Hazard Analysis and Design in Chemical Engineering

Hazard is the intrinsic property of a material or process which harms the people, buildings, or environment. Health, safety, hazard, risk assessment, loss prevention, and environmental consideration play an important role while designing a chemical processing plant. Hazard is often confused with risk. Risk measures the magnitude of loss and injury of likelihood incidents or the consequence and frequency of incidents.
