Questions

PSSR readiness FAQs.

What is the main PSSR document?

The central PSSR document is the Written Scheme of Examination. It identifies relevant parts of the pressure system, the nature of examination and the examination intervals.

Do all compressors need the same PSSR approach?

No. The requirement depends on the system configuration, pressure, volume and use. A competent review should confirm whether the system needs a written scheme and what parts must be examined.

Why should PSSR be planned early?

Pressure-system work may need isolation, cooling, draining, access preparation or coordination with maintenance contractors. Leaving it until the due date can create avoidable downtime.

Book an inspection

Need a clear compliance report?

Send the equipment list, site postcode and any due dates. City Inspection Services will confirm scope, availability and the most sensible inspection schedule.
