What must a temporary permit holder do if the duration of their operation exceeds the initial permit?

When a temporary permit holder's operation exceeds the duration specified in the initial permit, the appropriate course of action is to apply for a permit extension. This is necessary because permits are issued for a specific timeframe, and extending the operation without an updated permit could potentially violate regulations and lead to penalties or legal issues. By applying for an extension, the holder ensures compliance with local laws and maintains safety standards related to the operation of non-flammable compressed gases.

Continuing the operation without change could result in unauthorized activity since the original permit may no longer be valid past the specified period. Changing the operation type would typically require a new permit, not merely an extension. Informing local authorities may be part of the process but does not fulfill the requirement for a valid permit to operate legally. Thus, obtaining a permit extension is the necessary and responsible step to take in this situation.
