"A risk assessment of the Piql Services" by FFI

fall out, as the piqlBoxes are placed four to a piqlBin and stacked fairly tightly. However, some of the piqlBoxes are damaged by the pieces of concrete which are propelled into the grid. All of the piqlBoxes need to be replaced, however, as their structural integrity has been compromised and their longevity can no longer be guaranteed. The piqlFilms are not harmed by the explosive blast other than the pressure wave causing the piqlBoxes to slam into the piqlBins and thus shifting the piqlFilms a little inside the piqlBoxes. However, some of the piqlFilms are damaged by the pieces of concrete which are propelled into the grid. Even though the majority of the piqlFilms survived the initial blast and pressure wave, they are left exposed to the elements for several days before the building is declared safe for entry and the repair work can start. As it is winter in southern Europe when this scenario takes place, the effects on the piqlFilms are not very severe, as colder temperature and lower levels of humidity has less damaging effect on the piqlFilms than hotter temperatures and levels of humidity. The piqlFilms can become brittle and crispy when exposed to colder temperatures for longer periods of time, but so long as they are heated under controlled conditions before handling they should be fine. The blast causes damage to electrical wiring, which means that the power supply is cut off and the ventilation shuts off. The backup generators are affected by this as well, so they cannot be put to use. The power supply to the piqlVault is completely cut off by explosive blast. Neither is the backup generator able to bring the power supply back up. The loss of ideal storage conditions is worsened when cold air is allowed to flow freely into the piqlVault, as the outer walls of the building and the storage room are gone. The integrity of most of the piqlFilms remains intact during the explosion, as only the pressure wave and not the explosives themselves reach the piqlVault. The piqlFilms that are crushed by the pieces of concrete from the storage room wall are beyond repair and the integrity is forever lost. If the remaining piqlFilms are exposed to the cold temperature for too long, and they are not conditioned right before handling, this too may affect the integrity of the piqlFilms. The availability of all the piqlFilms is compromised temporarily for two reasons: first, that the building was unsafe to enter for several days; and second, once Piql personnel could get into the building, due to the necessary repairs and, in part, demolition of the piqlVault system grid. As the grid was so badly tilted, the manual recovery mechanism was unavailable as well.
