BACK PRESSURE

Pressure against the flow of liquids or air due to various imposed constrictions; e.g., air pressure working against a fan (air mover) within an air stream that is being compressed, as under a carpet or in an interstitial cavity during drying.


BACKCOAT

Adhesive applied to the back side of woven goods. The back coat serves to add strength and stability to the weave, while increasing its stiffness (_hand,_ or feel).


BACKFILL

Soil or other material (e.g. hardcore) which is replaced in an area that was previously excavated.


BACTERIA

Extremely small (generally from 0.4-10 microns in diameter), single-cell microscopic organisms. They are the most numerous organisms on earth and are formed everywhere, especially in soil. Because they are microscopic, they easily become airborne.


BACTERICIDE

A substance that kills specific bacteria, both pathogenic and non-pathogenic, though not necessarily all their spores (e.g., chlorine bleach, quaternary ammonium chloride), when used according to label directions.


BACTERIOSTAT

A substance, usually chemical, that prevents the growth of specific bacteria but does not necessarily kill them or their spores when used according to label directions.

BAILEE INSURANCE

Insurance purchased to cover the bailey?s legal liability for loss to property belonging to others, while in the bailey?s care and custody.


BALANCED DRYING

The equalization of evaporation and dehumidification. An ideal drying situation in which the rate of evaporation of moisture from structure and contents is equal to or slightly less than the rate of dehumidification or moisture removal from the material being dried.
