Safety Audit covers all aspects of safety of the underta+in includin compliance with
statutory rules$ oranisation and administration$ eneral hazard control$ process hazard
control$ trainin and motivation$ accident investiation and cause analysis etc.
A Safety Audit examines and assesses in details the standards of all facts of a particular
activity. ,t extends from complex technical operations and emerency procedures to
clearance certificate$ job descriptions$ house+eepin and attitudes. ,t also involves labour
relations since people are as+ed about their trainin$ their understandin of wor+s policy
and whether they thin+ they are ma+in their contribution in the riht way.
The safety audit has been carried out as per the uidelines iven in the -,ndian Standard
Code of #ractice on )ccupational Safety and ealth Audit /0,S123345125546.
The Audit findins and recommendations are based on the bac+round information %
process data and discussions held with the plant personnel durin onsite audit activities.
2.0 OBJECTIVES
The purpose of conductin Safety Audit is that a systematic critical appraisal of all
potential hazards involved$ plant personnel$ plant$ services and operation methods to
ensure that occupational health and safety standards fully satisfy the leal requirements
and those of the company’s written safety policies$ objectives and prorammes.
