PRACTICAL PROBLEMS

• A fire is considered fully developed when the growth stage has reached its maximum and all combustible materials have been ignited, making it the hottest phase of a fire and the most dangerous for anyone trapped within.
• During the decay stage, there is a danger of non-flaming combustibles potentially starting a new fire if not fully extinguished, and a danger of a backdraft when oxygen is reintroduced to a volatile, confined space.
• A "flashcard>
• Decay is usually the longest stage of a fire, characterized by a significant decrease in oxygen or fuel, ending the fire.
• Fire safety design begins with the preservation of the structure and its contents against fire damage or destruction, which is a serious concern to owners and others having a financial interest in property.
• A deadly "flashcard>
• The aim in fire safety design is to prevent fire, safeguard the lives of occupants and firefighters, reduce damage to the building, its contents, and surrounding buildings.
• A high-rise building is defined in terms of fire protection as too tall to be completely accessible to fire-fighting equipment from the ground, too tall to make complete evacuation of occupants feasible, and tall enough to make possible chimney or stack effects for air and smoke flow.
• Factors affecting the growth stage of a fire include the location of the fire, combustible materials near it, ceiling height, and potential for "thermal layering".
• Fire safety design is affected by the permitted building density in the locality, the flammability of the building and its expected contents, and the materials and equipment that must be considered.
• Materials and equipment that must be considered in fire safety design include fire resistance of the selected structural type and material and the contents of the building, limitations of volumes within fire-resistant barriers in otherwise vulnerable buildings, precautions against perforations of approved and required barriers, exits and fire tower stairs, protection against fires caused by electrical systems, protection against fires caused by lightning, detection and alarm system, standpipe and hose systems within and near buildings, automatic sprinkler systems, automatic smoke and heat ven
• Cutters are surfaces located close to the fulcrum and are used for cutting wire and cables.
• A tension wrench is the “key” component in lockpicking and can be found in a wide range of designs.
• A spoke wrench has a slot that fits around the spoke and a drive head that fits around the nipple nut.
• A stubby wrench, referred to as a short body wrench in polite circles, is a shorter version of a combination wrench, allowing it to fit into more confined spaces.
• A strap wrench, most commonly seen in use for oil filter changing, has a rubber, fabric, or metal band or chain that loops through a handle.
• Jaws, or nose, are the working end of pliers and are used primarily for gripping.
• Combination pliers have jaws which also contain cutters and/or pipe grips.
• The fulcrum, or pivot point, is where the handles and jaws connect and serves to create enough force for the jaws to perform their duty.
• Crimping pliers, also known as crimping tools, have the fulcrum at the far end and are used similarly to a nutcracker.
• Pipe grips are a rounded opening in the jaws, designed to do what the name implies, and are very useful for gripping round objects.
• Handles are the part you hold and can be straight or curved, with a bare metal or plastic coated surface.
• A spud wrench, another tool that has fallen out of common use, had a spike on the opposing end which was used to line up the holes on pipes.
• Wires are fed into the jack of the jaw first, then the connector, and squeezing the handles will break through the plastic coating and cause the two sections to deform (or crimp) in such a way that they stick together and allow data to pass through.
• Parts of pliers include cutters, the fulcrum or pivot point, handles, and jaws or nose.
• A torx key, sometimes referred to as a star-headed key, is designed to fit into the star-shaped heads of certain bolts and screws.

• Slotted, also known as flat blade, flat head, or straight, is the most popular of all screwdriver types, with a chisel-shaped blade which spans the width of a screw’s head, often doubling as a chisel in emergencies, and can also be used on a Phillips head screw.
• Torx, also known as Torx plus version or Torx security version, was originally used for security functions, but has become popular in commercial fields due to their efficiency and the fact that consumers have a more difficult time taking apart an appliance with Torx screws.
• Toolmaker’s Hammer has a ball pein and rounded head and is used for performing delicate work in a machine shop.
• Phillips, also known as cross head, is used in almost everything from furniture to appliances, with an angled tip that allows a screwdriver to fit deeper into the screw head and there’s no risk of the blade sliding out sideways.
• Tinner’s Hammer has a square head and sharpened cross pein and is used for completing seams and setting a rolled edge in metalwork.
• Welding Hammer has a round chisel at one end and a vertical pein on the other, with a handle that has an unusual spiral design to dissipate heat and is used to remove slag from welding points once the weld bead has had a chance to cool.
• Allen wrenches are most commonly used in bike maintenance, but have become increasingly popular with furniture companies such as Ikea and with some appliance manufacturers.
• A specialized security version of the hex key is used in high-risk fields, such as prison maintenance.
• Hex, also known as Allen wrench or hex key, is a type of screwdriver that lacks a handle or tip, resembling a small, six-sided metal shank bent into an L-shape and lacking a head, often included at no cost with packaged furniture.
• Trim Hammer has a straight claw and is smaller than normal claw hammers, sometimes referred to as a finish hammer, with a smooth face for driving trim nails without damaging the surrounding surface.
• Soft Jaw Pliers, used for plumbing and scuba diving equipment, have padded jaws to prevent scratches on chrome and other soft metals or exposed surfaces.
• Framing Hammer, closely resembling a claw hammer, has a straight claw and waffled head, and is named after its primary function, which is assembling house frames.
• Split Ring Pliers, resembling a stubby version of needle nose or chain nose pliers, have a hooked tip on the lower jaw that acts as a wedge, splitting coiled rings apart.
