Outer wall of unicellular (bacterial/protista) organisms composed mainly of cellulose. Its purpose is to maintain the overall chemical makeup of the cell as well as for protection from the environment.

the document issued by DHS to an individual meeting the certification requirements as described in CCR Title 17, Sections 35083, 35085, 35087, 35089, or 35091.

Formal procedures for tracking samples and ensuring their integrity.

A sample preparation procedure for materials other than friable insulation in which, by means of acid digestion and ashing, it is possible to separate asbestos fibers from hard-to-analyze matrices. This preparation technique is used most often in conjunction with Electron Microscopy (EM) and is considered state-of-the-art for materials such as floor tile, plaster, and textured ceiling material.

A resistant, thick walled vegetative cell. More or less rounded.

A node formation characteristic of basidiomycetes that develops through cell division and elongation of a hypha. An outgrowth protrudes after nuclei division of the hyphal cell, resulting in the fusion (i.e. clamping) of the hyphal outgrowth to the original hypha creating a distinct “node”.

Club Shaped. Differs from obclavate by the orientation of spore formation. Club shaped spores develop with the “handle” end at the base.

An uncontaminated area or room which is a part of the worker Decontamination Enclosure System with provisions for storage of worker’s street clothes and clean protective equipment.

visual examination and, as applicable, collection of environmental samples upon completion of the Work of this section.

Typically a fruiting body of Ascomycetes usually an ascus formed inside. Must be broken to liberate spores. Compare to “perithecium.”

Round shaped

a structural element or fixture, including but not limited to, walls, floors, ceilings, doors, window molding, trim, trestles, tanks, stairs, railings, cabinets, gutters, or downspouts.

An asexual reproductive cell which, after liberation from the hyphal body, aids in reproduction and dissemination of a fungus.

Compacted group of hyphae, or synnema, bearing spores at the outer apices.

A controlled (though not always successful!) growth of an organism.

A device to allow ingress and egress from one room to another while permitting minimal air movement between the rooms, typically constructed by placing two overlapping sheets of plastic over an exiting or temporarily framed doorway, securing each along the top of the doorway, securing the vertical edge of one sheet along one vertical side of the doorway and securing the vertical edge of the other sheet along the opposite vertical side of the doorway. Other effective designs may be submitted for review.
