Process energy / dust
Mills, fibres, isocyanates, metal fume or silica — name the actual agent.
Safety here is encyclopedia, not a workplace assessment. Name the agent: dust, isocyanate, fibre, fume, moisture, fire.
Fire class system-dependent; core often A1-ish, skins not is reaction language unless an assembly test is cited.
Dangers
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.
Classe feu
Reaction
system-dependent; core often A1-ish, skins not
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.
Environnement
Carbon / energy
Primary production is energy-heavy; ask for a route, not a slogan.
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.
Manipulation
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.
