Worker’s safety and well-being is the fundamental requirement in each and every workplace in the industrial and construction sites. Taking this into consideration, we tried utmost to cover this important aspect and focused to fill this narrow gap that often goes neglected. This research aims to fabricate a safety helmet along with provision of a sustainable cooling atmosphere, which would fit the economic feasibility and would be within industry approved design standards. To verify the safety of the helmet, we simulated our helmet in set conditions. As for the cooling, a phase change material (PCM) was selected due to its high efficiency to store high thermal energy, phase changing properties and recharging abilities. The temperature distribution and time required for the PCM to completely change its state i.e from solid state to liquid state was simulated through CFD Analysis. During our experimentation analysis, we used Paraffin wax as our phase change material (PCM) which was encapsulated in aluminium foil packets which were sealed to ensure that heat conduction to the PCM was facilitated easily and without leakage. In this way, our structural and thermal design analysis of the safety helmet was successfully finalized.
