Abstract: Sampling systems provide apparatuses for obtaining and assessing the composition of a fluid, typically air. Sampling systems allow industrial hygienists to assess the risks and determine the protective equipment that should be worn by personnel entering a specific environment. In one embodiment, a sampling system comprises a sampling container that draws air into its inner volume and the sampling periods are controlled by an automatic timer valve. The automatic timer valve may comprise a rotating disk or plate that provides fluid communication from the area to be sampled to the inner volume of the sample bag when apertures are aligned with inlet tube.

Abstract: The disclosure is directed to sampling bags having flexible walls. The sampling bags may have agile walls that include a shape memory component. The shape memory component tends to return the sampling bag to its initial shape. Such sampling bags may be used in a variety of sampling methods.

Abstract: Gas masks and canisters for gas masks have a chemical sorbent that protects the respiratory system of the wearer from gaseous compounds. The remaining service indication systems for respiratory protections systems provide a warning to the wearer that the capacity of the chemical sorbent to adsorb or absorb further compounds is nearly depleted. A remaining service life indication system has a computer memory device for storing information concerning the canister for determining an end of the service life of a gas mask, a canister and/or a cartridge and such devices from the input of various sensors.

Abstract: The disclosure is directed to a device for fluid sampling. The device may have two panels that are or may be adhered, attached or otherwise connected to opposite sides of a sampling bag having flexible walls. The panels may be used for conveniently inflating or deflating the sampling bag and obtaining fluid samples.

Abstract: The present invention is directed to containers for fluids. The containers may comprise a flexible wall, wherein the flexible wall comprises a metal alloy. The metal alloy may be any metal alloy that may be formed into a sheet including, but not limited to, some stainless steel alloys such as SST 304, SST 309, SST 316, SST 316L, SST 321, low carbon stainless steels and nickel-titanium alloys known as Nitinol.

Abstract: An apparatus is provided for testing equipment located in a local environment by presenting a detectable indicator gas therein. The apparatus has a container portion, a chemical substance stored in the container portion, a pump operable to draw air into the container portion and in contact with the chemical substance to generate a detectable indicator gas, and an outlet to the container for directing the indicator gas into the local environment. Further, the pump is integrally formed as one piece with the container portion. Preferably, the pump is a manually squeezable polymeric bulb that is joined (e.g., by molding) seamlessly with the container portion.
