Because EPIRBs automatically activate when immersed in water, and apparently the crate contains fully enabled units not otherwise held within waterproof packaging, the result would be 1,600 simultaneous signals of a ship sinking. In reality, though, EPIRBs usually require some sort of pre-activation and would not be in an operable state when packaged in transit and prior to sale or installation on a vessel. The text beneath the comic is them calling the Coast Guard to apologize for the overwhelming flood of signals. It appears this is not the first such call they have made, though it is unclear whether they have called multiple times to apologise for the same incident, or they are habitually careless in their handling of these packages.&lt;/div&gt;&lt;/td&gt;&lt;td class='diff-marker'&gt;&amp;#160;&lt;/td&gt;&lt;td style=&quot;background-color: #f9f9f9; color: #333333; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #e6e6e6; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;In the comic [[Megan]] and [[Cueball]] accidentally drop a box {{w|CT#Other uses|containing}} 1,600 EPIRBs into the water while moving it across a gangway between a ship and a dock.

However, the massive flood of signals could affect the response to other, legitimate, emergencies by overwhelming the communications channels. Sources suggest that each satellite can handle 10 to 90 beacons at once in the field of view of a satellite, so 1,600 would clearly clog the bandwidth. Even if all 1,600 signals made it through, taking just a few seconds to acknowledge and clear/delete them would mean an hour or two to remove all 1,600 signals, during which time a legitimate signal could go unseen.&amp;#160; Combining both scenarios - the system only reports 90 signals from the satellite overhead, then several minutes later after they are cleared or a new satellite comes overhead 90 new reports are generated and need to be cleared - could clog the reporting system for many hours.&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
