Designed for retailers and safety experts, this NIOSH booklet has a goal to prevent MMH (manual material handling) injuries in grocery stores. MMH injuries, also called overexertion injuries, account for 60% of the injuries and lost work in select retail businesses. This 23-page booklet has 13 unique illustrations showing employees in a grocery store using various mechanical assist devices. This booklet was inspired by the Ergonomic Guidelines for Manual Material Handling.
