Michigan Regulations for Lifting Employees with Forklifts

In Part 21 of the General Industry Safety Standards, LARA requires that:

"An employee shall not be lifted or transported, except when a platform is attached ot the forks by enclosed sleeves, a safety chain, or  a mechanical device in such a manner that the platform cannot tip or slip."

- R 408.12167 Rule 2167

Always use forklifts for their intended purpose.  Lifting employees with a forklift is not safe, unless it is specifically designed for that purpose.
