Spraying cementitious or intumescent within 50 feet of:
Electrical panels, motors, or sensors
Fire alarm devices or sprinkler heads
Finished surfaces, windows, or equipment
Other trades working nearby
B. Containment Methods
Method
Application
Requirement
Poly-sheeting barriers
Vertical surfaces, equipment
Floor coverings
Protect walking surfaces
Zipper access doors
Entry through barriers
Negative air machines
Enclosed spray areas
C. Containment Inspection
Check
Frequency
Tears or gaps in poly-sheeting
Tape adhesion (edges, seams)
Negative pressure (door test)
HEPA filter status
Fireproofing Note: Overspray containment is not just quality control - it prevents electrical shorts, sprinkler failure, and slip hazards.
3. Mechanical Ventilation
A. When Required
Per 29 CFR 1926.57 and 1926.1153 Table 1, mechanical ventilation is required when:
Spraying in confined spaces (tanks, ducts, shafts, attics, crawl spaces)
Spraying in enclosed areas without natural airflow (interior rooms, basements)
Airborne dust or vapor levels exceed 50% of PEL (silica: 25 µg/m³)
Worker complains of odor, dizziness, or irritation
B. Ventilation System Requirements
Setting
Requirement
Confined space
Enclosed room
Open steel (outdoors)
High dust area
C. Monitoring
Parameter
Method
Action Level
Silica dust
Air sampling (personal)
Solvent vapors
PID meter or colorimetric tubes
Airflow
Anemometer
Fireproofing Note: Intumescent solvent vapors are heavier than air - collect in low spots (floor, pits). Exhaust at floor level.
4. Fire Watch (Hot Work Near Fireproofing)
A. When Required
Per 29 CFR 1926.352(e), a Fire Watch is required when hot work (welding, grinding, cutting) is performed within 35 feet of:
Intumescent primers or topcoats (flammable)
Fireproofing boards or dust
Solvent storage or open pails
Sparks or slag can travel to fireproofed surfaces
B. Fire Watch Person Requirements
Requirement
Detail
Dedicated person
Extinguisher
Communication
Duration
Training
C. Fire Watch Checklist
Check
Before
During
After (60 min)
Area clear of flammables
Fireproofing Note: Intumescent can smolder for 30-60 minutes before flaming. The fire watch must stay after work stops.
5. Wash Stations (Eyewash & Handwashing)
A. Eyewash Station Requirements
Per 29 CFR 1910.151(c), eyewash facilities shall be provided where corrosive materials (cementitious, pH 12-13) are used.
Requirement
Detail
Location
Unobstructed access
Water flow

Inspection
B. Handwashing Station Requirements
Per 29 CFR 1926.51, handwashing facilities shall be provided where irritants (silica, solvents, cementitious) are handled.
Requirement
Detail
Location
Components
Temperature
Waste container
C. When to Wash
Before eating, drinking, smoking
Before using restroom
After removing gloves or coveralls
Immediately after chemical contact with skin
Before leaving site
Fireproofing Note: Alkaline cementitious residue on hands can transfer to food, eyes, or restroom – wash before any break.
6. Monitoring & Recordkeeping
Control
Monitoring Frequency
Record Retention
Air sampling (silica)
Ventilation system inspection
Eyewash station
Fire watch log
7. Emergency Procedures
