Littelfuse Survey Reveals Electrical Shock Prevention Needs a Jolt of Change


October 13, 2021

Littelfuse, Inc.,, an industrial technology manufacturing company empowering a sustainable, connected and safer world, reported its annual electrical safety survey exposed that almost all respondents had witnessed someone working on or near energized equipment of more than 50 volts. Over 50 volts puts people at risk for electrical shock and electrocution.

The survey, of over 400 people whose job is either involved in safety or work directly with electricity, tried to understand the rationale behind why electrical workers often take unsafe actions. It also uncovered the challenges safety professionals and consultants experience when trying to keep these workers safe.

“There are too many worker injuries and fatalities each year due to electrical shock, and we must do a better job preventing these incidents,” said Peter Kim, vice president and general manager, Littelfuse Industrial Business Unit. “Developing an awareness of how and why these incidents occur is the first step and then advocating for Safety by Design—using engineering controls such as Ground Fault Circuit Interrupters (GFCIs)—is the best way to keep workers safe.”

A full report is available that discusses the Littelfuse survey findings such as:

  •    –   93 percent stated that they witnessed someone working on or near energized equipment of more than 50 volts and 1/3 stated the equipment was not considered “critical”
  •    –   78 percent stated that they personally have experienced an electric shock while on the job
  •    –   36 percent stated they do not always wear the recommended level of personal protective equipment (PPE) while working on or near energized equipment of more than 50 volts
  •    –   40 percent of safety professionals and consultants said they faced budget constraint obstacles when trying to gain approval for an electrical safety improvement project at their company

This report also provides an in-depth discussion of:

  •    –   The mindset of electrical workers and safety professionals
  •    –   Why companies must take a more direct approach to electrical shock mitigation
  •    –   Why electrical shock incidents are more serious than the data reflects
  •    –   The let-go threshold and the line between injury and death
  •    –   How Prevention Through Design is better than human-based safety methods

Access Management for Your Plant and Machinery

With PILZ’s “Identification and Access Management” portfolio, they offer you a comprehensive range of products, solutions and software for the implementation of safety as well as security tasks. Below you’ll discover more about potential applications, from simple authentication to complex access permissions, and access management through to safe operating mode selection, maintenance safeguarding and safeguarding of data and networks. Experience safety and security in one system!

This solution ensures that a machine cannot resume operation while people are still in the danger zone. The maintenance safeguarding system “key-in-pocket” is designed for machines with danger zones, which are protected by a safety fence and which staff need to access – robot cells for example. In comparison with conventional lockout-tagout (LOTO) systems, maintenance safeguarding with the key-in-pocket solution is implemented via RFID keys with corresponding permissions and a safe list in the PILZ controllers. As a result, it provides a purely electronic restart protection and makes both mechanical interlocking devices and warning tags redundant.
