“Once More, Why Lock-Out, Tag-Out IS Vitally Important” – Part II” #LOTO

A cotton factory worker fell unconscious while standing up after his head became clamped in a machine. The incident happened in Wenzhou, China’s Zhejiang Province. After the worker became trapped emergency services were called to help free him. When firefighters arrived at the factory they found the worker had lost consciousness, but he was held upright because his head was clamped by a machine but he did survive the accident. Lack of using LOTO, Trip Sensors & Machine Guarding were deemed to be the cause of the accident.

The Future of Lockout/Tagout: Is Zero Risk an Outdated Approach?

The ANSI/ASSE Z244.1 Standard is considered the defining document for addressing the complex issues of lockout/tagout and methods for the control of hazardous energy, and the Z244 Committee is moving in a new direction.

The control of hazardous energy in the workplace continues to be a challenge for many employers. According to OSHA, failure to control hazardous energy accounts for nearly 10 percent of the serious accidents in many industries.

Workers servicing or maintaining machines or equipment can be seriously injured or killed if hazardous energy is not properly controlled. Injuries – sometimes fatal – resulting from the failure to control hazardous energy during maintenance activities can include electrocution, burns, crush injuries, cuts, lacerations, amputations or fractures. Craft workers, electricians, machine operators and laborers are among the 3 million workers who service equipment routinely and face the greatest risk of injury. Workers injured on the job from exposure to hazardous energy lose an average of 24 workdays for recuperation.

OSHA currently has a policy – adopted by many employers and organizations – that a zero risk blanket approach is necessary to prevent injuries. The ANSI/ASSE Z244.1 Committee is moving in a new direction, according to Todd Grover, global senior manager for applied safety Solutions at Master Lock, and a member of the committee. The new standard, he says, “Is not an effort to comply one-on-one with the OSHA standard.” Instead, he adds, “The committee addresses what’s really going on in the workplace. When power must be present, there are responsible ways to protect people and the standard brings greater awareness to that.”

Grover says that the OSHA standard – Control of Hazardous Energy (Lockout/Tagout) (29 CFR 1910.147) for general industry – has remained static (with multiple letters of interpretation), while the technology found in the machines being manufactured today has advanced. The traditional approach to lockout/tagout – completely shutting down machinery – might not be the best option for some of today’s equipment or for some of the operations maintenance personnel and operators need to perform.

“The companies building and selling these machines have the capability to make machines that are easy to lock out,” says Grover. “Detailed instructions, initial lockout instructions, and guidance… These are obligations created at the manufacturer level.”

The zero-risk blanket approach is outdated, he adds and is in conflict with current safety management practice.

“Lockout, in its essence, is a procedural or administration step in the hierarchy of controls. Its effectiveness is dependent on employers and workers,” he says. “An engineering control, through machine design and manufacturer-installed series of highly sophisticated interlocks that have self-monitoring and multiple energy sources that aren’t dependent on decisions made by employers and workers, is reflective of the current capacity of manufacturers.”

Grover says that the reality is that one out of 10 employers have what he says is a “credible” lockout program, one that goes beyond simple OSHA compliance. Another 60 percent do their best to meet the requirements of 29 CFR 1910.147. The final 30 percent have no lockout program whatsoever.

The latest revision of ANSI/ASSE Z244.1 is based on what Grover calls best practices in manufacturing. “We had some spirited debates about what constitutes ‘best practices,’” he admits, “but we came to a good consensus.”

According to the standard, an employer adopting a hazardous energy control program should start with conducting a thorough risk assessment and allowing that risk assessment to guide the hazardous energy control program in the workplace. It needs to be a “living” program that develops and adapts according to changes in the workplace such as new production lines, new technology, and new machinery.

Everything needs to be documented, employees need to be trained based on the risks and there needs to be validation that the hazardous energy control program is effective. Done correctly, says Grover, the hazardous energy control program could serve as a “micro safety program” that contains elements – risk assessment, communication, best practices, training and validation that the program is effective – could be used as a template for respiratory protection, fall protection, and other workplace challenges.

“It’s a scalable program,” he says. “Whether it is being adopted in its entirety by a large manufacturing company or a small company uses nuggets of it to take their hazardous energy control program to the next level.”

The program, he adds, “show[s]employees that we care for their welfare by not allowing them to work in hazardous environments, where an unexpected startup can catch them.”

Grover was the featured speaker at a Jan. 11 webinar hosted by the American Society of Safety Engineers titled “Highlights of the 2016 ANSI/ASSE Z244.1 Standard: Lockout, Tagout and Alternative Methods. While there is a fee to register for the archived webinar, registration does include access to the electronic versions of:

  • ANSI/ASSE Z244.2016 (current standard)
  • Historic version of the ANSI/ASSE Z244 Standards
  • ANSI/ASSE Z490.1-2016 Criteria for Accepted Practices in Safety, Health and Environmental Training
  • ANSI/ASSE Z590.3-2011 (R2016) Prevention through Design Guidelines for Addressing Occupational Hazards and Risks in Design and Redesign Processes
