Safety margin definition

Safety margin means the amount by which the total projected emissions from all sources of a given pollutant are less than the total emissions that would satisfy the applicable requirement for reasonable further progress, attainment, or maintenance.

Safety margin means an accounting technique used by WSFR to determine the age of funds using the “first in, first out” (FIFO) method. This allows WSFR to use the most liberal interpretation of assigning an age to any funds that become available from a prior year apportionment. Safety Margins are only established at the end of the Federal Fiscal Year (FFY). The safety margin determines if de‐obligated (unspent) funds have another year of funding availability to be obligated to future grants. For these grant programs, de‐obligated grant funds must “pass through the safety margin” to be recovered and returned to the State grant program account. De‐obligated grant funds that do not pass through the safety margin will revert to the Service to be used in accordance with grant program rules. Grant funds obligated and de‐obligated during the same FFY are returned to the State grant program account and do not pass through the safety margin. WSFR Training has developed a safety margin training video to assist in understanding the safety margin process.

Safety margin means the value expressing the difference between the safety limit and the acceptance criterion established using the conservative approach,

• The D-ring height needs to be adjusted for very tall workers, and for shorter workers as well.■ Safety margin: An additional distance (typically a minimum of 2 feet) to ensure that there is enough clearance between the worker and the lower level after a fall.The total fall clearance distance can be calculated by adding all of these values together.

More Definitions of Safety margin

Safety margin means adjustments made to compensate for uncertainties in the methods and assumptions used to evaluate the alternative design, e.g. in the determination of performance criteria or in the engineering models used to assess the consequences of a casualty.

Safety margin means the pressure value that is equal to 10 pounds per square inch gauge (psig) or 10 percent of the test pressure, whichever is greater. The safety margin value is used to determine the maximum allowable operating pressure of an underground storage cavern system.
