Dross
Part of the electrical distribution system that brings electricity from the streets source, power poles and transformers, through the service lines to the electrical meter mounted on the outside of the building into the panel inside the building. The panel houses the circuits that distribute electricity throughout the structure.
Electrical distribution panel
Any man-made cut, cavity, trench, or depression in earths surface, formed by removing earth. It can be made for anything from basements to highways.

Extension ladder
Capable of easily igniting and rapidly burning; used to describe the fuel with the flash point below 100°F
Flammable
A sudden bright light associated with starting up welding torch.
Flash
A welding flame that flares up and charge the hose at or near the torch connection. It is caused by improperly mixed fuel.
Flashback
The damage that can be done to our eyes after even brief exposure to ultraviolet light from the arc welding. A flashburn requires medical attention.
Flashburn
Protective equipment worn during welding operations.
Flash goggles
The temperature at which fuel gives off enough gases (vapors) to burn.
Flashpoint
A unit of measurement of the intensity of light falling on a surface, equal to 1 lumen per square foot and originally defined with reference to a standardized candle burning at 1 foot from a given surface.
Foot candle
The conducting connection between electrical equipment or an electrical circuit and the earth.
Ground
A device that interrupts and de-energizes an electrical circuit to protect a person from electrocution.
Ground fault circuit interrupt (GFCI)
Enclosed, fenced, covered, or otherwise protected by barriers, rails, covers, or platforms to prevent dangerous contact.
Guarded
A line attached to a tool or object so worker can pull it up after climbing a ladder or scaffolding.
Hand line
The occupational safety and health administration standard that requires contractors to educate employees about hazardous chemicals on the job site and how to work with them safely.
Hazard communication standard (HazCom)
A short section of rope or strap, one end of which is attached to a worker’s safety harness and the other to a strong anchor point above the work area.
Lanyard
A formal procedure for taking equipment out of service ensuring that it cannot be operated until a qualified person has removed the lock out or tag out device, such as a lock or warning tag.
Lock out/tag out
The organization of a company’s management, including reporting procedures, supervisory responsibilities, and administration.
Management system
A document that must accompany any hazardous substance. MSDS identifies the substance and gives the exposure limits, the physical and chemical characteristics, the kind of hazard it presents, precautions for safe handling and use, and specific control measures.
Material safety data sheet (MSDS)
Steepest incline of an excavation face that is acceptable for the most favorable site conditions as protection against cave-ins, expressed as the ratio of horizontal distance to vertical rise.
Maximum allowable slope
The total weight of all people, equipment, tools, materials, and loads that a ladder can hold at one time.
Maximum intended load
Mid-level, horizontal board required on all open sides of scaffolding and platforms that are more than 14 inches from the face of the structure and more than 10 feet above the ground. It is placed halfway between the toeboard in the top rail.
Mid-rail
An agency of the US Department of labor. Also refers to the occupational safety and health act of 1970, a law that applies to more than 111 Million workers and 7 million job sites in the country.
Occupational safety and health administration (OSHA)
A confined space that it has been evaluated and found to have an actual or potential hazards, such as a toxic atmosphere or other serious safety or health hazard. Workers need written authorization to enter a permit required confined space.
Permit required confined space
Equipment or clothing design to prevent or reduce injuries.
Personal protective equipment (PPE)
Having pieces of material two or more inches thick and six or more inches wide used as flooring, decking or scaffolding.
Planked
Work done near a hazard but not actually in contact with it.
Proximity work
A person who, by possession of a recognize degree, Certificate, or professional standing, or by extensive knowledge, training, and experience, has demonstrated the ability to solve or prevent problems relating to a certain subject, work, or project.
Qualified person
A device that fights clean, filtered air for breathing, no matter what is in the surrounding air.
Respirator
The culture created when the whole company sees the value of a safe work environment.
Safety culture
And elevated platform for workers and materials.
Scaffold
