11 Collaborations Interdisciplinary team The Center for Construction Research and Training (CPWR) Grant # U60 OH Construction ergonomics efforts CPWR resources into practice Masonry R2P Partnership BAC - IMI 10

12 Significance Construction Work-related Musculoskeletal Disorders (WRMSDs) are decreasing. Brickmasons 142,000 in US (1.6%) WRMSDs #1 overexertion (66.5 per 10,000 FTE) #2 back injuries (45.3 per 10,000 FTE) 11 The Construction Chart Book, CPWR 2013

13 Physical Demands: How much does a bricklayer lift? 1 Day: 3.8 tons* 1 Week: 19 tons 1 Year: 950 tons * Based on an average of 200 blocks per day, 38 lbs each 12 April 21, 2016

14 Construction solutions Possible solutions not in the locus of control of masons 1) light weight block 2) H block or A block 3) 60 # bags or half weight cement bags 4) mechanical scaffolding 5) mortar mixers 6) grout delivery systems 7) half size pallets (of brick) Possible solutions within the locus of control of masons 1) lift teams with 10 block 2) ergonomic trowel / other tools 3) keep bricks/block at work height (between knees and shoulder) 13

15 SAVE Aims 1. Develop & integrate SAVE into apprenticeship training 2. Measure the effectiveness of SAVE Randomized controlled trial 3. Finalize & disseminate SAVE broadly 14 National Occupational Research Agenda (NORA2) Strategic Goals 7.0: MSDs 8.0: Construction safety and health culture 11.0: Training

20 E3: Cumulative Trauma Click Here 19

21 E3: Cumulative Trauma Lab Activity Key Points: Acute trauma is a significant injury that usually occurs in response to a single, identifiable event (e.g. a fall, being struck by a dropped object, etc) Cumulative trauma is the breakdown, over time, of muscles, tendons, or ligaments. Each instance of trauma is not notable, but as these build up, the body becomes more susceptible to acute trauma, and disabling injuries can emerge. Small non-ergonomic positions and movements can lead to injury over time. Objective: Understanding the difference between acute and cumulative trauma. Understand how small positions and movements can lead to injury over time Activity: Acute vs. Cumulative Each person gets to break: One piece of wood One piece of wire 20
