Research into the potential health effects of exposure to RCFs has involved both animals and humans, with significantly different results 3 . Unlike the animal results, a study of about 1,500 current and former RCF manufacturing employees has not identified any incidence of RCF-related lung disease. The PSP also demonstrated that engineering controls, process improvements and proper handling techniques are effective means of controlling airborne fiber and reducing exposure risks. RCF materials present little, if any, opportunity for exposure if handled in an encapsulated form. RCF hearth products are typically encapsulated and should fit most applications without modification.
Power tools generate significantly more airborne dust.
Wash exposed skin with soap and water after handling. Launder RCF-soiled clothing separately. When HEPA-filter vacuums are not feasible, lightly spray RCF materials and work area with a water mist before sweeping or bagging of debris. Do not use compressed air to clean work clothes or work area. Refrain from smoking, eating, or drinking while working near areas where RCF-containing dust is present.
