Proper Protection Levels for Mold Removal

Proper Protection Levels for Mold Removal

Though Mold is an omnipresent material, many forms of it can be quite toxic and hazardous. Mold can cause a variety of help problems that produce symptoms ranging from the extremely mild to serious and sometimes even leading to death. When Mold assessment occurs, the contamination are given are rating, generally from I-III and sometimes a Level IV. The Mold remediation process determines which level of protection is required for the remediation/removal workers.

LEVEL I – Level I is designated for “small isolated areas”. This means Level I protection is required for areas of roughly 10 sq ft. This applies to things like ceiling tiles, or small floor or wall areas.

Specialized staff are not required, though they should be trained in proper cleaning and removal methods. This includes proper protection equipment. OHSA training standards required.

Dust suppression recommended.

Respiratory protection recommended (respirators or masks).

Unclean-able materials should be properly sealed and disposed of.

Immediate workspace is not to be occupied, adjacent areas OK except for small children.

Worker entrance/exit should be cleaned with detergent and damp mop.

Work Areas, entrance /exits should be free of visible dust or debris and dry upon completion.

LEVEL II – Level II is designated for “mid-sized isolated areas”. This covers a range of 10-30 sq ft (objects such as individual wallboard panels or ceiling panels).

Workspace and respiratory rules match that of Level II (No special staff required).

All surfaces under threat of contamination should be covered with secure plastic sheets.

Dust Suppression via misting of surfaces is again recommended.

Worker entrance/exit areas should be cleaned with HEPA vacuum and mild detergent.

Again, all areas should be free of visible dust or debris and be dry as well

LEVEL III – Level III covers “large isolated areas” the equivalent of 30-100 sq ft (areas of multiple floor or wall panels, etc).

Special staff requirements: Industrial hygienists or similarly trained environmental health and safety professionals with microbial investigatory experience (Mold remediation).

Again, securely cover all uncontaminated surfaces to prevent further spread.

All air ventilation systems in the work area and adjacent areas should be sealed with plastic.

Respirators, gloves and eye protection should be used per OHSA requirements.

Dust Suppression is required.

Items unable to be cleaned must be sealed and removed from site.

Cleanup along with exits/entrances as in previous Levels.

LEVEL IV – Level IV covers “extensive contamination”. This pertains to areas of 100 sq ft or greater; whole rooms to complete buildings.

Specialized Staff trained in hazardous material handling required.

Full face respirators with HEPA cartridges required.

Disposable protective clothing (head, shoes, hands, whole body) required.

Work area should be completely isolated, via plastic sheeting, duct tape, etc. This extends to all possible openings, ducts, grills, fixtures, etc.

Decontamination room with airlocks, combined with HEPA filter exhaust fan for negative pressurization required.

Removed materials must be sealed prior to removal and disposal.

Before isolation barriers are removed, full HEPA vacuuming and cleaning with detergent solutions are required.

After any Level of Mold remediation and removal is performed a re-evaluation and inspection should take place to determine the success of the operation. The above are requirements for professional removal of Mold. Know what to expect when you hire a company to inspect and remove Mold from any property. When you select a company be sure to research them thoroughly. Trust a local, qualified business with a proven record for Mold removal, remediation and assessment.
