Eaton Recalls 30-60A Heavy-Duty Safety Disconnect Switches

July 19, 2018

ISSUE: We have been notified that certain types of Eaton Heavy-Duty Safety Disconnect Switches (30 and 60 Amp) may have a serious manufacturing defect. The switch may fail to disconnect power even when the handle is pulled down to the off position. It should NOT be used for LOTO and will have to be replaced or repaired. At this point, the focus is identifying if and where we may have these switches. Repairs will be effected in a planned fashion through Facilities.   Detailed information can be found here: Eaton link ACTION: Be on the lookout for (BOLO) any 30 or 60 Amp Eaton Switch that has a similar appearance to the one in the attached photo. If found, email electricalsafety@lbl.gov with information about the location. We will schedule an immediate visit by a qualified person to determine whether this switch is subject to the recall. DO NOT RELY on any 30 or 60 A switch for LOTO unless you are certain it is not part of the affected units. Instead, LOTO upstream at the breaker panel.

Extech Recalls Digital Clamp Meters Due to Electrocution Hazard (Multiple Models)

May 30, 2017

The meters can fail to give an accurate voltage reading, resulting in the operator falsely believing the electrical power is low or off, posing an electrocution hazard. Extech received two reports of clamp meters displaying an incorrect voltage reading. No injuries have been reported. Consumers should immediately stop using the recalled digital clamp meters and contact Extech for a free replacement meter. The models include: EX650 and 655 MA160 MA61 MA63 These models are all AC/DC clamp meters, which are electrical testing devices that measure AC/DC voltage, resistance, capacitance, frequency, temperature, continuity, and diode. Serial numbers in the following format are included in the recall: R15XXXXXXX to R17XXXXXXX. Only serial numbers in this range are included in the recall. The “EXTECH” logo and the model number are printed on the front of the unit and the serial number on the back. The digital clamp meters are green and orange.

Operating Experience Level 3 – Frequent Hazardous Electrical Energy Related Events

September 8, 2016

OE-3 ImageThis Operating Experience Level 3 (OE-3) document provides information about a safety concern related to frequent hazardous electrical energy events during work at Department of Energy (DOE) facilities. In the first 5 months of 2016, three dozen hazardous electrical energy events were reported to the Occurrence Reporting and Processing System (ORPS), with some sites indicating that additional hazardous electrical energy events were entered into site systems because they were considered “sub-ORPS.” Most of the reports (32 of 36, or 88%) indicated that no corrective actions (CAs) had been assigned.…read more
