Gas Installation Inspection at Grange 80 Condo, Orchard
📍80 Grange Road | 🏨 Condo
As part of the regulatory requirements under the Gas Act 2001 and Gas (Supply) Regulations, a comprehensive gas installation inspection was recently carried out at Grange 80, a private residential condominium situated in the Orchard / Tanglin district of Singapore. This inspection is part of the mandated compliance to ensure the inspection, maintenance, repair, and renewal of gas installations across residential properties.
Homeone’s certified inspection team, led by a Licensed Gas Service Worker (LGSW), conducted the checks using the Honeywell BW Max XT II multi-gas detector, a highly accurate device designed for detecting gas hazards in confined spaces. The goal of this inspection was to identify any potential gas leaks, assess the condition of the installation components, and take necessary steps to ensure residents’ safety and system compliance.
✅ Purpose of the Gas Installation Inspection
This inspection was conducted in accordance with the Gas Act 2001 and the updated Gas (Supply) Regulations. These regulations designate property owners as responsible for:
- Inspecting, maintaining, repairing, and renewing gas installations.
- Engaging a Licensed Gas Service Worker (LGSW) or Professional Engineer (PE).
- Submitting a Certificate of Fitness (COF) confirming the gas system is safe and compliant.
At Grange 80 Condominium, located in the Orchard/Tanglin area, Homeone’s LGSW-supervised inspection team conducted thorough checks from Level 1 to Level 10. The inspection used the reliable Honeywell BW Max XT II — a portable, confined-space-ready multi-gas detector capable of monitoring up to four gas hazards simultaneously.
The primary objective was to detect any gas leaks or hazards, ensure safety compliance, and recommend prompt action for necessary gas installation maintenance, repair, or renewal.

⚠️ Key Issues Identified and Their Risks
-
Gas Leaks
- Definition: A release of combustible gas into the air due to faulty seals, joints, or corroded pipes.
- Dangers:
- Highly flammable, posing fire and explosion risks.
- Health hazard in enclosed spaces (nausea, dizziness, or suffocation).
- Levels above 100ppm are critical and require immediate action.
-
Missing Syphon Leg
- Definition: A syphon leg is a short, downward vertical extension pipe installed at the lowest point of a gas installation to collect and remove condensate.
- Non-Compliance: Violates SS 608:2024, Section 3.40 – Syphon Leg, which requires installation at the lowest point of the gas line for condensate collection and removal.
- Dangers:
- Absence of a syphon leg can lead to condensate accumulation, causing blockage, corrosion, or gas backflow.
- Increases risk of gas odor leakage and system instability.
- Fails to meet statutory safety and compliance standards.
-
Rusty Elbow Fitting
- Definition: A bent joint in gas piping showing signs of corrosion.
- Dangers:
- Rust weakens metal, making it prone to cracking or leaking.
- Indicates accelerated pipe aging and may lead to future failures.
🛠️ Recommended Next Steps
Based on the findings from the gas installation inspection, the following steps are required to ensure safety compliance and prevent operational risks:
🔧 Immediate Repairs:
- Address all gas leaks identified during inspection.
- Install missing syphon legs where absent.
- Replace or refurbish any rusty elbow joints.
👷 Engage a PE or LGSW:
- Conduct a post-repair re-inspection by a Licensed Gas Service Worker or Professional Engineer .
- Submit a Certificate of Fitness (COF) to SP PowerGrid within 30 days of inspection.
