  • Improper/degraded gas connections have the potential for life-threatening consequences.
  • The Department inspects buildings for gas-related development and complaints
  • Approximately 19,000 buildings were inspected from Aug 2016 – Jun 2017
  • Collaboration between DOB and gas utilities is critical for implementing safety measures and quality control

Gas Utility Notifications to DOB

Periodic DOB – Utilities meetings are maintained to:

  • Clarify policies and procedures
  • Enhance procedural coordination
  • Define notification and information requests, reports, and frequency
  • Establish quality controls

DOB determines the classification of high risk in two ways:

  • The gas-related condition is recognized as critical and requires immediate mitigation by the Utility and notification to DOB.
  • Triage of inspection notifications using text analysis
  • Utility notes which contain text associated with a high risk (i.e. illegal, bypass, defective, etc.) are prioritized for inspection.

Analysis of High-Risk Notifications

DOB received roughly 12,000 gas notifications from August 2016 to June 2017, and determined that approximately 10% should be considered high-risk to City residents.
