Chemical reactivity hazards present complex challenges in industrial settings, encompassing various types of reactions and chemical substances. This presentation delves into the diverse array of reactivity hazards, including the risks associated with monomers, oxidizers, runaway reactions, autoignition phenomena, organic peroxides, highly energetic materials, and pyrophoric chemicals. Through an exploration of the characteristics and behaviors of these substances, attendees will gain insights into the mechanisms driving hazardous reactions and the potential consequences of uncontrolled reactivity. By fostering a deeper understanding of chemical reactivity hazards and equipping attendees with identification approaches, this presentation aims to enhance safety awareness and promote a culture of prevention.
