Lack of clean water is able to complicate health. This could easily cause dehydration in children and adults. If someone is dehydrated, they won't be able to function properly and if they stay like this for long, this can cause a risk of death. Lack of clean water can easily turn into hygiene problems because the child wouldn't have a way to clean themselves or even do something as simple as washing their hands. This can transfer many bacteria only making the children catch illnesses. This, therefore, would prevent them from learning. This also goes for teachers because if the teachers do not have proper hygiene, they won't be able to teach. Once again this would affect children as well because children wouldn't have anyone to learn information. This would result in a bad education.
The answers are a smoke detector, a telephone, and a garbage can. The fire extinguisher is an optional thing to have, so you can be super careful. Unless you're talking about a restaurant's kitchen, then you have to have a fire extinguisher because it is a required thing to have.
Hope that helps.
