ACCEPTABLE SEPARATION DISTANCE (ASD), a regulatory indicator in the United States to protect human and building/structure from explosion/fire, associated with chemicals.

There’re two safety standards in 24 CFR Part 51, United States to calculate ASD.

1) Structures

• Thermal Radiation (fire) – 10,000 BTU /Ft. sq Hr. (31.5 kW/m²)
• Blast Overpressure (explosion) – 0.5 PSI (105 Kpa)
  
  

2) Human

• Thermal Radiation (fire) – 450 BTU/Ft. sq Hr. (1.4 kW/m²)

ASD Electronic Assessment Tool is available at;

Just note to remind you that calculation of the ASD is the first step to assess site suitability.
