Klein NCVT-1 Voluntary Safety Recall

June 11, 2021

Klein has issued a recall on some of their NCVT-1 non-contact voltage testers where an operator error (keeping the on/off button depressed) would erroneously indicate that the tool is ready to detect voltage by providing a green light at the tip of the tool when it in fact is not ready.

Klein Tools NCVT-1 Non-Contact Voltage Tester, 50-1000 Volts

Most of the non-contact voltage detectors (proximity detectors)  that are being used at the laboratory are made by Fluke.  Proximity detectors of this type are widely available and many people use them at home. Klein is a well known manufacturer of electrical tools for industry.
Those in possession of Klein NCVT should verify the model of the detector; if the detector is an NCVT-1 then look at the corresponding date codes and follow the manufacturer instructions available here.
If the Laboratory has provided you with one of the detectors included in this recall, please let your DSC and ESC representative know so that we can keep track at the Laboratory of potential impact/extent of conditions.

 

Electrical Safety Support During Curtailed Operations

While the Laboratory is in a state of Curtailed Operations, the Electrical Safety Group will reduce it’s on site presence to practice “Social Distancing”.  Support of the Laboratory’s mission will continue to take place remotely.  Requests that require on-site support will be prioritized and coordinated to ensure best use of limited resources. Response time may be delayed.

Schneider Recalls General Duty Safety Switches

Safety Alert

Schneider Electric Recalls Square D Brand General Duty Safety Switches

Schneider electric has recalled their Square D Brand General Duty 30 & 60A, 120/240 Volt 2-phase and 3-phase NEMA 3R Safety Switches. The power can stay on even when the switch is in the “OFF” position. This poses a serious shock or electrocution hazard. The recalled switches were manufactured from January 1, 2014 through January 18, 2018. See photo below for an example switch affected by the Safety Alert. …Read more

Operating Experience Level 3 – Frequent Hazardous Electrical Energy Related Events

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.

The potential danger of contact with electricity cannot be overstated. If CAs are not assigned every time a seemingly insignificant electrical event occurs, there is the real possibility that the next event may be fatal.

Duke Energy: 1 employee electrocuted and company fined for failing to implement control measures its safety team developed to protect employees

DUKE Energy fined $90,000 in connection with worker death.

Dasher and other employees were testing equipment at a substation when Dasher came into contact with a test line carrying approximately 10,000 volts of electricity.

Officials said Dasher fell down. When co-workers got to him, he was breathing. They immediately contacted medical personnel and performed CPR while waiting for an ambulance to arrive.

Dasher was rushed to the hospital in critical condition. The 35-year-old Oxford man died eight days later at the hospital.

A news release issued by the U.S. Department of Labor states that Dasher was using a circuit-testing technique that bypassed safety protocols designed to protect workers from electrical currents. Duke Energy, the release states, knew workers were bypassing safety protocols to conduct testing and did not enforce safety standards. Because of this, officials said “the company has a history of nonfatal shock injuries.”

“Duke Energy is aware of the fatal hazards that Dasher and other workers are exposed to but failed to implement control measures its safety team developed to protect employees,” said Brian Sturtecky, director of OSHA’s Jacksonville area office, on Friday.
The release explains that a willful citation was given to Duke Energy for “failure to have a qualified observer present during testing that could immediately de-energize circuits,” and that “a willful violation is one committed with intentional, knowing or voluntary disregard for the law’s requirement, or with plain indifference to worker safety and health.”

Serious citations OSHA officials gave Duke Energy were for failure to ensure transformers were grounded and safety-checked between each test, and failure to provide training to workers who assisted with transformer testing. Another citation came from failure to ensure controlled access to the test area to protect workers from electrical shock hazards.

A serious violation is described as when there is substantial probability that death or serious physical harm could result from a hazard, about which the employer knew or should have known.

OSHA officials have proposed that Duke Energy be placed on their “severe violator enforcement program for demonstrating indifference to its OSHA obligations to provide a safe and healthful workplace for employees.”

Safety Alert 2015-002: LOTO Hasp Breaks When Challenging Lock During LOTO

IMG_2888Facility Electricians had de-energized and performed zero energy verification for a piece of equipment as part of a Lockout/Tagout procedure. A multi-lock hasp was applied to the energy isolation as part of the LOTO.

An Engineering Technician planning to work on the LOTO’d equipment placed his lock and tag on the hasp, along with the other locks already applied. The technician noticed that the hasp was cocked at an odd angle. He then challenged the lock by tugging on it several times to ensure it was latched, per his LOTO training. The metal of the hasp snapped.

An immediate stop work was called, and Facilities electricians were called to re-establish and re-verify the LOTO before work continued. Read the full Alert for more information and recommendations:

Draft 2 of Chapter 8 and the Electrical Safety Manual Out for Review

The second draft of the proposed revisions to the Lab’s  electrical safety program (PUB-3000, Chapter 8 and the Electrical Safety Manual) have been completed. Both documents are available for viewing. The initial drafts received close to 500 comments from across the lab. These comments were processed and voted on for resolution by an Electrical Safety Sub-Committee and have been incorporated into the current drafts. The next step will be a joint Safety Advisory Committee (SAC) and Electrical Safety Committee (ESC) effort in February to test the proposed electrical work categorization against the actual electrical work being performed in the labs.

This has been a huge effort and is a big change from how we have conducted business in the past. By focusing on the electrical hazards that we may be exposed to or expose others to in the course of our work, their removal and/or mitigation, and the associated electrical safe work practices, we are confident that we can create a vibrant electrical safety culture that furthers our scientific mission.
