Remediation
Personal protective equipment (PPE)
In plain English
Disturbing mold — tearing out drywall, opening a wall cavity, stripping wallpaper, even running drying fans — puts spores in the air. Protective equipment keeps them out of your lungs, eyes and skin.
The minimum for any mold cleanup is an N-95 respirator, gloves that reach mid-forearm, and goggles without vent holes (ordinary safety glasses don't keep out fine dust). Bigger jobs step up to a half-face respirator with HEPA cartridges and disposable coveralls, and the largest to full-face respirators or powered air-purifying respirators (PAPRs) with full body coverage.
Anyone using a half-face or full-face respirator at work must be trained, medically cleared and fit-tested under an OSHA respiratory protection program, using NIOSH-approved respirators.
At a glance
| Level | What it includes |
|---|---|
| Minimum | Gloves, N-95 respirator, goggles |
| Limited | Gloves, N-95 or half-face respirator with HEPA filter, disposable overalls, goggles |
| Full | Gloves, disposable full-body clothing, head and foot coverings, full-face HEPA respirator (PAPR for long or heavy exposure) |
Key points
- N-95, long gloves, unvented goggles — the minimum.
- Half-face respirators give no eye protection; HEPA filters don't stop vapors.
- Nitrile, neoprene, natural rubber, polyurethane or PVC gloves with biocides or strong cleaners.
- In Texas, the N-95 is the recommended minimum and the assessor can require more.

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; 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, and must be fit-tested by a trained professional. In addition, the use of respirators must follow a complete respiratory protection program as specified by the Occupational Safety and Health Administration (OSHA) (see Resources List for more information).
Skin and Eye Protection
Gloves are required to protect the skin from contact with mold allergens (and in some cases mold toxins) and from potentially irritating cleaning solutions. 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 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 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.
Limited: Limited PPE includes use of a half-face 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 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 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 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, 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).
Sidebar: Always use gloves and eye protection when cleaning up mold!

CDC Mold Cleanup Guide — Before you enter any moldy site Best practice
- Protect yourself and loved ones against hazards. People with breathing problems like asthma or who have weakened immune systems should stay away from moldy sites. Children should not take part in disaster cleanup work. Check for loose power lines or gas leaks. Make sure the electricity and gas are turned off. Look for sagging ceilings or floors or other structural problems. Watch out for wet, muddy, or slippery floors.
- Protect your mouth and nose against breathing in mold: wear at least an N-95 respirator. If you plan to spend a lot of time removing moldy belongings or doing work like ripping out moldy drywall, wear a half-face or full-face respirator.
- Protect your skin. Wear protective gloves (non-latex, vinyl, nitrile, or rubber). Do not touch mold or moldy items with bare hands.
- Protect your eyes. Wear goggles that provide complete eye protection. Choose goggles designed to keep out dust and small particles. Safety glasses or goggles that have open vent holes will not protect you against dust and small particles.
After you leave a mold site:
- Shower and change your clothes. This will help you avoid carrying mold and other hazards back to your current living quarters.
