The possibility that a hazard will occur increases significantly when a critical limit is exceeded.
Of the 44 patients who died during the four-year study period, 40 had known CD4 levels below the critical limit within the six months prior to death, the researchers say.
Their extremely low densities mean that they are at the critical limit for self-reproduction.
The easiest way to appreciate the legal principles that unfold when there is an adverse outcome related to critical limits is to consider that you, the reader, could be called to task and required to explain during deposition or to a jury: a) each and every detail of your critical values policy and each entry on your critical limit list; b) the rationale and consensus process by which you selected them; and c) the manner in which they were originally derived, implemented, updated, changed, and practiced in your hospital setting or in point-of-contact areas.

HACCP involves seven principles: analyze hazards; identify critical control points; establish preventive measures with critical limits for each control point; establish procedures to monitor the critical control points; establish corrective actions to be taken when a critical limit has not been met; establish procedures to verify that the system is working properly; and establish effective recordkeeping.
We determined the critical limit and the detection limit of our assay as suggested by the IUPAC guidelines based on statistical calculations (18).
HAACP outlines preventive measures (such as minimum cooking temperatures) for each control point, requires procedures and instrumentation to monitor those control points, and prescribes corrective actions for when a critical limit is not met.
Although transfusion in most of our patients might have been indicated, values that trigger emergency transfusion and the low hemoglobin critical limit value need not be identical (10).
