Strengthen your Risk Assessments. Let the WSH Gatekeeper™ extract the truth from your manual Method Statements and map every potential hazard into a high-fidelity and WSH-compliant RA report for professional review and sign-off in minutes.
Start Assessment NowWe ingest your full operational scope. No matter how messy the notes, the WSH Gatekeeper™ identifies the project scope.
“Project: HDB Hub Solar PV Installation. Work scheduled for 8 June. Scope includes site mobilization and transporting all PV modules to the rooftop via service lift where possible. Ground crew will deploy a 50T mobile crane to hoist panels from the loading bay; crane setup location is tight and directly adjacent to a high-traffic public pedestrian walkway — physical barricades required and a banksman assigned at all times. Ground is slightly uneven near the laydown area; outriggers must be fully extended on timber pads per manufacturer spec. Stop all lifting if wind speed exceeds 20 knots. Roof team receives panels and mounts using full body harnesses, 100% tie-off on certified lifelines; monitor for heat stress during peak hours. Electrical team performing DC/AC terminations and cable testing per SS 638; mandatory LOTO procedure before any live work.”
The WSH Gatekeeper™ engine cross-references the project scope against the latest Singapore ACOPs. Lifting, WAH, and Electrical themes are detected — severity logic locks before the Safety Analyst swarm runs.
Extracted Project Profile
After triage locks severity baselines, a 5-agent distributed network interrogates your method statement in parallel. Hazard classification, ACOP mapping, and risk matrix scoring run through gated checkpoints before the Fiduciary Auditor synthesizes a WSH-compliant assessment ready for professional sign-off.

Initialize Your WSH Risk Assessment“We didn't just build an AI agent; we built a rigorous logic engine. If the Code of Practice sets a hazard's Severity at 5, that baseline Severity stays locked at 5. We don't fudge the numbers to make the risk assessment look good. Instead, our system forces users to lower the Risk Level by driving down Likelihood through verified control measures.”
