Vented balance safety enclosures are used in pharmaceutical, chemical, biological, and toxicological laboratories to provide maximum containment for weighing operations in weighing scales. In laboratories weighing is generally regarded as a highly hazardous operation because it involves direct handling of pure substances. Fume hoods, also known as laboratory chemical hoods, are one of the most important and widely used engineering controls to protect workers in laboratories. Fume hoods were introduced about 100 years ago to safeguard personnel working with hazardous materials. While many changes and improvements have been made, the basic concept and design of fume hoods remains the same. Air is drawn from the workplace, around the worker and into the front of the hood, and is then exhausted out of the laboratory. Most laboratory hoods are described as constant air volume (CAV) hoods because they draw a constant amount of air at all times.
