HSEα uses a pseudo-Cβ instead of the real Cβ atom for its calculation. The position of this pseudo-Cβ atom (pCβ) is derived from the positions of preceding Cα −1 and the following Cα +1. The Cα-pCβ vector is calculated by adding the Cα −1-Cα 0 and Cα +1-Cα 0 vectors. HSE is used in predicting discontinuous B-cell epitopes. [2]
Thermal work limit (TWL) is an index defined as the maximum sustainable metabolic rate that well-hydrated, acclimatized individuals can maintain in a specific thermal environment within a safe deep body core temperature (< 38.2 °C or 100.8 °F) and sweat rate (< 1.2 kg or 2.6 lb per hour). [1]
The European Union System for the Evaluation of Substances (EUSES) is a mathematical model for calculation of Predicted Environmental Concentrations (PEC) and human exposure. It may be used in Chemical Safety Assessments (CSA) and be cited in Chemical Safety Reports (CSR).
In engineering, a factor of safety (FoS) or safety factor (SF) expresses how much stronger a system is than it needs to be for an intended load.Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.

The Hierarchy of Occupational Exposure Limits, of which occupational exposure banding is a member. Occupational exposure banding, also known as hazard banding, is a process intended to quickly and accurately assign chemicals into specific categories (bands), each corresponding to a range of exposure concentrations designed to protect worker health.

In 1970, the US Occupational Health and Safety Act was signed into law, [6] which created the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health. Shortly after this law passed, OSHA implemented its first Permissible Exposure Limits, which were adopted directly from the 1968 ACGIH ...
