Type C Organic Peroxides are defined as which statement?

• A. any organic peroxide that cannot detonate or deflagrate rapidly
• B. any organic peroxide that detonates rapidly
• C. any organic peroxide that detonates partially but does not deflagrate rapidly and shows no violent effects under heated confinement; or does not detonate at all, deflagrates slowly, and shows no violent effects under heated confinement; or does not detonate or deflagrate and shows medium effects when under heated confinement
• D. any organic peroxide that is inert

Answer: (C)

Type C Organic Peroxides describe materials that have limited explosive potential under heat and confinement. They may detonate only partially and not deflagrate rapidly, and under heated confinement show no violent effects; or they may not detonate at all but deflagrate slowly and still show no violent effects under heated confinement; or they may neither detonate nor deflagrate and show medium effects when under heated confinement. This captures the idea that these peroxides are hazardous, but their reactions under heat and confinement are less violent than those in more dangerous categories. The other descriptions imply rapid detonation or inertness, which do not fit this classification.
