Gas Monitoring is Essential for Safety
Protecting Workers from Invisible Hazards
Toxic gases. Oxygen deficiency. Explosive atmospheres.
These hazards are silent, fast-moving — and deadly.
In Australia, confined spaces and hazardous worksites continue to cause serious injuries and fatalities every year, often due to the failure to detect dangerous gases in time. According to Safe Work Australia, atmospheric risks contribute to a significant portion of confined space deaths, with workers sometimes rendered unconscious after just a few breaths.
That’s why real-time, reliable gas monitoring isn’t optional — it’s life-critical.
At Zokal, we deliver comprehensive gas monitoring solutions to safeguard workers in the harshest environments, ensuring compliance with Australian Work Health and Safety (WHS) regulations and industry best practice.

Why Gas Monitoring is Essential
Many workplaces — particularly confined spaces such as tanks, pits, silos, tunnels, and pipes — pose hidden atmospheric risks that cannot be detected by sight, smell, or touch.
The most common dangers include:
- Oxygen Deficiency:
Air with less than 19.5% oxygen can cause dizziness, unconsciousness, or death in minutes. - Toxic Gases:
Hydrogen sulfide (H₂S), carbon monoxide (CO), ammonia, and other gases can poison workers at extremely low concentrations. - Flammable or Explosive Gases:
Methane (CH₄), propane, or volatile organic compounds (VOCs) can ignite from a simple spark if concentrations are above the Lower Explosive Limit (LEL). - Oxygen Enrichment:
Too much oxygen (>23.5%) can turn a small spark into an uncontrollable fire hazard.
Without accurate atmospheric monitoring, workers may unknowingly step into deadly environments — with little or no chance of escape.

NSW WHS Regulations on Gas Monitoring
In New South Wales, under the Work Health and Safety (WHS) Regulation 2017, businesses must:
-
Conduct Air Monitoring
If there is uncertainty about airborne contaminant levels, employers must monitor the atmosphere to ensure it is safe for workers. -
Confined Space Entry Permits
Require documented atmospheric testing before and during entry operations. -
Limit Exposure to Hazardous Substances
Ensure that any airborne contaminants do not exceed the national exposure standards published by Safe Work Australia. -
Maintain Gas Detection Equipment
Ensure gas monitors are properly calibrated, maintained, and appropriate for the intended hazard.
