Trained crew for water-borne disease, confined space and gas detection
ALPHA & OMEGA TRINITY PTE. LTD. (UEN 201215586K) keeps WSH-style certificates on file for roof tanks, manholes, ejector pits and pump rooms. This page lists the named crew from certificate filenames (pack filed 30 August 2026) so FM, MCST and UPS panels can score licensed-and-trained lines. Course codes, certificate serials and expiry dates are on the scans — we do not invent them here. Ask admin@aot.com.sg for copies with your RFQ.
