JUMP TO FULL CODE CHAPTER
- When Division 1.1 and 1.2 explosives are located in the same site, determine the distance for the total quantity considered first as if the total quantity were in Division 1.1 and then as if the total quantity were in Division 1.2. The required distance is the greater of the two. When the Division 1.1 requirements are controlling and the TNT equivalent of the Division 1.2 explosive is known, the TNT equivalent weight of the Division 1.2 explosives shall be added to the total explosive weight of Division 1.1 explosives to determine the net explosive weight for the Division 1.1 distance determination, for purposes of quantity-distance requirements in accordance with FC Table 3304.5.2(2).
- When Division 1.1 and 1.3 explosives are located in the same site, determine the distances for the total quantity considered first as if the total quantity were in Division 1.1 and then as if the total quantity were in Division 1.3. The required distance is the greater of the two. When the Division 1.1 requirements are controlling and the TNT equivalent of the Division 1.3 explosives is known, the TNT equivalent weight of the Division 1.3 explosives shall be added to the total explosive weight of Division 1.1 explosives to determine the net explosive weight for the Division 1.1 distance determination, for purposes of quantity-distance requirements in accordance with FC Table 3304.5.2(2) or 3304.5.2(3), as appropriate.
- When Division 1.1, 1.2 and 1.3 explosives are located in the same site, determine the distances for the total quantity considered first as if the total quantity were in Division 1.1, next as if the total quantity were in Division 1.2 and finally as if the total quantity were in Division 1.3. The required distance is the greatest of the three. When the Division 1.1 requirements are controlling and the TNT equivalent of the Division 1.2 and Division 1.3 explosives are known, the TNT equivalent weight of the Division 1.2 and Division 1.3 explosives shall be added to the total explosive weight of Division 1.1 explosives to determine the net explosive weight for the Division 1.1 distance determination, for purposes of quantity-distance requirements in accordance with FC Table 3304.5.2(2).
- For any composite pyrotechnic material and Division 1.1 or Division 1.3 explosives, the sum of the net weights of the pyrotechnic material and the explosives shall be used for the distance determination, for purposes of quantity-distance requirements in accordance with FC Tables 3304.5.2(2) and 3304.5.2(3).
