TheYerkes-DodsonModelwasdevelopedbytwoto correlate stress and psychologists in 1908 to correlate stress and performance. They found that while a certain amount of positive stress can enhance performance, outside that positive zoneinperformance. They found that either directionperformance starts to be eroded. On one hand you have people doing boring, monotonouswhile a certain amount of tasks that dont have enough of that positive stress, and they can become complacent and have a lapse in situationalpositive stress can enhance awareness, Kiehl says. On the other end of the bell curve are individuals who are on the edge of burnouttheyre doing too much, the stress is too high, and they developperformance, outside that tunnel vision, which is a real physiological phenomenon.Harvard Medical School found that insomnia costs thepositive zonein either average worker in the U.S. 11 days of productivity a yearfor a yearly total of $63 billion.

More work needs to be done to build a direct link between actualworkplaceaccidentsandtherolethatdeficient situational awareness plays in causing them. Everybody agrees that theres a problem, but theres a lack of ability to acquire the data to quantify how largeWith the corporate culture side in mind, Cowart has developed it is and then fix it, Kiehl says. As of now, a lot of thea list of five questions he poses to clients and audiences at trade organizations youre seeing are the early adopterstheyreevents:acting more from initial hypotheses than hard numbers. Technology solutions, especially sensor-based technologies,1.Do you or your organization have a process to manage your can really help provide the data to quantify if employersJourney to Zero (incidents)?can also handle the safety culture issues. 2.How are cultural stigmas frustrating your Journey to Zero?3.Are employees getting sufficient quality and quantity of sleep?4.Do employees have sufficient opportunities to get sleep?5.What controls do you have in place to protect those workers who are most exposed to risk?While Caterpillar, Sentinel and Scan-Link all provide technology solutionsthathelptoreducetheriskoflapsesinworkplace situational awareness, its notable that technology is part of the TEC answer to only one questionNumber 5. is, says Fava. TEC Having the technology is good, but you need to know what the GPSroot cause of lapses in SA (situational awareness) You need that data. Were moving in that direction with a lot of AERIAL our clients because its not just about knowing youve had so many near misses. Now we want to know why we had those near misses. You can make positive changesif you have the data. 14 AVENUESFALL 2021'
