The objective of this study was to determine optimal personal equipment design for use in low coal based on ergonomic, biomechanic, and safety considerations. This report compares a proposed 10/60 "piggyback" o2-generating, self-rescue unit with the standard CO self-rescue unit with respect to work task interference. A simulated low seam coal mine was constructed and workers performed locomotion, shoveling, cart pushing, and timbering tasks with the 10/60 and standard self-rescue units attached to their belts. Task completion time was longer on all tasks when wearing the 10/60 units, although only locomotion was statistically significant. The 10/60 units were bumped over 100 pct more often than the standard self-rescuers. It is recommended that the design for the proposed 10/60 units include (1) extra durable containers to withstand the added abuse they are likely to receive by low coal miners and (2) extra consideration toward preventing the devices from slipping on the belts while working.
