Air shows, and other big shows such as agricultural shows, on grassy land, are vulnerable to continued heavy rain waterlogging the ground, and making the cloudbase too low for flying, forcing cancellation, or the show ending early, costing much money for the show's organizers, as people and parking cars have difficulty moving about and turn the land into a morass, and the organizers may be tempted to put straw or cinders down to make movement easier, and the owner of the land cannot accept the resulting damage.

Particularly with some lower-priced embossers, it is sometimes necessary to mount the embosser on its own table, as otherwise the vibrations can damage the computer by eventually causing microchips and other components to come loose from the circuit boards.

Both ships were soon fighting enemies much more powerful than themselves and began to take severe damage: Captain Henry Darby on Bellerophon missed his intended anchor near Franklin and instead found his ship underneath the main battery of the French flagship, while Captain George Blagdon Westcott on Majestic also missed his station and almost collided with Heureux, coming under heavy fire from Tonnant.

Other areas damaged during World War II bombing included: in September 1940 two unexploded bombs hit the Edward VII galleries, the King's Library received a direct hit from a high explosive bomb, incendiaries fell on the dome of the Round Reading Room but did little damage ; on the night of 10 to 11 May 1941 several incendiaries fell on the south west corner of the Museum, destroying the book stack and 150, 000 books in the courtyard and the galleries around the top of the Great Staircase – this damage was not fully repaired until the early 1960s.

If a second compression test is performed shortly thereafter, and the new reading is much higher, it would be the ring seal that is problematic, whereas if the compression test pressure observed remains low, it is a valve sealing ( or more rarely head gasket, or breakthrough piston or rarer still cylinder wall damage ) issue.

If the valve sticks open, rather than causing an overflow and damage, the tank spills into an overflow.

Trigger leaves behind the air hose and closes the second valve, but the damage causes pipes to collapse, trapping his leg, and he drowns.

Thermionic valve equipment usually does not have the valves mounted on the PCB, to avoid heat damage, but uses PCBs for the wiring, achieving the economy of mass-produced PCBs without the heat damage.

Self-ignition leads to inefficiencies ( or even engine damage ) if it occurs during compression prior to the desired position of the piston in the cylinder as appropriate for valve and ignition timing.

The Three Mile Island accident was caused by a stuck-open pilot-operated pressure relief valve combined with a deceptive water level gauge that misled reactor operators, which resulted in core damage.

Another theory postulates that it may function as a " safety valve ", preventing the excess of reductive potential coming from an overreduced NADPH-pool from reacting with oxygen and producing free radicals, as these can damage the metabolic functions of the cell by subsequent oxidation of membrane lipids, proteins or nucleotides.
