Mold Remediation >> Mold Remediation Protocol

If the remediation job disturbs mold and mold spores become airborne, then the risk of respiratory exposure goes up. Actions that are likely to stir up mold include: breakup of moldy porous materials such as wallboard; invasive procedures used to examine or remediate mold growth in a wall cavity; actively stripping or peeling wallpaper to remove it; Mold Remediation Protocol and using fans to dry items.

The primary function of Personal Protective Equipment (PPE) is to avoid inhaling mold and mold spores and to avoid mold contact with the skin or eyes. The following sections discuss the different types of PPE that can be used during remediation activities. Please note that all individuals using certain PPE equipment, such as half-face or full-face respirators, must be trained, must have medical clearance, Mold Remediation Protocol and must be fit-tested by a trained professional. 

In addition, Mold Remediation Protocol the use of respirators must follow a complete respiratory protection program as specified by the Occupational Safety and Health Administration (see Resources List for more information).Skin and Eye Protection Personal Protective Equipment remediation worker with limited PPE.

Long gloves that extend to the middle of the forearm are recommended. 

The glove material should be selected based on the type of materials being handled. If you are using a biocide (such as chlorine bleach) or Mold Remediation Protocol a strong cleaning solution, you should select gloves made from natural rubber, neoprene, nitrile, polyurethane, or PVC. If you are using a mild detergent or plain water, ordinary household rubber gloves may be used. 

To protect your eyes, use properly fitted goggles or a full-face respirator with HEPA filter. Goggles must be designed to prevent the entry of dust Mold Remediation Protocol and small particles. Safety glasses or goggles with open vent holes are not acceptable.Respiratory Protection Respirators protect cleanup workers from inhaling airborne mold, mold spores, and dust. 

Minimum: When cleaning up a small area affected by mold, you should use an N-95 respirator. This device covers the nose and mouth, will filter out 95% of the particulates in the air, and is available in most hardware stores. In situations where a full-face respirator is in use, Mold Remediation Protocol additional eye protection is not required. 

Limited: Limited PPE includes use of a half-face Mold Remediation Protocol or full-face air purifying respirator (APR) equipped with a HEPA filter cartridge. These respirators contain both inhalation and exhalation valves that filter the air and ensure that it is free of mold particles. Note that half-face APRs do not provide eye protection. 

In addition, the HEPA filters do not remove vapors or gases. You should always use respirators approved by the National Institute for Occupational Safety and Health (see Resources List). Full: In situations in which high levels of airborne dust Mold Remediation Protocol or mold spores are likely or when intense or long-term exposures are expected (e.g., the cleanup of large areas of contamination), a full-face, powered air purifying respirator (PAPR) is recommended. 

Full-face PAPRs use a blower to force air through a HEPA filter. The HEPA-filtered air is supplied to a mask that covers the entire Mold Remediation Protocol face or a hood that covers the entire head. The positive pressure within the hood prevents unfiltered air from entering through penetrations or gaps. Individuals must be trained to use their respirators before they begin remediation. 

The use of these respirators must be in compliance with OSHA regulations (see Resources List).Disposable Protective Clothing Disposable clothing is recommended during a medium or large remediation project to prevent the transfer and spread of mold to clothing Mold Remediation Protocol and to eliminate skin contact with mold. Limited: Disposable paper overalls can be used. 

Full: Mold-impervious disposable head and foot coverings, and a body suit made of a breathable material, Mold Remediation Protocol such as TYVEK‚®, should be used. All gaps, such as those around ankles and wrists, should be sealed (many remediators use duct tape to seal clothing). Containment Tips Always maintain the containment area under negative pressure. 

Exhaust fans to outdoors and ensure that adequate makeup air is provided. If the containment is working, the polyethylene sheeting should billow inwards on all surfaces. If it flutters or billows outward, Mold Remediation Protocol containment has been lost, and you should find and correct the problem before continuing your remediation activities.

The purpose of containment during remediation activities is to limit release of mold into the air and surroundings, Mold Remediation Protocol in order to minimize the exposure of remediators and building occupants to mold. Mold and moldy debris should not be allowed to spread to areas in the building beyond the contaminated site.

The two types of containment recommended inTable 2are limited and full. The larger the area of moldy material, the greater the possibility of human exposure and the greater the need for containment. In general, the size of the area helps determine the level of containment. However, Mold Remediation Protocol a heavy growth of mold in a relatively small area could release more spores than a lighter growth of mold in a relatively large area. 

Choice of containment should be based on professional judgment.10The primary object of containment should be to prevent occupant and remediator exposure to mold. Limited containment is generally recommended for areas involving between 10 and 100 square feet (ft2) of mold contamination. The enclosure around the moldy area should consist of a single layer of 6-mil, Mold Remediation Protocol fire-retardant polyethylene sheeting. 

The containment should have a slit entry and covering flap on the outside of the containment area. For small areas, the polyethylene sheeting can be affixed to floors and ceilings with duct tape. For larger areas, Mold Remediation Protocol a steel or wooden stud frame can be erected and polyethylene sheeting attached to it. 

All supply and air vents, doors, chases, Mold Remediation Protocol and risers within the containment area must be sealed with polyethylene sheeting to minimize the migration of contaminants to other parts of the building. Heavy mold growth on ceiling tiles may impact HVAC systems if the space above the ceiling is used as a return air plenum. In this case, containment should be installed from the floor to the ceiling deck, and the filters in the air handling units serving the affected area may have to be replaced once remediation is finished.
