The Technical Organization improved its Incidence Rate by 8.8% while Asia-Pacific and China improved their respective Incidence Rates by 39% and 32%. In other key developments:  Supervisor specific safety training was developed to help cultivate an ideal safety culture where supervisors understand their role in creating an environment in which employees feel safe to speak up and express their ideas and concerns.

Health and Safety also worked with the Global Manufacturing function to introduce collaborative robots to address certain ergonomic risks. MEETING A CHALLENGING ENVIRONMENT For example, after achieving in 2020 a record low Incidence Rate, the rate of recordable injuries, Cummins saw an increase in 2021 from 0.48 to 0.57. The 2021 rate was below the company’s 0.59 Incidence Rate in 2019, which at that time was the lowest Incidence Rate at the company since 2015. Cummins’ Severity Case Rate, the rate of lost or restricted workdays, increased to 0.28 in 2021 from 0.21 in 2020. In 2019, the rate was 0.23, a 15% improvement over 2018’s rate of 0.26. The company’s Ergonomics Incidence Rate, the rate of ergonomic injuries, increased to 0.17 in 2021, up from 0.12 in 2020. Cummins’ Health and Safety leaders note that the fourth quarter contributed the fewest recordable injuries in 2021, an indication that mitigation efforts, including working with sites to maintain a focus on safety amid the many challenges they faced, were working. The company ended the year with no employee fatalities. from across the company’s functions and regions to promote the initiative’s importance. A Potential Serious Injury and Fatality is defined as a work-related incident that had the potential to lead to a serious injury or fatality if not for one or two factors. A serious injury is considered a life threatening injury or illness requiring medical intervention to prevent death, while a life altering injury or illness is something that results in a permanent loss of a body part or function. Health and Safety leaders at Cummins believe the PSIF initiative enables plants and facilities to more easily and effectively identify, report and evaluate all safety incidents to determine their potential to become a serious injury or fatality and address the most serious risks. Employees are strongly encouraged to report all incidents and potential incidents. Underscoring the importance of this new initiative was an uptick in several key safety metrics at Cummins in 2021 as the company confronted a rapid escalation in business following shut-downs in the immediate aftermath of the COVID-19 pandemic a year earlier.
