- OSHA Permissible Exposure Limit (PEL):
- American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV): 10 mg/m3 TWA
- National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 10 mg/m3 TWA
- Potential Symptoms: Irritation of eyes, skin, mucous membranes; blocked nose, dry nose, sneezing; hoarseness, cough and phlegm; exercise-induced dyspnea
- Health Effects: Nuisance particulate (HE19)
- Affected Organs: Eyes, skin, respiratory system
- Cellulose dust is combustible, and under certain circumstances may represent an explosion hazard (see OSHA, 2005).
- Exposure of insulation installers to both cellulose dust and cellulose fibers has been studied, and the exposure risk was found to be high for loose-fill materials.
- Exposure of workers in soft tissue paper manufacturing in Germany to inhalable dust was considered high (means, 10.3 and 12.4 mg/m3), whereas exposure to respirable dust was much lower (means, 0.22 and 0.28 mg/m3). Thus, most significant symptoms involved the upper respiratory tract, although pulmonary function parameters (FVC and FEV1) also decreased with increasing exposure.
- Workers involved in the manufacturing of cellulose from raw materials, such as reeds or cotton [see Cotton Dust (Raw)], may also experience respiratory symptoms related to exposure to irritating dust.
