Between 2015 and 2018, WorCover Queensland undertook a campaign to enhance knife sharpness in the red meat processing industry, aiming to reduce serious injuries associated with musculoskeletal disorders (MSDs) and cuts/lacerations resulting from knife work. This industry displays one of the highest rates of such injuries, with approximately one in two workers affected, leading to substantial claim costs averaging around $68,550.

The Challenge:

Inadequately maintained or dull knives contribute significantly to knife-related MSD injuries. The repetitive force required with dull knives can lead to various MSDs, including overuse injuries in the upper limb, elbow, shoulder, and muscular sprains and strains in areas such as the neck and lower back. Dull knives also pose a laceration risk, as workers may lose their grip.

Benefits of Sharp Knives:

A sharp knife reduces the force needed for cutting by 30%, resulting in smoother and more productive work, higher quality outcomes, and decreased discomfort and fatigue for workers.

Campaign Participants: 

Ten abattoirs in Queensland, representing around half of the red meat processing workplaces, participated. The knife sharpness analyzer objectively measured sharpness, revealing that over half the workers could be working two to three times harder than necessary, putting them at risk of musculoskeletal or laceration injuries.

Key Elements of a Good Knife Sharpening Program: Management/Safety Systems:

Provide suitable knife sharpening equipment, knives, steels, and appropriate PPE. Ensure access to suitable and well-maintained sharpening equipment. Review and update policies and procedures related to knife sharpening. Provide specific training on knife handling, safe practices, and sharpening procedures during induction. Supervisors:

Regularly inspect workers' knives and promote sharpness maintenance throughout shifts. Ensure proper PPE usage on non-knife hand/arm. Identify signs of working with a blunt knife and encourage corrective action. Promote adequate time for knife sharpening during work hours. Other Safety Considerations for Knife Holders:

Encourage the use of adjustable platforms, cutting boards, and hand tools for good working postures. Facilitate tolerance-building for new starters through a buddy system. Encourage early reporting of signs and symptoms related to upper limb issues. Ensure knives are properly stored when not in use.
