"A risk assessment of the Piql Services" by FFI

does not cause the entire structure to collapse, as the stacking of the piqlBins help to keep it upright.

The piqlBoxes that are in contact with the flames and in their near proximity will be severely affected by the fire. The PP in the piqlBoxes has a melting temperature of 170° Celsius, and regular room fires can reach between 600 and 1200° Celsius. The PP will therefore melt fairly quickly, especially when exposed to fire for a longer period of time as the extreme temperatures are sustained. The once hard plastic will turn into a thick, sticky mass. If the piqlBoxes come in contact with the melted aluminium of the grid, that will cause more damage as well. The piqlBoxes which do not melt have still been subjected to extreme temperatures. They will need replacing, as their structural integrity has been compromised and their longevity can no longer be guaranteed. The piqlFilms that are in contact with the flames and in their near proximity will be severely affected by the fire. The PET in the piqlFilms has a melting temperature at approximately 260 o Celsius, but already at a temperature of 75° Celsius the properties of the PET will change a lot. What happens is the same as when glass is heated; it will get softer and more viscous. If the piqlBox serves to protect the Films from some of the heat, it may well be that the melting PP of the Box will damage the film where the materials come in contact. The piqlFilms which do not melt have still been subjected to extreme temperatures. This will also affect the readability of the piqlFilm, as everything will get blurred. The forest fire causes a general power outage in the area near the piqlVault, but the generator which the piqlVault is fitted with manages to keep up other functions, such as ventilation. When the fire reaches the building, however, the electrical wiring short-circuits and all power supply is lost. The temperature in the storage room naturally increases rapidly once the fire breaks out as flames generate and release large amounts of heat. The flames, of course, do the most damage, but the rise in temperature in the confined space will increase the negative effect on the remaining piqlFilms.

Security mechanisms

The piqlFilms that are in close proximity to the fire will be beyond repair and the data will be lost. It will no longer be possible to verify the integrity of the information. The information on the piqlFilms that are subjected to the extreme heat may blur, depending on the proximity to the fire source.

Integrity

The damage, however, would have been far greater without the oxygen
