  3. Biohazard disposal system

The correct answer is: One-handed recapping technique

Work practice controls refer to the practices and procedures put in place to reduce or eliminate exposure to hazardous materials in the workplace. Out of the given options, only the one-handed recapping technique is a work practice control. Option A, full-body protective gear, is considered to be personal protective equipment (PPE) rather than a work practice control. Option C, biohazard disposal system, refers to the proper disposal of hazardous materials and is not a work practice control. Option D, two-person operation method, is a work practice control for tasks that require more than one person, but it is not relevant to the use of hazardous materials. Therefore, option B is the correct answer.
