Chamber Tests with Human Subjects III. Design, Operation, and Calibration of a Chamber for Exposing Forearms to H Vapor
Abstract
This report describes the design, calibration, and operation of a chamber for the exposure of the forearms of human subjects to the vapors of chemical warfare agents. The construction of the chamber is such that the temperature, relative humidity, air velocity, and concentration of vesicant agent can be controlled closely over a wide range of conditions, Tests have been made to correlate this "arm chamber" with the large chamber now being used at this Laboratory in evaluating Navy Issue Protective Clothing, Ointments, and Masks. It has been found in these tests that in exposing forearms to H vapor at 90 deg plus or minus 1 deg F. and 65 plus or minus 3% R.H., with the rest of the body at 70 - 80 deg F. and 20 - 30% R.H., twice as great a CT value (mg, min./m3) is required to produce the same degree of burn as when the entire body is equilibrated at 90 deg F. and 65% R.H.
