First known science-based boil-water advisory (1866) John Snow's 1849 recommendation that water be "filtered and boiled before it is used" is one of the first practical applications of the germ theory of disease in the area of public health and is the antecedent to the modern boil water advisory. Snow demonstrated a clear understanding of germ ...
The Reactor Protection System (RPS) is a system, computerized in later BWR models, that is designed to automatically, rapidly, and completely shut down and make safe the Nuclear Steam Supply System (NSSS – the reactor pressure vessel, pumps, and water/steam piping within the containment) if some event occurs that could result in the reactor entering an unsafe operating condition.
The anticipate, recognize, evaluate, control, and confirm (ARECC) decision-making framework began as recognize, evaluate, and control.In 1994 then-president of the American Industrial Hygiene Association (AIHA) Harry Ettinger added the anticipate step to formally convey the duty and opportunity of the worker protection community to proactively apply its growing body of knowledge and experience ...
These biological agents can cause adverse health effects in workers. Influenza is an example of a biological hazard which affects a broad population of workers. [14] Exposure to toxins generated by insects, spiders, snakes, scorpions, [15] [16] [17] etc., require physical contact be made between the worker and the living organism.
The essential service water system (ESWS) circulates the water that cools the plant's heat exchangers and other components before dissipating the heat into the environment. Because this includes cooling the systems that remove decay heat from both the primary system and the spent fuel rod cooling ponds, the ESWS is a safety-critical system. [ 7 ]
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.
The Health Hazard Evaluation (HHE) program is a workplace health program administered by the National Institute for Occupational Safety and Health (NIOSH) by which employees, employers, and labor unions can request assistance from the HHE program at no cost to them. [1]
The Hierarchy of Controls Applied to NIOSH Total Worker Health is a conceptual model for prioritizing efforts to advance the safety, health, and well-being of all workers. This model applies the framework of Total Worker Health approaches to the traditional Hierarchy of Controls used in occupational safety and health. Like the traditional ...
