here are some paragraphs from a blog i found. please stay safe!!
major arteries, stay away from them
“Know where your major arteries and veins are, and be sure not to cut over them. It’s best to avoid cutting near them altogether, if possible.”
“Be aware of where you cut, as it will leave visible scars. Self-injury is often criminalized, and fresh cuts can lead to involuntary hospitalization in some cases.”
“Be aware of the material your blades are made out of if you have metal allergies. Most blades are made with stainless steel to my knowledge, but it never hurts to check.”
first aid supply list
"Some of these may not be available to everyone, however it’s a good idea to try and have some around if cutting is something you do often.
Bandages (including elastic bandages)
Antiseptic (bactine or 70%+ isopropyl alcohol are suggested. iodine can be used if nothing else is available, but be aware that they induce scarring and increase healing time. also if possible, rinse with warm water, and wait a day or two then wash it with soap as well.)
Clean blades, non-serrated, preferably single-edge."
crisis situation first aid steps
"Sometimes, severe cuts or other injury can cause your body to go into hypovolemic shock. Shock is life threatening and can kill you. If you think you are going into shock, call an ambulance. Shock tends to make itself worse, so it is critical to get medical attention quickly.
Symptoms of shock may include:
confusion, restlessness & irritability
dizziness, faintness & nausea
pale, clammy, moist skin
cold & mottled skin, especially in extremities
rapid, weak pulse
Control external bleeding (see below)
Try to maintain body temperature. If you notice you are experiencing hypothermia, try to cover yourself with a blanket or something similar.
Do not eat or drink, even if you feel thirsty which will be likely.
Do not raise your head.
If possible, try to keep your legs elevated about 12 inches.
If a cut won’t stop bleeding, first try pressing cloths, paper towels, or any sort of substitute bandage directly on top of the wound. Then, place a large object (like a balled-up sock) over the bandage, and wrap the entire thing tightly in an elastic bandage (or, if not available, gauze). Keep the wound above your chest and check in about 10-15 minutes. If it’s still bleeding, re-wrap it and go to an emergency room.
Infected cuts are a big risk should you be unable to keep cuts or wounds clean. This applies to small cuts and wounds just as much as larger ones that may need stitches. That said, infection can be easily avoided under most circumstances.
If a cut or wound is infected, it will likely show some of the following:
Drainage & Pus
Local Fever (meaning that the cut will feel hotter than areas around it)
Increased or Sustained Pain
Should an infected wound go untreated, it may end up becoming a full-body infection, which can cause serious problems and needs immediate medical attention. Warning signs for a full-body infection are:
Fever (over 100°F)
Those with decreased immune function should take extra care to prevent infection as you will be at higher risk. It is important to change wound dressings (bandages, cloth, etc.) daily, and wash your hands and the wound before touching the wound or applying dressings each time. If a wound gets infected, try to find antibiotic ointment of some kind (which you can get at most drug stores or some supermarkets.) If you develop a full-body infection, oral antibiotics should be taken (unless you have an allergy or they will cause complications for you). That said, it really is best to see a doctor or go to the emergency room in this case, but I also know that far too often it’s just not feasible, especially without a stable income, housing, or insurance. So please, take care of yourselves and don’t let something go too long without help if you can help it."
again, you really shouldn’t cut. it’s not safe, no matter how many precautions you take
