Quick answers
Is Wood non-combustible?
Declared reaction class in this atlas: D–B depending on product / treatment. Assemblies still need resistance tests.
Does Wood insulate?
Thermal mark 56/100 versus the atlas. Conductivity note: ~0.1–0.2 W/m·K along vs across grain.
What is the density band?
0.3–0.8 g/cm³ typical
How is it made?
Origin story: Palaeolithic tools; CLT 1990s Austria (Global forests / Graz).
Can it be recycled?
Circularity mark 76/100 — editorial, route-specific.
Typical melting or failure heat?
chars ~200–300 °C; does not melt

Safety here is encyclopedia, not a workplace assessment. Name the agent: dust, isocyanate, fibre, fume, moisture, fire.
Fire class D–B depending on product / treatment is reaction language unless an assembly test is cited.
Hazards
In service
Corrosion, moisture, UV or creep silently retire sections.
Fire products
Smoke, drip, fibres or toxicants depend on chemistry.
Cut / puncture
Handling injuries are more common than brochure failures.
Mis-specification
The wrong grade is the most expensive hazard.
Fire class
Reaction
D–B depending on product / treatment
Resistance
Assemblies (EI, R, Type X) are not implied by the material letter.
Test families
EN 13501, ASTM E84, ISO 5660, KS F 2271 — they do not equal each other.
People vs structure
Clothing FR and steel R-ratings are different professions.
Environment
Carbon / energy
Better-than-average loop for this atlas, still not zero.
Toxics / fibres
Additives, dusts and processing aids (not always the polymer backbone) drive regulation.
Water
Process water, leachate or moisture swelling.
End of life
Sortability beats theoretical recyclability.
Handling
Store dry and labelled
Grade mix-ups scrap lots.
PPE for the actual agent
Fibres, isocyanates, UV, sharp edges — not a generic “chemicals” pictogram.
Do not improvise fire class
Coatings and cavities change the letter.
Follow the WPS / DFT / compression
Installation is in the specification.
Codes move. Recheck KS, JIS, EN, NFPA and IBC editions for the job’s jurisdiction.
