Ng didn’t ensure safe working procedures: DPP

In response, Deputy Public Prosecutor Agnes Chan said the fact that the team carried out prohibited live racking, or that the dislodged piston jammed the circuit breaker, only shows how the explosion happened chronologically.

“These two (factors) do not detract from how the agency and Ng’s failures had contributed to the two deaths and one serious injury,” said the prosecutor.

The DPP said the PTW system was defective as it lacked an essential gatekeeping function that would promote safety in work procedures, allowing those without the necessary qualifications to issue permits for hazardous work.

Ng was also at fault as he did not make clear the safe working procedures for high-voltage switchgear racking work at the TIP.

“Ng did not exercise due diligence to ensure the agency established clear, safe working procedures. There were no clear instructions given to the workers on the day of the accident that could guide them in such a high-risk environment where they are working with high-voltage apparatus,” added the DPP.
