Definition

Noun: 1. The margin required in order to insure safety: The amount by which a system's actual or available capacity exceeds the minimum required for safe operation. It is a buffer or allowance for error, uncertainty, or unforeseen stress. * In engineering, the margin of safety is the strength of the material minus the anticipated stress.

Usage

The term "margin of safety" is used to describe a calculated or inherent buffer that prevents failure. It is a critical concept in fields like engineering, finance, and project management, where it quantifies the degree of safety or risk.

Examples

• Noun:
  • The bridge was designed with a large margin of safety to withstand earthquakes.
  • When investing, a wise strategy is to buy stocks at a price below their intrinsic value, creating a margin of safety against market downturns.

  • Always build in a margin of safety when estimating project timelines.
• "A narrow/wide/slim margin of safety": Describing the size of the buffer.
  • The system is operating with a slim margin of safety, so any additional load is dangerous.
