Decide Wood from the 300 ignition shorthand note and the figure 300 in Safety & fire class. Use Steel in Safety & fire class only as contrast. A shopping guess that drops 300 does not replace the dossier you can already open.
Atlas Verification Checklist
0 / 4 verifiedCheck each criteria to confirm findings against the atlas verdict.
Open the existing chapter · Wood / ignition shorthand (300)
Open the Safety & fire class chapter of Wood and write 300 beside 300 on the ignition shorthand note before you accept a shopping guess. A figure that leaves that chapter is no longer the basis of the decision you can defend.
Keep the figure attached · Wood / ignition shorthand (300)
Keep 300 attached to Wood and to the ignition shorthand note in Safety & fire class. If a shopping guess moves the figure onto Steel or onto a different year, put it back on the page that already exists.
Stay inside the limit · Wood / ignition shorthand (300)
This is a heat, fire, or flex decision, not a shopping list, and alloy or code can move the safe choice. The ignition shorthand note is a way to read Wood around the figure 300. It does not add a method, a rank, a cure, or a promised result beyond that page.
Use the second page as contrast · Wood / ignition shorthand (300)
Open Steel in Safety & fire class only to see a different existing page. Do not let that page supply missing facts for the 300 ignition shorthand note on Wood. Two dossiers side by side are still two dossiers.
This is a heat, fire, or flex decision, not a shopping list, and alloy or code can move the safe choice. Check 300 on Wood in the Safety & fire class chapter before you act on a shopping guess.
Does the ignition shorthand note replace the Wood dossier?
No. The note tells you to read the Safety & fire class chapter of Wood first and to keep 300 beside 300. The dossier remains the source.
Can Steel override the figure 300?
No. Steel is only a contrast in Safety & fire class. It cannot erase 300 on the ignition shorthand note.
What if a newer shopping guess ignores 300?
Keep both dates. A later shopping guess does not delete 300. Return to the Safety & fire class chapter and write down the clash instead of keeping the louder version.
