Power Tool Safety System
WiSys: T250029US01
Inventors: Corey Hedlund, Samuel Koland, Audra Glosemeyer, Scarlett Kirkpatrick
WiSys is currently seeking a strategic partner in the power tool or PPE industry that is interested in co-development opportunities and would ultimately provide a route to market for commercialization of this novel safety system.
Overview
According to the U.S. Bureau of Labor Statistics, the construction industry recorded 173 non-fatal injuries and 1,075 fatal injuries in 2023 – the highest number of fatalities across all industry sectors that year. Additionally, Eye and Face protection violations ranked among the top 10 most frequently cited standards by Federal OSHA inspectors in the construction sector during fiscal year 2024. Studies show that construction workers who do not use personal protective equipment (PPE) are three times more likely to be injured, yet PPE non-compliance remains a significant issue. One study found that only 60% of surveyed workers consistently wore their PPE on the job. Common barriers include discomfort, poor fit, a lack of knowledge about proper usage, and insufficient enforcement by supervisors. Supervisors often struggle to enforce PPE rules due to competing responsibilities and limited capacity to monitor compliance effectively.
The Invention
To address this critical safety gap, a team of students at the University of Wisconsin–Stout developed an innovative PPE enforcement system that would reduce the burden on supervisors while enhancing worker safety. The device links PPE to the power source of construction tools assuring that if the required PPE is not worn correctly, the tool will not operate. For example, if a worker’s safety glasses and helmet are not properly in place, the connected saw will remain inactive. This solution was initially prototyped and tested during a university event sponsored by a local construction company, and further refinement and testing is ongoing. As smart PPE gains traction, driven by technological advancement and tightening safety regulations, the demand for such innovative solutions continues to grow.
Applications
- Ensures workers wear PPE before operating tools
- Can be used with battery- or wall-powered tools
Key Benefits
- Customizable for worksite-required PPE items
- Helps companies meet OSHA and industry-specific safety standards
- Prevents workplace injury
- Reduces supervisor workload by automating compliance checks
- Adaptable to pre-existing power sources in tools
Stage of Development
This solution was initially prototyped and tested during a university event sponsored by a local construction company, and further refinement and testing is ongoing.
