Study of the Use of Personal Equipment in Low Coal. Experiments on Personal Equipment for Low Seam Coal Miners: IV. Incorporating Coiled Cord into Cap Lamp Battery Cords. Phase II Report Number 4

摘要

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 describes a study designed to evaluate a proposed modification in the cap lamp battery cord intended to reduce the incidence of snagging and catching of the cord. A three-phase evaluation was performed comparing a prototype with the standard, currently available cord.
