ABSTRACT:
Explosive fumes in the lower portion of a power boat are detected by providing a manually collapsible elastomeric bulb, forming a one-way pump, adjacent a remote station on the boat, the bulb having its inlet remotely connected by a long inlet tube to a lower portion of the boat hull where such fumes normally collect. The outlet of the bulb is connected to a nose mask having an orifice therein to increase the velocity of air passing into the mask. By placing the mask over a person's nose and successively and quickly collapsing the bulb, high velocity bursts of air are directed into the person's nose so that he may readily detect any fumes.
