QUANTITY The discharge of carbon dioxide into an enclosure will displace a portion of the atmosphere in the enclosure The displaced atmosphere is exhausted freely from the enclosure through openings or vents as the carbon dioxide is discharged Since some suppression agent is lost with the vented atmosphere the volume of carbon dioxide required to develop a given concentration will be greater than the volume that actually remains in the enclosure This method of application is called free efflux flooding A small volume has proportionally more surface or boundary area per unit of enclosed volume than a larger volume and has a proportionally greater leakage rate Accordingly larger quantities of carbon dioxide per unit of enclosed volume are injected into smaller volumes to account for the higher leakage rates anticipated upon discharge The quantity of carbon dioxide per unit volume is called the Volume Factor and is shown in Table 3 2 Also note that the minimum quantity of is specified for the smallest volume in each group to avoid a possible overlap of requirements Equation 1 W V f or Where Wg Basic quantity of agent Ib kg V Enclosure volume ft m f Volume factor from Table 3 2 ft 3 Ib m kg f Volume factor from Table 3 2 Ib ft kg m Table 3 2A Volume Factors Surface Fires For 34 CO Concentration US Units Volume Factor Calculated Quantity Enclosure Volume ft 3 fi h ft 3 Ib Ib
