If the SCP actively attempts to chase down the player, it's Hostile.
If the SCP can only harm the player indirectly or will only harm the player due to a player's own choices, it's Hazardous.
If the SCP does not effect the player, it's Harmless.
If the SCP can help the player, even if it is harmful if used wrong, it is Helpful. This does not count if it can only help through modification through SCP-914 or the like.
If the SCP is no longer in the game, it's Removed.
If the SCP is registered as a joke on the official SCP wiki, it's a Joke, regardless of actual function.
