It seems straightforward enough, but something a lot of people don’t think about until it’s too late is first-aid kits. Every dungeon should have one; in fact, every playroom should have one. I have one in my laundry room in case we have issues at any of my house parties, and I keep a small one in my play bag as well. BDSM is inherently dangerous, even when done correctly, and it’s vitally important that you are able to ameliorate a bad situation so you don’t have to call 911 (in the US) and get everyone out of their headspace.

According to AI:

A good dungeon or wilderness first aid kit must prioritize trauma care and infection prevention for deep cuts, punctures, splinters, and burns. Key items include a tourniquet, hemostatic (blood-stopping) gauze, nitrile gloves, antiseptic wipes, antibiotic ointment, trauma shears, tweezers, blister treatment (moleskin), and various sizes of bandages, all kept in a waterproof container. 

Essential First Aid Kit Items

• Wound Care & Trauma (Priority): Hemostatic gauze for heavy bleeding, trauma shears (blunt-tip) for cutting clothes, antiseptic wipes/spray, triple antibiotic ointment, assorted gauze pads (4×4), and a roll of conforming gauze.
• Tools & Protection: Nitrile gloves (non-latex), tweezers, safety pins, duct tape (versatile repair/splinting), and a small, sharp knife or multi-tool.
• Blisters & Skin: Moleskin or hydro-colloid blister plasters (crucial for long treks) and hydrocortisone cream for itching/stings.
• Bandages & Tape: Assorted adhesive bandages (various sizes), athletic tape (1-inch), and butterfly closures/Steristrips for sealing large cuts.
• Medications & Other: Pain relievers (ibuprofen/acetaminophen), antihistamines (Benadryl), aspirin (for potential heart incidents), and burn gel.
• Optional/Advanced: Emergency blanket, irrigation syringe, Sam splint, and antiseptic wipes. 

Preparation Tips

• Waterproofing: Store everything in a Ziploc bag or a dedicated waterproof container.
• Accessibility: Place the kit in an easily accessible area of the backpack.
• Knowledge: Include a small first-aid manual or quick-reference guide. 

That all seems pretty reasonable.

My play bag first aid kit contains Tegaderm, Band-Aids, triple antibiotic ointment, and liquid skin. That’s usually all I need because I’m just doing a spanking scene and it’s rare that I break someone’s skin. However, it has happened (I have a play partner I see about twice a year to whom it happens about 50 percent of the time) and it’s always good to have supplies on-hand.

Keep the first-aid kit somewhere in the dungeon where everyone can find it and access it as needed. Tell everyone where it is. If you don’t know, you can’t use it.
