Characteristic properties, cautions, markings required Each outside box must be plainly marked on top and on one side or end-"High explosives-Dangerous." Each outside box must be plainly marked on top and on one side or end: "High explosives-Dangerous." Fireworks that can be exploded en masse by dropping the completed shipping package from a height of 6 feet or by the impact of a rifle bullet if found safe for transportation. Solid explosives which can be caused to detonate, when unconfined, by contact with sparks or flame such as produced by safety fuse or an electric squib; or which can be exploded in the Bureau of Explosives' impact apparatus in more than 50% of the trials under a drop of less than 4 inches. Blasting caps are small tubes, usually made of an alloy of either copper or aluminum, or of molded plastic, closed at one end and loaded with a charge of initiating or priming explosives, Class A-Type 4, either with or without other suitable explosives. The total weight of explosives per unit shall not exceed 150 grains. Blasting caps which have been provided with a means of firing by an electric current, and sealed, are known as electric blasting caps. Do not stow blasting caps with any high explosive. Do not handle blasting caps at the same time as high explosives are being loaded. Each outside box must be plainly marked with the appropriate descriptive name of the contents as: "(number) Blasting caps-Handle carefully;" "(number) Electric blasting caps-Handle carefully;" "(number) Blasting caps with safety fuseHandle carefully." "(number) Blasting caps with metal clad mild detonating fuse-Handle carefully.' In addition each box must bear the marking "Do not stow or load with any high explosive." Bursters (explosive).--. Detonating fuzes, class A explosives, with or without radioactive components. Detonating fuze parts containing an explosive. Supplementary charges (explosive). charges consist of a casing containing a high explosive and are used to increase the intensity of explosion of the detonator of a detonating fuze. Bursters consist of a casing containing a high explosive and are used to rupture a projectile or bomb to permit release of its contents. Detonating fuzes, class A, are used in the military service to detonate the high explosive bursting charges of projectiles, mines, bombs, torpedoes and grenades. In addition to a powerful detonator, they may contain several ounces of a high explosive, such as tetryl or dry nitrocellulose, all assembled in a heavy steel envelope. They may also contain a small amount of radioactive component. Radiation on the surface of any detonating fuze having a radioactive component shall not exceed 100 milliroentgens per hour. Detonating fuzes that are so made and packed that they will not cause functioning of other fuzes, explosives, or explosives devices, in the same or adjacent containers are classed as class C explosives. Do not stow detonating fuzes with any high explosives; and Do not load at the same time that high explosives are being loaded. Each outside container must CHARGES (EXPLO- Initiating explosives (in bulk in dry condition). Initiating explosives (diazodinitrophenol wet with not less than 40% by weight of water) Initiating explosives (ful minate of mercury wet with no less han 25% by weight of water) Initiating explosives (guanyl nitrosamino guanylidene hydrazine wet with not less than 50% by weight of water) Initiating explosives (lead azide, wet with not less than 20% by weight of water). Detonating primers are de vices for commercial use which contain a detonator and an additional charge of explosives, all assembled in a suitable envelope. The total weight of explosives is more than 150 grains per unit. Do not stow detonating primers with any high explosive. Do not load at the same time as high explosives are being loaded. Each outside container must be plainly marked "Detonating primers-Handle carefully." For safety in transportation these substances are packed wet with water. Therefore, observe outside containers for signs of leakage. Reject leaking containers or ones showing signs of having leaked. Do not handle these substances at the same time as high explosives are being loaded. In handling and in stowage, avoid exposure to shock, friction, heat, and open flame. Sufficient outage in outside containers must be allowed to prevent rupture of container in freezing weather, or a mixture of denatured ethyl alcohol and water may be used to prevent freezing in transit. Each outside barrel, drum, or keg must be plainly marked "Initiating ExplosiveDangerous-Do not store or load with any high explosive." __do_. .do do.. |
