Process energy / dust
Mills, fibres, isocyanates, metal fume or silica — name the actual agent.
Пенополиуретан · Органическая пена с низким λ для холодильников и зданий. Пожар — про PIR и облицовку.
Safety here is encyclopedia, not a workplace assessment. Name the agent: dust, isocyanate, fibre, fume, moisture, fire.
Fire class typically E–B with facers; not A1 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.
typically E–B with facers; not A1
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.
