Lifting and Heat Stress Limits
Two workplace limits for safety and ergonomics work. Lifting: the Revised NIOSH Lifting Equation of NIOSH Publication 94-110, RWL = LC × HM × VM × DM × AM × FM × CM in the manual's US form (51 lb, inches) or metric form (23 kg, centimetres), with the frequency and coupling tables of the manual, the origin and the destination of a lift that needs control, the Lifting Index, and for several tasks the multi-task procedure (frequency-independent and single-task weight limits and indices, the Composite Lifting Index), with the lowest multiplier of each task named as the first thing to redesign. Heat stress: the wet-bulb globe temperature indoors or outdoors from the natural wet-bulb, globe and dry-bulb readings, the one-hour time-weighted WBGT and metabolic rate of a work and rest schedule, the NIOSH recommended exposure limit for acclimatized workers and recommended alert limit for unacclimatized workers of Publication 2016-106, a clothing adjustment, the work minutes per hour that meet the limit, the acclimatization plan, and the National Weather Service heat index with its risk class. The default lifting job is the manual's depalletizing example (five tiers, Composite Lifting Index 1.4).
