"A risk assessment of the Piql Services" by FFI

Celsius, but wide spatial variations will be seen. PP is a material that burns easily, and it will melt fairly quickly when exposed to fire. The once hard plastic will turn into a thick, sticky mass. The water from the sprinklers will do no notable damage to plastic of the piqlBox. The piqlFilms near the top of the grid are 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 water from the sprinklers and possibly from fire hoses, if those are needed, can also affect the films. The piqlBox should protect the piqlFilm to a certain extent, but the Box is only splash-proof, not water- proof, i.e. not air-tight, which means that water will seep into the Boxes which are submerged in water. The piqlFilms are unaffected by this so long as they are immediately rewashed and dried properly. The power supply to the piqlVault is highly affected by the electrical fire. The electrical connections powering the piqlVault system are completely cut off, but the generator which the piqlVault is fitted with manages to keep up other functions, such as ventilation. The temperature in the storage room naturally increases rapidly once the fire breaks out as flames generate and release large amounts of heat. Once the sprinklers are turned on, the level of humidity in the storage room also rises, but not notably. The rise in temperature is the bigger problem for the piqlFilms. 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 submerged in water may be compromised if the Films cannot be dried off properly and made safe for handling. The integrity of the remaining piqlFilms is intact, as we assume the fire is put out quickly enough and the splash-proof piqlBox provide sufficient protection against the water from the sprinklers. The availability of all the piqlFilms is compromised temporarily, as the operations of the piqlVault system are halted due to lack of electricity. Should they be needed, however, manual recovery is possible. For the piqlFilms which are damaged beyond repair by the fire, or which cannot be saved after the long exposure to water, availability is
