Guidelines in Case of an Laboratory Emergency

JoVE 10379

Robert M. Rioux & Zhifeng Chen, Pennsylvania State University, University Park, PA

The most common laboratory emergencies include chemical spills, fire or explosion, electric shock, and personnel injuries. Most laboratory accidents occur due to poor planning or lack of attention. Therefore, it's always better to prevent accidents (being proactive) than having to take any actions during an emergency (being reactive). For example, always wear proper personal protective equipment (PPE) in the laboratory. Regular laboratory inspection and equipment maintenance is beneficial to prevent laboratory accidents. However, once the emergency occurs, it's also essential to know what to do. Ensure your personal safety first and then call local emergency responders, when and if necessary. The extent of your response will depend on the seriousness of the incident and documented laboratory protocols for dealing with such incidents. Stay calm and take proper actions according to the type and level of emergency.

Fume Hoods and Laminar Flow Cabinets

JoVE 10372

Robert M. Rioux & William A. Elliott, Pennsylvania State University, University Park, PA

Fume hoods and laminar flow cabinets are engineering controls that operate under similar principles. Both use a constant flow of air to prevent contamination of the laboratory environment and its inhabitants. Fume hoods prevent hazardous substances from exiting the hood workspace, whereas laminar flow cabinets prevent contaminants from entering the cabinet workspace. Fume hoods are ventilation systems designed to minimize exposure to hazardous vapors, fumes, and particles. A constant flow of air is drawn into the hood opening, limiting the escape of vapors, fumes, and particles, and then is pulled out through the exhaust. Laminar flow cabinets are used to maintain a sterile/clean environment by constantly flowing high-efficiency particulate arrestance (HEPA)-filtered air outwards, minimizing contaminated air entering the cabinet workspace. The HEPA-filtered air reduces the opportunity for harmful chemicals or particles from entering the laboratory. A HEPA filter removes 99.97% or greater of 0.3 µm particles.

Common Lab Glassware and Uses

JoVE 10161

Source: Laboratory of Dr. Neal Abrams — SUNY College of Environmental Science and Forestry

Glassware is a regular appearance in the professional chemistry laboratory, because it has a relatively low cost, extreme durability, and specific levels of precision. While some labware is being supplemented with plastic or even everyday kitchen materials, glass is still the standard material by which laboratory work is done. While there are few rules about glassware, there are some best practices for use that set the groundwork for good techniques in the lab. Glass is ubiquitous in the chemistry laboratory, but not all glass is the same. Standard consumer-grade glass is known as "soda-lime" or "float" glass. It is good for many applications, but cracks under rapid heating and cooling applications due to expansion/contraction. Borosilicate glass is used to solve this problem in the lab. Made with an introduction of small amounts of boron, borosilicate glass has a very low coefficient of expansion, which prevents internal stresses. The most common trade name for borosilicate glass is Pyrex, the same type of glass used in some kitchen bakeware. While borosilicate glass is thermally robust, the impurities found in borosilicate and standard glass lead to a li
