5 Steps to… Turning Workplaces Into Safe Places
1. Safety Audit / Risk Assessment 2. PSR (Pre –Start Safety
Review) 3. Design And Installation 4. PSR Sign-Off … 5. Training and Documentation
Step 2--PSR review Report •A pre-start review is a written report that details measures taken to ensure that the construction, addition, modification and or installation of a new apparatus, protective element or process is compliant with current standards before production begins. •Pre-Start Health & Safety Review is a report written by a PROFESSIONAL ENGINEER** that details the measures necessary for compliance with applicable sections. •This is done at the design stage and the report will outline the steps needed for compliance. These steps or measures are to be completed by the employer before any production operation begins.
