Ensure a safe breathing environment in your workplace with METS Lab’s specialized Inhalable and Respirable Dust Monitoring services, conducted in compliance with MDHS 14/3:2000 – the UK HSE-approved method for sampling and analyzing airborne particulate matter in occupational settings
What is MDHS 14/3:2000?
MDHS 14/3 (Methods for the Determination of Hazardous Substances) is the Health and Safety Executive’s authoritative guidance for the gravimetric determination of inhalable and respirable dust fractions in workplace air. This method outlines the sampling procedures, flow rates, and filter media to accurately assess exposure to harmful airborne particulates that can deposit in different regions of the respiratory system.
- Inhalable dust: Particles that can enter the nose and mouth during breathing.
- Respirable dust: Finer particles that penetrate deep into the lungs and alveolar region.
Why Monitor Dust in the Workplace?
Occupational exposure to airborne dust can lead to serious health conditions such as:
- Occupational asthma
- Chronic Obstructive Pulmonary Disease (COPD)
- Silicosis
- Pneumoconiosis
- Lung cancer (with prolonged exposure to carcinogenic dust)
Regular monitoring ensures compliance with national and international regulations
Our Dust Monitoring Services Include:
- Personal sampling using IOM samplers (for inhalable dust)
- Cyclone samplers for respirable dust collection
- Filter-based gravimetric analysis as per MDHS 14/3 protocol
- Time-weighted average (TWA) exposure calculations
- Task-based and full-shift assessments
- Rectangle 3, TextboxCustomized sampling strategy for indoor and outdoor environments
