NFPA-30 9.13.3 Curbs, scuppers, special drains, or other suitable means shall be provided to prevent the flow of liquids under emergency conditions into adjacent building areas.
IFC-2704.2.2.3 (2009) Secondary containment for indoor storage areas shall be designed to contain a spill from the largest vessel plus the design flow volume of fire-protection water calculated to discharge from the fire-extinguishing system over the minimum required system design area or area of the room… for a period of 20 minutes.
OSHA 1910.106 (e) (3) (iv) (a) Emergency drainage systems shall be provided to direct flammable or combustible liquid leakage and fire protection water to a safe location. This may require curbs, scuppers, or special drainage systems to control the spread of fire.
OSHA 1910.106 (d) (4) (i) Openings to other rooms or buildings shall be provided with non-combustible liquid-tight raised sills or ramps at least 4” in height.
Canadian Environmental Protection Act, 1999, S.C. 1999, c. 33 (CEPA), Environmental Emergency Regulations SOR/2003-307 Where there occurs or is a likelihood of a release into the environment of a substance specified on the CEPA List of Toxic Substances “Take all reasonable measures consistent with the protection of the environment and public safety to prevent the release”. Similarly, the Environmental Protection Act, R.S.O. 1990, c. E.19 “The owner of a pollutant and the person having control of a pollutant that is spilled and that causes or is likely to cause an adverse effect shall forthwith do everything practicable to prevent, eliminate and ameliorate the adverse effect and to restore the natural environment.”
National Fire Code (NFC 4.1.6 & NFC 4.3.7), “Spill control must include… a non-combustible barrier of sufficient height to contain the spill.” The Ontario Fire Code similarly states in 184.108.40.206. (1) a spill of flammable liquids or combustible liquids shall be prevented from flowing outside the spill area and from reaching waterways, sewer systems and potable water sources by: (a) constructing a noncombustible barrier capable of containing the spill.” This would include natural flooding and fire water control within a room containing flammable substances.
