She added: "This applies not only within companies, but also extends to subcontractors and suppliers. Conversely, if the senior management shows little or no interest, it is unlikely that the rest of the company or its associates will take WSH seriously."
John Ng, chairman of the WSH Council, added that helping companies and developers to better understand contractors' commitment to OSH when deciding project tenders would "encourage more contractors to invest in improving their safety and health record".
Teo noted how some companies now require their subcontractors to have bizSAFE Level 3 certification as a minimum -- a practice that government agencies already adopt when they award public construction project tenders.
"When the customer imposes such a requirement, it reinforces the importance of safety and health in the workplace," she said.
"Both sides also stand to gain from reduced downtime due to accidents or costs incurred because of safety lapses."
The Manpower Minister said that the TSC had started to consult with key industry stakeholders, including employers, unions, professional associations, safety officers and workers from different industries on how workplaces can be safer and healthier. She added that a recurring theme from these discussions was that senior management should take the lead in driving WSH.
