An incident on a scissor lift earlier this month at a Frito-Lay North America facility in Irving, Texas, left a worker dead and two others badly injured.
The nature of what was being done is unclear. The employer is Walker Industrial, a specialty contractor that provides automation and other industrial services.
Initially the incident was described as a collision between two ladders on Oct. 4, said a spokesman for the Irving Police Dept. He added the workers fell about 30 feet. One of the injured was in critical condition.
In a statement, Walker Industrial said it is investigating the accident and its “deepest sympathies are offered to the families of everyone impacted by this incident.”
A spokesman for the regional Occupational Safety and Health Administration’s office said an investigation is underway.
The stability of fully extended scissor lifts has long been a concern. Safety regulators have pointed to hazards in uneven ground, overloading and accidental contact with controls. In an accident on a high-rise building construction project in Oklahoma City in 2016, a scissor lift operator tumbled to his death by falling from the building.
There are numerous sources of information about how to work safely with scissor lifts.
Among them are the Statement of Best Practices for Workplace Risk Assessment and Aerial Work Platform Equipment Selection, published by several different organizations including the Association of Equipment Manufactures (AEM). In addition, every aerial lift rental comes with an owners/operators manual, an ANSI Manual of Responsibilities, and an AEM Safety Manual. Each facility typically has its own list of site-specific aerial lift rules, too.
