Laboratory Hoods Idexx Indonesia

Many materials used in laboratories can produce harmful vapors and vapors, and laboratory workers must take appropriate precautions to work safely with these ingredients. Often this means working inside a laboratory hood. This article describes several different ways in which laboratory hoods protect workers, and how workers must test that the hood is functioning properly.

Hoods can provide various types of protection for laboratory workers. First, the "sling" on the hood protects against physical hazards such as chemical sparks, fires and small explosions. To maximize this protection, the sling must be kept at the lowest practical level when working inside the hood.

Second, the bonnet prevents contaminants in the air from reaching the worker hood. Air flow must enter the hood, and therefore away from the worker, and contaminants must be captured before filtering and spent from the hood through the canal.

Although a lot of protection is provided by the hood, workers may still need to wear safety goggles, gloves and other equipment while working inside the hood.

Laboratory hoods will be useless if they are not functioning properly, and for this reason routine testing and maintenance must be carried out. Tests must be carried out when the hood is first installed, and periodically afterwards. Retesting must also be done every time there is a change in the laboratory ventilation system.

Testing a hood is a skilled procedure and workers must be trained in the measurements to be taken idexx indonesia and the equipment to be used. Usually the cross design (circulation around the hood) is examined first. Then the smoke tube is used inside the hood to ensure that the flow leads correctly to the outlet vent.

Finally the face speed is measured in several positions. This is the speed of air measured through the face (front) of the hood with an open sling. There are specifications for permissible airspeed (absolute and relative) on all surfaces, and for surface speeds relative to cross-design. Instruments that are properly calibrated like an anemometer must be used for this measurement.

If there are problems with some of these specifications, there are some minor adjustments (eg Baffle Interior hood) that can be made, but if the hood still fails, the problem must be reported to the supervisor.

In addition to understanding what the hood is doing, and how to test the hood, workers must be trained on how to use the hood correctly. The activity inside the hood must be regulated so that the air flow remains effective at all times. Experiments cannot be right on the edge
