Hierarchy of hazard control is a system used in industry to prioritize possible interventions to minimize or eliminate exposure to hazards. [a] It is a widely accepted system promoted by numerous safety organizations.
Preventive healthcare strategies are described as taking place at the primal, [2] primary, [13] secondary, and tertiary prevention levels. Although advocated as preventive medicine in the early twentieth century by Sara Josephine Baker, [14] in the 1940s, Hugh R. Leavell and E. Gurney Clark coined the term primary prevention.
The purpose of the nurse is to retain this system's stability through the three levels of prevention: Primary prevention to protect the normal line and strengthen the flexible line of defense.

The triangle shows a relationship between the number of accidents resulting in serious injury, minor injuries or no injuries.

[1] Heinrich was a pioneer in the field of workplace health and safety.
All products and services have environmental impacts, from the extraction of raw materials for production to manufacture, distribution, use and disposal. Following the waste hierarchy will generally lead to the most resource-efficient and environmentally sound choice but in some cases refining decisions within the hierarchy or departing from it can lead to better environmental outcomes.
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 in a publication referred to as Biosafety in Microbiological and Biomedical Laboratories (BMBL).
