Safety Audit is a very elaborate audit of the premises where all the aspects of safety are audited threadbare. In this audit, complete OR selected premises, as per the mandate, are inspected. Safety related documents are also reviewed. Extensive discussions with the related personnel are held on various audit issues. All the processes, warehouses, utilities and related areas are audited. If the scope permits issues like Consequential Analysis, Dispersion Modeling, Emergency Relief System Review, Maximum credible loss scenario estimation etc. Are also included in the audit.

In an OSH audit, exhaustive evaluation of safety and health hazards is undertaken. Sources of these hazards are identified and recommendation made to reduce the occurrence of hazards. Suggestions are also provided to mitigate adverse consequences of hazards. The OHSA study includes review of the safety system documentation. Reporting systems are also reviewed as part of the study. If there is a requirement to study the processes as well, the safety audits and OSHA study can be extended to a full fledged process safety audit.
