Which of the following is considered a safe work practice control?

Using proper gloves when handling chemicals is considered a safe work practice control because gloves serve as a barrier between the skin and potentially harmful substances, including bloodborne pathogens. This protective measure reduces the risk of exposure that healthcare workers and others in environments where exposure to blood or hazardous materials may occur face. Gloves must be selected based on the task's specific risks, including the type of chemical or biological material being handled, to provide effective protection.

In this context, the other options may not represent comprehensive safe work practice controls. Wearing face masks offers respiratory protection but does not prevent dermal exposure. Utilizing hand sanitizers is a good hygiene practice but should not replace the need for gloves when handling potentially infected materials. Removing gloves after tasks is necessary to prevent cross-contamination, but it is not a proactive measure to protect against exposure during the task itself, which is why the focus on wearing the correct gloves is what qualifies as a safe work practice control in this scenario.
