Wearable for Jaali (Brick firing workers)

The workers in the brick industry are subjected to extreme working conditions and poor remuneration. Currently in India, brick manufacturing is a labour intensive sector, with crude techniques causing considerable work drudgery. They are also exposed to high concentrations of Respirable Suspended Particulate Matter( RSPM), during monitoring and regulating the fire, as the furnace chamber is covered with ash( ash acts as insulator). The nature of the work requires skilled labour especially for moulding and firing. The project addresses the issues faced by Jalaai workers during the brick firing process and  a system is designed in order to sustain them while working under high radiant heat temperature.

Taking the concept of evaporative cooling, to enable body temperature drop by sweat evaporation, helmet is designed. This enables faster rate of evaporation of sweat from the surface of the head. The process of pouring water over the porous material at regular intervals of time and its level of easiness for the evaporative cooling technology.

a) The retractable visor enables the worker to talk to their fellow workers without taking their helmet off and spit both of which are very essential to their natural way of work. b) The ventilation also prevents the visor from becoming foggy. c) The product does not require any maintenance d) The cleaning wiper is slid through the channel in the middle so that the visor cannot be dusty as the environment is dusty. e) Heat reflective aluminized polyester film which is capable of reflecting 97 % of radiant heat. f) Visor is extended at the top part of the head so as to protect from immediate radiant heat
