The 45kg ballistic-plated suit and helmet gave bomb squad officers some confidence as they carefully took the highly volatile TATP explosives out of blast boxes and lowered them into the ground at Gloucester Park to blow them up.
The EOD 9 body armour, which limits air, vision and movement, is used by WA Police and law enforcement agencies around the world.
The bulky suit is designed to stop shrapnel from an exploding bomb tearing into a bomb squad officer's body and protect them from the pressure of a blast wave.
Officers can also wear a protective garment underneath to provide some cover from chemical and biological blasts.
Unlike ballistic body armours, which focus on protecting the head and upper body, bomb suits cover the whole body and consist of a jacket, groin protector, trousers and boots.
The TRG's bomb response unit had to dispose of 3kg of TATP on Wednesday after transporting it in five trips from nearby crime headquarters.
The bomb response unit is called out about three times a fortnight to deal with bomb threats, suspicious packages, recover stolen explosives or deal with people who have made incendiary devices.
