For your safety, I always keep a first aid kit and emergency tools nearby. For rope, titanium EMT shears and a marlin spike. For electricity, rubber gloves. For fire, antibacterial ointment and burn gel. I try to always be prepared for the worst-case scenario and take as many risk mitigation steps that my experience and education have taught me.
As far as training, I have CPR experience, emergency first aid training (combat related, not medical), experience handling life threatening dangers and complications, and a calm demeanor in hard situations. I am not a medical expert, but I respond to emergency situations with experience, intelligence, and composure.
This is a difficult question to answer outright. There is no certification tests, evaluations, or many institutions who provide skill based examinations, so I cannot validate my skills in that manor, however I do have references that can speak to both my education, experience, skills, and ethical professionalism. Additionally, I am trying to provide as much information about my talents and skills as well as visual documentation of said skills. I am also more than willing to talk shop and get into the technical and safety aspects of whatever skills I advertise I have. Your safety is alwasy my top priorty and trying to make this community a safer place and more knowledgable place for everyone is the whole reason I began this journey into kink.
You would certainly not be alone in that sentiment! Many people want photos and would enjoy seeing them being posted, but get nervous that someone might recognize them or just generally like their privacy. Like you, I value privacy and consent and would never post your photo without consent. Furthermore, I have the ability to crop and blur distinguishing features if you so desire. Always feel free to communicate EXACTLY what you want and are comfortable with, you aren't hurting me more my busniess by protecting yourself!
