Fire safety essay - Research Writing Aid & High Quality …
PRO FAX will feature safety articles as in the past but will now also include expanded coverage of business events with the emphasis on professionalism. I am especially looking forward to writing about subjects such as professional display operator career development, how-to articles, the financial analysis of a display, inside tips of how to maximize profits, and how to reduce liability risks. I hope to stimulate controversy in some areas and maybe report some of the reader reactions to hot topics! I would also like to impress readers with the incredible "would you believe...." type features and I invite readers to write to me with details of incredible experiences involving fireworks, either pro or amateur. You can write to me at:

If you get stuck developing these claims, try to think of reasons why your thesis is true. Each claim should be a reason why the reader should believe your paper’s main idea. For example, perhaps you’re writing an essay about whether people should drink soy milk instead of cow’s milk. Your "reasons" for this might include health benefits, environmental benefits, cost-effectiveness, and safety, so you would focus one paragraph on each of these topics.
A shell that breaks low causing colors to fall burning to the ground, or other effects such as reports to go off on the ground, is usually caused by insufficient lift pressure in the mortar from which the shell was fired. The most common reason (on hand fired displays) is, the operator placed the shell in the wrong size mortar pipe. For example, a 4" shell cannot be put in a 3" mortar but it can be placed in a 5" mortar by mistake. When this happens, the propellant lift charge gas pressure escapes around the outside of the shell instead of concentrating its driving energy underneath the shell. The result is the shell "puffs" out of the mortar, goes about 50 feet into the air, arches over and then falls toward the ground. The shell will burst low on its way to the ground scattering burning stars towards the ground. If the shell was a color with report or a multibreak shell, the remaining effects will continue to go off on the ground. If this should ever happen, it is imperative that all shell "ready" boxes or other such containers of live shells, be kept tightly closed or covered. Anyone on the crew who first notices this problem must quickly holler out and warn the others. The first sign of this type of problem-error will be the sound of the mortar at discharge. A "whoosh" or "foomp" sound should be an alarm signal. The normal discharge sound is a good cracking report - "thump!", which may sometimes ring the steel mortar pipe. Experience will teach the new operator the proper sound, and a low break will definitely sound different and grab attention. Other causes of a low break shell are a cracked mortar pipe, or too little lift charge when a shell was manufactured. These causes are very rare, however, and even a shell with reduced lift charge, when fired from the proper size mortar, will still achieve a fairly safe altitude when it bursts. If a mortar is cracked, or the bottom blown open, all shells fired from that particular mortar will be low breaks. This happens only when shells are repeatedly fired from an aluminum or heavy gage PVC plastic mortar with a wood bottom plug. It has never happened with a steel (welded bottom) mortar, except when shells detonate within. If a steel pipe blows its bottom, it suddenly won't be there anymore with only a crater left behind. Aluminum or plastic mortars must never be used as battery mortars, (those reloaded during a hand fired display;). Steel mortars have been know to develop cracks only if they overheat while taking a constant pressure pounding from repeated firings. This is why two 3" and two 4" steel battery mortars should be issued on every hand fired display. By firing alternately between the two mortars of each size, overheating is avoided. The larger 5" and 6" mortars can absorb and dissipate much more heat due to their shear mass and surface area. Also there are fewer 5" and 6" shells in any display compared to the quantity of 3 and 4" shells, which comprise the bulk quantity of display shells.
