What is WSH Case Studies
WSH Case Studies is a free resources for various groups from management and safety professionals to supervisors and workers for improving WSH practices .
It offers insights to past accidents that have taken place in Singapore. The case studies not only provide lessons learnt for the industry, but more importantly, they remind us to actively review our current practices and continually find ways to make our workplaces safer. Readers are encouraged to carefully think through each case, review its relevancy and context to specific workplace situations, and incorporate the lessons learnt where appropriate.
Here are some workplace accidents case studies for your review
1)WSH Case Studies - Chemical Industry
This booklet is divided into various sections according to type of incident for easy reference. The 5M (Mission, Man, Machine and Management, Medium) Model (see Appendix B) is used to analyse the contributing factors of each case. At the end of the booklet is a section on occupational health hazards. Unlike safety hazards, consequences posed by occupational health hazards may not be as obvious and immediate. Adverse health effects may be chronic in nature and can take a long time for the occupational disease to manifest. This section will show innovative approaches used in addressing exposure to occupational health hazards involving noise, ergonomics and chemicals.
2)WSH Case Studies -Accident Involving Working At Heights
Case Studies of Accidents Involving Working at Heights is the result of collective efforts of Ministry of Manpower and National WAH Safety Taskforce. Past concluded fatal accidents were compiled and categorised according to incident types for ease of reference. Through root cause analysis of these accidents, causes were examined and key learning points shared. The lessons and recommendations within will help you in implementing appropriate WSH measures at your workplaces to prevent work at heights injuries
3)WSH Case Studies -Working in and around Water
This case studies booklet aims to raise WSH awareness and reiterate the importance of strengthening WSH ownership at all levels.

In summary, the four learning points from the incident are:
1) Protect small-bore pipelines from accidental impact;
2) Provide a master shutdown button for safe and coordinated stoppage of gas filling;
3) Provide fire retardant clothing (FRC) to workers working with flammable substances; and
4) Plan and implement an effective emergency response
6)WSH Case Studies - Fatal Accident Involving Failure of a Tower Crane
This case studies showcased Learning Report involving Failure of Luffing Jib Tower Crane at Kajima Overseas Asia (Singapore) Pte Ltd’s Worksite Located at Tan Tock Seng Link.In summary, the two key learning points from this incident are:
1) Eliminate Risk of Entanglement between Erection Ropes and other Structures; and
2) Ensure Erection Ropes return to their Resting Position.
7)WSH Case Studies - Construction Industry
This compilation of case studies on fatalities in the construction industry depicts how the accidents occurred and provides valuable learning points on how they could have been prevented.
1. Falls from Height
2. Worker Struck by Fall
3. Electrocution
4. Worker Struck by/against Objects/Machines
8)WSH Case Studies - Marine Industry
Every year, more than 300 injuries befall our workers in the marine industry. Some workers who are severely injured face long roads to recovery or suffer from permanent incapacity. Some may never return home to their loved ones. It is our belief that no one should be injured at work. Everyone should go home safely every day, free from harm.
The Committee, comprising of business leaders from the marine sector, has put in a lot of effort to safeguard the workers. Although we have reduced the number of fatalities over the years, such incidents still happen, and sadly, some of these incidents are very similar in nature. Hence, the lessons drawn from these incidents are key to us in preventing the next incident from recurring. That is why we have pooled together our WSH expertise from various companies to compile these case studies.
This booklet is divided into various sections according to incident type for easy reference. The underlying causes of these accidents are carefully examined through root cause analysis. Make full use of this compilation, to share these cases at your company’s training or toolbox meetings on a regular basis and undertake study through each case, review its relevancy and context to specific workplace situations, and incorporate the lessons learnt where appropriate.
