Correct answer: C. 10 minutes

TDLR rules specify that multi-use implements, after being thoroughly cleaned, must be fully immersed in an EPA-registered disinfectant solution for at least 10 minutes, or the time recommended by the manufacturer if it's longer. This ensures proper sterilization.

  • B. 15 minutes is longer than the minimum required, but 10 minutes is the TDLR standard.
  • D. 20 minutes is longer than the minimum required, but 10 minutes is the TDLR standard.
