Under NFPA 660:2025, the requirements from two formerly separate standards, NFPA 664 (focused on wood processing and woodworking facilities) and NFPA 654 (covering a wide range of combustible dust applications not addressed by other standards) are now consolidated. By understanding and adhering to these essential requirements, businesses can create a safer. rolling exposure to respirable crystalline silica. Specifically, this sheet provides advice on the design of dust extraction uni ly appropriate protection and prevention measures. Choose the right box based on environment (indoor/outdoor), load capacity, and durability. Check for proper.
