As an extreme example I'm reminded of this south korean ferry disaster where 304 passengers died:
> As Sewol began sinking, the ferry's intercom system started ordering the passengers to stay put, alleging that moving was dangerous. The announcements were made by a communication officer, Kang Hae-seong, who had not consulted the manual before the broadcast. The announcements began broadcasting by at least 8:52 a.m. and continued even when water began flooding passenger compartments. Other crew members corroborated this order, instructing passengers to stay put. Captain Lee also instructed passengers to stay put and did not change the order even as he was leaving the ship.
> The first emergency call was made by Choi Duk-ha, a Danwon High School student aboard the ferry. At 8:52 a.m., he called the national emergency service number and reported to the Jeollanam-do fire station that Sewol was capsizing.
