NFPA 704

A system used to visually identify potential hazards on fixed facilities, such as refineries, storage facilities, industrial sites, and retail stores. It can also be displayed on some non-bulk containers for certain materials. This is a voluntary standard, but some local building and fire codes require this marking to be displayed.

Flux-cored Arc Welding

A type of MIG welding. A wire is passed through a gun that creates an arc to a grounded workpiece, creating a weld puddle, welding the base materials together. Does not use a shielding gas; instead, the wire contains a flux in its core that burns and creates gas as the process continues. As the weld cools, it will have a coating on the outside that can be chipped away.

Flaming Front

AKA: the fire front, is the part of a fire within which continuous flaming combustion is taking place. Most of the time, this is the leading edge of the fire perimeter. However, in surface fires, the flaming front may be mainly smoldering combustion. Behind this zone, combustion is primarily glowing or involves the burning out of larger fuels (fuels greater than about 3 in. in diameter). Light fuels typically have a shallow front, whereas heavy fuels have a deeper front.

OSHA 1910.1200

Collapse that occurs after the initial collapse of a structure secondary to weather conditions, earthquakes, or movement of internal structures.

Shoring

Construction materials such as timber, screw jacks, hydraulic jacks, and/or pneumatic jacks, that are used in the process of supporting a structure in order to prevent collapse.

Smoldering Fire

Fire is one that burns without a flame and is barely spreading.

Running Fire

Fire that spreads rapidly with a well-defined head.

Pyrophoric Gas

Gas that ignites in air without the introduction of an ignition source. Silane is a common example, used in manufacturing electronics.

Tempered Glass

Glass that has been chemically or thermally treated to increase its strength and become more break-resistant than regular glass. Safer than regular glass because it crumbles into chunks rather than jagged shards.

Corrosive Gas

Hydrogen chloride and hydrogen fluoride are examples of:

Often called wire welding. It uses a filler material in the form of a wire, which is fed through a gun. This process uses a welding machine that generates an electrical current that travels through a filler wire. When the current gets close to the grounded workpiece, it arcs, causing the filler wire and the base materials to melt and join together. This process uses a mixture of carbon dioxide and argon gases.

Spot Fire

Small fires burning beyond the main fire boundary. As gases rise from a fire into the convection column, sparks, embers, and burning twigs are carried aloft. These result, as hot and burning items fall back to the ground, or are blown across a fire line by winds. These can also result when embers or burning fuels roll downhill across the fire line into unburned fuels beyond the main fire.

AHJ

This is the jurisdiction in which has the authority to enforce the fire codes and ordinances in which has been adopted.

Radiation

This is the transfer of heat from the radiant waves being given off from the object or material burning.

29 CFR 1910.430

Backing Fire

A fire that moves away from the head, downhill, or against the wind. Also called a heel fire.

Block and Tackle

A system of two or more pulleys with a rope or cable threaded between them used to lift or pull heavy loads.

Gas Tungsten Arc Welding / Tungsten Inert Gas Welding

Also known as Heliarc welding. A tungsten electrode is housed within a handle called a torch. The electrode is not consumed during welding. Welding current passes through the tungsten and arcs to the grounded workpiece, creating a molten puddle. Filler material is added with a filler rod of the same material being welded. This is one of the strongest welds possible. Used when a precise, high-strength, visually appealing weld is desired. It creates the most intense light of any process. Uses a shielding gas of argon or helium.

Way Bill

Also known as a consist. Located in the locomotive of the train.

Slopover

Also known as breakover, occurs when fire crosses a control line or natural barrier intended to contain the fire. Spot fires differ mainly in their location relative to the control line. Occurs immediately across and adjacent to the control line, while spot fires occur some distance from the control line.

Shielded Metal Arc Welding

Also known as stick welding. It does not require a shielding gas and equipment is relatively inexpensive. An electrical current is passed through the electrode (stick) to the grounded workpiece. The arc created melts the base metal and the electrode, creating a molten puddle. The base material combines with the filler material, creating a weld. This process has the potential for electrocution, if a person touches the electrode holder or electrode, and the grounded workpiece at the same time.

Black
