Bio

Mr. Sng joined MOM in 1997 as a safety inspector and in the course of his career, Mr. Sng had assumed various leadership roles such as Director, OSH Inspectorate; Director, Work Injury Compensation Department and Deputy Executive Director, Workplace Safety and Health (WSH) Council. Mr. Sng was instrumental in the development of the current Workplace Safety and Health Act that was enacted in the aftermath of the 2004 Nicoll Highway Collapse.  On 1 April 2019, Mr. Sng was appointed as the Divisional Director for the Occupational Safety and Health Division, Ministry of Manpower.  He is entrusted with the honour and responsibility to lead OSHD to achieve the next level of WSH improvements for Singapore guided by the new WSH2028 strategies.

Abstract

OSH professionals in Singapore have contributed significantly to the remarkable improvements to our workplace fatality rate over the last 15 years.  Many have acquired new skills and competencies.  Even as we sustain the improvements, there are many workplace health challenges confronting OSH professionals.  Traditional hazards continue to plague workers causing them to become ill.  There are probably new or unknown hazards at the workplace as well.  At the same time, our workforce is aging, and many will experience chronic illness that can affect safety at work.  This presentation will discuss these challenges that confronts all practicing OSH professionals and how we can better prepare ourselves to cope with these challenges.

Abstract

The nature of work is evolving, with changing patterns of employment and the emergence of novel hazards. Technology has become more pervasive - it often helps but can sometimes blur the lines between work and leisure. An ageing workforce, seen in many countries gives rise to new health challenges. Work-related diseases such as mental health disorders are gaining prominence. Traditional approaches in disease prevention that work for chemical, physical and biological hazards may be ineffective in managing psychosocial hazards. The adoption of a total WSH approach is also ground-breaking, as it is now generally recognized that occupational ill health results in greater mortality and morbidity than occupational injuries. The new Vision zero not only applies to accidents, as in the past, but also to diseases. For us to better prepare for OSH disruption due to new technology, we must keep abreast of developments, embrace change, be aware of hype, and ensure that policy, regulations and ethics keep up with technology.

At the same time, OSH foundations need to be maintained and strengthened. The emphasis on primary prevention should remain our focus, but secondary and tertiary prevention should not be neglected. Some jobs and occupational hazards will remain the same – so training needs to be given for both traditional as well as non-traditional risks and concerns. Increasingly, OSH professionals may be asked to deal with environmental health issues, which often arise from the workplace as a source of pollution. This requires mastery of traditional skill sets in OSH such as hygiene, toxicology, risk assessment and risk management. As OSH is a practical discipline, we need ensure that we do not lose our hands-on approach, interact with workers, and visit and assess the workplace. Expectations from management and workers will rise, and these can be met by OSH professionals working in a professional, impartial, ethical and caring manner.

Abstract

Total Worker Health® is a holistic approach to worker wellbeing that integrates protection from work-related safety and health hazards with promotion of injury and illness prevention efforts. Organizations that have integrated their health protection and health promotion programs can potentially expect improved employee wellbeing, reduced healthcare costs, increased productivity, and improved organizational performance. Successful design and implementation of a TWH program in an organization requires knowledge and skills traditionally “owned” by a range of occupational and environmental safety and health (OESH), medical, human resource, and business professionals. An emerging professional specialty in TWH that integrates competencies from these disciplines is supported by an expanding list of peer-reviewed literature, as research adds to the body of knowledge of TWH.

This presentation will provide an overview of TWH followed by practical suggestions for OESH professionals to implement TWH in their workplaces.  The TWH hierarchy of controls will be presented as a practical approach to recognition, evaluation, control, and communication of workplace health issues such as opioid abuse and psychosocial stress.

Abstract

Heat injury is a major concern in occupations settings, especially in industries where the workers are exposed to hot and humid environment. Protecting workers from the risks of heat injury will become even more important in the next decade, due to the effects of global warming.

For more than 2 centuries, heat injury has been attributed mainly to hear stress and dehydration. These concepts of heat injury have become the foundation for strategies to prevent heat injury in sports, occupational and civilian settings globally e.g. avoidance of heat stress and ensuring a state of hydration. However, research evidence in the last 15 years have provided new evidence to suggest that there are non-heat-related factors that can also cause heat injury.

This presentation will discuss this new evidence in occupational context and strategies that can be taken to further reduce the risks of heat injury. With better appreciation on the causes of heat injury, stakeholders in occupational safety would be in a better position to take effective measure to protect workers from this fatal occupational hazard.

Abstract

Occupational hearing loss has been related to noise-induced hearing loss for many years but is far more complex than we knew before. It is now known that the occupational exposures to ototoxic chemicals (e.g. solvents, metal and compounds, asphyxiants, nitriles etc.) alone as well as the combined exposures to noise AND ototoxic chemicals can cause hearing loss among the exposed workers. Additional risk factor is the synergistic effects of both noise and ototoxic chemicals in the combined exposures. Despite these recent findings, it is unlikely that the current occupational exposure limits for noise (8-hour equivalent noise exposure of 85 dBA and 3 dB exchange rate) will be revised soon.

Relative to noise, workplaces are less familiar with ototoxic chemicals and should catch up as early as possible with the much-needed work on these chemicals, starting with identification of ototoxic chemicals and product ototoxic ingredients in their workplaces, and adoption of basic control measures including substitution and elimination. Following risk assessment, workplaces may expand their existing air monitoring programs targeting the ototoxic chemical exposures.

Workplaces should step up their prevention efforts on occupational hearing loss by expanding and updating their existing hearing conservation programs to include those workers with lower noise exposures (i.e. LAeq 8h <85 dBA) in the noise monitoring and medical surveillance programs, and also include those workers exposed to ototoxic chemicals in the hearing conservation and audiometric testing programs, even if they are not exposed to noise.

Total protection of hearing health at any age, and prevention or management of any type of hearing loss are needed to address this common health issue. The effectiveness of preventing occupational hearing loss goes beyond the sole efforts focusing on regulation compliance.
