Final answer:
After removing hair from a brush in a disinfection procedure, the next step is to rinse the brush with water and then soak it in a disinfectant solution according to manufacturer instructions to kill any remaining microorganisms.
Step-by-step explanation:
The correct step to take after removing all hair from a brush during a disinfection procedure is to soak the brush in disinfectant solution. Disinfection is an important process to eliminate microorganisms and prevent the spread of infection. After removing physical debris such as hair, the brush should be thoroughly rinsed with water to remove any remaining particles. Following that, the brush needs to be submerged in a proper disinfectant solution for the time specified by the manufacturer's instructions. This will ensure that any potential pathogens are effectively killed. It is important to follow safety guidelines and use personal protective equipment (PPE) when handling and applying disinfectants to prevent exposure to harmful chemicals.
