Can ergonomics affect efficiency and productivity in the construction industry? Is it a fallacy?

by Brian Roberts, Matthew Pierce
The construction work force is aging at an alarming rate with fewer skilled tradesman entering this workforce. Profit margins are thinner than ever. Through research and analysis conducted at CNA, we have gained an understanding of job site ergonomic exposures, specific job tasks, and work force limitations within the construction trades that impact productivity, efficiency, and risk factors. This presentation highlights a case study that focuses on all these areas. It also shows that using this ergonomic approach has enhanced productivity and reduced risk factors associated with musculoskeletal injuries. View presentation

Lean ergonomics successful implementation within a kaizen event

by Carrie Scheel, EdD, OTR, Dr. Chris Zimmermann, PhD, PT
The purpose of this case study was to evaluate the impact of incorporation of participatory ergonomics within a kaizen event at a local brake manufacturer. Members of the kaizen event group were divided into three teams: forecasting, time observation, and layout, with the ergonomic consultants acting within all three teams. The teams assembled for the kaizen event allowed for integration of ergonomic principles within the lean implementation process. Kaizen event results included reduced cycle times, travel distances, and square footage. Changes in parts presentation and equipment usage led to 67 to 100 percent reductions in existing ergonomic risk factors. By working as an integral part of the kaizen event teams, the ergonomic consultants were able to influence workplace and work practice redesign without being the driving force. Through active participation by both management and employees in the change process, ergonomics was successfully implemented within the kaizen event. View paper

Ohio BWC safety grant lift table/material handling intervention outcomes

by Jean Weaver, Chris Hamrick, Kaori Fujishiro, Catherine Heaney, William S. Marras
This presentation will briefly explain the Ohio Bureau of Worker's Compensation Safety Grant and provide information regarding the implementation of the safety grant in 140 company work areas that purchased lift table and material handling ergonomic equipment. Baseline (pre-intervention) and follow-up (post intervention) data will be provided for the work areas. Outcomes of the ergonomic interventions will be discussed in regard to reduced injury rates, lost days, and restricted days. View paper

Shiftwork, work scheduling and safety: How much is too much?

by Wayne Maynard, George E. Brogmus
The ergonomic design of a work schedule can have a significant impact on productivity and safety. Overtime is not the only aspect of work scheduling that can impact injury risk. While research continues to confirm findings that relate work scheduling factors to injury risk, only a few researchers have begun to consolidate these findings into useful models. These models consider the combination of factors that have an impact on injury risk including time of day (e.g., day shift, night shift, etc.), hours worked per shift, number of consecutive shifts, and time between rest breaks. This presentation will provide an overview of research regarding work scheduling factors and modeling, present two models useful for evaluating a work schedule including the United Kingdom Health and Safety Executive Fatigue Index and Risk Index calculator and conclude with overall guidelines on shiftwork design and injury prevention.

A survey of global MMH evaluation techniques

by Tom Albin 
This presentation will introduce the participant to techniques used to assess the acceptability of manual materials handling (MMH) tasks across the world. Particular attention will be provided to the differing approaches used in the United Kingdom and Germany to implement the European Community Lifting Directive, and to the recommendations of the International Standards Organization (ISO) with regard to lifting and carrying.
