Gas Leak Detectors - Welding and Fabrication

Portable gas leak detectors used during marine welding, hot work, tank entry, and ship repair to detect flammable gases, oxygen deficiency or enrichment, and toxic gases. They support atmospheric testing before and during fabrication activities.

ProShipWorks provides end-to-end support to source and supply Gas Leak Detectors for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval

Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.

Applicable Standards & Certification	Common requirements include IEC 60079-0 and IEC 60079-11 for hazardous-area equipment, IEC 60079-29-1 for flammable-gas detectors, IEC 60079-29-2 for selection and use, and EN 45544 for workplace toxic-gas measurement. ATEX and IECEx certification may apply.
Class Approval	Classification approval is model- and installation-specific. Marine-suitable units may have approvals or acceptance from DNV, ABS, Lloyd's Register, Bureau Veritas, or ClassNK. Verify the current certificate and hazardous-area rating with the manufacturer and vessel class.

Installation, Maintenance & Safety Information

Installation Notes	Use a calibrated detector suitable for the gases expected. For confined spaces, use the approved sampling hose and pump, test remotely before entry, and sample at multiple elevations because gases have different densities. Confirm sensor configuration and hazardous-area certification before use.
Maintenance Tips	Perform a bump test before each shift or according to the manufacturer's procedure. Calibrate at the specified interval using certified gas, keep sensor openings clean, inspect filters and sampling hoses, and replace sensors, batteries, or calibration gas before expiry.
Safety Notes	Do not use a detector as a substitute for ventilation, isolation, gas freeing, or a permit-to-work system. Test oxygen, flammable gases, and toxic gases before and continuously during hot work where required. Keep ignition sources controlled and evacuate immediately on alarm.
