Acute pulmonary toxicity following occupational exposure to a floor stain protector in the building industry in Switzerland

Int Arch Occup Environ Health. 2004 May;77(4):244-8. doi: 10.1007/s00420-004-0505-6. Epub 2004 Mar 6.


Background: Waterproofing agents are widely applied to leather and textile garments; they are also used as floor stain protectors by professionals. Acute respiratory injury is described in three cases of young healthy adults following occupational inhalation of a new waterproofing formulation containing an acrylate fluoropolymer. Within 1 or 2 h after exposure they developed a rapidly progressive dyspnoea; two of them had hypoxaemia and flu-like reactions. All patients improved with supportive treatment in a few days. The mechanism of toxicity is still under investigation, but experimental data suggest the role of this new acrylate fluoropolymer.

Conclusion: Tilers should be warned against spraying floor stain repellents; there is also a need to make consumers aware that the spraying of waterproofing agents in a closed environment and concomitant smoking should be avoided.
