Is Risk assessment and Control measures effective when no accident or incidents happen? Prove it. Also can we eliminate hazard in a work environment?

first , hazards at a workplace can not be eliminated but can be reduced to manageble threshholds.

risk assessment/control measures alone can not trasnlate to an accident/incident free workplace. if a workplace records no accident/incident then it means there is a positive culture of safety inplace. a good workplace safety culture means that hse management system if positively implimented and  understood. That involves risk assessment,trainings,hse meetings,tool box talks,compliance with statutory requirements,ppe use etc. That will ensure zero harm at work.

Hazard identification (HAZID) and risk assessment involves a critical sequence of information gathering and the application of a decision-making process.  These assist in discovering what could possibly cause a major accident (hazard identification), how likely it is that a major accident would occur and the potential consequences (risk assessment) and what options there are for preventing and mitigating a major accident (control measures). These activities should also assist in improving operations and productivity and reduce the occurrence of incidents and near misses.

There are many different techniques for carrying out hazard identification and risk assessment at an MHF. The techniques vary in complexity and should match the circumstances of the MHF.  Collaboration between management and staff is fundamental to achieving effective and efficient hazard identification and risk assessment processes.
