(Virtual Showroom) Diesel engine emissions remain a serious occupational health hazard, particularly in mining, construction, and industrial sectors. A major component of these emissions is Diesel Particulate Matter (DPM), a fine mix of harmful particles that, if not properly controlled, can pose significant health risks to workers.

What is Diesel Particulate Matter (DPM)?

Diesel Particulate Matter is produced during the combustion of diesel fuel and is made up of microscopic particles, including:

• Carbon soot, the core of DPM emissions.
• Ash and metallic abrasion particles from engine wear.
• Sulfates and silicates from fuel and lubricant additives.
• Elemental and organic carbon compounds that bind toxic substances like PAHs (polycyclic aromatic hydrocarbons).

These particles are so small that they can penetrate deep into the lungs and bloodstream, making them extremely hazardous to human health.

The Health Risks of DPM Exposure

Long-Term Health Risks:

• Cardiopulmonary diseases
• Chronic respiratory conditions
• Lung cancer
• Increased risk of heart attacks and strokes

Short-Term Health Effects:

• Headaches
• Dizziness and nausea
• Eye, nose, and throat irritation
• Difficulty breathing, especially in poorly ventilated environments

How to Reduce Exposure to Diesel Particulate Matter

To effectively reduce DPM exposure in the workplace, a layered hierarchy of controls should be adopted. These include:

1. Engineering Controls

• Diesel Particulate Filters (DPFs): High-efficiency, patent HJS DPF systems can remove up to 99% of particulate emissions.
• Low-emission engines: Upgrade to cleaner, compliant engine technologies that emit fewer harmful byproducts.
• Preventive maintenance: Well-maintained diesel engines emit fewer particles.
• Improved ventilation: Essential in underground or enclosed areas to disperse accumulated DPM.
• Filtered operator cabs: Protect machinery operators by filtering the air they breathe.

2. Administrative Controls

• Limit engine idling: Reducing idle time directly lowers emissions.
• Training & awareness: Educate workers on DPM risks and safe work practices.
• PPE (Personal Protective Equipment): Use certified respirators in high-risk zones where engineering controls are insufficient.
