The enforcement policy is due to come into effect from July 26th this year, through November 8th 2013 for construction cranes with proximity alarms or insulating links.
The policy concerns 29 CFR 1926 Subpart CC’s recognition of these devices as alternative methods for warning the operator of his proximity to power lines or to insulate against electricity. The devices must be “listed, labelled or accepted by a nationally recognised testing laboratory in accordance with 29 CFR 1910.7.”
However a memo from Jim Maddux, director of OSHA’s directorate of construction to regional administrators written late last month says that from July 26th – i.e next week, no current proximity alarm or insulating link/device meets the requirement, as no nationally recognised testing laboratory is recognised by OSHA as able to perform the required testing.
The temporary enforcement policy says employers may not rely on any proximity alarm to comply with 29 CFR 1926 Subpart CC. A company using a proximity alarm will not be cited though as long as it employs an additional measure, such as a dedicated spotter or range control warning device. A similar approach will be applied for insulating links/devices.
