This is the dramatic moment ship workers are rescued after scaffolding collapsed while they were working on a cargo vessel - killing one of their friends.

The four men were working on the ship in Zambales, Philippines, on May 12 when a walkway collapsed - sending one man plunging some 30 feet to his death.

Footage taken after the first man died shows the three remaining workers desperately clinging on - with two being caught by colleagues and a third being plucked to safety with a crane.

They were rushed to hospital and treated for minor injuries while colleague Ferdinand Leuterio was later pronounced dead. The injured men were Gerry Bayuta, Johnny Alegre and Vailian Dela Cruz.

Zenaida Angara-Campita, regional labour department director, said: ''Clearly, there was an unsafe working condition because of an overload of workers and their equipment on the scaffolding, causing its sudden collapse.

''Aside from this, unsafe acts were also observed because of workers’ failure to use safety harnesses, as well as their supervisor’s failure to control them on the adherence to safety practices.''

South Korean company Hanjin Heavy Industries and Construction Philippines - known as HHIC Phil. - owns the shipbuilding facility but the workers are under the employment agency Binictican I-Tech Corp., which has been suspended by the Philippines Labor Department.
