Notable Confined Spaces - Unexpected Issues (AIHce EXP 2019 OnDemand)

Session will show what natural forces induce ventilation in isolated subsurface structures. Factors can include: air velocity along the ground surface and outside and inner temperature differences, which can exhibit annual repetitive patterns and peak values. This presentation integrates a video showing air movement outside and inside the structure with analysis of analytical data to determine influencing factor(s) and proposes a mechanism reflecting studies in fluid mechanics to explain ventilation of the airspace consistent with the well-mixed box model. Hazards in mining or tunneling in confined spaces and unique conditions encountered when planning and implementing controls for vertical depths of over 40 feet and horizontal tunnel runs greater than 200 feet will be discussed. Exposure scenarios will focus on typical particulates and gases, but also emphasize potential over exposures while transporting and handling materials through and out of tunnels.
Presenters: Neil McManus, NorthWest Occupational Health & Safety; Caroline Switzer, EPCOR Drainage Services, Canada.
