No fear mongering needed.
Education works much better.
Nicotine can be purchased in many strengths. Safety precautions should be followed when handling straight nicotine Base, even in diluted form. Common sense things like NOT leaving bottles open or storing where children can easily come in contact.
Wearing plastic gloves and working on stable surfaces with absorbent material near by in case of spills.
If Nicotine solution is spilled, wipe it up and dispose of the rag/paper towels/etc.
If Nicotine solution gets on you, step to a sink and Rinse off.
I work with 100mg, have had the occasional incident and even gotten it on my arm. No ill responses, but I do clean up any accidental spillage immediately.
