While proper procedures and training can minimize the chances of an accidental fire, laboratory workers should still be prepared to deal with a fire emergency should it occur. In dealing with a laboratory fire, all containers of infectious materials should be placed into autoclaves, incubators, refrigerators, or freezers for containment.
Laboratory glassware is composed of silica, which is considered insoluble in most substances, with a few exceptions such as hydrofluoric acid or strong alkali hydroxides. Though insoluble, a minute quantity of silica will dissolve in neutral water, which may affect high precision, low threshold measurements of silica in water.
The distance from the mean is measured in standard deviations. It is named after Stanley Levey and E. R. Jennings, pathologists who suggested in 1950 that Shewhart's individuals control chart could be used in the clinical laboratory. [5] The date and time, or more often the number of the control run, is plotted on the x-axis.
In natural and social science research, a protocol is most commonly a predefined procedural method in the design and implementation of an experiment.Protocols are written whenever it is desirable to standardize a laboratory method to ensure successful replication of results by others in the same laboratory or by other laboratories.
The FDA requires nonclinical laboratory studies on new drugs, food additives, and chemicals to assess their safety and potential effectiveness in humans in compliance with 21 CFR Part 58, Good Laboratory Practice for Nonclinical Studies under the Federal Food Drug and Cosmetic Act and Public Health Service Act.

In a 2013 article for Slate, Mark Vanhoenacker explains that using your knife with the hand that you favor to cut and then placing it down so that you can switch your fork to your dominant hand is ...
An ordinary glovebox, showing the two gloves for manipulation, with airlock on the right. The most straightforward type of air-free technique is the use of a glovebox.A "glove bag" uses the same idea, but is usually a poorer substitute because it is more difficult to purge, and less well sealed.
Eliminating hazards and substituting safer alternatives can be challenging to implement within existing processes. These strategies are most effective when applied during the design or development phases of a workplace, tool, or procedure. At this stage, they often represent the most straightforward and cost-effective solutions.
