MSDS are important documentation that provides and explains valuable information about a chemical product. Information included in the MSDS is the name of the chemical, hazardous ingredients, targeted organs that should be protected, spill clean up methods, and what people should do in case of an emergency.
Maximum Contamination Level (MCL)
After flood damage restoration, water sources can be checked for MCL, which is the highest concentration of a particular constituent of drinking water that is permitted by federal and state Safe Drinking Water Act regulations.
Professionals engaging in plumbing, piping and HVAC work are referred to as mechanical contractors.
Membranes are thin and pliable roofing materials on flat roofs.

Microbes are microscopic microorganisms that include algae, viruses, bacteria, fungi, etc., and have the possibility of harboring or carrying a disease. There are disinfectants and cleaners that are designed to kill certain strains of microbes that harbor diseases.
Microbial Volatile Organic Compound (MVOC)
MVOC is produced during metabolic processes of microorganisms resulting in the distinctive musty, moldy and mildew odors.
Microorganisms are microscopic organisms that include bacteria, fungi and viruses. These microorganisms can carry pathogens that can cause diseases and these should be controlled through careful cleaning and maintenance.
Migration refers to the passage of water and moisture through walls due to absorption. The term can also be used to describe the passage of smoke and soot through pressure.
A coating or discoloration on moist surfaces due to molds or fungi is called mildew.

Molds are a form of fungi that are naturally occurring in nature. These microorganisms produce enzymes that digest dead organic matter and help in the natural process of decomposition. However, mold infestations that occur within the home and other establishments can cause serious health risks to its human inhabitants.
Molds are attracted to moisture, particularly on damp areas or surfaces, which have exposure to water damage. Molds propagate through spores released in the air and lands on moisture-rich surfaces.
Mop buckets are designed and used to submerge wet mops. These buckets contain a mop wringer to remove or to wring out contaminated or dirty water from mops. Mop buckets have built in casters to allow for easy movement around the floor.
Mop heads are the soft end of mops, usually made of cotton, rayon or synthetic materials, which are applied to floor surfaces for cleaning or finishing purposes. Wet mops are made of cotton to hold more dirty-mop solution for cleaning purposes. Finish mops are made of rayon or similar synthetic blends.
