The Cambridge Fire Department strictly follows the Mass. Fire Prevention Regulations and has not approved previous requests for fire/explosion related activities listed below.

Game and Ride related activities:

  • Climbing walls and inflatable games in which a participant could free fall more the 4 feet, which is what triggers the OSHA requirements for Fall Protection. Refer to the inflatable guidelines

  • Tight rope walking, Slacklining, Aerial silk, etc.
