Terms Associated with Plumbing Safety
Click on each term to find out more:
Apparatus
One tool, which combines a variety of functions, to perform a particular job.

Asbestos
A fibrous, fire-resistant substance used in pipe insulation, shingles, wallboards, floor coverings, and certain types of insulation. (This material is now banned by government regulation as a health hazard.)

Atmospheric Hazard
A potential danger in the air or a condition for poor air quality.

Benching
A method of protecting workers from cave-ins by excavating the sides of an excavation to form one or a series of horizontal levels or steps, usually with vertical or near-vertical surface between levels.

Bladed Tools
Tools that have a sharp edge. Bladed tools include saws, knives, scissors, tin snips, and wire cutters.

Combustible
Air or materials that can explode and cause a fire.

Confined Space
A space that, by design and/or configuration, has limited openings for entry and exit, has unfavorable natural ventilation, may contain or produce hazardous substances, and is not intended for continuous employee occupancy.

Decibels (dB)
A measure of sound intensity or loudness. The higher the decibel level, the louder and more potentially damaging the sound is.

Electrically Powered Tools
Tools that use electrical current to operate.

Energy-Isolating Device
Any mechanical device that physically prevents the transmission or release of energy. These can include manually operated electrical circuit breakers, disconnect switches, line valves, and blocks.

Energy Source
Any source of electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other energy.

Gassy Operations
Working condition in which one or more of the following conditions exist: higher than minimum levels of methane or explosive gases are present; a gas ignition has previously occurred there; or the area is connected to an underground area designated a gassy operation.

Guards
Devices that protect tools operators from dangerous moving parts, such as blades, gears, and pulleys.

Guy Wires
Ropes, chain, cables, or rods attached to something as a brace or guide.

Hazard Communication (HazCom) Standards
A federal OSHA regulation requiring employers to educate and inform workers about chemical hazards on the job site.

Hypothermia
A life-threatening condition caused by exposure to very cold temperature.

Impact Tools
Tools that strike against something or must be struck in order to accomplish a task. They include hammers, chisels, and taps.

Liquid-Fuel Tools
Tools that use a liquid fuel, such as gasoline or liquid propane, to operate.

Lockout
The placement of a lockout device on an energy-isolating device, in accordance with an established procedure. This is done to ensure that the energy-isolating device and the equipment being controlled cannot be operated until the lockout device is removed.

Lockout Device
Any device that uses positive means such as a lock to hold an energy-isolating device in a safe position, thereby preventing the energizing of machinery or equipment.

Lockout / Tagout Procedure
A process for identifying hazardous equipment, locking it so that no worker can use it until it is certified for safe use, and placing a tag on the equipment that describes the problem and warns against use.

MSDS
Material safety data sheet (MSDS) is a document that must accompany any hazardous material. The MSDS identifies the material and gives the exposure limit, the physical and chemical characteristics, the kind of hazard it presents, precautions for safe handling and use, and specific control measure.

NFPA Diamond Warning
A four-color diamond label placed on containers or doors to alert people to specific safety hazards in a product room, or building.

Nonpermit-Required Confined Space
A confined workspace free of any atmospheric, physical, electric, and mechanical hazards that can cause injury or death.
