• B. Lethal displacement
• C. Lethal dose
• D. Lethal determination

Answer: (C)

In safety terminology, LD stands for "Lethal Dose." This term is used to describe the amount of a substance required to cause death in a specified proportion of a test population, typically expressed as a statistical measure such as LD50, which indicates the dose at which 50% of the test subjects are expected to die. Understanding LD is crucial for assessing the toxicity of substances and establishing safety protocols when working with hazardous materials in any environment. Determining the Lethal Dose helps in evaluating risks and ensuring proper handling and safety measures are in place to protect individuals from potential harm. This understanding is vital for professionals in various fields, particularly in safety, health, and environmental sectors, to mitigate risks associated with toxic exposure.
