Labour representatives on Sunday said more needs to be done to ensure occupational safety, after a recent spate of fatal industrial incidents.

The Association for the Rights of Industrial Accident Victims’ chief executive, Siu Sin-man made the remarks on a radio programme less than a month after two workers died while replacing pipes underground near Elements shopping mall in an apparent gas poisoning.

Siu said employers and workers have to work together to prevent tragedies from happening again.

"Current safety regulations and technology are comprehensive, but the problem is whether [the construction sector] has complied with them and put safety first instead of costs. And for employers, have they exercised their power and resources to ensure safety and convey the message to frontline staff?"

"Of course, this is also an issue for frontline workers...every party has responsibility," she added.

Engineering sector lawmaker Lo Wai-kwok, meanwhile, said more safety education is needed.

"It's actually more important to build up [a culture of safety], and all stakeholders should [put] safety first as what they have to do in day-to-day operation of the construction sites, or other industrial or business set ups," he said.

Lo also thinks the sector can make use of new technology to improve safety, such as locating workers at construction sites.

Speaking on the same radio programme, unionist lawmaker Kwok Wai-keung called for a thorough review of "Aggressive Construction", a building firm linked to a string of construction deaths.

Aggressive Construction is currently suspended from bidding for government projects, after three of its workers were killed in a crane collapse on Anderson Road in September last year.
