Michigan has adopted many federal OSHA standards and incorporates them by reference. The Michigan Occupational Safety and Health Administration (MIOSHA) lists additional requirements for construction work zones in Construction Safety and Health Standard Part 22, Signals, Signs, Tags and Barricades. Michigan also has its own version of the MUTCD, the Michigan Manual of Uniform Traffic Control Devices, 2011 (link below).
The Michigan rules in Part 22 relate to “the design, placement, relocation, covering, removal, use, and maintenance of signals, traffic control devices, accident prevention signs, tags, and barricades for construction operations.” (R 408.42201). Terms are defined such as:
- Barricade - a readily visible obstruction used to direct the passage of employees or vehicles.
- Barrier - a device that is designed to prevent penetration from a way of travel to areas behind the barrier to minimize injury to employees who perform construction operations.
- Traffic control device - all signs, signals, markings, and devices placed or erected for the purpose of regulating, warning, and guiding vehicular traffic and for providing employee protection in a work zone.
- Work zone - a portion of a street or highway that meets any of the following:
- Is between a “work zone begins” sign and an “end road work” sign.
- For construction, maintenance, or utility work activities conducted by a work crew and more than 1 moving vehicle, is between a “begin work convoy” sign and an “end work convoy” sign.
- For construction, maintenance, surveying, or utility work activities conducted by a work crew and 1 moving or stationary vehicle exhibiting a rotating beacon or strobe light, is between either of the following points:
- A point that is 150 feet behind the rear of the vehicle or that is the point from which the beacon or strobe light is first visible on the street or highway behind the vehicle, whichever is closer to the vehicle.
- A point that is 150 feet in front of the front of the vehicle or that is the point from which the beacon or strobe light is first visible on the street or highway in front of the vehicle, whichever is closer to the vehicle.
Other areas of the regulation call for specific requirements around:
- Traffic control;
- Barricades for construction operations;
- Placement, removal, relocation, and use of traffic control devices from a moving vehicle; and
- More.
Note that some states have requirements for work zones and flaggers that fall under the state’s Department of Transportation regulations, in addition to the OSHA-related requirements listed here.
