SHAH ALAM: A dispute on the formula used to calculate the force of impact of the Emergency Medical Rescue Services (EMRS) van that hit fireman Muhammad Adib Mohd Kassim on the morning of Nov 27 last year (2018) continues in the inquest into his death.
Forensics expert Dr Ahmad Hafizam Hasmi on Friday (May 17) maintained his stand that the impact from the door of the EMRS van that hit Muhammad Adib was enough to cause fractured ribs.
He refuted retired pathologist Dr Shahrom Abd Wahid's theory that the impact was not enough to cause injuries to Muhammad Adib.
Dr Shahrom had earlier told the coroner's court that based on his calculation, the impact force that hit Muhammad Adib was just 800N (Newton units).
This, he said, was not enough to cause rib fractures on the fireman, which he theorised would require an impact force of at least 2,500N.
The dispute over the formula started when Dr Ahmad Hafizam said the formula used by Dr Shahrom did not include the weight of the EMRS van.
He said the weight of the EMRS van needed to be taken into account when making the calculation.
"There is force of impact from the van and this was transferred to the victim (Muhammad Adib).
"We cannot just take the victim's fall into calculation, as the victim did not fall on his own.
"He fell due to the impact on his back," explained Dr Ahmad Hafizam.
He then told the coroner's court that he had done his own calculations based on Dr Shahrom's suggestion in court.
But he said he had not come across any academic literature that suggested how many Newton units were needed to break a person's bones.
"I couldn't find anywhere how much force is needed to cause bone fractures.
"The figure I used (2,500 N) was the one that Dr Shahrom suggested," said Dr Ahmad Hafizam, adding that based on the two calculations that he did, the impact force that hit Muhammad Adib was more than 3,500N.
Dr Ahmad Hafizam, who conducted the autopsy on Muhammad Adib, has made nine appearances in the coroner's court.
Due to the dispute over the formula used to calculate the impact force that hit Muhammad Adib, lawyer Syazlin Mansor – who represents the Housing and Local Government Ministry, Fire and Rescue Department and the family of the deceased at the inquest – asked for a mechanical engineer to be brought into the inquest.
Inquest conducting officer Faten Hadni Khairuddin suggested an independent mechanical engineer be consulted.
Judge Rofiah Mohamad, who sits as coroner for the inquest, allowed a mechanical engineer to be consulted.
Muhammad Adib, 24, became critically injured in the early morning of Nov 27 after he and his team members from the Subang Jaya fire station responded to an emergency call at the Seafield Sri Maha Mariamman Temple where a riot was taking place.
The fireman was taken to SJMC after he was found injured, before being transferred to the National Heart Institute (IJN) for further treatment, where he died on Dec 17, at 9.41pm.
The inquest, held at the Shah Alam Sessions Court, continues on Monday, May 27.
