Street explosives

The most important group of chlorate expls is listed under " Chedddtes or "Street Explosives". They are described in Voi 2, pp Cl55 to Cl60... 

Blake Explosive, proposed in 1865 for filling grenades and torpedoes consisted of K chlorate and sulfur. It was the predecessor of Sprengel Explosives, known as Cheddites or Street Explosives Ref Stettbacher(1933),309...

The first Cheddites or Street Explosives studied and approved for manuf at the Poudrerie de Vonges by the French "Commission des Substances Explosives , beginning 1897, had the compns listed in Table l(Refs la,5,13,15,... 

Many chlorate mixtures, particularly those which contain sulfur, sulfides, and picric acid, are extremely sensitive to blows and to friction. In the Street explosives, later called Cheddites because they were manufactured at Chedde in France, the chlorate is phlegmatized by means of castor oil, a substance which appears to have remarkable powers in this respect. The French Commission des Substances Explosives in 1897 commenced its first investigation of these explosives by a study of those which are listed below, and concluded 35 that their sensitivity to shock is...

Turpin s expls were soon superseded by Cheddites (see Vol 2, C155-L to C164-R), introduced by Street in 1897 Refs 1) Commission des Substances Explosives, MP 11, 53-56 (1901) 2) Daniel (1902),... 

Objects in the vicinity of an explosion can often serve as useful post-blast witnesses. Thus for large explosions damage to structural elements of buildings, street furniture, motor vehicles, and glazing can all prove informative. A number of authors have published studies that provide guidance on both damage assessment techniques and interpretation of the data [2-7]. 

Your occupational health and safety officer at work can and should tell you whether chemicals you work with are dangerous and likely to be carried home on your clothes, body, or tools. Ask if you should shower and change clothes before you leave work, store your street clothes in a separate area of the workplace, or launder your work clothes at home separately from other clothes. The Occupational Safety and Health Administration (OSHA) requires Material Safety Data Sheets (MSDSs) for many chemicals used at your place of work. MSDS information should include chemical names and hazardous ingredients, and important information such as fire and explosion data, potential health effects, how you get the chemical(s) in your body, how to properly handle the materials, and... 

Heroin (Schedule I) is the acetylated form of morphine. The derivatization makes it more lipophilic and heroin therefore has about three times the potency of its morphine parent. Street heroin is rarely more than 10% heroin, the rest being some type of filler. The summer of 1989 saw what the L.A. Times reported as an "explosion" of Southeast Asian heroin with average purities of 48% to 51 %, much higher than is expected by the user. The purer heroin makes it easier to smoke, a practice used by crack addicts... 

The addition to potassium chlorate of vegetable oils, fats or mineral oils in which aromatic nitro compounds are dissolved, as recommended by Street [72], proved to be a milestone in the development of chlorate explosives. The application of an admixture of castor oil was particularly useful. The presence of oils and fats in the explosives reduced their sensitiveness to friction and impact, and the oily ingredient conferred a slightly plastic consistency.

RDX is used in most of the better explosives in service today, ranging from composition B, the standard bomb-filler used by the Air Force, to composition C-4, the best of the plastic explosives. The following process is the cheapest and easiest method I ve found for RDX production. It uses only three chemicals—ammonium nitrate, acetic anhydride, and paraformaldehyde. All three arc readily available, but procuring the acetic anhydride can be a bit touchy, however, as it is widely used in the production of the illegal thug methamphetamine, or "crystal," as it s called on the streets. 

On March 23, 1944, however, something happened. On this day, as on many other days before, the police regiment Bozen , which was comprised almost entirely of South Tyroleans, marched through the Via Rasella. As the regiment passed by a street-sweeper s cart, an enormous explosive charge in the cart, mixed with iron shrapnel, blew up. 32 of the German policemen were killed instantly, another 10 died later of their injuries. 60 policemen were badly wounded. 

It was the sort of thing you expected in the Street of Alchemists. The neighbours preferred explosions, which were at least identifiable and soon over. They were better than the smells, which crept up on you. 

Ethyl diazoacetate is available from Aldrich Chemical Co., 2371 North 30th Street, Milwaukee, Wisconsin. Diazoacetic esters are potentially explosive and therefore must be handled with caution.2...
