SINGAPORE: The heart of the country was shaken by a chemical gas attack at a crowded office building, followed by an explosion and lone gunman at a tourist hotspot - all simulated as part of Exercise Heartbeat, an annual emergency preparedness exercise organised by the Singapore Police Force and Singapore Civil Defence Force.
First, a Sarin gas attack was staged at One Marina Boulevard.
SCDF officers in protective equipment attend to Sarin gas "victims" at One Marina Boulevard.
SCDF officers aim to respond within 8 minutes from the moment an emergency call is received. Upon arrival, they will prioritise casualties, evacuate the building and mitigate the source of the chemical agent.
All fire engines are equipped with hazardous materials detectors to help identify the chemical agent.
Exercise Heartbeat: SCDF officers prepare to "decontaminate" a victim of a staged chemical attack. They will first remove all his clothes, then wash him with soap and water.
Next, an improvised explosive device was activated at Esplanade Park, not far from the scene of the gas attack.
A lone gunman then began shooting at members of the public, according to the exercise scenario.
Officers from the Singapore Police Force counter-terrorism unit moved in to subdue the lone gunman.
