DONT KEEP YOUR PEPPER SPRAY ON YOUR KEYS
Carrying pepper spray without proper training is dangerous in and of itself due to the fact that if you don’t know how to use it you can be effectively giving your attacker a weapon to use against you (same goes for if you’re carrying a knife and aren’t trained on how to use it)
But if you MUST carry pepper spray DO NOT KEEP IT ON YOUR KEYS because if and when your attacker grabs it from you they will effectively have obtained your car and entrance to your home and your student ID and whatever else you keep on your keys.
Also you make it 10x easier for your attacker to grab your pepper spray from you if it’s attached to a lanyard.
Common sense people. Please.
