There are no rules in a street fight. The goal is to act first and prevent further risk.
Sprays and chemical deterrents may give you a bit of time to put some distance between you and the person you are spraying but may not put the person down and and out for the count. If they have a firearm, you can pretty much bet that if they can't see, they'll be firing in every direction and they only need to get lucky once.
A taser that shoots barbs would be preferable to a spray. If you don't have an offensive weapon to engage a target at distance, you really need to consider your options before stepping closer to potential trouble. In your home, a bat swung with maximum force as someone comes around a corner or through a doorway has a better chance of success than confronting someone at "close range" while in plain view holding a can of bug spray.
Anything is better than nothing, but most handheld common items fall far short of ideal and only offer a marginal increase in personal safety in a direct confrontation.
