Start from the business hotel guest floor model (free sign-up). A hotel or inn is item (5)イ of Table 1 of Japan’s Fire Service Act Enforcement Order. In this article, on the members’ guest floor of a business hotel (the 5th floor, twelve guest rooms), your AI checks the fire equipment. The building is taken as six storeys of this floor, 2,251.44 m² in all, fire-resistant with flame-retardant finishes. It ran the same tools an AI calls over MCP. Every figure and number below comes from that run.

1. The guest floor

Plan of the guest floor with the extinguishers and the hydrant
Six guest rooms on each side of a central corridor, a stair at each end, two extinguishers and an indoor fire hydrant in the corridor
  • A floor of 31.8 × 11.8 m = 375.24 m² on its outer walls’ centre lines holds six guest rooms on each side of a central corridor 1.8 m wide, and a stair at each end.
  • In one change (edit_space) your AI puts two extinguishers and an indoor fire hydrant on the corridor’s north wall. check_space finds nothing.

2. The automatic fire alarm

  • Item (5)イ needs an automatic fire alarm whatever its total floor (Article 21(1)(i)イ).
  • Your AI counts thirteen smoke detectors (ceiling 2.5 m): one in each guest room and one in the corridor. The corridor is 25.2 m long, one detector for each 30 m of walk.

3. The extinguishers

  • A hotel of 150 m² of total floor or more needs them (Article 10(1)(ii)イ). The units are the total floor divided by 100 m² (Enforcement Regulations Article 6): 22.51 for the building.
  • For this floor’s share your AI counts 3.84 units, on the floor as drawn (384 m²). Two extinguishers of three units give six.
  • From anywhere on the floor the nearest extinguisher is a walk of 12.55 m, within 20 m (Article 6(6)).

4. The indoor fire hydrants

  • Item (5) needs them from 700 m² of total floor (Article 11(1)(ii)); three times, 2,100 m², in a fire-resistant building with flame-retardant finishes, twice, 1,400 m², in one without (Article 11(2)).
  • At 2,251.44 m² it needs them either way.
  • From a No. 1 hydrant (25 m) halfway along the corridor, the farthest point of the floor is 18.05 m: one reaches.

5. The exit lights

  • Item (5)イ needs exit lights and passage lights on every floor (Article 26(1)(i) and (ii)).
  • No guest room sees a stair’s door, so none may be left out (Regulations Article 28-2). From a guest room’s farthest point to a stair is a walk of 17.97 m.

6. Flame-retardant curtains and carpets

  • Item (5)イ is a building whose curtains and carpets must be flame-retardant (Order Article 4-3(1)): curtains, fabric blinds, carpets and the like with flame-retardant performance (Article 4-3(3)).

7. Using the check

  • Draw your hotel’s floors (from a PDF drawing or photos as well), and tell your AI the storeys, the total floor, the structure and finishes, and the ceiling height.
  • Not checked: the sprinklers, the escape devices, the emergency alarm, the other floors (the lobby, a restaurant) and the local fire department’s guidance.
