(i)
“Class IIIB liquid” means a combustible liquid that has a flash point at above 200°F (93° C).
(j)
“Combustible liquid” means any liquid that has a closed-cup flashpoint at or above 100° F (37.8°C), as determined by the test procedure and apparatus specified in Section 4.4 of NFPA 30, Flammable and Combustible Liquids Code.

(o)
“Flammable gas” means a material that is a gas at 68° F (20° C) or less at an absolute pressure of 14.7 psi (101.3 kPa), that is ignitable at an absolute pressure of 14.7 psi (101.3 kPa), when in a mixture of 13 percent or less by volume with air, or that has a flammable range at an absolute pressure of 14.7 psi (101.3 kPa) with air of at least 12 percent, regardless of the lower limit.
(p)
“Flammable liquid” means any liquid that has a closed-cup flashpoint below 100° F (37.8°C), as determined by the test procedure and apparatus specified in Section 4.4 of NFPA 30, Flammable and Combustible Liquids Code and a REID vapor pressure that does not exceed an absolute pressure of 40 psi (276 kPa) at 100° F (37.8°C), as determined by ASTM D 323, Standard Test Method for Vapor Pressure of Petroleum Products (Reid Method).
(q)
“Flammable solid” means a solid, other than a substance defined as a blasting agent or explosive, that is liable to cause fire resulting from friction or retained heat from manufacture, that has an ignition temperature below 212°F (100° C) or that burns so vigorously or persistently when ignited that it creates a serious hazard.
(r)
“Flash point” means the minimum temperature at which sufficient vapor is given off a liquid to form an ignitable mixture with air, near the surface of the liquid or within the vessel used, as determined by the appropriate test procedure and apparatus specified in Section 4.4 of NFPA 30, Flammable and Combustible Liquids Code.
(s)
“Gallon” means the U.S. standard gallon.
(t)
“Hot work” includes any open flame, electrical equipment which may cause sparks, including welding, cutting or spark producing operation.

“Police chief” means the Everett police chief or his designee.
(z)
“Psi” means pound per square inch and is the pressure resulting from a force of 1 pound-force applied to an area of 1 square inch.
(aa)
“Psia” means pounds per square inch absolute and is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around 14.7 psi, this will be added to any pressure reading made in air at sea level.
