Communicating Safety Precautions in a Multi-lingual City

[NoelMooreTRU]

Sampson (2006), in "A survey of public perception and response to heat warnings across four North American cities: an evaluation of municipal effectiveness", has found that "the effectiveness of the communication of safety precautions to different populations needs improvement". He also identified that "there is a need for more effective communication with people who are vulnerable that they need to be concerned about their safety". 

What do you think could improve this problem?
