An LPG inspector or examiner is a registered, approved professional who examines LPG tanks, cylinders, and pressure vessels to confirm they're structurally sound, correctly fitted, and safe to remain in service — the role that sits behind every certification, recertification, and compliance sign-off in the LPG industry. Without qualified inspection, there's no independent check on whether a pressure vessel is actually safe, which is exactly why the role is regulated and why the examiner's credentials matter as much as the inspection itself.
This is the pillar for our Inspection & Compliance content — for the closely related installation process, see LPG Tank Installation: A Step-by-Step Guide .
What Does an LPG Inspector Actually Do?
An LPG inspector's work spans the full lifecycle of a pressure vessel, not just a single point-in-time check.
New Equipment Inspection
Examining newly manufactured cylinders and tanks before they enter service, confirming they meet design and manufacturing standards.
Installation Verification
Checking that a completed installation matches approved engineering specifications and safety requirements.
Periodic Recertification
Re-examining vessels at required intervals throughout their service life. See our recertification guide for what this involves.
Incident or Damage Assessment
Inspecting vessels that have been involved in an incident, relocated, or show visible signs of wear or damage.
Decommissioning Assessment
Determining whether a vessel is fit to continue service or should be retired.
Cylinder Inspection vs. Tank/Pressure Vessel Inspection
While the underlying principles overlap, cylinder inspection and larger tank/pressure vessel inspection have some practical differences worth understanding.
LPG Cylinder Inspection
LPG cylinder inspection typically covers newly manufactured cylinders at the point of production, and again during periodic revalidation as cylinders move through their service life in circulation. Because cylinders are mass-produced, standardized, and widely distributed, this inspection often follows a structured, high-volume process.
Tank & Pressure Vessel Inspection
Tank and pressure vessel inspection is generally more individualized — each stationary tank or bullet is inspected in its installed context, considering site-specific factors like fittings, piping integration, and installation quality alongside the vessel itself.
Both fall under the broader scope of LPG inspection, but understanding the distinction helps when scoping out what kind of inspection a given project actually needs.
Why Regular Inspection Matters
LPG vessels operate under sustained pressure, holding a flammable gas, in conditions that can gradually affect their structural integrity — corrosion, fitting wear, and material fatigue don't always announce themselves visually. Regular inspection exists to catch these issues before they become safety incidents, rather than relying on a vessel "seeming fine" from the outside.
This is the core safety logic behind every LPG safety and compliance framework, and it's why inspection isn't a one-time event but a recurring requirement throughout a vessel's life.
Who Is Qualified to Perform LPG Inspections?
Inspection and certification must be carried out by registered, approved examiners — not general technicians or maintenance staff. In Kenya, this typically means an examiner registered with the relevant occupational safety authority, with specific technical competence in pressure vessel examination.
Registered & Approved Examiner
The person carrying out the inspection should have the appropriate registration, approval, and technical competence required for pressure vessel examination.
Our guide on Understanding the DOSH Inspector of Pressure Vessels covers this specific regulatory role in more depth.
What Happens During an Inspection
While the specifics vary by vessel type and inspection purpose, a typical LPG inspection generally includes:
Visual examination for corrosion, damage, or wear.
Fittings, valves, and safety relief system checks.
Pressure testing to confirm the vessel can safely hold its rated pressure.
Documentation review of prior inspection and certification history.
A pass/fail determination, with certification issued for vessels that meet requirements.
For a fuller breakdown of this process specifically for tanks due for renewal, see LPG Tank Recertification: What You Need to Know .
Inspection Across the LPG System Lifecycle
Inspection isn't limited to the tank itself — it intersects with several other stages of an LPG system's life.
Relocation
Moving a tank can affect fittings and structural integrity, requiring inspection before it returns to service.
Relocation & Transportation Guide →Evacuation
Safely emptying a tank is often required before major maintenance, inspection, or decommissioning.
LPG Gas Evacuation Guide →Recertification & Revalidation
The formal, recurring inspection cycle keeps a vessel legally and safely in service throughout its working life.
Recertification Guide →Why the Examiner's Credentials Matter
Not every inspection carries the same weight — an examiner's registration and approval status is what makes their sign-off legally and practically meaningful. This is one of the clearest E-E-A-T signals in the LPG industry: a certification is only as trustworthy as the examiner who issued it.
Always confirm an inspector's registration status before relying on their certification for a project.
Registration
Verify that the examiner has the relevant professional registration and approval.
Technical Competence
Confirm that the examiner has appropriate experience and competence in pressure vessel examination.

Frequently Asked Questions
What's the difference between an LPG inspector and an examiner?
In practice, the terms are often used interchangeably to describe a registered professional qualified to inspect and certify LPG vessels. Specific titles can vary by regulatory framework, but the underlying role — verifying safety and issuing certification — is the same.
How often should LPG cylinders be inspected?
LPG cylinders are inspected when newly manufactured and again at periodic revalidation intervals throughout their circulation life, in line with applicable regulatory requirements.
Can any technician perform an LPG tank inspection?
No. Only registered, approved examiners with specific pressure vessel qualifications can perform inspections that result in valid certification. General maintenance technicians aren't authorized to issue this certification.
What qualifications should an LPG inspector have?
An LPG inspector should be registered and approved by the relevant occupational safety authority, with demonstrated technical competence in pressure vessel examination specifically.
Does every LPG tank need to be inspected, even if it seems fine?
Yes. Structural issues like corrosion or fatigue often aren't visible without proper inspection, which is why periodic inspection is required regardless of how a vessel appears externally.
