A security guard is required to conduct fire extinguisher checks during their patrol. What should be included in their patrol report regarding these checks?

1. A list of all fire extinguishers that were *not* checked during the shift.
2. A photo of each extinguisher without any written description.
3. The date and time of the check, the location of each extinguisher, and its condition (e.g., charged, tagged, no obstructions).
4. Only a general statement that 'fire extinguishers were checked'.
