THE police bomb squad detonated two home-made devices found at the Toowoomba Hospital and a Taylor St home on Monday.
Officers established a 100-metre exclusion zone at the hospital when a suspicious device was found in a car parked at the hospital at 10am.
The hospital was not evacuated, but no-one was allowed to enter the building and staff and patients were moved to a different section.
Toowoomba Police District spokesman Detective Inspector Darren Smith said officers were initially called to a disturbance in the yard of a Taylor St home at 8.45am.
A man, 44, sustained significant burns and was taken to the Toowoomba Hospital by a woman.
Det. Insp. Smith said it was unknown how the man was burnt but a suspicious home-made device was found in the yard. A second device was found in a car parked outside the hospital's emergency department.
Local police cordoned off both crime scenes and waited for the Brisbane bomb squad to arrive.
Both devices were safely detonated Monday afternoon.
Det. Insp. Smith said no threats were made to the hospital.
"Police and Queensland Health staff worked well together to ensure the safety of the community and patients at the hospital," he said.
"Police are calling for witnesses who may have been in the vicinity of Taylor St (near the intersection of Ellis St) at 8.50am."
A Toowoomba Hospital spokeswoman said any patient who missed an appointment would have their appointment rescheduled.
