Nev. Admin. Code § 554.400 - Methods of disinfecting broomcorn

Broomcorn and articles made of broomcorn must be disinfected by using one of the following methods:

1. Vacuum fumigation (HCN). Three pounds of liquid hydrocyanic acid or its equivalent per 1,000 cubic feet of air space must be injected into a vacuum at a temperature of not less than 60 degrees Fahrenheit. The gas must be injected in at least a 28-inch vacuum sustained for a period of at least 3 hours.

2. Steam sterilization under vacuum. Air pressure in a chamber must be reduced to a 25-inch vacuum. Steam must then be introduced until a positive pressure of 10 pounds is obtained. This pressure must be sustained until a constant temperature in all parts of the chamber is attained.

3. Atmospheric fumigation in a gastight chamber using a dosage schedule of 2 1/2 pounds of methyl bromide per 1,000 cubic feet of chamber space for 6 hours at temperatures of at least 70 degrees Fahrenheit.
