Hull Breach (emergency procedures)
3.3 HULL BREACHES
3.3.1 Identification of Hull Breaches
Hull breaches may be identified through either visual inspection of the hull or pressure drops in any parts of the Habitat monitored by EECOM. The fundamental principle of hull breaches is that it is better to be safe than sorry: any suspicion whatsoever of a hull breach should be initially treated as a definite atmospheric leak until it is proven otherwise.
