In general, synthetic chemicals prior to marketing will undergo testing (hazard identification) and the results of this will be used in the risk assessment (second level), after which there is risk management (as the third level, to determine whether any restrictions are needed for use).

The Safety Verification Tasks assure that the hazard control is validated to be appropriate and verified to be in place. Verification of the implementation of system safety processes into company operations is very important, not only for regulatory audit and inspection survival but also to be sure that money is spent wisely. Verification is done through review and approval of the design process, input to specifications that call for verification schemes, and various tests (i.e., acquisition, operational, safety) to physically test hazard control adequacy. Of course, physical inspections (destructive and nondestructive) are part of the verification process. This is extremely important in product safety, but also very important in any plant safety. Explaining the testing of safety-critical systems and testing systems to assure they operate safely is very important. 

I was involved in gronnd testing of the redesign of the solid rocket booster after the Challenger accident. Our test safety program used a combination of safety tools with the hazard analysis as the central tool to identify test hazards and track controls to closnre. 

System safety is generally involved in the acceptance test process. Safety may review test results to ensure safety concerns are adequately resolved and that design safety requirements are met. Safety may also review acceptance test procedures to ensure that no test hazards exist and that the potential mishap risk of a test is acceptable. It may be necessary for safety to be present as a witness to the conduct of certain acceptance tests, generally on safety-critical components.
