At times of public or private emergency, expectations of modest dress may be suspended if necessary. For example, during suspected anthrax attacks in 1998 and 2001 in the United States, groups of people had to strip to their underwear in tents set up in parking lots and other public places for hosing down by fire departments.[6] On the other hand, even in an emergency situation, some people are unable to abandon their need to hide their bodies, even at the risk of their life.[6] This may apply to decontamination after a chemical or biological attack, where removal of contaminated clothing is important, or escaping from a night-time fire without time to dress.
