Doing the wrong thing during an agency inspection can have bad consequences. Always be prepared for any agency inspection. That means you need to have all your environmental records in good condition at all times. Make sure they are up to date and easily accessible to the inspector. The last thing you want to have happened is to have the inspector wait around at your facility while you scurry around looking for records that the inspector wants to review.
Another thing to remember is NEVER reprimand your own employees in front of any inspector. Why? It gives the inspector a very negative perception of how you run your business and treat your employees. Furthermore, you have just humiliated your employee in front the inspector and you have just made an enemy out of that employee.
