The present disclosure discloses a wearable device to indicate a hazardous condition. The said device comprises one or more thermochromic paint coating layers, each indicative of a colour based on variations in temperature, one or more thermoelectric couples to regulate the temperature of corresponding one or more thermochromic paint coating layers, and a control module. The control module is configured to receive one or more parameters from one or more sensors associated with the one or more thermoelectric couples, determine one of presence and absence of at least one hazardous condition by comparing the one or more parameters with corresponding threshold parameters and configure the one or more thermoelectric couples to regulate temperature of the corresponding one or more thermochromic paint coating layers and to dynamically control indication of the colour, based on one of the presence and absence of the at least one hazardous condition.
