What type of PPE should you use to protect your hands when an unknown solution drips onto your hand?

Wearing gloves is essential for protecting your hands when handling unknown solutions, as they act as a barrier between your skin and potentially harmful substances. Different types of gloves are designed to withstand various chemicals and prevent direct contact, which is crucial in a laboratory setting where exposure to reactive or toxic materials can occur.

Using gloves ensures that if an unknown solution drips onto your hand, it will not make contact with your skin, thereby reducing the risk of burns, irritations, or systemic absorption of hazardous chemicals. Proper glove selection depends on the type of chemicals being used, as some materials offer better protection against specific substances than others.

In this scenario, the other options such as goggles, face shields, and closed-toe shoes provide important protection but do not directly safeguard your hands. Goggles protect your eyes, face shields provide additional protection for the face, and closed-toe shoes help shield your feet from spills or dropped equipment. However, none of these options offers the same level of hand protection that gloves do when dealing with unknown solutions.
