An escape hood, comprising a respirator, having an air filter suitable for filtering toxic air contaminants and positioning members to retain the respirator in a respiratory path of the user; an optical lens; a expanding member, permitting hood to expand from a compact storage configuration to a usage configuration; a sealing structure, around said air filter, for preserving said filter during storage; and an unsealing mechanism, adapted to allow a user to withdraw the escape hood from a storage vessel, wherein during withdrawal, said sealing structure is automatically unsealed. An escape hood system is also provided, comprising: an array of storage vessels, each vessel being adapted to receive a sealed escape hood; a retainer, for retaining a sealed escape hood within the vessel, wherein the escape hood is unsealed during withdrawal of the escape hood from a storage vessel; and an electronic sensor for determining an occupancy of a storage vessel.

The escape hood system according to claim 2, wherein said array of storage vessels, or an escape hood stored therein, comprises an audio input device. 10. The escape hood system according to claim 2, wherein said array of storage vessels, or an escape hood stored therein, comprises a battery. 11. The escape hood system according to claim 2, wherein said electronic sensor for determining a presence of an escape hood in a storage vessel determines an identity of an escape hood stored in said storage vessel. 12. The escape hood system according to claim 2, wherein said array further comprises a data logger for electronically recording locally, or transmitting remotely, the occurrence of events. 13. The escape hood system according to claim 2, wherein said array further comprises an input for determining an identity of a person removing an escape hood. 14. The escape hood system according to claim 2, wherein said array comprises a radio frequency communication device. 15. The escape hood system according to claim 2, wherein an escape hood comprises an internal self-diagnostic system. 16. The escape hood system according to claim 2, wherein an escape hood is automatically activated for use upon removal from the array. 17. The escape hood system according to claim 2, wherein an escape hood comprises an air filter, sealed during storage, wherein said air filter is automatically unsealed upon removal from the array. 18. The escape hood system according to claim 2, wherein said mechanism restricting insertion of an unsealed escape hood in a storage vessel comprises an electronic element. 19. The escape hood system according to claim 2, wherein a plurality of arrays communicate electronically with a remote central system. 20. The escape hood system according to claim 2, wherein said retainer is electronically controlled to prevent unauthorized removal of an escape hood from said array. 21. The escape hood system according to claim 2, wherein an escape hood is sealed with a polymer film, said retainer being associated with a cutting edge to perforate said polymer film upon removal of said escape hood from said array. 22. The escape hood system according to claim 2, wherein an escape hood complies with EN 403. 23. The escape hood system according to claim 2, wherein an escape hood comprises an air filter, wherein said air filter is replaceable. 24.
