Mold
Molds are fungi which is a classification of organisms separate from plants and animals. There are thousands of known species. Some highly dangerous, some are not. Some molds, known as toxic molds, produce mycotoxins which are substances toxic to animal and human life. Molds reproduce by means of spores which may remain airborne for days or weeks. When spores land on a surface suitable to sustain life, they begin to grow.

Organic Material

This is the matter that has come from once living organisms. Organic matter serves as nourishment for molds and is capable of decay. Examples of Organic Matter are:
wood;

• cardboard
• the paper covering drywall;
• the paper covering most ceiling and wall building insulation; and
• furniture and clothing made of fabrics containing cotton, wool and / or leather.

Personal Protective Equipment
