Title 34: Flammable & Combustible Liquids Regulations Flashcards
What is the definition of “inflammable”? (Flammable & Combustible Liquids regulations, Title 34, Section 14.1)
Flammable.
If end failure of a horizontal tank may endanger adjacent property, how must the tank be positioned? (Flammable & Combustible Liquids regulations, Title 34, Section 14a.1 (b))
If end failure of horizontal tanks may expose property, the tank shall be placed with the longitudinal axis parallel to the more severe exposure.
What is the minimum shell to shell distance allowed for tanks storing flammable or combustible liquids? (Flammable & Combustible Liquids regulations, Title 34, Section 14a.2 (a))
The distance from shell to shell between flammable or combustible liquid storage tanks shall not be less than three feet.
What is the minimum distance allowed between tanks storing unstable liquids? (Flammable & Combustible Liquids regulations, Title 34, Section 14a.2 (d))
The distance between tanks storing unstable liquids shall not be less than 1/2 the sum of their diameters.
What effect does heating have on the volatility of a liquid? (Flammable & Combustible Liquids regulations, Title 34, Section 14.6(c))
The volatility of liquids is increased when heated to temperatures equal to or higher than their flash points.
What factors determine the required venting capacity of a tank? (Flammable & Combustible Liquids regulations, Title 34, Section 14a.25 (c))
The required venting capacity depends upon the filling or withdrawal rate, whichever is greater, and the vent-line length.
How shall tanks and piping be tested prior to being placed in use? (Flammable & Combustible Liquids regulations, Title 34, Section 14a.26(a))
Tanks shall be tested hydrostatically, by air pressure, or by other methods approved by the fire marshal, at not less than 3 psig nor more than 5 psig.
The area surrounding a tank or group of tanks may be provided with a drainage system to prevent accidental discharge of liquid from endangering adjoining property of reaching waterways. In what areas is this drainage system NOT allowed to discharge? (Flammable & Combustible Liquids regulations, Title 34, Section 14a.6 (b)(3))
The drainage system, including automatic drainage pumps, shall not discharge to adjoining property, natural water courses, public sewers, or public drains, nor discharge in any manner that would constitute a hazard.
What should be the capacity of a diked area surrounding tanks with fixed roofs containing liquids with boil over characteristics? (Flammable & Combustible Liquids regulations, Title 34, Section 14a.6 (c)(2))
For tanks with fixed roofs containing crude petroleum with boilover characteristics, the diked area shall be designed to contain the volume of liquid that can be released from all tanks served by the enclosure.
When earthen walls are used to construct a dike, what is the minimum width of the top of the dike when the dike wall is three feet or more in height? (Flammable & Combustible Liquids regulations, Title 34, Section 14a.6 (c)(3))
Earthen walls 3 feet or more in height shall have a flat section at the top not less than 2 feet wide.
What is the maximum allowable height of a dike wall above interior grade? (Flammable & Combustible Liquids regulations, Title 34, Section 14a.6 (c)(3))
Dike walls shall be restricted to a maximum height of 6 feet above interior grade.
Can a building wall be used as part of a dike wall? (Flammable & Combustible Liquids regulations, Title 34, Section 14a.6 (c)(3))
The use of building walls as part of dike walls is prohibited.
Where vent piping for tanks storing class I liquids is located adjacent to buildings or public ways, what is the minimum height above adjacent ground level that vapors may be discharged? (Flammable & Combustible Liquids regulations, Title 34, Section 14a.8 (c)(1))
Where vent piping for tanks storing class I liquids is adjacent to buildings or public ways, the vent piping shall be located so that the vapors are released at a safe point away from buildings and not less than 12 feet above the adjacent ground level. In order to aid their dispersion, vapors shall be discharged upward so that flammable vapors will not be trapped by eaves or other obstructions.
What is the minimum distance required between vent openings and building openings? (Flammable & Combustible Liquids regulations, Title 34, Section 14a.8 (c)(1))
Where vent piping for tanks storing class I liquids is adjacent to buildings or public ways, the vent piping shall be located so that the vapors are released at a safe point away from buildings and not less than 12 feet above the adjacent ground level. In order to aid their dispersion, vapors shall be at least 5 feet from building openings.
How far above maximum flood stage must the top of a vertical tank extend? (Flammable & Combustible Liquids regulations, Title 34, Section 14a.212 (a))
Each vertical tank shall be located so that its top extends above the maximum flood stage by at least 30% of its allowable storage capacity.
