Document Summary
] distance multiplier (dm) : dm = (. 82+(4. 5/d)) , d = vertical travel distance (cm) between origin and destination of the lift. Freq < . 2 lifts/min then freq = . 2. Freq > 15 lift/min then fm = 0, rwl = 0. For intermittent lift, compute average # of lifts in. 15 min: coupling multiplier (cm) : classification of the quality of the hand-to-object coupling, found using given tables. Assumption and limitations of the niosh lifting guide. Manual work activities other than lifting assumed to be minimal. Equation does not include task factors to account for unpredictable situations such as shifting loads. Show-floor coefficient of friction of at least . 4 (. 5 preferred) Lifting and lowering tasks are assumed to pose same risk. Tasks involving one-handed lifts, lifting while sitting/kneeling, lifting a constrained work area are not addressed. Select unit system (1 lb = . 45kg, 1 in = 2. 5 cm) The seven components of rwl must be between 0 and 1.
