According to Gwangjin Police Station, the 19-year-old Kim, an employee of a company that Seoul Metro had subcontracted for door maintenance, had been repairing the platform screen door at Guui Station on Saturday evening.
He was working by himself, with neither supervisor nor any signboard to notify approaching train operators.
The authorities have examined surveillance camera recordings and are set to summon related officials for questioning. The probe will be jointly handled by the Ministry of Employment and Labor’s special judicial police and the Korea Occupational Safety and Health Agency.
Is it possible to replace "to notify" with "notifying" in the sentence? and if it possible to do that, is meaning changed after that?
