Set Up a Safe Welding Work Area

A. Finished-Project Specification

Outcome: one welding booth or temporary hot-work area with a marked hot-work boundary, protected surrounding surfaces, confirmed ventilation, staged equipment zones, fire-prevention controls, and a completed and signed welding-area readiness checklist. No cutting, grinding, or welding is performed as part of this chapter's finished work.

B. Readiness Zone Schedule (Component Schedule)

Zone	Quantity	Required Items	Setup Condition
Hot-work zone	1	Marked perimeter, barrier tape or stands, hot-work signage	Boundary measured and marked before any equipment staging
Welding screens	As required to enclose worker sightlines toward other occupied areas	Fire-resistant welding screens or curtains	Stable, non-combustible, positioned without blocking ventilation or exits
Combustible protection	As required by the area assessment	Fire-resistant blankets, curtains, or shields	Placed over immovable combustible surfaces within the boundary
Fire-extinguishing equipment	1 extinguisher minimum	Fire extinguisher rated for the area's hazards; fire blanket where approved	Staged within accessible reach of the hot-work zone
Hot-metal cooling zone	1	Marked floor area, sacrificial covering where required	Separated from combustible material and foot traffic
Clean-metal and scrap zones	1 each	Designated floor or table area for each material category	Kept separate from the hot-metal cooling zone and each other
PPE and tool staging	1	Helmet, safety glasses, gloves, clothing, hearing protection, clamps, pliers, chipping tools, wire brushes, grinders, measuring tools	Staged within reach of the hot-work zone before authorization
Emergency access	1	Alarm access, marked exit, first aid, eyewash where required	Verified unobstructed by screens, barriers, or staged equipment

C. Material Takeoff

• Barrier and signage materials: barrier tape, cones or stands, and hot-work signage sufficient to mark the full perimeter of the intended hot-work boundary.
• Fire-resistant protection: fire-resistant blankets or curtains sufficient to cover every immovable combustible surface identified within the boundary.
• Floor protection: sacrificial floor covering sufficient for the marked hot-metal cooling location, where the floor surface requires it.
• Consumables: none beyond housekeeping and protective materials; this chapter does not consume welding consumables.
• Fastener and hardware schedule: not applicable. This chapter produces a documented work area, not a fastened assembly.

D. Acceptance Standards

Check	Standard
Hot-work boundary	Marked and measured before equipment staging; provides adequate clearance from all identified combustible material
Combustible protection	Every immovable combustible surface within the boundary is removed, relocated, or covered with approved fire-resistant material
Concealed-space check	Floor cracks, drains, wall openings, penetrations, pits, ducts, and adjoining rooms within spark-travel range are inspected and protected or isolated by an approved method
Screens and barriers	Positioned to block arc radiation from reaching other workers without blocking required ventilation or emergency access; stable and non-ignitable
Ventilation	Confirmed appropriate to the intended process and material; local exhaust, where used, positioned to capture fumes without disturbing intended shielding
Fire-extinguishing equipment	Extinguisher rated for the area's hazards is staged within accessible reach; fire blanket or spark-containment staged where approved
PPE and tool staging	All required PPE, clamps, and hand tools are staged within reach of the hot-work zone
Emergency access	Alarm access, exit, first aid, and eyewash where required remain unobstructed
Authorization	Readiness checklist completed and signed by the responsible person before any hot work is authorized

E. Preparation — Authorization and Task Review

1. Obtain shop authorization or the required hot-work permit. Confirm the permit or authorization applies to the intended location, date, and duration before proceeding.
2. Review the planned welding, cutting, grinding, material, process, duration, and location. Confirm the plan matches the chapter or task that will use this area.
3. Identify the responsible welder, supervisor, fire watch, and emergency contact. Record each name and role on the readiness checklist.

F. Area Assessment and Fire Protection

1. Inspect the area above, below, behind, beside, and on the opposite side of the intended work. Walk the full perimeter before staging any equipment.
2. Identify combustible walls, floors, ceilings, insulation, dust, liquids, gases, paper, wood, fabrics, vehicles, and stored materials. Record each item found within the intended boundary.
3. Remove combustible material beyond the required hot-work boundary where practical. Relocate movable combustibles to a distance confirmed by the responsible person's guidance.
4. Protect immovable combustibles with approved fire-resistant blankets, curtains, shields, or guards. Confirm coverage extends beyond the expected spark and heat path.
5. Inspect floor cracks, drains, wall openings, penetrations, pits, ducts, and concealed spaces for spark travel. Identify every opening within range of the intended work.
6. Cover or isolate openings only through an approved method that does not block required ventilation or drainage. Confirm the covering method itself is non-combustible and stable.

G. Boundary, Screens, and Ventilation

1. Establish the restricted hot-work perimeter with signs, barriers, and welding screens. Measure and mark the boundary before positioning equipment inside it.
2. Position screens to protect others from arc radiation while preserving ventilation and emergency access. Confirm sightlines toward occupied areas are blocked.
3. Confirm that screens cannot ignite, tip, or contact the arc or hot workpiece. Check screen stability and material rating before continuing.
4. Identify the ventilation method for the specific process and material. Confirm the method matches the process planned for this area.
5. Position local exhaust to capture fumes without pulling shielding gas away from the weld. Confirm exhaust placement relative to the intended work position.
6. Confirm make-up air and exhaust do not expose neighboring workers or occupied spaces. Trace the exhaust path to its final discharge point.
7. Identify whether respiratory protection or specialty ventilation is required. Record the determination and any required follow-up on the checklist.

H. Work Surface, Zones, and Equipment Staging

1. Inspect the work table, stands, clamps, fixtures, and floor for stability and grounding suitability. Confirm each item is stable and free of damage before use.
2. Remove oil, grease, solvent, dust, and combustible residue from the work surface. Clean the full surface, not only the immediate work location.
3. Establish separate zones for clean metal, consumables, hot metal, scrap, gas cylinders, tools, and completed coupons. Mark each zone clearly on the floor or table.
4. Secure compressed-gas cylinders upright and away from sparks, heat, traffic, and electrical circuits. Confirm cylinders intended for later use are staged, not connected, at this stage.
5. Protect hoses, leads, cords, and foot controls from sharp edges, hot metal, vehicles, and trip paths. Route staged cabling away from walkways.
6. Verify the welding machine disconnect, input power, cable routing, and dry location. Confirm the machine remains de-energized until Chapter 3's equipment inspection is complete.
7. Stage the required welding helmet, safety glasses, face shield, gloves, clothing, hearing protection, and respiratory equipment. Position PPE within reach of the hot-work zone.
8. Stage approved clamps, pliers, chipping tools, wire brushes, grinders, and measuring tools. Place each item in its designated tool zone.

I. Fire-Watch, Emergency Controls, and Final Authorization

1. Place an appropriate fire extinguisher within accessible reach. Confirm the extinguisher rating matches the hazards identified during the area assessment.
2. Stage fire blankets, spark containment, water or other firefighting media only when approved for the hazard. Do not stage a firefighting method not approved for the specific hazard present.
3. Verify alarm access, emergency exit, first aid, eyewash where required, and communication. Confirm each remains unobstructed by screens, barriers, or staged equipment.
4. Establish the fire-watch position and post-work monitoring duration. Record the assigned fire watch and the required monitoring period on the checklist.
5. Mark the hot-metal cooling location. Confirm the location is separated from combustible material and foot traffic.
6. Establish the method for identifying hot material to others. Record the method — tags, signage, or verbal notice — on the checklist.
7. Inspect lighting so work, leads, clamps, cylinders, and exits remain visible. Correct any area with inadequate lighting before continuing.
8. Confirm that flammable gas, oxygen enrichment, confined-space, or explosive dust conditions are not present. Stop and contact the responsible person if any condition cannot be ruled out.
9. Complete a documented walk-through using the welding-area readiness checklist. Verify every item in Section D against the physical area.
10. Correct every failed fire, ventilation, access, electrical, cylinder, PPE, screen, support, or housekeeping item. Re-inspect each corrected item before continuing.
11. Authorize arc initiation only after the responsible person signs the readiness record. Do not proceed to any later chapter's hot work without this signature.
