Start from the equipment list that names each laser and the room it sits in, then check that the room construction, the power and emergency shutoffs, the interlocks, the exhaust, and the fire protection drawn by each discipline serve the same rooms. AI can flag conflicts; the laser safety officer, the engineers, and the authority having jurisdiction decide compliance.
What does NFPA 115 cover?
NFPA 115 is the Standard for Laser Fire Protection. NFPA’s page states that the standard provides minimum fire protection requirements for the design, manufacture, installation, and use of lasers and associated equipment, and contains criteria for training and responding to fire emergencies involving lasers.
NFPA’s official NFPA 115 page identifies the 2020 edition as current when checked on October 11, 2026. Confirm the edition, local amendments, and project scope that actually govern the work. The publisher’s newest edition does not establish local adoption.
Laser rooms usually sit inside laboratories covered by the NFPA 45 guide or fabrication facilities covered by the NFPA 318 guide, and health care lasers inside facilities covered by the NFPA 99 guide. NFPA 115 also covers training and emergency response, which are not drawing questions. Record which lasers and rooms are in scope before comparing.
Gather the laser equipment list and room drawings
Collect the laser and equipment list with room assignments, the floor plans and enlarged laser room plans, the wall, door, and window details for each room, the electrical drawings with laser power and emergency shutoffs, the interlock and controls drawings, the exhaust and ventilation drawings for fume or process exhaust, the fire alarm and suppression drawings, and the specifications.
Laser vendors often issue room requirements separately. Upload them with the building set so the room drawings can be compared with what the equipment needs.
Follow each laser room through the disciplines
| Review question | Sources to compare | Decision to record |
|---|---|---|
| Laser rooms | Equipment list, floor plans, room names | Confirm each laser and its room are named the same in the equipment list and on every plan. |
| Enclosure and openings | Door and window details, wall types, enlarged plans | Check that doors, windows, and viewing panels into each laser room match between the plans and details. |
| Power and shutoffs | Electrical drawings, panel schedules, controls | Find laser power circuits and emergency shutoffs shown on one discipline’s sheets but not the other’s. |
| Interlocks | Controls drawings, door hardware, specifications | Match door interlocks and warning devices with the door hardware and controls documents. |
| Exhaust | Mechanical drawings, equipment data, specifications | Ask the engineer to confirm the fume or process exhaust drawn for each laser that the vendor data calls for. |
| Fire protection | Fire alarm and suppression drawings, room plans | Identify laser rooms whose detection or suppression differs between the fire protection drawings and the narrative. |
These questions come up in laboratory, higher education, and manufacturing projects; the electrical drawing checklist helps track the shutoff and interlock questions.
Example: a laser room moved down the corridor
Hypothetical example. A university research building moves a high-power laser lab to a different room during design. The equipment list and architectural plans show the new room, while the electrical drawings still place the emergency shutoff and the door interlock at the original room.
The equipment list and architectural plans move the laser lab to a new room, but the electrical drawings still show its emergency shutoff and door interlock at the original room. Please confirm the controls for the new room and coordinate the electrical and door hardware documents.
The electrical engineer relocates the shutoff and interlock and the hardware schedule follows. Compliance is decided by the laser safety officer, the engineers, and the authority having jurisdiction.
Review a laser facility with Groundbook
Upload the current project PDFs and relevant specifications to Groundbook. Identify the governing issues and add the applicable NFPA 115 reference from a copy you are licensed to use, where the license permits uploading it. State the edition, amendments, review area, and known exclusions in your instructions.
Compare the laser equipment list, floor and enlarged plans, door and window details, electrical drawings, interlock and controls drawings, exhaust drawings, fire alarm and suppression drawings, vendor room requirements, and specifications. Flag laser rooms, openings, shutoffs, interlocks, exhaust, and fire protection that differ between sources. Use the supplied NFPA 115 edition where applicable and cite both sources.
Groundbook links each potential finding to the sheets involved and the reference you uploaded.
Document review does not classify a laser, assess beam hazards, or approve the facility. Those decisions remain with the laser safety officer, the engineers, and the authority having jurisdiction.
