What Information Must the Employee Provide? Employees or their representatives must provide enough information for OSHA to determine that a hazard probably exists. Workers do not have to know whether a specific OSHA standard has been violated in order to file a complaint. The following are examples of the type of information that would be useful to OSHA when receiving a complaint. It is not necessary to have the answers to all these questions in order to file a complaint. The list is provided here as a guide to help you provide as much complete and accurate information as possible: (1) How many employees work at the site and how many are exposed to the hazard? (2) How and when are workers exposed? (3) What work is performed in the unsafe or unhealthful area? (4) What type of equipment is used? Is it in good condition? (5) What materials and/or chemicals are used? (6) Have employees been informed or trained regarding hazardous conditions? (7) What process and/or operation is involved? (8) What kinds of work are done nearby? (9) How often and for how long do employees work at the task that leads to their exposure? (10) How long (to your knowledge) has the condition existed? (11) Have any attempts been made to correct the problem? (12) On what shifts does the hazard exist? (13) Has anyone been injured or made ill as a result of this problem? (14) Have there been any "near-miss" incidents? See more from topic source: https://www.osha.gov/html/a-z-index.html
