Section 296-62-09001. Definitions.

(1) "Physical agents" shall mean, but are not limited to: Illumination, ionizing radiation, nonionizing radiation, pressure, vibration, temperature and humidity, and noise.

(2) "Nonionizing radiation" as related to industrial sources, means electromagnetic radiation within the spectral range of approximately 200 nanometers to 3 kilometers including ultraviolet, visible, infrared and radiofrequency/microwave radiation. The electromagnetic spectrum is shown graphically in Figure 1 below.

(3) Pressure is a barometric force. Positive pressure would be that above 14.7 lbs. per square inch absolute and negative pressure would be that below 14.7 lbs. per square inch absolute. 14.7 lbs. per square inch equals 760 mm. mercury.

(4) "Vibration" means rapid movement to and fro or oscillating movement.

(5) "Noise" means unwanted sound or loud discordant or disagreeable sound or sounds.

(6) "Temperature" means the degree of hotness or coldness measured by use of a thermometer.

(7) "Radiant heat" means infrared radiation emitted from hot surfaces.

(8) "Relative humidity" means the percent of moisture in the air compared to the maximum amount of moisture the air could contain at the same temperature.
