Electrocution Video Updated: The Ray Ainsworth Story

Operating a concrete pump boom requires focus and staying alert at all times — especially when working in and around high-voltage areas. Electrocution is one of OSHA’s “Fatal Four” leading causes of workplace deaths in the construction industry.

“When you unfold your boom, be aware of where you are and what you’re doing,” says Ray Ainsworth, the subject of ACPA’s recently updated safety video, The Ray Ainsworth Story (Electrocution). The video is a case study about the high-voltage accident that nearly took his life. While lucky to be alive, Ainsworth suffered severe burns on his limbs, torso, back and head. He lost a finger and the use of his right hand.

“Electrocution remains one of the leading causes of death in concrete construction.”

ACPA’s 2022 re-release of the video preserves Ainsworth’s story while also providing updated guidance on power line safety. Measures that have changed since the video’s inception include ACPA’s extension of the 17-foot rule to a minimum clearance of 20 feet from power lines carrying up to 350,000 volts (and 50 feet for 350,000+ volts). Other updates include the requirement of a spotter when power lines are in the boom movement area of a pour and responsibilities outlined in ASME B30.27, Material Placement Systems.

Ainsworth was not a novice. He had been working in the concrete pumping industry for nearly a decade and owned a concrete pumping business in Mesa, Arizona. Prior to that, he drove a concrete ready mixed truck for nine years. But accidents happen to even the most experienced construction professionals, and this video reminds viewers to be vigilant about locating power lines and following safety procedures.

The Ray Ainsworth Story is dedicated to all concrete pump operators and construction site employees who have fallen victim to power line accidents. It is offered in hopes of preventing such injuries and fatalities in the future.
