Safety Aspects
Here the safety aspects of the exercises should be written. Because of the different rules in different countries this will probably never be correct for every user. It should at least contain HMDS for the chemical compounds used or relevant links to used equipment.

Equipment
Description of the equipment needed and used during the exercises.

Preparation for the lab Supervisor
The preparation that the lab Supervisor needs to do to ready the lab.

Feedback from Users and Supervisors
Here there should be a link to a open page where people who have used the exercise can leave feedback. How the exercises worked and troubles in performing it.
