Gloves should be worn when cleaning blood due to the high risk of infection transmission, and it's wise to wear gloves when handling broken glass to prevent cuts, although not explicitly required. Caution is advised when wearing gloves around rotating equipment due to the risk of entanglement.
You should wear gloves in cases where there is a risk of exposure to hazardous materials or situations that could compromise safety. Specifically, gloves should be worn when cleaning blood on a surface as there is a high risk of infection transmission, including Hepatitis B (HBV). Blood can remain infective on surfaces for up to seven days; therefore, using gloves helps prevent direct contact and reduce the risk of infection.
Additionally, while cleaning broken glass is not explicitly mentioned as a situation requiring gloves, it is generally prudent to wear gloves to protect from cuts and potential infection. When working around rotating equipment, gloves might not be recommended as they can pose a danger of entanglement; thus, other safety measures should be taken.
