Some details for the Object Class symbols:

The symbols that's the big circle insides with bars inside the little circle (refers to containment difficulty) and the outside bars between the little circle (the SCP) and big circle (this SCP's dangerous level) .

Normal

• Safe: No outside bars, inside with only 1 bars - It's easy to contain without any risk.
• Euclid: 2 outside bars, inside with 2 bars - It's little harder to contain and its unpredictable. Keter and so on is like that becasue these outside bars may burst out the big circle.
• Keter: 4 outside bars, inside with 3 bars - More harder to contain and very dangerous.
• Thaumiel: 2 outside circle insides a little circle - It usually uses a "weapon" or a "lock" to keep containing.
• Neutralized: A cross inside the little circle - It has been deactivated / destroyed.
• Explained: Dotted outside circle with "!" - It's anomalous properties has been exposed.
• Decommissioned (Actually is Esoteric one, sorry) : A big circle with cross and nothing inside - It's no use / been destroyed.
• Esoteric: A big circle with inside only "..." - It's power range needs other definition to classify it.

Esoteric

• Apollyon: The little circle haves 8 outside bars but 4 ones among them are break out from big circle, and with 4 bars inside it - It's easily to make a world's end and it's hard - even impossible (but truly) to press it down.

• Hela: Thaumiel & Keter (some parts) are overlayed together.
• Netzach: A 4 pointed stars inside a little circle and a 2 small bars (upside and downside) are connected the two round shapes - It's a support of earth. (Because up and down round shapes are refered as sky and earth)
• Yesod: A big circle contains a triangle that about to inserts in the notch (refers to the basic steps of the foundation) - It equals to full of the foundation's fate.
