FFI-RAPPORT 16/00707
The emulsion layer of the piqlFilm, made of gelatine, will react violently with
the chlorine gas. At very little exposure it will start to corrode and completely
dissolve.
Additional note: The gelatine will have this reaction with many chemical
agents, not just chlorine gas. Exposure to chemical agents should be avoided.
Power/energy supply The power supply is not affected by the chlorine gas.
Divergence from
ISO standard
Spin-off effect of scenario cause secondary incident: When the doors are left
open to facilitate the evacuation of personnel, not only is the chlorine gas
allowed to enter the piqlVault; hotter and more humid air than what is allowed
inside the Vault according to regulations is let in as well. However, this will
not cause much damage; it is the heightened negative effect of the chlorine gas
due to higher temperatures and levels of humidity that is the culprit.
Security mechanisms
Integrity
The gelatine emulsion of the PiqlFilms exposed to the chlorine gas will
completely dissolve. This entails damage beyond repair, and the data will be
lost. It will longer be possible to verify the integrity of the information.
Availability
See over. The information will no longer be available to the owner.
Confidentiality
See over. Although information will no longer be accessible to the data owner,
neither will they be accessible to anybody else. Confidentiality thus remains
intact, as no one else can or will read the material.
All the piqlFilms in the vault were, however, left without proper security
regarding access control when the doors were left open and could
hypothetically have been accessed by others at this time. Other circumstances
(protected by the gas) made sure no unwelcome persons dared come near the
piqlFilms.
Immunity (against
attacks on the above
mentioned)
The Piql Preservation Services is not immune to attacks on availability or
integrity.
Recommendations
Recommended
protective measures
As the risk in this scenario does not represent a direct targeting of the Piql
Preservation Services, and was rather a general hazard to all in the affected
area, the only advice one can give is ―Beware of your surroundings‖. When the
piqlVault is situated near an industrial area with chemical plants, exposure to
chemical agents is a risk. Either the Piql partner must take the necessary
precautions, for instance installing air tight doors which shut automatically, or
make the executive decision to place the piqlVault elsewhere, not in a high risk
occupancy.
Also, particularly when it comes to heavy gases such as chlorine gas, a specific
