Please make sure to inform your students before the lab visit that ankle-length trousers (made of solid fabric, similar to jeans) and sturdy, closed shoes must be worn in our teaching lab for safety reasons.
Leggings and tights are NOT considered safe pants in this case.
Please set a good example by following these rules yourself.
If the students' clothing does not meet above safety requirements, they cannot take part in the lab experiments.
The students can change on our premises, so there is no need to arrive in summer already wearing "lab clothes".
