Spray rate cannot exceed 60 grams per second

You can carry pepper spray with you, but you have to respect certain conditions.

First off, when you carry the pepper spray around with you, it has to be concealed, and it also has to have a safety or something to prevent you from using it right away. In other words, you can’t carry it around in your hand ready to spray, or put it on your belt loop. If it’s small and looks like it could be a lipstick, I would probably recommend putting it in your pocket and having your hand on it.

There are three rules for using self-defense in France.

First, that you have to respond to the attack, which means that someone actually has to try to assault you or steal something from you before you can use the pepper spray legally. Otherwise, you’re the one doing the assaulting.

Second, you have to respond to an attack using “appropriate force.” France is no Florida, and you can’t shoot a man from behind because he punched you once or looked like he was going to. Don’t Stand Your Ground. You also have an obligation to try to run and get away if you can.

If someone attacks you with their fists, using the pepper spray or punching back would be an appropriate response, while shooting him wouldn’t be. And you can be accused of using “excessive violence” if you continue defending yourself once the attacker has been subdued.

Third, you’re only allowed to respond in the moment, and you can’t take revenge. So if someone steals your iPhone today, you can’t spray him when you see him next week. Just get the police.
