The forest sector is a high
-
risk economic sector in
Latvia, one in which manual work,
awkward postures, the tightening up of individual muscle groups, and work monotony still exists.
The aim of this study was to analyse the physical workload and fault modes, and their effects on
the sawing and packing proce
sses in woodworking when considering potential ergonomic
solutions. Results show that packing operators and saw operators alike are exposed to severe
loads, and these results coincide with survey results in which employees in these professions
complain abo
ut the physical load and mention lower back pain. Fault modes and their effects on
the sawing and packing processes were analysed using Failure Mode and Effects Analysis, and
the main errors which were revealed in packing operations were related to machine
ry and lifting
equipment, as well as to ergonomics and errors involving the human factor. The risk priority was
calculated in terms of a figure. Financial indices were compared
before and after any potential
improvement in the sawing and packing processes.
Analysis proves that investments in the
improvement of ergonomics in relation to the automation of the production process saves human
resources and is economically favourable when it comes to ensuring the sustainable development
