TI  - A comparison of different postures for scaffold end-frame disassembly.
PG  - 507-13
AB  - Overexertion and fall injuries comprise the largest category of nonfatal injuries 
      among scaffold workers. This study was conducted to identify the most favourable 
      scaffold end-frame disassembly techniques and evaluate the associated slip 
      potential by measuring whole-body isometric strength capability and required 
      coefficient of friction (RCOF) to reduce the incidence of injury. Forty-six male 
      construction workers were used to study seven typical postures associated with 
      scaffold end-frame disassembly. An analysis of variance (ANOVA) showed that the 
      isometric forces (334.4-676.3 N) resulting from the seven postures were 
      significantly different (p < 0.05). Three of the disassembly postures resulted in 
      considerable biomechanical stress to workers. The symmetric front-lift method 
      with hand locations at knuckle height would be the most favourable posture; at 
      least 93% of the male construction worker population could handle the end frame 
      with minimum overexertion risk. The static RCOF value resulting from this posture 
      during the disassembly phase was less than 0.2, thus the likelihood of a slip 
      should be low.
