Equipment can be disinfected by being in contact with a chlorine solution for at least:

Disinfecting equipment with a chlorine solution is an important practice in sanitation and infection control. The minimum effective contact time for a chlorine solution to effectively disinfect surfaces and equipment is typically around 10 seconds. Chlorine solutions work by breaking down and denaturing proteins in pathogens, thereby neutralizing them. For many microorganisms, a contact time of 10 seconds is sufficient to achieve a high level of microbial reduction.

In public health recommendations, especially when considering the use of bleach as a disinfectant, maintaining the proper concentration and ensuring that surfaces remain wet for at least this duration is critical for effective disinfection. Research and guidelines from health organizations often cite 10 seconds as a standard, balancing efficiency and effectiveness in sanitization practices. Therefore, the answer effectively captures the standard required for the disinfection process using a chlorine solution.
