Scope

1.1 This practice may be used to determine the level of specific harmful airborne contaminants within a vehicle operator enclosure under standardized test conditions. The air exchange rate, air pressure relative to ambient conditions, air temperature, and relative humidity maintained within the enclosure during the test are also determined. Operator-introduced contaminants are not addressed by this practice.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Significance and Use

There are concerns about the potential for excessive exposure of the operators of self-propelled agricultural vehicles to toxic agricultural chemicals when transporting or applying these materials, or both. A need exists for suitable procedures for determining the amount of toxic chemical contaminants in the vehicle operator environment when official testing is required.

The purpose of this practice is to provide a practical, reliable, and reproducible procedure for testing the performance of operator enclosure ventilating or air conditioning systems, or both, relative to the maintenance of safe environmental conditions with regard to toxic material contamination within the enclosure under static (laboratory) or dynamic (field) conditions, or both.
