The objectives of this study were to clarify physiological loads under tropical conditions and to establish a proper working time design for tropical forestry operations. The research was conducted in East Kalimantan, Indonesia, in 1995. In this research, physiological loads and thermal conditions were investigated under various conditions, i.e., in forests and nurseries, on roads and at logged-over areas. Using the standards of the American Conference of Governmental Industrial Hygienists (ACGIH), a structure of work to rest proportions could be designed properly. Results showed that felling and cutting trees and weeding in the forest could be done continuously early in the morning and with 25% rest time for the remainder of the work day. Spreading fertilizer at the nursery could be done almost continuously all day. Road maintenance could be performed continuously during early morning but 50–100% rest time was needed for the remainder of the day. At logged-over areas, path clearing using chainsaws and soil hoeing required 50% rest early in the morning and 75–100% rest after that time, while planting required 25% rest early in the morning and 50–100% rest after that time. In conclusion, work done at logged-over areas required a greater percentage of rest time than work at other locations except early in the morning.
