The Ultimate Guide to Top 10 Workplace Hazards in Singapore: Manufacturing & Construction Focus (2025)

Introduction: The State of Workplace Safety in Singapore

Singapore’s workplace safety landscape presents a stark paradox in 2025. While achieving a record-low major injury rate of 15.9 per 100,000 workers, the nation witnessed a troubling resurgence in fatalities – 43 deaths in 2024, up from 36 in 2023 10. This translates to a fatality rate of 1.2 per 100,000 workers, moving away from the historic sub-1.0 rate achieved in 2023. The construction, manufacturing, and marine sectors remain critical areas, accounting for 80% (34 deaths) of all workplace fatalities 10. Within manufacturing, food production and metalworking are particularly high-risk subsectors, while larger-scale construction projects saw deaths nearly double from 7 (2023) to 13 (2024) 610. These statistics underscore an urgent truth: traditional safety approaches need reinforcement with technology, cultural transformation, and sector-specific strategies. This comprehensive guide dissects the top 10 hazards confronting Singapore’s industrial backbone, providing actionable, regulation-compliant mitigation strategies to protect your workforce and operational viability.

1. Falls from Heights: Construction’s Perennial Killer

The Harsh Reality: Falls accounted for 20 construction deaths in 2024, cementing their status as Singapore’s deadliest hazard 10. Investigations revealed systemic failures: 9 fatal fall sites lacked basic safety systems, triggering MOM stop-work orders. Beyond fatalities, falls from height contributed significantly to the 587 major injuries recorded nationally 10.

Root Causes in Singapore Context:

• Unprotected edges/openings in high-rise facade work
