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.


Fluke Recalls T110, T130 and T150 Two-Pole Voltage Testers

Please be on the lookout for Fluke T-Pole Testers (Fluke T110, T130, and T150, pictured below). These have been recalled because they may fail to indicate that live voltage is present. If you see any of these, take them out of service immediately and turn in to the Electrical Safety Group.

As a reminder, only those meters and testers listed in Appendix E of the Electrical Safety Manual are approved for ZVV. Fluke T-Pole Testers are not on the approved list.

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

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


  1. 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.
  2. 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.
  3. 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.

Reminder on Space Heater Safety:

  • Assure that the space heater is listed by UL, TUV, ETL, or CSA (see label on bottom or side).
  • Always plug heater directly into facility receptacle, never into extension cords or relocatable power taps. Make sure the plug is not loose in the outlet.
  • Read and follow all manufacturer’s warnings on cord label and/or in manual.
  • If heater power cord or wall receptacle feels hot to the touch, discontinue use.
  • Unplug heater when no in use.
  • Avoid leaving heater running when unattended, in offices.
  • Place heater out of traffic and on a level, flat surface (carpet is ok).
  • Avoid placing heaters on furniture or countertops.
  • Keep front of heater 3 feet away from combustibles.
  • Do not operate damaged heater, if dropped, or with a damaged cord.
  • Do not run heater cord under carpet. Place cord out of foot traffic.
  • Do not use two heaters on the same circuit (e.g., in the same office area).
  • If a breaker trips in your area, contact your facility contact person.
  • NOTE: there is no need to test tiltover action. If it is listed and not recalled, it is ok. The fan may stay on, when turned face down, that is proper on certain settings.
