Safety is defined as ensuring the limitation of events or elements that are potentially harmful and can cause accidents that can cause loss or damage to life and property. Safety is crucial to all industrial sectors and is a core value for hazardous industries.The significant part is adherence to standard practices and precautions at workplaces that limit hazards and accidents which are detrimental to humans and environment. As per OSHA, there are safety standards that suggest the industries the methods to implement for protecting their employees from hazards. These standards ensure that the employees work in safe environment and are provided training and assistance to carry out a particular task. Worldwide there are strict local, regional and national regulations that govern the safety standards with the aim to minimize the loss or damage to life and property.
Process hazard analysis (PHA), comprises of specialized studies such as HAZID, HAZOP, ENVID, PHSER, Working Environmental Analysis, SIMOPS/MOPO/BOWTIE and OHID/OHRA/HRA/HCA. PHA is necessary to study the processes in detailed manner to identify the risk factors and compensate the risk by suggesting the mitigating measures. The studies such as Quantitative risk assessment are utilized by various industries to provide a quantitative measure to the risk factor to understand the severity for on time action. QRA study includes Gas and Smoke Dispersion Study, FERA, Flare Radiation and Dispersion, EESA, EERA, ALARP.
The studies that are conducted to minimize the loss of the facility when a hazard occurs are included under Loss Prevention Activities which includes HAC, F&G detection layout, Fire water estimation, Passive fire protection analysis, Fire and safety equipment Layout and Escape route Layout. Reliability studies aim at increasing the safety of the processes and operation of the industry. It helps to minimize the equipment and process related damages and ensure operation and process safety. Reliability studies include RAM study, SIL Classification and verification and FMEA. Safety studies optimize measures for better utilization of resources and protect from loss or damage to life and property. TEPL aims to minimize the hazards in the industries through expertise based safety studies and contribute to make workplaces safer and better.
