Gas monitoring is required whenever there is a risk of hazardous gases being present.
Confined space entry
(e.g. tanks, trenches, tunnels)
Groundworks and excavation
Brownfield or contaminated land development
Enclosed or poorly ventilated environments
If gases cannot be reliably detected by smell or sight, monitoring equipment is essential.

Supporting industry with trusted monitoring solutions since 1976.
Deep understanding of your challenges and environments.
Equipment and services designed to meet your specific needs.
Construction activities generate airborne hazards that can impact workers, contractors and surrounding environments. Monitoring helps identify exposure risks, maintain compliance and improve site safety.
Generated during cutting, grinding and drilling concrete, brick and stone materials.
Produced during cutting, sanding and shaping timber and engineered wood products.
Includes gypsum, cement and nuisance dust created during demolition and site works.
Helps assess off-site dust migration and environmental impact on neighbouring areas.
Monitoring ensures worker safety, legal compliance and data-led decision-making — reducing operational risk across every stage of your project.

Construction gas monitoring involves detecting hazardous gases on-site to protect workers and ensure compliance with safety regulations.
Common equipment includes:
Wearable single or multi-gas detectors
Portable monitors for perimeter boundary monitoring
RPE (masks and respirators), which must be fit tested
Air quality and dust monitors
Air quality monitoring is required when:
Dust or airborne contaminants are present
Workers may be exposed to harmful substances
Compliance with WELs is needed
Typical gases include:
Combustible gases (LEL)
Oxygen (O₂)
Carbon dioxide (CO₂)
Hydrogen sulphide (H₂S)
You should consider:
Type of gases present
Site conditions and location
Need for wearable vs portable vs fixed systems
Compliance requirements.
