On Tuesday, September 21, 2010, secretary of transportation, Ray Lahood, stated that “any time you take your eyes off the road, your hands off the wheel, and your mind off your primary task: driving safely”, distraction occurs, increasing your risk of crashing....
In part one of this continuing series, we can easily agree the dud aerial shell is a common safety concern of all shell makers, pros and amateurs alike. In broad definition of the dud, it was said we can place the phenomenon in four categories: (1) the flower pot shell, (2) time delay fuse ignition failure, (3) time delay fuse failure after ignition, and (4) internal shell ignition failure after fuse burn through.

In the third category, human carelessness is where most fireworks accidents can be attributed. "The responsible person knew better, but took a chance anyway," or "he just didn't know any better." The number one rule everyone making fireworks should adopt is: "If you don't know, you don't do!" At least until you know all the facts about what it is you intend to do. I firmly believe one of the biggest contributing factors for this industry's poor safety record (in the U. S. A.) is the prevalent attitude of prideful secrecy among professionals, and the ignorant curiosity of man. Don't do unless you know. For example: you have just mixed a 5 ounce batch of a new formula using chemicals you know nothing about. The formula works. Should you go ahead with making a 20 pound batch? Have you done friction sensitivity tests? Impact tests? Chemical compatibility research? Toxicity research? Or have you only decided a 5 ounce sample worked good when ignited? A lot of unknown hazards could exist that are difficult or impossible to control or need special handling consideration in larger batches, especially when wet mixing for stars.

Almost all the ingredients used in fireworks compositions are used as finely divided powders, which greatly increases their surface area in a given volume and/or density. For example, a charcoal dust cloud in air explodes violently when ignited. Therefore, all finely divided mixtures of materials should be handled with care. This is especially important with finely divided metals, which are hard enough to cause friction ignition. Finely divided metals present a hazard to violent explosion when ignited, and are susceptible to ignition by static electricity more easily than other mixtures due to their conductivity. Steel tools must be avoided in grinding, mixing, charging, pressing, tamping, ramming, or other similar loading operations. Steel tools create sparks when struck. The almost as hard bronze, may be used for certain purposes, but the much softer brass and lead are safer. Wood and aluminum tools, and mallets made of rawhide are also non-sparking safe.

There are three types of road safety signs – mandatory, cautionary and informatory that enlightens us about the condition of a road ahead and instructs us what we need to do at relevant junctions and crossroads. By being conscious of these signs, we can affirm of not running into problems.
