What method can be classified as a substitution control measure?

• A. Using a less toxic chemical
• B. Implementing a new safety protocol
• C. Installing safety guards
• D. Providing protective gear

Answer: (A)

Substitution control measures involve replacing a hazardous element with something less dangerous to reduce risk and enhance safety. When selecting a less toxic chemical, the inherent risks associated with the original chemical are minimized, thereby providing a safer working environment. This reflects the goal of substitution control measures, which prioritize eliminating or reducing hazards by using safer alternatives. In contrast, the other choices focus on different strategies for managing risk. Implementing a new safety protocol involves changing procedures or regulations but does not replace the existing hazardous material. Installing safety guards focuses on preventing accidents by adding barriers but does not change the nature of the materials involved. Providing protective gear also seeks to reduce exposure to hazards through personal protection rather than altering the hazard itself. These approaches are important but do not fit the definition of substitution.
