Introducing the fire safety hood
The fabric is the increasingly popular 20/80 Nomex/Lenzing FR blend. Our new weight is 7.0 oz sq yd. in the traditional rib knit that now gives us 100% stretch. The unique characteristics of Lenzing FR, which is a derivative of wood, results in a TPP of 23.I at this lighter, more comfortable weight.
Because Lenzing FR Is a natural fiber, the fabric is both highly protective and very breathable.
The new hood styles are very close to the current Life Liners patterns. The FH33 uses the exact head pattern as the traditional Life Liners 23 hood. The bib is the same shape, and the back bib is sewn at the nape of the neck, which eliminates uncomfortable bunching. The front bib and shoulder seams are one inch shorter. This new hood’s overall size exceeds NFPA requirements. The new FH36 is the Life Liner 26 “tube pattern” and meets all NFPA requirements.
Both styles maintain the critically important head width which is a key requirement for a secure mask seal.
The bib edge
The bottom edge of the FH33 is secured with a tight, crochet stitch. This stitch is very similar to the stitch used to edge fine cloth napkins. It removes the traditional, bulky binding that makes it difficult to tuck in the bib after donning and eliminates it from getting caught on the coat’s upper closures. The key is that it is a tight stitch. It should not be confused with the sloppy, over lock stitch that has been attempted by competitors.
The Crochet Edge has been used by Nova Scotia Textiles, the dominant producer of hoods in Canada since 1992. It is widely preferred by wearers.
Not one failure has been reported in 18 years.
The FH33 use the Nomex label utilized by all Life Liners hoods. The label is sewn to the hood on all four sides to keep it securely attached to the hood even after repeated use and washings.
Sewing the label on all four sides helps insure traceability and accountability.
All seams joining the fabric components are sewn with stronger flat lock stitching, replacing the double sewn seam which digs into the head when the helmet is tightened.
