Dust Hazard Analysis
Dust Hazard Analysis (DHA) is a professional risk assessment process used to identify and analyse potential workplace hazards caused by combustible dust. The likelihood and impact of workplace dust hazards are determined to develop and implement effective risk mitigation measures.
To identify potential dust hazards in the workplace, DHA involves considering potential locations around the workplace such as storage areas, operational areas, and handling facilities where combustible dust is present or can accumulate. Depending on the potential severity and frequency of the dust hazard, companies can develop safety measures and implement effective risk management plans.
At QES Consultancy, we help businesses conduct effective DHA that aligns with the business requirements and objectives.

What is Dust Hazard Analysis (DHA)?
Dust Hazard Analysis (DHA) is a systematic review of combustible dust in the workplace. DHA includes identifying combustible dust hazards and evaluating potential scenarios to support the development of effective risk mitigation measures. It includes considering potential locations around the workplace such as storage areas, operation areas, and handling facilities. In this way, potential fires and dust explosions in the workplace can be foreseen and reduced.
Hazards from combustible dust, such as fire and explosions, may be present in many industries. That’s why DHA is important in building a safe workplace for employees mitigating the risk.
Process of DHA
Identify Dust Hazard Areas
Identify all areas, processes, and activities in the workplace where combustible dust is present or may be generated.
Assess Potential Consequences
Determine the possible consequences of combustible dust hazards, such as fire, explosion, equipment damage, or injury.
Evaluate Likelihood of Occurrence
Assess the likelihood or frequency of dust-related incidents occurring based on operational conditions and exposure levels.
Develop Control Measures
Based on the severity and likelihood of the hazard, recommend appropriate control measures to prevent, reduce, or mitigate combustible dust risks.
DHA in Singapore
According to SS 667:2020 (Code of Practice for Handling, Storage, and Processing of Combustible Dust), workplaces with combustible dust hazards should conduct a dust hazard assessment carried out by a competent person. In 2025, The Ministry of Manpower (MOM) also published enhanced safety measures for combustible dust. This highlights the importance of dust hazard analysis in workplaces.

FAQs on Dust Hazard Analysis
Four types of combustible dusts such as metals, chemicals, plastics, and organic matter are included as they can ignite and cause fire or explosion when oxidized.
In Dust Hazard Analysis, we will check the safe range at the workplace with combustible dust and identify the likelihood and consequences of fire and explosion. Then, we will also suggest safety measures depending on the frequency and severity of potential hazards.
Dust Hazard Analysis is important for organizations to store, handling or managing combustible dust to ensure workplace safety and health, preventing fire and explosions in the workplace. Based on the amount of combustible dust, the company may be legally required by MOM to conduct DHA.
Organizations that manufacture, transport, handle, store, or manage a certain amount of combustible dust require Dust Hazard Analysis.
Common combustible dusts including organic dusts such as sugar and flour, metal dusts such as iron and chemical dust such as plastic and rubber cause potential fire and explosion in the workplace.
Dust in the workplace can cause fire, explosion, occupational health issues, and regulatory compliance concerns.
Dust Hazard Analysis identifies the frequency and impact of potential fire and explosions from combustible dust and develops safety measures to reduce dust hazards in the workplace.
Combustible Dust Testing examines if dust is combustible and analyses its characteristics while Dust Hazard Analysis identifies and analyses potential dust hazard frequency and impact along with suggestions for safety measures.
