<br /> SPECIFICATION SHEET
<br /> Application
<br /> UL Listed emergency vent (pressure relief only) used on aboveground
<br /> storage tanks, as a code requirement, to help prevent the tank from
<br /> becoming over-pressurized and possibly rupturing if ever exposed to
<br /> fire. The vent must be used in conjunction with a "normal vent." Correct
<br /> i
<br /> application of this vent requires proper vent size and selection for the
<br /> tank system in order to meet the specific venting capacity.
<br /> Code Compliance
<br /> When properly sized for the tank, this vent will conform to the Fig.2440M
