High-output Maxi Fire-Cryer® Voice Sounders from Vimpex Limited have been used to solve a challenging voice evacuation project at St. James Wholesale Market in the heart of Bradford. Multi-message voice sounders were identified as significant safety enhancements in the event of an incident at the market. However, justifiable concerns were raised on the question of how to clearly and unambiguously communicate evacuation or emergency messages to those workers whose first language is not English.
