Sometimes people make mistakes without even realizing it. These are called "latent human errors." Imagine you're playing with your toys, and you accidentally knock over a glass of juice. You didn't mean to do it, but it happened anyway. Similarly, sometimes adults make mistakes that they don't even realize are mistakes until it's too late, and something bad happens. These mistakes might happen because of something like being tired or distracted, or because they didn't receive enough training. Even though the mistake wasn't intentional or obvious, it can still cause problems, just like how the spilled juice caused a mess on the floor. To prevent latent human errors, it's important for adults to be aware of the possibility of making mistakes, and to take steps to minimize the chance of something going wrong.
