15 Aug 7 Pivotal Tips for Mold Cleanup and Remediation To-Do’s
Molds can produce toxins and volatile organic compound (VOCs) as well as other metabolites. Molds grow in colonies and can be disseminated by wind and water as spores. Mold exposure can lead to allergic reactions, asthma, contact dermatitis, and other skin problems.
Outdoor environments are more likely to be contaminated by molds and other fungi than indoors.
They usually enter indoor environments through openings (windows or doors, cracks), and on surfaces of indoor objects (including people).
To grow and reproduce, they need moisture and organic substrate material. Certain situations, like severe flooding following a hurricane, can create ideal conditions for mold growth.
These conditions are present in affected areas. People who perform cleanup and remediation should be able recognize the presence or potential of mold and take steps to protect themselves.
Mold Cleaning: Definitions and Regulations
Mold cleanup depends on the extent of the problem. It can be done by anyone, including DIY cleanup, maintenance or remediation.
The Environmental Protection Agency (EPA) states that DIY cleanup is possible if the area affected is less than 10 feet. Maintaining moderately large areas of contamination (less then 30 square feet) is the goal.
Large-scale mold presence is likely to require remediation. To complete remediation work, a specialized contractor is recommended.
OSHA does not have any specific standards for indoor mold and fungus exposure. If the exposure is particularly dangerous, employers can still be fined by OSHA under the General Duty Clause.
The EPA has provided guidance for homeowners, schools and commercial property owners to help prevent and safely remove mold contamination.
Many states also have, or are creating, legislation that addresses fungal growth indoors.
Safety precautions for mold cleanup activities
Mold remediation workers should follow the following safety precautions:
- Protect the cleanup area and prevent anyone from getting in.
- Wear the appropriate personal protective equipment (PPE) and wear a mask if mold-contaminated material is present
- Avoid touching or inhaling mold spores with your naked skin or hands.
- Avoid allowing mold spores or other mold-causing substances to escape into the atmosphere where they could be inhaled. Be careful when looking behind wallpaper to prevent the release of spores.
- Take care to remove, bag, seal and dispose of any damaged materials such as drywall, carpeting and furniture.
- Avoid painting mold over; instead, use soap and water to clean surfaces.
- If you suspect or know that your HVAC system is contaminated by mold, don’t run it. Also, don’t use an HVAC system where dry materials could be disseminated. (For related reading, please see Why winterization is important for safety and health).
Protective apparel for mold cleanup and remediation tasks
The size of the mold problem will determine the type of protective clothing you need.
You can use a simple respirator, work gloves, safety glasses, or protective footwear for DYI cleanups of less than 10 feet.
For larger cleanups that cover less than 100 square feet, you will need more protection. Protective clothing and a half-face respirator are required for these projects.
Use a full-face respirator for severe contaminations of 100 square feet or more. Protect your body from head to toe with full-body protection.
Toxins at Home
Mold can not only pose a risk to remediation workers and cleaners, but also their families.
Take-home toxic substances are toxins such as mold spores that can stick to clothing, shoes, skin and tools of workers. They are then spread to the worker’s house, increasing the danger of the toxins.
There are several ways to deal with toxic substances in the home, including:
- Protective clothing that can be taken off
- Washing and shower facilities
- Policies of donning and donning
Mold can be a problem for employees who are exposed to it. Employers need to take the necessary precautions to protect employees and their families.
