Working in confined spaces such as tanks, silos, sewers or pits presents complex hazards—oxygen deficiency, toxic gas buildup (e.g. CO or H₂S), and explosive atmospheres. Under Australian Standard AS 2865‑2009, atmospheric testing is mandatory before entry, with continuous monitoring required during work.
A multi-gas detector fitted with sensors for oxygen (O₂), lower explosive limit gases (LEL), carbon monoxide (CO) and hydrogen sulfide (H₂S) ensures full coverage. Devices must be intrinsically safe (e.g. meeting AS/NZS 60079 series), IP‑rated, and compliant for hazardous zones. Daily bump testing and monthly calibration are essential to remain compliant and accurate
The Industrial Multi Gas Detection Compound Monitor offers all the required features: real-time multi-gas monitoring, data logging, audible/visual alarms, intrinsic safety rating, and easy calibration. Ideal for site managers and safety supervisors, it streamlines permit-to-work compliance and allows teams to generate audit-ready atmospheric records.
Best practice: pair portable monitors with a structured safe‑entry procedure—ideal ventilation, standby person, pre‑entry risk assessment, and authorised entry permits as required by AS 2865.
2. Confined Space Gas Monitoring: Choosing the Right Equipment
Selecting the correct gas detector for confined‑space work is a critical safety decision. Choose units that monitor at minimum: O₂, CO, H₂S, and LEL. Additional sensors may be needed depending on the specific environment. The detector must be intrinsically safe and compliant with AS/NZS 60079.29.2 for flammable and toxic gases
The Industrial Multi Gas Detection Compound Monitor supports versatile sensor sets, real-time data display, data logging for compliance, plus dual alarms and rugged design suitable for IP67 environments. Its compatibility with AS 2865 safe-entry workflows makes it a reliable choice.
Beyond hardware, effective confined-space gas-monitoring programs require:
-
Daily bump‑testing before each use.
-
Quarterly calibration as per manufacturer guidelines.
-
Training for operators on reading alarms and gas thresholds.
-
Written procedures tied to entry permits and rescue readiness
3. Confined Space Compliance in 2025: A Practical Safety Guide
As enforcement tightens in 2025, businesses in Australia must demonstrate rigorous compliance with WHS laws and AS 2865 protocols. Inspectors commonly check for:
-
Documented atmospheric testing before and during entry.
-
Calibration logs and bump‑test records.
-
Operational detectors used correctly during entry and exit cycles.
The Industrial Multi Gas Detection Compound Monitor simplifies these compliance demands: it documents readings, time-stamps and stores event logs which can be exported for audits. With built‑in warnings at thresholds (e.g. 5‑10 % of LEL or O₂ outside 19.5‑23.5 %), it's aligned with AS 2865’s safety limits
Deploy with these user best practices:
-
Pre‑entry risk assessment identifying gases present.
-
Controlled ventilation and purge until safe.
-
Use of detector within breathing zone.
-
Stand‑by person communication and immediate evacuation upon alarm.
By integrating this detector into your Safe Work Method Statements (SWMS) and site procedures, facilities can reduce incidents, improve audit readiness and ensure worker safety.
4. Distillery Safety: Why Multi-Gas Detectors Are Essential
Distilleries generate hazards including ethanol vapors, carbon dioxide (CO₂) and oxygen depletion during fermentation and storage processes. Ethanol is highly flammable and heavier than air, seeking low‑lying and enclosed zones. CO₂ can displace oxygen and cause asphyxiation.
Installed fixed monitors alone are not enough. Every distillery must equip workers with a portable multi-gas unit that can detect ethanol/LEL, CO₂, O₂ and optionally CO or H₂S depending on processing. The Industrial Multi Gas Detection Compound Monitor is built for this: rugged, sensor-configurable, with audible and visible alarms, and full data logging for safety protocols.
Portable detectors paired with fixed ambient detection ensure that fermentation tanks, bottling lines, storage areas and confined maintenance zones are monitored effectively.
5. Implementing Gas Safety in Craft Distilleries
Target keywords: “craft distillery safety Australia”, “explosion proof gas detector ethanol distillery”
Growing numbers of Australian craft distillers are exposed to increased risks from flammable ethanol vapors and confined-space work. Flammable gases may accumulate in fermenters, stills, loading areas, or low-lying corners.
Implement a layered gas detection strategy:
-
Fixed ethanol/LEL detectors in production zones.
-
Portable multi-gas monitors during entry or maintenance.
-
Audible and visual alerts at entry points to high-risk zones.
The Industrial Multi Gas Detection Compound Monitor is suitable for both mobile and confined‑space applications. It offers explosion‑proof design, high-visibility alarms and supports standard permit entry systems. Maintaining logs helps prove compliance with WHS and licensing regulations.
6. Distillery Compliance: Protecting Workers & Property
Australian distilleries must comply with WHS regulations and local licensing laws for flammable substances, including storing over 120 L of Class 3 PGII ethanol requiring licensing and rigorous safety systems.. Insurers also demand safety evidence: gas-monitoring, training and emergency response plans.
Essential compliance actions:
-
Continuous detection of ethanol/LEL, CO₂, oxygen levels.
-
Portable detector carried by staff entering confined or high-risk zones.
-
Documented training, procedures, and calibration/bump-test logs.
-
Linking detection alarms to shutdown or ventilation systems, if required.
With built-in alarm thresholds and event logging, the Industrial Multi Gas Detection Compound Monitor can be paired with ventilation and shutdown logic to enhance safety and meet compliance standards.
