Safety and containment.

Airborne protection

HEPA filtration captures what the demo puts in the air before it reaches living space.

Physical barriers

Poly sheeting and zippered entries isolate the work zone from the rest of the unit.

Family safety

Unaffected rooms can often stay in use. HVAC to the work area is sealed so we are not circulating the problem.

Physical containment

Seal the work from living space so the job cannot walk down the hall.

• Poly barriers and zippered entries
• Floor protection so contaminants are not tracked
• HVAC registers sealed in the work zone

Air quality

Negative air and HEPA so the pressure points out, not into the house.

• Negative air machines when the file needs them
• HEPA scrubbers through the work
• Exhaust outside when the building allows it

Personal protection

The crew suits the category — not a t-shirt and a shop-vac.

• PPE matched to mold, sewage, or soot
• Decon before leaving the work area
• Training in handling contaminated materials
