Selected head and facial dimensions of mine rescue team personnel.
Am Ind Hyg Assoc J 1978 Jul; 39(7):576-578
A study of selected head and facial dimensions of mine rescue team personnel was undertaken to aid in the design of full face masks for self contained rescue breathing apparatus. Following a mine fire or explosion, rescue personnel will enter areas of the mine that contain toxic gases that are immediately hazardous to life. It is imperative that the face mask fit the wearer properly to prevent inward leakage of gases when the pressure in the mask becomes negative during inspiration. Thirteen facial characteristics useful for face piece and nose cup design and three head characteristics useful for helmet design were measured. Leakage data on masks indicate that many masks do not fit the general male population properly. In addition, while the facial and head dimensions of the civilian Caucasian male population is now reasonably well known, those of the female and nonCaucasian industrial populations are not. Furthermore, an increasing segment of these groups is required to wear personal protective equipment, but anthropometric surveys to provide the required dimensions are unavailable.
