Appendix A


85 HI


Heat Index from Temperature and Humidity

 The following chart delineates the relative humidity level that shall be reached and maintained to achieve a Heat Index value of 85.

 When air temperature in any part of the kennel or kennel housing facility, where any dog is housed, kept or present, including primary enclosures rises above 85° Fahrenheit the following relative humidity levels shall be achieved and maintained.

Temperature (air)
in Fahrenheit
Relative Humidity (RH)
86° Fahrenheit 40% RH or less
87° Fahrenheit 34% RH or less
88° Fahrenheit 28% RH or less
89° Fahrenheit 21% RH or less
90° Fahrenheit 11% RH or less
91° Fahrenheit 6% RH or less
92° Fahrenheit 1% RH or less

 Note: At temperatures in excess of 92° Fahrenheit there is no relative humidity level that will allow an HI of 85 to be achieved.

90 HI
Four-Hour Window


Heat Index from Temperature and Humidity

 The following chart delineates the relative humidity levels that may not be exceeded at any time.

 Once the air temperature in any part of the kennel or kennel housing facility, where a dog is housed, kept or present, exceeds 85° Fahrenheit, the kennel owner shall have no more than 4 hours to accomplish and maintain a Heat Index of 85 HI or lower, as required by this chapter. At no time during that 4-hour time period or at any other time shall the Heat Index value ever exceed 90 HI in any area, room or part of the kennel or housing facility, where a dog is housed kept or present, including primary enclosures.

Temperature (air)
in Fahrenheit
Relative Humidity (RH)
86° Fahrenheit 58% RH or less
87° Fahrenheit 53% RH or less
88° Fahrenheit 48% RH or less
89° Fahrenheit 43% RH or less
90° Fahrenheit 39% RH or less
91° Fahrenheit 35% RH or less
92° Fahrenheit 30% RH or less
93° Fahrenheit 25% RH or less
94° Fahrenheit 20% RH or less
95° Fahrenheit 13% RH or less
96° Fahrenheit 10% RH or less
97° Fahrenheit 7% RH or less
98° Fahrenheit 3% RH or less

 Note: At temperatures in excess of 98° Fahrenheit there is no relative humidity level that will allow an HI of 90 to be achieved.
