Caps, toy

Pyrotechnic substances include those chemicals or mixtures that undergo combustion or explosive deflagration to produce heat, light, sound, gas, or smoke. 

Pyrotechnic ammunition provides pyrotechnic effects for military or civil defense purposes by combining a pyrotechnic chemical with one or more of the following items

This combination has, in the past, been the base of various impact sensitive pyrotechnics, described by Haarmann [1] and more recently on the Internet, including reference to a report [2] of a mere 60-70 kg, dispersed in children s toy caps, demolishing a building in an accidental explosion. Red phosphorus is a material of variable composition and reactivity, so unreliability is to be anticipated. There have been passivating components in most of these mixtures, it is suggested that the pure dry powders will often react on contact. For the more reactive white allotrope ... 

Part 3 of BS7114 is concerned with the methods of testing of fireworks and certain items of auxiliary equipment such as rocket launchers. In essence, the standard calls up chemical and physical test methods that are applied to all types of firework, from toy caps to large rockets. Fireworks that are incomplete or not intended for sale to the general public are excluded. 

AMORCE A toy cap that consists of a paper envelope containing explosive composition and which forms part of a roll. 

CATEGORY 1 EiREWORKS Fireworks which are suitable for use inside houses (e.g. toy caps, party poppers and cracker snaps). 

Red phosphorus is mixed as a water slurry with potassium chlorate for use in toy caps and noisemakers. These mixtures are quite sensitive to friction, impact, and heat, and a large amount of such mixtures must never be allowed to dry out in bulk form. Red phosphorus is also used in white smoke mixtures, and several examples can be found in Chapter 8. 

Primary explosives explode from shock, from friction, and from heat. They are used in primers where it is desired by means of shock or friction to produce fire for the ignition of powder, and they arc used in detonators where it is desired to produce shock for the initiation of the explosion of high explosives. They are also used in toy caps, toy torpedoes, and similar devices for the making of noise. Indeed, certain primary explosives were used for this latter purpose long before the history of modern high explosives had yet commenced. 

In conclusion, lead, antimony, and barium may be encountered in pyrotechnics, in both fireworks and flares. Lead and antimony were present in toy caps but were not found occurring together. Antimony-only was detected in matches. None of these sources should be confused with FDR particles as their morphology and/or elemental content differs. (The text on toy caps, matches, flares, and fireworks represents the conclusions of the work conducted, as the details and results were lost in the terrorist explosion at the NIFSL in September 1992.)... 

The detonator (discriminating impact fuse) is a brass cup 3/16 V3/16 The wall thickness is about half that of a conventional primer. The Interior of the cap Is coated with a shock sensitive explosive, probably the same composition found in toy pistol caps (Pottasiym Chlorate, Red Phosphorus and Black Antimony Sulfide). The volume used is also about that of a toy cap. The cup is seated open end to the rear and is recessed about... 

Place 2 toy caps over small hole in end cap. Be sure metal strap will hit caps when it is released. 

Toy caps are commonly made from red phosphorus and potassium chlorate, a combination which is the most sensitive, dan-... 

It would be ideal to reject this material from fireworks, but it is quite difficult even at present, because no other oxidizer can surpass potassium chlorate in burning speed, in ease of ignition or in noise making, using the smallest amount of composition. The match head composition cannot be made without it it is also absolutely necessary for some dye smoke, small crackers and various kinds of toy caps. However these articles tend to become a source of explosion, and we must treat potassium chlorate compositions with respect and caution. 

Amorce is a French word that means cap, primer, detonator, or fuse, terms that differ from the English usage of amorce used to describe the toy caps used in toy pistols or thrown down sharply in play. They contain extremely small quantities (around Img) of shock sensitive explosive mixtures of potassium chlorate and arsenic monosulphide or silver fulminate. Trick matches are toys that are extremely difficult to blow out.

Although primary explosives are by far the most dangerous energetic materials because they axe so easy to initiate, they do have applications in other areas. For example, most matches make use of friction-sensitive compounds in the match bead. Also, many toy caps, toy torpedoes, and similar devices used for generating noise make use of pri mary explosives To some extent, one might say that these applications of primaiy explosives existed before they were used in the explosives industry. It should be noted, however, that in all of these nonindustrial applications, the pri-xoaxy explosive is used in very small amounts.
