Safety Sign Examples

Part 90 of the Michigan Occupational Safety and Health Act (MIOSHA, Act Number 154, Public Act 1974, as amended) requires general industry to prepare safe practices and procedures to protect employees from hazards of entry into certain confined spaces. Further, any firm having certain confined spaces shall provide information to the Fire Chief upon request.


To assist our department in fulfilling its responsibilities under MIOSHA, we are requesting that you complete a confined space survey. If your firm does not have any confined space(s), you still need to complete the form. This information can be beneficial to you and our firefighter/rescue personnel when responding to an emergency at your facility.

If the information you provide indicates that your firm has certain confined spaces, we will be contacting you for further information and a more detailed survey of your site. Livonia Fire and Rescue does not currently provide a confined space entry team.

Please complete the survey and forward to the Livonia Fire and Rescue Department, Attention: Senior Fire Inspector. All surveys, including negative responses, will be kept on file for future use and to satisfy MIOSHA requirements. If there is a change regarding the existence of a confined space, please contact us so that we may update our files.
