The reduction of outdated industrial processes was a necessary editorial decision to make room for 21st-century hazards. introduces Cross-Laminated Timber (CLT) charring rates: 0
Fire departments are currently overwhelmed by fires in e-bikes, e-scooters, and electric vehicles. The 21st Edition contains new empirical data on thermal runaway, off-gas toxicity, and suppression strategies (including Class D extinguishers and immersion tanks). If you manage a warehouse, transit system, or office building with EV charging, this section is critical. Furthermore, at nearly 20 pounds for the set, it is heavy
