When working with solvents, which of the following is essential for safety?

When working with solvents, personal protective equipment (PPE) is essential for safety because it provides a critical layer of protection against exposure to harmful chemicals. Solvents can release vapors that are hazardous to health, and direct skin contact can lead to irritation or more serious health issues. PPE such as gloves, goggles, respirators, and protective clothing helps to minimize these risks by creating a barrier between the worker and the solvent.

While other factors like proper lighting, noise reduction, and physical barriers can contribute to a safer working environment, they do not directly address the specific respiratory and dermal hazards that solvents present. PPE specifically targets the hazards associated with chemical exposure, making it a fundamental component of safety when handling solvents.
