Once a complaint is filed with ADOSH, it is first reviewed by the appropriate supervisor to determine if it is a valid complaint, the seriousness of the alleged hazard and the appropriate action to be taken. Valid complaints may be handled in one of two ways. First, the complaint may be assigned to an inspector for an actual on-site inspection. Second, the complaint may be handled by sending a letter to the employer, along with a description of the complaint items and a request that the employer respond to ADOSH, stating what action was taken to correct any hazards found. In either case, ADOSH will send a written response to the complainant regarding the action taken and the results.
