Before work starts, the workforce must be briefed on what they need to do in case of an alarm or alert

HRS provides example briefing sheets (toolbox talks). It is important that both day and night-time staff liaise with the client to ensure the workforce are briefed. There is no set way to deploy Blue Portable Site Alarms, as long as the workforce will be within sight and hearing distance of the alarm. In some cases, clients request these to be positioned every few hundred yards throughout the closure.
