Within many subjects it is expected that certain content will inevitably include triggering themes. Whilst students can mentally prepare themselves to encounter triggering content in a general sense by understanding the topic they signed up to study, they are not able to discern when in a module the triggering content may appear. For instance, the lecturer may include a general disclaimer in the module handbook stating that themes of sexual assault, suicide and rape may come up during the module, but they do not indiciate specifically within what set reading/video/source material this will happen. A student might then unknowlingly watch an incredibly violent/graphic scene from a film or documentary, which they otherwise may have chosen to avoid. 

To be clear, this is not a request for all content to come with trigger warnings, nor is it a naive attempt to establish 'safe spaces' and 'bubbles of protection,' this is merely about ensuring students with past traumatic experiences are not caught off-guard.
