Case Studies

Samsung: Clean Room Heat Injury Monitoring

Samsung USA performed an evaluation protocol of the Sempulse Halo system and continued its use for 6 months afterwards. Samsung operated a clean room which required protective gear in a room over 115°F. The protective gear had a battery-powered cooling unit, but company policy limited all workers to 20-minute shifts in the clean room. Getting into the gear took employees 5-7 minutes. Getting out of the gear took 3-5 minutes and after exiting the clean room and the gear, each employee spent 15 minutes in a chilled room to lower their body temperatures. This was then followed by a 10 to 15-minute break.  Each cycle was 1 hour in length with only 20 minutes of productive work. 20 minutes was selected because historically over the previous 12 years this was experimentally found to be the working time which was successful for 100% of employees.

Samsung wanted to change this paradigm and evaluate each worker individually with Sempulse Halo devices. Each clean room employee was fitted with Sempulse Halo devices and LiveCharts was installed on their personal Android Samsung smart devices. Halo devices were applied at the beginning of each employee’s work shift. The initial evaluation centered around heat injury, mobility, ease of use, and any potential conflicts with their existing equipment. No issues were found. Non-invasive blood pressure (NIBP), SpO₂, pulse rate, respiratory rate, ECG, HRV, VO₂ Max, core body temperature, and skin temperature were new in-motion measurements for their organization.

Over the course of the trial, Samsung was able to raise the average working shift from 20 to 38 minutes, a 90% improvement. Some employees were able to sustain working conditions for upwards of 47 minutes, a 135% improvement. Certain individuals were able to withstand the conditions better than others. Samsung used biographical information to map out those traits that lent themselves to better heat acclimation. Samsung was able to add performance bonuses to those able to work longer than the original 20 minutes. Production metrics over the evaluation period resulted in a 110% improvement in efficiency, effectively more than doubling the capacity of their workforce.
