By Hazard


OEB - Occupational Exposure Band, a mechanism used to precisely assign chemicals into "categories" or "bands" based on their health outcomes and potency considerations. It also aligns chemicals in groupings based on OEL in order to establish safe handling guidelines.

Biological Safety Levels (BSL)

A biosafety level is a set of biocontainment precautions required to isolate dangerous biological agents in an enclosed laboratory facility. The levels of containment range from the lowest biosafety level 1 (BSL-1) to the highest at level 4 (BSL-4). In the United States, the Centers for Disease Control and Prevention (CDC) have specified these levels.

Animal Biological Safety Levels (ABSL)

Esco is the only company globally that offers the entire range of Biological Safety Cabinets including customized cabinets.


The use of radiation in the diagnosis and treatment of patients has considerably advanced the medical field, and have extended and saved numerous lives. Radiation usage, conversely, come with risks. Hence, it is necessary that those who are involved with radiation be sufficiently trained in radiation safety, radiation physics, the biologic effects of radiation, and injury prevention to ensure a person's safety.

Chemical Containment

An increasing number of industries are involved in working with or around chemicals and chemical products every day (i.e., pharmaceuticals, biological, food and the like). Chemical protection is fundamentally linked to other safety issues like personal protective equipment, engineering controls, workroom or laboratory procedures, electrical and fire safety, and hazardous waste disposal. Many chemicals have properties that make them hazardous. These substances can be physical and/or health hazards.

ATEX Rating

The ATEX Directive 99/92/EC classifies explosive atmospheres into area classes. This classification is applied to atmospheres where a combination of dusts, aerosols, vapors, gases, and air form an explosive mixture. Areas where this standard must be applied are, for example, oil refineries, paint shops, biogas power plants and peat processing plants.
