In a breakthrough that bridges engineering and safety science, Nigerian-born doctoral researcher Solomon Ajasa of the University of Alabama has unveiled a hybrid technology system designed to detect and prevent accidents at construction sites, with a focus on fall hazards.
Ajasa’s innovation responds to the high rate of workplace injuries in Nigeria’s construction sector, where insufficient safety infrastructure has left many workers vulnerable. By integrating multiple technologies to monitor risk in real time and issue early warnings, the system aims to revolutionize occupational safety practices, not just in Nigeria but across similar high-risk industries globally.
The researcher emphasized that his work underscores the importance of data-driven safety mechanisms in sectors like construction and mining—where the cost of inaction is often measured in lives.
He said the project had led to the development of heat stress training materials under an initiative funded by the U.S. Department of Labour’s Occupational Safety and Health Administration (OSHA).
Ajasa emphasised that the innovation was paving the way for improved workplace safety and had the potential to impact industries beyond construction.
“The technology-driven approach aims to protect workers across industries from emerging threats such as extreme weather, infectious diseases, and evolving construction risks.
“Through data-driven research and hands-on training, we have impacted workplace safety in the United States and beyond, “Ajasa said
The doctoral student said the system had been used to train over 400 surface miners and 800 construction workers, equipping them with crucial knowledge to recognise early heat exposure symptoms and take preventive measures.
Citing instances, he said that his passion for research and training in occupational safety stemmed from when he witnessed two tragic construction accidents in Nigeria as a field officer.
He noted that through the programme, in addition to construction safety, he had played a significant role in mine safety training.
This initiative, he said, was developed in response to data showing that new and inexperienced surface miners accounted for approximately 26% of total mining accidents.
