NFPA 10, 6.3.2.2 Seals or
Tamper Indicators
At the time of the maintenance, the tamper seal
of rechargeable fire extinguishers shall be removed by operating the pull pin or
locking device. After the applicable maintenance procedures are completed, a new
tamper seal shall be installed.
The code section needs to include:
Tamper seal shall indicate the date of the tamper seal’s
installation.
Having a dated seal ensures the seal was removed during the
annual maintenance as required. Otherwise, it is impossible to know if the old
one was just left there and who knows how much else was not done...
