If you believe working conditions are unsafe or unhealthful, we recommend that you bring the conditions to your employer's attention, if possible.
You may file a complaint with OSHA concerning a hazardous working condition at any time. However, you should not leave the worksite merely because you have filed a complaint. If the condition clearly presents a risk of death or serious physical harm, there is not sufficient time for OSHA to inspect, and, where possible, you have brought the condition to the attention of your employer, you may have a legal right to refuse to work in a situation in which you would be exposed to the hazard. (OSHA cannot enforce union contracts that give employees the right to refuse to work.)
Your right to refuse to do a task is protected if all of the following conditions are met:
You should take the following steps:
If your employer retaliates against you for refusing to perform the dangerous work, contact OSHA immediately. Complaints of retaliation must be made to OSHA within 30 days of the alleged reprisal. To contact OSHA call 1-800-321-OSHA (6742) and ask to be connected to your closest area office. No form is required to file a discrimination complaint, but you must call OSHA.
