The course is focused on understanding the basics of safety at work (not only) in the chemical industry. That inappropriate change process at work can lead to an accident with serious consequences. They should know that some values ​​do not need to be calculated exactly. Even approximate result is often sufficient, showing whether or not ther is any sanger. This course does not turn the students in experts, but it provides them with basic knowledge and makes them aware that any change to production mana gement needs to be considered carefully, taking into account all aspects.

Students will be able to:

Calculate if and what is risk during accident in a chemical factory.

Proper procedures and how (before the crash) estimate (approximately calculate) the consequences (which residents will be evacuated).

Evaluate the risks of storing and processing of flammable substances.

Calculate what must be ventilation rate when working with toxic substances and will know what to do with the outgoing gas.
