Dahlcore Security Guard Services provides certified hot work watch across all five NYC boroughs, Long Island, and New York State. We deploy FDNY Certificate of Fitness–credentialed personnel to monitor welding, cutting, brazing, grinding, torch work, and soldering on construction, renovation, and industrial sites — with continuous monitoring during operations, the required post-operation watch for smoldering materials, and documented patrol logs, in compliance with NFPA 51B and the NYC Fire Code. Since 2018, New York contractors and building owners have relied on Dahlcore for compliant hot work coverage, with same-day and 24/7 dispatch, subject to availability.
What Is Hot Work Watch?
Hot work watch is a specialized fire-safety service required during operations that produce heat, sparks, or open flame — welding, cutting, brazing, grinding, torch work, and soldering. Under NFPA 51B, a qualified fire watch must remain on-site during all hot work and for a minimum of 30 to 60 minutes after operations end, to catch smoldering materials and delayed ignition. It’s different from a general fire watch.
Hot Work Watch vs. General Fire Watch
- Hot work watch — required during active spark- or heat-producing operations, regardless of whether suppression systems work
- Covers the operation and the mandatory 30–60 minute post-operation period
- General fire watch — required when a building’s alarm, sprinkler, or suppression system is impaired or out of service
- Both can be required on the same site at the same time

The spark you see isn’t the one that starts the fire
Most hot-work fires start after the torch is off — smoldering inside a wall or ceiling. That’s why NFPA 51B mandates a post-operation watch, and why Dahlcore stays until the danger window closes.
Why New York Contractors Choose Dahlcore
FDNY-credentialed, NFPA 51B–driven, and fully documented — Dahlcore hot work watch keeps your project safe and your permit conditions met.
FDNY Certificate of Fitness Personnel
A NYC hot work watch must be performed by a Certificate of Fitness holder. Dahlcore matches guards to the assignment with the appropriate C.O.F. — including the fire guard for hot work (F-02) and torch operations (G-60) credentials — all under our NYS Security Guard Act (Article 7-A) license.
Veteran-Owned, Held to Higher Standards
Dahlcore is veteran-owned and operated, and the owner personally manages guards in the office and in the field. Officers are held to law-enforcement and military standards — disciplined and dependable on every watch.
NFPA 51B Protocol
Pre-work checks of the 35-foot fire-safe radius, continuous monitoring with a clear line of sight during operations, and the required 30–60 minute post-operation watch for hidden embers.
Audit-Ready Documentation
Every assignment produces a completed patrol log, a post-operation sign-off record, and an incident report if a hazard is found — supporting FDNY compliance and insurance. Certificates of insurance are available on request.
Where Hot Work Watch Is Needed
How Dahlcore Conducts Hot Work Watch
Our protocol follows NFPA 51B guidelines and FDNY site requirements across every phase of the work.
Pre-Operation Assessment
The guard inspects the area, verifies removal or shielding of combustibles within the 35-foot NFPA 51B radius, confirms extinguisher access, and notes emergency contacts and exits.
Continuous Monitoring
During all hot work, the guard keeps an unobstructed line of sight to the work zone, watches for spark travel and heat migration, and logs activity at intervals.
Post-Operation Surveillance
After work stops, the guard holds the required 30–60 minute watch (longer for complex or concealed spaces), checking for smoldering and hidden ignition sources.
Documentation
A completed patrol log, a post-operation sign-off, and an incident report if needed — formatted for FDNY compliance, insurers, and project records.
Emergency Response
If an emergency occurs, the guard alerts workers, activates the fire alarm, contacts the FDNY, and remains on scene to assist responders with access and hazard information.
35 feet, both eyes, until it’s cold
Clear the radius, watch the sparks, hold the post-op window. It’s a specific discipline — and Dahlcore staffs it with the right Certificate-of-Fitness personnel every time.

What Shapes Your Hot Work Watch
Dahlcore scopes every hot work watch to the operation and the site. These are the factors that shape the plan.
1. Type of Hot Work
Welding, torch-applied roofing, cutting, or grinding — each has different spark, heat, and post-op risk, and may require specific C.O.F. credentials.
2. Site Complexity
Occupied high-rises, concealed cavities, and combustible-adjacent zones raise monitoring and post-operation demands.
3. Number of Posts
Simultaneous hot work in multiple areas needs multiple watches, each with its own line of sight.
4. Coverage Duration
A short repair or a full construction phase, including the mandatory post-operation window — overnight, weekend, and holiday coverage available.
5. Documentation Needs
FDNY, insurer, and GC expectations for logs, sign-offs, and photos are built into the plan.
Hot Work Watch FAQ
Clear answers for New York contractors, GCs, and building owners. For anything not covered here, call 212-208-0900.
What is hot work watch, and when is it required in NYC?
Hot work watch is fire-safety monitoring required during any operation that produces heat, sparks, or open flame — welding, cutting, brazing, grinding, torch work, or soldering. Under the NYC Fire Code (Chapter 26) and NFPA 51B, a certified fire watch must be present during all hot work and for a minimum of 30 to 60 minutes afterward.
What FDNY certifications do hot work watch guards need?
A NYC hot work watch must be performed by a guard holding the appropriate FDNY Certificate of Fitness — for hot work this is the fire guard for hot work (F-02) and, for torch-applied operations such as roofing, the torch-operations credential (G-60). Dahlcore matches guards to each assignment based on the certificate the work requires.
How is hot work watch different from general fire watch?
General fire watch is required when a building’s alarm, sprinkler, or suppression system is impaired or out of service. Hot work watch is required specifically during active heat- or spark-producing operations, regardless of whether suppression systems work. Both can be required on the same site at once.
How quickly can Dahlcore deploy a hot work watch guard?
Dahlcore operates 24/7 with same-day dispatch available for most New York locations, subject to availability. Call 212-208-0900 with your site address, the type of hot work, coverage hours, and number of posts to confirm timing.
What documentation does Dahlcore provide?
Each assignment includes a completed patrol log, a post-operation surveillance sign-off, and an incident report if a hazard is identified — supporting FDNY compliance, insurance, and project liability protection. Certificates of insurance are available on request.
What determines the scope of a hot work watch assignment?
The type of hot work, site complexity, number of posts, coverage duration, and documentation requirements. Dahlcore provides a written coverage recommendation after a quick assessment — call 212-208-0900 or email Ian.Dahlberg@Dahlcore.com.
Does Dahlcore cover both scheduled and emergency hot work?
Yes. Alongside planned construction and renovation coverage, Dahlcore provides same-day and after-hours hot work watch for emergency and urgent repair work, subject to availability.
How long is the post-operation watch?
NFPA 51B requires a minimum of 30 to 60 minutes of monitoring after hot work ends. Sites with concealed cavities or complex layouts may warrant a longer watch, which Dahlcore scopes into the plan.
