Managing Peroxide Forming Chemicals in New York City

How to safely manage peroxide forming chemicals in New York City?

For many years, Columbia University has managed time-sensitive chemicals in accordance with New York City Fire Department (FDNY) requirements.  A revision to FDNY’s requirements, creating alignment with a National Fire Protection Association (NFPA) consensus standard, brings a change in FDNY’s enforcement strategy and, consequently, impacts all laboratories operating in New York City.  All chemicals in Table 1 must be dated at the time of opening and disposed of or tested for safety within 6 months.  Commonly cited chemicals are bolded and highlighted in red.
