Personal Protection sprays are very handy in situations where the attacker is within 4-5 feet. Such sprays spray chemicals like Pepper, tear gas or similar irritants. These are sprayed towards the attackers nose/eyes with immediate effect. Such sprays come in containers like those used for Perfumes or some are even in shape of a pistol.

Normally, such sprays produce lot of burning and impairs the vision or leads to constant coughing for 10-15 minutes.

These must be used with caution and never to be used as a prank.Though in some cities the Police itself is promoting the use of this for protection against eve-teasing but you are well advised to check with your local police station for it's legal implications.
