Can the safety distance from buried storage tanks in petrochemical facilities to the perimeter wall be reduced by 50%?
Thread Content
The petrochemical regulations state that the fire separation distance between buried storage tanks and other facilities can be reduced by 50%; does this refer to fences as well?
According to the petrochemical regulations, the fire separation distance between buried storage tanks and other facilities can be reduced by 50%. However, whether it is possible to reduce the safety distance from the wall by 50% depends on a comprehensive consideration and evaluation of the actual conditions on site. It is recommended to avoid reducing the safety distance too much, provided that safety standards are met. .
According to petrochemical standards, note 5 contains a description stating that buried storage tanks can reduce the fire separation distance; therefore, in accordance with “Table 4.2.12”, only those specified in the horizontal notes of note 5 meet the requirements. Since the enclosure wall is not within the field indicated by “Note 5”, the spacing cannot be reduced.
