<br />Model 244 Emergency Vents I 8 -inch
<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 />application of this vent requires proper vent size and selection for the
<br />tank system in order to meet the specific venting capacity.

<br />tank vents are designed only for use
<br />on shop fabricated atmospheric tanks
<br />which have been built and tested in
<br />accordance with UL 142, NFPA 30 &
<br />30A, and API 650 and in accordance
<br />with all applicable local, state, and
<br />federal laws. In normal operation, dust
<br />and debris can accumulate in vent
<br />openings and block air passages.
<br />Certain atmospheric conditions such as
<br />a sudden drop in temperature, below
<br />freezing temperatures, and freezing rain
<br />can cause moisture to enter the vent
<br />and freeze which can restrict internal
<br />movement of vent mechanisms and
<br />block air passages. All storage tank vent
<br />air passages must be completely free of
<br />restriction and all vent mechanisms must
<br />have free movement in order to insure
<br />proper operation. Any restriction of
<br />airflow can cause excessive pressure or
<br />vacuum to build up in the storage tank,
<br />which can result in structural damage
<br />to the tank, fuel spillage, property
<br />damage, fire, injury, and death. Monthly
<br />inspection, and immediate inspection
<br />during freezing conditions, by someone
<br />familiar with the proper operation of
<br />storage tank vents, is required to insure
<br />venting devices are functioning properly
<br />before filling or unloading a tank.
