fire water containment requirements

In the event of a fire, the loss of containment of such substances, along with the generation of fire-fighting water run-off, can lead to significant environmental incidents, including the contamination of rivers, streams, groundwaters, soils, and effluent treatment works. In the event of a fire, the loss of containment of such substances, along with the generation of fire-fighting water run-off, can lead to significant environmental incidents, including the contamination of rivers, streams, groundwaters, soils, and effluent treatment works. The purpose of this chapter is to clarify the relationships among the various general and specific secondary containment requirements of the SPCC rule, and to illustrate how these . Other methods of fire water management To prevent fire water from causing pollution, containment is the best method. The scope of this Fire Safety Guidelines covers the fire safety requirements for high containment facility or laboratory that handles biological agents or toxins, designed to meet the WHO and MOH's requirements of Bio-Safety Level 3 [BSL-3] or higher. The IFC adds to this, stating the slope of floors shall not be less than 1%, drains for indoor storage areas shall be sized to carry the volume of the fire protection water as determined and drains for outdoor storage areas shall be sized to carry the volume of the fire flow and the volume of a 24-hour rainfall as determined by a 25-year storm. NFPA® 10 NFPA 30 2000 Edition • (6) Certain rigid nonmetallic intermediate bulk containers are now recognized in Chapter 4. This can reduce the amount of water needed to control or extinguish a fire, which in turn reduces the cost and scale of other facilities. • (7) The requirements for spill containment and drainage have been simplified, and new design criteria for warehouse drainage systems have been added to the In all cases, fire water must be fully contained. fire water run-off - means residual water used in fighting the fire, which is contaminated . Fire safety requirements still apply to waste facilities not covered by this guideline. For an example, a room with a 300 gallon vessel, a containment area of 160 SF, and a sprinkler flow of .35 GPM/SF, will result in a containment depth of 1′-8″. The following table summarizes secondary containment regulations. In addition, some of these methods may allow the recycling of fire water if a risk assessment determines it is possible.
