Safety

Physical Safety

If your project uses anything that might cause injury or is otherwise “dangerous”, such as controlling high voltages, using large high power motors, or driving potentially blinding light sources, you are NOT ALLOWED TO USE THE LCPF. Period. No “unless you pay for a commercial license”, no “unless you get permission”. No exceptions.

Please understand that this is NOT merely a “CYA” clause tacked on to the license. The LCPF is NOT designed for safety critical applications, and in some ways is incompatible with the safety-related patterns required to build them properly. Such applications require a level of rigor and discipline that is fundamentally at odds with the LCPF’s Primary Goal of making things easy for non-programmers, since building “safe” systems requires specialized knowledge that even experienced developers may not have.

The LCPF does incorporate things behind the scenes specifically focused on making things safer, so it’s less likely for you to break things in your project that it would be otherwise. However this only mimics some of the patterns used in safety critical systems - it does NOT fully implement them and is not a substitute for proper design and engineering. I mention this specifically to make it clear that while such measures may create an illusion of safety, it is still not even remotely enough for safety critical applications. So if you’re trying to build your own laser cutter¹ or add a powered exoskeleton to help you walk around in your W40K Space Marine cosplay¹, the LCPF is not for you (although I’d be happy to consult¹ on such a project about how to do it properly).

Psychological Trauma

Causing mental discomfort or temporary psychological trauma, such as a DM adding a bit of spice with terrain/miniature effects while springing a trap on their unsuspecting players is not only allowed, but sometimes encouraged.

Although please don’t give them “more than they’ve asked for” - you did cover expectations in your Session Zero, right? Specifically - you’ve established what subjects are expected and even anticipated, vs what are “off limits”?

I’ll probably never run an adventure with players having f**k fairie familiars, but that’s me. If you and your party want to go there, or extreme body horror, or Cthulu-esqe mind f**ks, or TPKs every few sessions, have at it as long as you’re all adults and you’ve got everyone’s consent in advance (and preferably a safe word). Unfortunately there’s no universal “adulting guide” that teaches everyone just how easy it can be to trigger someone else with seemingly “innocent innuendos” or topics that normal people wouldn’t expect to be threatening. Pulling out an owl bear could be disastrous if you didn’t know one of your players suffers from arkoudaphobia.

Role playing is an intimate thing - you can’t be safe and respectful of other’s boundaries if you don’t know what they are.
