Final answer:
Ethyl alcohol and isopropyl alcohol can be used for ETOH testing as disinfectants.
Step-by-step explanation:
The disinfectants that may be used for ETOH testing are ethyl alcohol and isopropyl alcohol. Ethyl alcohol, also known as ethanol, is the intoxicating ingredient found in alcoholic drinks and is commonly used as a disinfectant. Isopropyl alcohol, also called rubbing alcohol, has a similar molecular structure and is another commonly used disinfectant. Both these alcohols denature proteins and disrupt membranes, making them effective for disinfection.
