Safe, Harmful Working Postures, Construction, OWAS.
This study appraised working postures adopted by two groups of construction workers in Southwestern Nigeria. The objective was to measure and compare the level of safe postures in manual lifting tasks among the workers. Using Ovako Working Postures Analyzing System (OWAS), 844 working postures involving 250 healthy Bricklayers (BL) and Bricklayers’ Assistants (BA), were analyzed. 36% of the total postures observed were classified as Action Group 1 (AG- 1) - not harmful, while the rest postures call for ergonomics interventions. AG-3 and AG-4 (harmful) occupied more than 49% of the total recorded postures. The higher percentage among the safe postures (58%) was recorded in lifting task performed by BA. The study revealed that the degree of safe postures among the groups of workers is comparatively low. Necessary ergonomics measure is required to improve on AG-1 postures among the workers. Such control will reduce the unsafe conditions characterizing manual lifting activities in construction tasks.
