Why is it important to test industrial dust?

Different types of dust have different risks, but those risks are not always visible. Some dusts are toxic when inhaled, with exposure limits governed by OSHA permissible exposure limits (PELs) — and without testing, facilities often have no reliable way to know whether those limits are being exceeded. Others may be combustible, presenting fire and explosion hazards that require evaluation under NFPA 660. Without testing, facilities are relying on assumptions that can lead to underestimating or mismanaging both categories of hazard. Understanding dust composition is the foundation for effective control strategies, accurate compliance evaluation and smarter allocation of safety resources.
