Further Information - FR Disposables and Repellency
FR Disposable garments and Repellency
FR Disposables are intended to be worn over Thermal Protective Garments (TPG's - certified to standaed EN 11612). They are tested to the simple vertical flammability test in EN14116 (see summary here) or download our guides to FR Disposables: Full Guide here and "In Brief" Guide here) which provides only very limited information about real FR Properties and is innadequate in testing FR SMS materials.
However, what happens to these garments in actual use? During wearing they will commonly be splashed and contaminated - often with liquids which might be flammable - such as oils. This would eb common in the petrochemical industry where such garments are used. SMS fabrics have poor replleency against oils and are likely to absorb them more readily.
This can then affect their flammability properties so that regardless of how they might react to a flame when dry, the result when contaminated will be unexpected
Lakeland have conducted testing of fabrics both for repellency agains oil AND for vertical flammability. The results can be seen in the a video on You Tube. Click the picture to the right or click here.
View the video and decide for yourself whether you would prefer to ttake the risk of wearing FR SMS... or Pyrolon...
(Note: The video does refer to some North Anmerican NFPA tests, but the repellency and flammability test videos are self explanatory... and startling...)
