Introduction
Laboratory equipment can be hazardous if they are not used and maintained properly. Laboratory personnel must be trained on the proper use of laboratory equipment prior to using the equipment. Glassware is designed for a specific purpose. It should only be used for that purpose. "Makeshift" apparatus may be unstable and could lead to accidents and injuries. When selecting glassware, determine the compatibility of the glassware with the chemicals or process. Some chemicals react with glass or cause damage (etch) glass. If your process involves temperature or pressure changes, ensure the glassware can withstand the changes. Many dangers lurk in the laboratory. The most obvious risks are chemical hazards, but unsafe usage of laboratory apparatus can lead to disastrous consequences as well. There are certain procedures which must be observed when handling laboratory apparatus to reduce accidents and prevent injury. Working safely with hazardous chemicals requires proper use of laboratory equipment. Maintenance and regular inspection of laboratory equipment are essential parts of this activity. Many of the accidents that occur in the laboratory can be attributed to improper use or maintenance of laboratory equipment. This chapter discusses prudent practices for handling equipment used frequently in laboratories.
The most common equipment-related hazards in laboratories come from devices powered by electricity devices for work with compressed gases, and devices for high or low pressures and
