Fumigation is a hazardous operation. Generally it is a legal requirement that the operator who carries out the fumigation operation holds official certification to perform the fumigation, as the chemicals used are toxic to most forms of life, including humans. [1] Post operation ventilation of the area is a critical safety aspect of fumigation.
Air flow in fume hood demonstrated by dry ice fog. A fume hood is typically a large piece of equipment enclosing six sides of a work area (including a movable sash window or door), the bottom of which is most commonly located at a standing work height (at least 28 to 34 inches (71 to 86 cm) above the floor).
Chemicals are also used for sterilization. Heating provides a reliable way to rid objects of all transmissible agents, but it is not always appropriate if it will damage heat-sensitive materials such as biological materials, fiber optics, electronics, and many plastics. In these situations, chemicals either in a gaseous or liquid form, can be ...
used as a portable autoclave Biological and chemical indicators: Used to ascertain if a certain process has been completed, e.g. spores used in an autoclave are killed if autoclaving is properly done Filters: •Candle filter: used as household water filters and as filters for large particles in the laboratories
A drench hose is an equipment that can spray water to a specific spot of the chemical exposure on individual's body. The benefit of a drench hose is that it can be applied to an individual who cannot reach a normal eyewash or shower station or in the case where the eyewash and shower station are unavailable.
Sizing of HEPA filters and an internal damper are used to balance these air volumes. This type is not safe for work with hazardous chemicals even when exhausted with a "thimble" or canopy to avoid disturbing internal air flow. [3]: 8–9 The Type A2 cabinet, formerly designated A/B3, has a minimum inflow velocity of 100 ft/min.
The solution is used in many areas, including hospitals, laboratories, nursing homes, funeral homes, dental and veterinary facilities, and anywhere else where control of pathogens is required. [ 2 ] 1% Virkon has a wide spectrum of activity against viruses , some fungi , and bacteria . [ 3 ]
In laboratory use, the most common desiccators are circular and made of heavy glass. There is usually a removable platform on which the items to be stored are placed. The desiccant, usually an otherwise-inert solid such as silica gel, fills the space under the platform. Colour changing silica may be used to indicate when it should be refreshed.
