Temporary Enforcement Policy for Proximity Alarm and Insulating Link Use with Cranes and Derricks in Construction
On June 25, 2012, I issued a temporary enforcement policy memorandum for the use of proximity alarms and insulating links with cranes and derricks in construction near power lines. This temporary policy was effective July 26, 2012 through November 8, 2013. To date, OSHA is still not aware of any proximity alarms or insulating links which are "listed, labeled or accepted by a Nationally Recognized Testing Laboratory [NRTL]" as the construction cranes and derricks standard, 29 CFR 1926 Subpart CC, requires. OSHA does not anticipate proximity alarms or insulating links/devices which meet these NRTL requirements to be available in the near future.
OSHA plans to propose rulemaking that will permanently resolve this issue. In addition, I intend to publish a new temporary policy memorandum in the coming months which updates the enforcement policy set out in my June 25, 2012 memorandum. In the meantime, I would ask that the Regional Administrators continue to observe the temporary enforcement policy set out in the June 25, 2012 memorandum. The June 25, 2012 memorandum is available on the public website and is attached to this email for your convenience.
