Patent ID: 6929200

Claim:
Method for preventing soaked asbestos from freeing airborne particles, comprising the following sequential steps affecting the temperature surrounding the asbestos: a) heating the asbestos in a first surrounding temperature value located between 125° F. (52° C.) and 175° F. (79° C.) and maintaining the asbestos in this first surrounding temperature value until the asbestos changes to a uniform pale russet-red color; b) increasing the surrounding temperature from said first temperature value to a second temperature value located between 225° F. (107° C.) and 275° F. (135° C.) and maintaining the asbestos in this second surrounding temperature value until the asbestos changes to a uniform dark russet-red color; c) increasing the surrounding temperature from said second temperature value to a third temperature value located between 325° F. (163° C.) and 375° F. (191° C.) and maintaining the asbestos in this third surrounding temperature value until the asbestos changes to a uniform dark orange color; d) increasing the surrounding temperature from said third temperature value to a fourth temperature value located between 425° F. (218° C.) and 475° F. (246° C.) and maintaining the asbestos in this fourth surrounding temperature value until the asbestos changes to a uniform red color; e) increasing the surrounding temperature from said fourth temperature value to a fifth temperature value located between 525° F. (274° C.) and 575° F. (302° C.) and maintaining the asbestos in this fifth surrounding temperature value until the asbestos changes to a uniform grey color; f) increasing the surrounding temperature from said fifth temperature value to a sixth temperature value located between 625° F. (329° C.) and 675° F. (357° C.) and maintaining the asbestos in this sixth surrounding temperature value until the asbestos changes to a uniform opaque white color; and g) decreasing the surrounding temperature from said sixth temperature value to an ambient temperature value.
