radio anti-two-block systems on cranes.
As you may know, OSHA does not approve nor endorse products. The variable working conditions at job sites and possible alterations or misapplication of an otherwise safe product could easily create a hazardous condition beyond the control of the manufacturer. However, when provided with adequate information, OSHA can offer an opinion as to whether or not the product affords compliance with certain regulations. We have reviewed the Radio Anti-Two-Block System information contained in your letter, and it appears that if the system automatically shuts down the hoist and/or boom lift mechanism in the event of a two-blocking incident, it would meet OSHA's anti-two-block requirements for cranes used to suspend personnel platforms.
If we can be of any further assistance, please contact me or Mr. Dale R. Cavanaugh of my staff at (202) 219-8136.
