Australian Fire Rated Sock Technical

Sock ImageThe Australian manufactured specialist Fire Rated Sock is a state of the art, comfortable, three layer
wool/nylon/wool garment incorporating a fire resistant finishing process to provide unparalleled protection for the wearer. The Fire Rated Sock has been designed using a unique three layer construction method. In manufacturing the sock, the treated wool is knitted on the outside, a nylon mesh panel is knitted in the middle and pure wool in a terry padded format is knitted on the inside. The top welt of the sock is pure wool.



Tasmanian Merino Wool

Tasmania - where the world's most precious Merino Wool is grown.

Grazing in free wide open spaces, breathing the purest of air, Tasmanian Merinos produce a magnificent high quality Wool, offering whiteness, strength and soft touch.

Tasmania is renowned for its uniquely pure, Wool growing environment. The Tasmanian Merino brand offers authenticity and credibility to environmentally sensitive and ethical Merino Wool production.





The garment is designed for use in environments where there is risk of burn injury from flame, extreme heat and ignition or where molten metal can penetrate protective work wear or enter protective footwear. The garment is Australian made and has been tested for resistance to molten aluminium (780° C) and cast iron (1400° C) and ease of ignition and protection against flame. The test time for ease of ignition and protection against flame exceeds 20 seconds.


Wearer Tip – as an alternative to wearing the garment fully extended to just below the knee, wear as a loose fit and roll the garment down over the top of the smelter/work boot. Doing so creates a seal around the top of the boot.

How to Avoid Blisters

Blisters on the feet occur when the foot moves or 'slides' inside the boot. This is common in rubber boots, which are not made to fit snug like regular footwear. Added to this problem is the fact that our feet usually perspire when encased in rubber or regular work boots, especially in warm or hot climates. This tends to keep the skin on the feet soft rather than calloused. The friction of the foot rubbing against the inside of the footwear will wear the skin producing a blister.

There are a number of ways to reduce the possibility of blisters on the feet. One of the easiest ways is to 'double sock', which involves using a polypropylene sock liner inside either a Wool or Cotton blend sock. Polypropylene is a man-made fibre, which 'wicks' or draws moisture away from the skin. The other or main protective sock should be a Wool or a Cotton blend sock, which will allow moisture to evaporate. Nylon, Orlon or other man-made fibres do not allow for airflow like a natural fibre, so they tend to stay wet. Wool retains its warmth even when wet while Cotton will start to feel uncomfortable if it becomes wet in cold conditions. Socks are usually manufactured in different thicknesses so choose a sock for your work boot which helps to take up some of the excess room inside the boot.
