AR or ID? A clear path through unsafe situations.

GasTrack helps engineers understand the hierarchy of unsafe situations under the Gas Industry Unsafe Situations Procedure — Immediately Dangerous, At Risk, Not to Current Standard, or no unsafe classification identified.

IdentifyAssessClassifyActRecord
The hierarchy

Assess against the applicable criteria.

Work through the hierarchy from highest risk down. Where a higher-risk classification is met, that classification takes precedence. The engineer must assess the specific situation against the current Gas Industry Unsafe Situations Procedure, manufacturer instructions and relevant requirements.

Start

Fault or concern identified on site

Assess the situation against the applicable criteria. Where a higher-risk classification is met, that classification takes precedence.

Decision

Immediate danger to life or property?

Gas escape, CO release, major flue failure, fire risk

Yes
ID

Immediately Dangerous

  • Disconnect the appliance
  • Make the installation safe
  • Do not leave in use
No
Continue to next check

Decision

Risk present that could become dangerous?

Incomplete combustion, minor flue defect, degraded seal

Yes
AR

At Risk

  • Leave with a written warning
  • Rectify promptly
  • May remain in use meanwhile
No
Continue to next check

Decision

Falls short of current standards, but no danger?

Older installation, superseded requirements

Yes
NCS

Not to Current Standard

  • Advise the customer
  • No disconnection required
  • Record the finding
No
Continue to next check
No higher-risk classification met
CLEAR

No AR/ID classification identified

  • No unsafe classification from the assessed criteria
  • Record the outcome and findings

Professional disclaimer

GasTrack is a decision-support tool. Classification must be based on the specific circumstances, current industry procedures, applicable regulations, manufacturer instructions and the competent engineer's professional judgement.

The four outcomes

What each classification means.

ID

Immediately Dangerous

A fault that poses an immediate threat to life or property. The appliance is disconnected, made safe and must not be used.

AR

At Risk

A fault that could become a danger. The appliance may remain in use with a warning, but must be rectified promptly.

NCS

Not to Current Standard

The installation falls short of current standards but presents no danger. Advise the customer and record the finding.

CLEAR

No AR/ID classification identified

No unsafe classification identified from the assessed criteria. Record the outcome and findings — this is not a certification of the installation.
