Specialist police have reimposed an emergency order on streets surrounding a West Ipswich home where a chemical explosion injured two men on Thursday night.

One man was left with just a thumb and forefinger on one hand, along with significant injuries to the other hand and his groin, following the explosion at a Clay street home about 6.30pm.

The bomb squad imposed an emergency order shortly after arriving at the scene but lifted it just before 4am Friday, following three controlled explosions of dangerous chemicals found at the house.

They reimposed the order this afternoon, while continuing their investigation into the incident. Residents in surrounding areas have been advised to remain inside as a precautionary measure.
