Since exposure of a spontaneously combustible material to air has obvious consequences, loss of containment or other means of air exposure is usually the most important issue regarding what can go wrong. It should be noted that pyrophoric materials often exhibit one or more other reactivity hazards as well, such as water reactivity. Possible causes of uncontrolled reactions associated with pyrophoric and other spontaneously combustible materials include abnormal events such as the following ... [Pg.54]

If you are certain that NO pyrophoric or other spontaneously combustible materials are present, then proceed to Question 8. Table 3.2 gives categories and examples of pyrophoric materials. More extensive lists that include less common chemicals, including metals, can be found in Urben (1999, 2 341-346). Other spontaneously combustible substances are tabulated by their proper shipping names and UN/NA numbers in the U.S. Department of Transportation regulation 49 CFR 172.101. [Pg.55]

The first analysis performed on the concentrated DPR streams was for pyrophoricity according to the UN Test Method for Division 4.2 (Spontaneously Combustible Materials). The results of this test came back Non-Pyrophoric. Flashpoint testing (Tag Open Cup ASTM D 1310) also gave unexpected results with a flash point of >100 °C. This places the material into the category of a Non-Combustible Liquid. [Pg.127]
