Toxicity from fluoropolymer-containing grout, tile and stone floor sealants reported to the UK National Poisons Information Service 2009-2015.

CONTEXT: Grout, tile and floor stone sealants contain a solvent, a water-repelling agent and in the case of aerosols a propellant. The water-repelling agent used is typically a fluoropolymer resin, a silicon-based resin, or a combination of both. OBJECTIVE: To report the clinical course in patients exposed to fluoropolymer-containing sealants referred to the United Kingdom National Poisons Information Service. METHODS: A retrospective analysis was performed of telephone enquiries received between 2009 and 2015. RESULTS: 101 enquiries involving 96 exposures were received. The majority of the exposures (n = 88) occurred when the sealant was delivered from an aerosol. Twelve patients were exposed occupationally and the remainder were exposed while using the product at home. Eighty-nine exposures were as a result of inhalation alone, two followed ingestion, three skin contact and one eye contact; one involved inhalation and eye contact. All 90 patients exposed by inhalation developed clinical features: 31 had a World Health Organisation/International Programme on Chemical Safety/European Commission/European Association of Poison Centres and Clinical Toxicologists Poisoning Severity Score of 1 (minor toxicity), 51 patients had features of moderate toxicity (PSS 2) and eight were graded PSS 3 (severe poisoning). The most common features were dyspnea (n = 52; 57.8%; 95% CI = 47.0-68.5), chest pain/tightness (n = 34; 37.8%; 95% CI = 27.2-48.4), coughing (n = 27; 30.0%; 95% CI = 20.0-40.0) and sinus tachycardia (n = 11; 12.2%; 95% CI = 4.1-18.2); hypoxemia was present in 20 (22.2%; 95% CI = 13.1-31.4). At the time of the enquiry a chest X-ray had been performed on 15 patients: in eight patients (all of whom were PSS 3) the X-ray was reported as being abnormal and showed bilateral shadowing. CONCLUSIONS: This study demonstrates that if fluoropolymer-containing sealants are inhaled then clinical features may occur and in a small proportion (9%) these features may be severe.

Acute noncardiogenic pulmonary edema due to polymer fume fever.

BACKGROUND: Certain fluorocarbon polymers can produce a clinical syndrome called polymer fume fever when the products of pyrolysis are inhaled. SUMMARY: A previously healthy 21-year-old white man presented with severe chest tightness, difficulty in breathing, pyrexia, nausea, vomiting, and a dry irritating cough. These symptoms occurred suddenly while smoking a cigarette 2 hours after leaving his place of work, where he is a plastics machinist. A chest roentgenogram revealed a bilateral patchy alveolar air space filling pattern involving the mid and lower lung fields. The diagnosis of polymer fume fever was established on the basis of the symptom complex, the association with cigarette smoking, and the occupational exposure to micronized polytetrafluoroethylene. CONCLUSIONS: A thorough occupational and smoking history is necessary to recognize polymer fume disease, which may resemble influenza.

Toxic alveolitis after inhalation of a water repellent.

Inhalation of fluorocarbon polymers can cause pulmonary toxicity. Although multiple cases of lung injury have been reported, cellular characterization of the associated alveolitis occurring acutely after inhalation is limited. We report the case of a previously healthy woman who presented at our Emergency Department with an acute pneumonitis following inhalation of a fluorocarbon polymer-based rain-proofing spray. Bronchoalveolar lavage (BAL) performed shortly after the presentation showed an elevated total cell count, with a high proportion of neutrophils (58%) and eosinophils (9%). In addition, a lipid stain (Oil-Red-O-stain) showed a high level of lipid laden macrophages, a marker that could reflect a direct toxic effect of the spray on alveolar cells. The patient made a full recovery after four days of in-hospital observation with supportive care.

[Polymer fume fever[]. / Polymerrøykfeber.

Polymer fume fever is a self-limiting condition with influenza-like symptoms (fever, headache, dry cough, dyspnoea and myalgia). It is caused by inhalation of toxic products released by combustion of fluoro-carbon polymers. There is no causal treatment, and the symptoms usually clear up spontaneously within 24 hours. This article describes an accident where 13 soldiers became ill when exposed to fumes released from a tent oven painted with a coating containing fluoro-carbons.

Death due to fluorocarbon inhalation.

The abuse of inhalation of aerosol preparations containing fluorocarbons as the propellant is a potentially lethal act. I report a death believed due to inhalation of an aerosol propellant.
