Two persons died on the spot when a tyre they were fixing exploded at Hwidiem in the Asante Akyem North District of Ashanti Region.
Two others, who sustained various degrees of injury, are currently responding to treatment at the Agogo Presbyterian Hospital.
The two, who died on the spot, included a steel welder and a tricycle rider, who brought a defective tyre of a heavy duty vehicle for repairs.
According to the police, the welder with the assistance of the motorbike rider ignored the safety precaution of deflating the tyre before working on it.
Few minutes later, the tyre exploded and chopped off the head of the steel welder and also mutilated that of the motorbike rider beyond recognition.
Two other persons including a 14-year-old boy who were standing close-by the scene of the accident also suffered injuries from the explosion.
The 14-year-old boy, Kojo, got injured on his left leg whilst a 30-year old man suffered severe injury on his head.
The injured are currently in stable condition.
The Agogo Police Commander, ASP Samuel Kojo Azubu, said investigations have commenced to establish the actual cause of the accident.
He advised the public to adhere to safety precautions at work places.
The bodies of the two have been deposited at the Agogo Presbyterian Hospital morgue.
