Maintenance Requirements: The maintenance requirements depend on the type of portable fire extinguisher. Stored pressure or dry chemical type extinguishers do not require an internal examination. Water or steam type fire extinguishers should be discharged, disassembled and inspected annually (NFPA 10, 4-4.1.1).
Fiscus Name Meaning German: from Latin fiscus âbasketâ, a humanistic Latinization of the German name Korb. This is a metonymic occupational name for a basketmaker or a peddler, or a habitational name for someone who lived at a house distinguished by the sign of a basket.
A meniscus is the curved surface at the top of a column of liquid. In a science class, this liquid is usually water or some sort of aqueous solution, and the column is usually a graduated cylinder or a pipet. As you may have noticed, when water is in such a thin glass tube, it does not have a flat surface at the top.
