Most Common FDNY Lab Violations

There are two types of violations that the FDNY issues for unsafe lab conditions. A Violation Order (VO) is an order relating to imminent fire safety hazards (e.g. blocked egress). A re‐inspection will occur on or soon after the correction period that is listed in the violation.

  • If the violations are completely corrected, the FDNY will dismiss the VO
  • If the violations are partially corrected, the reccipient of the violation (generally the lab Principal Investigator) will have to finish correcting all items on or before the date stipulated on the violation.
  • If the violations are not corrected on time, the recepient of the violation can receive a summons.

A Notice of Violation (NOV) is issued for conditions that do not represent an imminent hazard. An NOV must be corrected generally within 30 days. If you receive an NOV, you will not need a re‐inspection. Instead, once you have corrected the condition(s), you must submit proof of correction, such as affidavits or photographs, to the FDNY Enforcement Unit. The correction affidavit form is included in the NOV and can be mailed before the end of the correction period. If you do not correct the violation within 30 days, you must attend an Environmental Control Board (ECB) hearing.
