ABSTRACT:
An instrument for use on a marine vehicle including a sensor for determining the concentration of carbon monoxide (COC) present on the vehicle, an LED indicator for visually displaying the concentration, a microprocessor using a mathematical formula for calculating the health hazard to a person on the vehicle occasioned by the level of carbon monoxhemoglobin %COHb in the blood of that person resulting from breathing concentrations of carbon monoxide over a period of time. The instrument also determines for determining the health hazard condition in terms of long term exposure to a low COC level, moderate term exposure to a moderate COC level, and short term exposure to a high COC level, and in addition visually and audibly indicates the health hazard conditions. A method for the operating instrument, and a method of testing operativeness of the instrument are also provided.
