Understanding Combustible Dust Risks in Industrial Facilities

Combustible dust can be generated during a wide range of industrial processes, including powder handling, plastics processing, and metalworking. Understanding how dust accumulates and ignites is the first step towards creating a safer and more compliant workplace.

Stars Engrg Tuas Explosion

The 2021 Tuas industrial explosion highlighted the devastating consequences that combustible dust can pose when hazards are not properly identified and controlled. While often overlooked, dust generated during manufacturing processes can accumulate and create significant fire and explosion risks.


The Hidden Impact of Oil Mist in CNC Machining Environments

Oil mist is a common by-product of high-speed machining operations and is often overlooked as a workplace contaminant. Over time, airborne oil mist can affect air quality, increase housekeeping requirements, and lead to residue buildup on machinery and surrounding work areas.



Regulations & Standards (SS667, MOM, NFPA)

Industrial air filtration and extraction systems in Singapore are governed by a combination of local regulations and international standards. These requirements are designed to ensure workplace safety, reduce fire and explosion risks, and maintain operational reliability.

Understanding how these standards apply to your facility is critical — not just for compliance, but for protecting your people, equipment, and production processes.

SS667 – Combustible Dust Safety

In Singapore, SS667 provides local guidance on the safe handling, storage, and processing of combustible dust in industrial environments. It is relevant to facilities where fine particulate materials can pose a fire or explosion risk.

It applies to:

  • Dust-generating manufacturing processes

  • Powder handling and transfer systems

  • Filtration and dust collection systems

  • Areas where dust accumulation may occur

Key considerations:

  • Identification of combustible dust hazards

  • Prevention of dust accumulation in equipment and ducting

  • Proper design of dust collection systems

  • Implementation of explosion protection measures

In practice, facilities handling combustible dust must ensure systems are designed to minimise ignition risk and safely manage dust hazards.

MOM Workplace Safety & Health (WSH) Requirements

The Ministry of Manpower (MOM) enforces workplace safety regulations across all industrial sectors in Singapore.

For air quality and extraction systems, this includes:

  • Controlling exposure to hazardous dust, fumes, and mist

  • Ensuring safe working environments for employees

  • Maintaining systems to prevent equipment failure or incidents

Common compliance gaps:

  • Inadequate extraction at source

  • Poor system maintenance

  • Lack of proper filtration or airflow control

Non-compliance can lead to fines, operational disruption, or safety incidents.

NFPA Standards (Explosion & Fire Protection)

For facilities handling combustible dust or flammable particles, NFPA standards are critical.

Relevant standards include:

  • NFPA 68 – Explosion Venting

  • NFPA 69 – Explosion Prevention Systems

  • NFPA 652 – Fundamentals of Combustible Dust

These standards address:

  • Explosion risk assessment

  • Venting and suppression system design

  • Isolation of hazardous processes

  • Safe handling of combustible dust

In many industrial environments, explosion protection is not optional — it is a requirement.
