It is a calculation of the Minimum Breaking Strength (MBS) also known as Minimum Breaking Load (MBL) divided by a safety factor, usually ranging from 4 to 6 on lifting equipment. The factor can be as high as 10:1 or 10 to 1, if the equipment poses a risk to a person's life.
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.
In project management, level of effort (LOE) is a support-type project activity that must be done to support other work activities or the entire project effort. It usually consists of short amounts of work that must be repeated periodically.
A work-breakdown structure (WBS) [2] in project management and systems engineering is a deliverable-oriented breakdown of a project into smaller components. A work breakdown structure is a key project management element that organizes the team's work into manageable sections.
In project management, resource leveling is defined by A Guide to the Project Management Body of Knowledge (PMBOK Guide) as "A technique in which start and finish dates are adjusted based on resource limitation with the goal of balancing demand for resources with the available supply."
[7] [8] Gantt charts illustrate the start and finish dates of the terminal elements and summary elements of a project. [1] Terminal elements and summary elements constitute the work breakdown structure of the project. Modern Gantt charts also show the dependency (i.e., precedence network) relationships between activities. Gantt charts can be ...

The NIOSH lifting equation is a tool (now application) that can be used by health and safety professionals to assess employees who are exposed to manual lifting or handling of materials. [7] The NIOSH lifting equation is a mathematical calculation which calculates the Recommended Weight Limit (RWL) using a series of tables, variables, and ...
