Historical Perspective on Fire Safety:

The history of India has witnessed several catastrophic fire events that played a significant role in shaping the evolution of fire safety measures. Ancient Indian cities constantly faced the threat of destructive blazes due to the widespread use of inflammable construction materials like thatched roofs, wooden buildings, and open flames for lighting purposes. The Great Bombay Dock Explosion in 1944 and the Calcutta Fire of 1913 were pivotal moments that catalyzed the early efforts towards formulating fire safety regulations. The Bombay Fire Brigade Act enacted in 1945 was a pioneering first step, leading to the establishment of the country’s first organized fire service. Over time, major fire outbreaks in urban areas, like the Ahmedabad Cloth Mill Fire in 1987, highlighted the critical need for robust fire safety standards. These historical fire incidents, along with the Bhopal Gas Tragedy in 1984, led to a reassessment of industrial safety protocols, influencing building codes and emergency response systems. The historical trajectory of fire safety practices in India reflects a continual struggle to evolve and adapt, making advancements in fire resistant construction materials an urgent necessity for safeguarding structures in the present and future.
