Class, division

For 100 lbs NEW (45 kg NEQ) or less of demolition explosives, thin-cased or low fragmentation ammunition items, bulk high explosives, pryotechnics, and in-process explosives of Class/Division 1.1, the minimum distance to exposure listed above will be 670 ft (204m).... ... 

For all types of Class/Division 1.1 in quantities of 101 to 30,000 lbs NEW (46 to 13,600 kg NEQ), the minimum distance will be 1250 ft (380m), unless it can be shown that fragments and debris from structural elements of the facility or process equipment will not present a hazard beyond the distance specified. For items that have been evaluated adequately, a different minimum distance...may be used. 

For public traffic routes that are not possible sites for future targets and for other exposures permitted at public traffic route distances,. ..fragment...distance minima for Class/Division 1.1 may be reduced to 400 ft.... ... 

Although the transport of dry lead picrate is forbidden by the Department of Transportation (DOT) (49 CFR 172.101), the addition of water desensitizes it. No hazard classification is available from DOT for wetted lead picrate, but silver picrate, which is similar in sensitivity, may not be shipped when dry but is classified as a flammable solid (Hazard Class/Division 4.1) when it is wetted with water by at least 30 percent by mass. 

Hazardous (classified) locations have traditionally been designated by Class, Division, and Group. Equipment used in areas so designated is selected and systems are designed, based on requirements established for the classification. This approach is defined in Article 500 of the NEC and API 500.

MVDA is highly suitable for classifying differently loaded areas inside one emission impact monitoring raster screen. By this means the a priori class division, which is given by a knowledge of the structure of emission sources and the particular territorial situation, can be corroborated. 

Furthermore, one might try to explain the persistence of cultural divisions by the absence of some of the conditions for class consciousness discussed in 6.2.2. If, for instance, the turn-over rate of the work force is quite high, there may never be time to overcome the cultural prejudices and hostilities among the workers. This line of argument, while not implausible, forms a very weak reply to the objection. It says, essentially, that cultural divisions are not inherently stronger than class divisions. The former dominate the latter only under certain conditions, that may or may not obtain. Now there may be some who would argue that culture is invariably more important than class, but there is no need to accept this view in order to object to the Marxist view that the priority invariably is the other way around. 

Various types of hazardous atmospheres are classified to make it easier to discern the specific equipment needed to work in a given hazardous atmosphere. Most manufacturers use these classifications in their operating specifications. This classification system is clearly laid out in NFPA 497 and should be studied to get an understanding of the system. The most common classifications are Class, Division, Group, and Zone.
