Since it is assumed that children and the elderly could not take refuge behind walls or run away from the thermal effect of the fire within the 15 seconds before skin blistering occurs, unprotected (outdoor) areas, such as playgrounds, parks, yards, school grounds, etc., must be placed at such a distance from potential fire locations so that the radiation flux level is well below 1500 Btu/ft (1) Introduction.

This is the actual setback required for the safety of occupied buildings and their inhabitants, and people in open spaces (exposed areas) from a potential fire hazard. Since the reasonable response time for fire fighting units in urbanized areas is approximately five to ten minutes, a standard of 10,000 BTU/hr.

Liquid propane is used in the example since it is both an explosion and a fire hazard. Then draw horizontal lines from the points where the lines cross to the left vertical axis where the ACCEPTABLE SEPARATION DISTANCES of 240 feet for buildings and 1,150 feet for exposure to people is found. Toxic Chemicals and The project does not involve new development for habitation; Responsible entities are advised not to Application of the standards can be eliminated or modified if: (a) The nature of the topography shields the proposed project from the hazard. The Technical Guidebook entitled “Urban Development Siting With Respect to Hazardous/Commercial Industrial Facilities,” which supplements this regulation, contains the technical guidance required to compute Acceptable Separation Distances (ASD) for those flammable substances most often encountered. The following example is given as a guide to assist in understanding how the procedures are used to determine an acceptable separation distance. CFR. Nomographs from the technical Guidebook have been reproduced to facilitate the solving of the problem. For example, conventional petroleum fuel products stored in unpressurized tanks do not emit blast overpressure of dangerous levels when ignited.

It has been determined by the military and corroborated by two independent studies conducted for the Department of Housing and Urban Development that 0.5 psi is the acceptable level of blast overpressure for both buildings and occupants, because a frame structure can normally withstand that level of external exertion with no serious structural damage, and it is unlikely that human beings inside the building would normally suffer any serious injury.
