Hong Kong issues second amber alert under new heat-warning system for workers amid industry calls to boost public awareness

Hong Kong on Friday briefly issued its second amber signal under a new heat-warning system after the first alert a day before went unnoticed by many workers, amid calls from industry leaders for authorities to strengthen public communication.

The latest amber signal was issued at 10.40am and cancelled an hour later, with the Labour Department appealing to outdoor labourers and those working close to heat sources or in environments without air conditioning to take appropriate measures to prevent heatstroke.
