Practical Problems Flashcards
Used to fasten or hold material or device to prevent movement, rotation, or displacement at the point of application
ANCHOR
An assembly or bracket device used to resist twisting or to restrain a piping run in the axial direction
AXIAL BRACE
An appliance or device used as a hanger or support for pipe that provides for vertical adjustment. It is also used to connect pipe to a hanger assembly.
BAND OR STRAP HANGER
A preformed appliance or assembly consisting of various components that, depending on its location, is used to hold and/or restrain a piping system from horizontal, vertical, and lateral forces
BRACE, BRACE ASSMEBLY
A preformed support or fastener, usually constructed in a cantilevered manner, with or without additional diagonal structural members for load stability and designed to withstand a gravity load and horizontal and vertical forces.
BRACKET
A mechanical device used to connect, as a hanger or support, or used to hold part of a piping system to structural beam element
CLAMP
A connector or device or metal shackle with drilled ends to receive a pin or bolt and that is used for attaching or suspending parts
CLEVIS
A device that is** suspended from a structure and used to carry or support a load**
HANGER
Round steel bar, normally threaded, used to connect components for hangers and supports
HANGER ROD
What is the rod size for pipe and tube size 1/2-4”?
3/8”
What is the rod size for pipe and tube size 5”-8”?
1/2”
What is the rod size for pipe and tube size 10-12”?
5/8”
An opening, conduit, or channel that is cast in place within concrete structural elements and that provides for the passing through of pipe
PIPE SLEEVE
Appliances and devices, including chain, rope, and cable, used to erect, support, and manipulate
RIGGING
An attachment appliance used to connect a pipe directly to a structural element
STRAP
A pipe hanger consisting of parallel vertical rods connected at their lower ends by a horizontal member that is suspended from a structural element.
TRAPEZE HANGER
OSHA
Occupational Safety and Health Administration
This administration ensures safety and healthful working conditions for workers by setting and enforcing standards and by providing training, outreach, education, and assitance
OSHA
Hazard caused by falls, falling objects, frostbite, heat or cold stress; also included noise, radiation, and pressure
PHYSICAL HAZARDS
Hazards from exposure to a virus or bacterial infection
BIOLOGICAL HAZARDS
Hazard resulting from the inhalation or contact with a chemical toxic substance
CHEMICAL HAZARDS
Hazard referring to mental health and personal well-being; example , work shift arrangements, work load, harassment, discrimination
PSYCHOSOCIAL/PSYCHOLOGICAL HAZARD
Hazards relating to efficiency and comfort in the workplace; example, a poor workstation setup in an office
ERGONOMIC HAZARDS
Also known as “flammable limits”
EXPLOSIVE LIMITS
Refers to the concentration of a gas or vapor in the air which will result in an explosion - if an ignition source is present
EXPLOSIVE LIMITS
What is the minimum safe level of oxygen in the confined space?
19.5%
What is the maximum safe level of oxygen in a confined space?
23.5%
The lowest concentration of a gas or vapor in the air which will burn or explode if ignited
LOWER EXPLOSIVE LIMIT (LEL)
The highest concentration of gas or vapor which will burn or explode if ignited
UPPER EXPLOSIVE LIMIT
The average exposure to any hazardous gas in the workplace based on an eight-hour workday or 40-hr work week
TIME WEIGHTED AVERAGE (TWA)
The maximum amount one may be exposed to without experiencing significant adverse health effects over said period
TIME WEIGHTED AVERAGE (TWA)
