“…A previous participatory ergonomics (PE) study among construction workers from three trades set the foundation for our current study. In brief, we conducted a PE study among construction workers from three trades: floor laying, carpentry, and sheet metal [Jaegers et al, ; Dale et al, ] and seven contractors, following each project for approximately 6 months. We provided training to enable workers to identify ergonomic risks in work tasks such as high force, awkward postures, repetition, contact stress, and vibration, and to identify ergonomic solutions such as tools, equipment, scheduling, and work practices.…”
