stress contributed to 18 % of the 629 reported personal injuries. In fact, heat-related injuries accounted for 17 % to 25 % of total reported injuries across all crane-related roles, including riggers and signalpersons. This is not surprising given the amount of time crane operators spend in the cab throughout the day, and the exhausting work done by ground crews in direct sunlight before, during and after a lift.
The impact of heat stress can therefore be significant to both the individual and those working with them. Heat stress can cause heat cramps, heat edema, heat exhaustion, heat rash, heat syncope and even heat stroke. In addition, these conditions and their effects can have adverse effects on the work being performed on the jobsite. For example, whether sitting in the cab or working on the ground, people experiencing heat stress may have impaired cognitive functions, dizziness, reduced grip strength or impaired coordination, all of which could lead to safety concerns when dealing with precise movements and often heavy loads on a jobsite full of workers.
The obvious question is what can be done to try to mitigate heat stress, given the potential for it to occur and significant safety concerns when it does. Several resources about heat stress and how to address it exist, including a tool designed to assist in strategically minimizing heat stress and other common safety hazards present in the crane industry. The Crane Operations Jobsite Safety Controls Tool, developed by the NCCCOF and NSC, provides a framework that prioritizes hazard mitigation strategies through the Hierarchy of Controls. The tool provides various heat stress mitigation strategies, including elimination( e. g., autonomous cranes), substitution( e. g., upgrading older equipment), engineering controls( e. g., cooling / hydration stations), administrative controls( e. g., structured work / rest cycles) and personal protective equipment( e. g., cooling vests).
