The inspection of your home is not as intrusive as it sounds. We will visit your home, sit down and talk to you about many fire safety issues in your home, covering areas such as electrical safety, smoking and the use of electric blankets. We will then, with your permission, look at the various rooms within your home paying particular attention to areas such as overloaded plug sockets or wires trapped under carpets. We will also ensure that doors shut correctly and advise you of anything that needs addressing to make your home a safer one. You are welcome to ask any questions that you feel you need answering in respect of your home safety. We will also run through an escape plan if you do not already have one. You may qualify for free smoke alarms to be fitted within your home. We will carry this out completely free of charge and can fit them in a matter of minutes, ensuring you are safer from the moment we leave.
During commercial manufacturing, the amount of chemical composition in a building at any one time should be kept as low as possible. The workers should wear non-sparking or conductive shoes. Floors should be conductive as outlined in the National Fire Protection Agency (NFPA) standard #99. Cotton clothing should be worn, and all metal machinery and moving parts should be well grounded electrically, to bleed off static electricity before it can build up a dangerous charge. No matches should be allowed in the manufacturing area. Change houses or areas where smoking is permitted will help keep the dangers of smoking under control. Safety training and periodic scheduled safety review meetings with employees are required by OSHA. Close supervision during work is essential to safety.

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.
Low voltage currents can do no harm, while high can lead to people do not follow the rules of electrical safety, they undergo a great risk to get into es caused by electrocution as well as fires in electrical systems occur primarily due to ignorance of basic rules of electrical safety and only then â due to non-compliance with these ical safety in terms of country living differs from electrical safety in urban environments.
With more and more electrical firing of display fireworks taking place each year, the operators must recognize and practice a new set of safety guidelines. Without forming new electrical safety habit awareness or by taking squib safety for granted, accidents will occur given the right conditions. Many will agree, including myself, that electrical display firing is far less hazardous than hand firing. Yet we must be aware of and respect the subtle dangers lurking in the shadows of ignorance and avoid complacency in order to seek out and enjoy safety perfection. - WO
Extensive studies on electrical bridge wires for explosives initiation have been undertaken for may years at the Franklin Institute and at companies such as Atlas Explosives, Dupont and Ireco, Inc. where this writer is employed as a staff Electrical Engineer. Resistive bridge wires of varying length, diameter, alloy and hence resistive and thermal value are used in virtually thousands of devices of differing design. Devices such as: squibs (a catch-all broad and vague term in the industry), igniters, explosive bolts, detonators of many different sizes and shapes, safe & arm military devices and blasting caps are to name but a few. Electric igniters (or squibs as we fireworks people call them) are electrically very similar to the electric circuit in blasting caps. In fact, the ICI squib so commonly used by professional display operators, is the exact same igniter manufactured and used in Atlas blasting caps. (Atlas is a division of Gulf Explosives, Inc.). The electrical studies made on bridge wire initiated devices involve, for example, environmental studies of performance under extreme conditions. These tests include, but are not limited to, freezing, baking, pressurized submergence in salt water, mechanical shock and vibration to many g's, static electricity discharges, and RF energy excitation of finished devices. Parameter measurements include studies for changes in: bridge wire resistance, elapsed time from electrical initiation to detonation, fusion time (initiation to bridge wire melt-down time), initiation energy requirements (all-fire and no-fire current limits), explosive power output of the device, and high voltage static electricity sensitivity.
The all-fire and no-fire current limits, RF energy excitation effects and static electricity effects on fireworks squibs at ambient environmental conditions is easily recognized as a safety concern. The all-fire current is defined as the level of applied current at which 100% ignition is guaranteed by the manufacturer. Generally, this figure is 1.0 amps flowing through the bridge wire after allowing for wire line losses. The no-fire current limit is somewhat more complicated and vague as environmental conditions have a great effect on the value. Conditions such as temperature, ground leakage current , RF energy excitation, the presence of static charges, etc. adversely affect the value of this limit. However, no-fire current limit is generally defined as the minimum applied current at which a squib is guaranteed to not fire under lab conditions. This value is generally given at 0.1 amps (100 milliamps). For field circuit testing, the Institute of Makers of Explosives (IME) recommends the test current for measuring the resistance of field wiring by the user be limited to under 0.01 amps (10 milliamps).
