Process energy / dust
Mills, fibres, isocyanates, metal fume or silica — name the actual agent.
Carbon fibre · Polymer-derived filaments with graphite-like sheets — aero, bikes and a fire story that is about the resin, not the fibre.
Safety here is encyclopedia, not a workplace assessment. Name the agent: dust, isocyanate, fibre, fume, moisture, fire.
Fire class fibre A1-ish; CFRP follows the matrix is reaction language unless an assembly test is cited.
Mills, fibres, isocyanates, metal fume or silica — name the actual agent.
Corrosion, moisture, UV or creep silently retire sections.
Smoke, drip, fibres or toxicants depend on chemistry.
Handling injuries are more common than brochure failures.
The wrong grade is the most expensive hazard.

Assemblies (EI, R, Type X) are not implied by the material letter.
EN 13501, ASTM E84, ISO 5660, KS F 2271 — they do not equal each other.
Clothing FR and steel R-ratings are different professions.
Primary production is energy-heavy; ask for a route, not a slogan.
Additives, dusts and processing aids (not always the polymer backbone) drive regulation.
Process water, leachate or moisture swelling.
Sortability beats theoretical recyclability.
Grade mix-ups scrap lots.
Fibres, isocyanates, UV, sharp edges — not a generic “chemicals” pictogram.
Coatings and cavities change the letter.
Installation is in the specification.
Codes move. Recheck KS, JIS, EN, NFPA and IBC editions for the job’s jurisdiction.
A one-atom carbon sheet — Nobel-era physics, composites hype, and a few honest electronics and barrier uses.
Overall 50 ☁️A nanoscale silica sponge — among the lowest solid λ values, fragile unless blanketed, and A1 when purely inorganic.
Overall 60 🩺Near-equiatomic Ni–Ti that remembers shape and super-elasticates — stents, orthodontics and actuators.
Overall 48 ☀️ABX3 halide crystals that jumped laboratory solar efficiency — still fighting humidity, lead and lifetime.
