St John has utilised reflective markings for the last 30 - 40 years. The present day St John marked fleet has a similar amount of 'reflectivity' as most CFS / MFS / SES primary appliances. I would imagine that the current livery review will consider whether additional reflective material use will form part of any new livery designs.
As for the emergencies that St John responds to / attends, well let me see, the list is endless...!!!!
There is everything within an event scope, from cardiac arrest, respiratory arrest, traumatic injury, medical illness, alcohol / drug affected patrons, I could go on and on..
St John also supports a wide range of emergency response at large, complex incidents such as fire, flood, storm events etc. It provides a range of services such as responder welfare management and provision of Health Services. St John also provides support to relief centres ensuring that a level of Health Service is provided to displaced persons affected by emergencies.
St John has several signed MoU's with SAAS regarding service delivery in emergencies.
I trust that the above clarifies the "emergencies" that St John has, does and will be attending.
