One of the most common questions asked by tradies requiring personal protective equipment is, what is the working life of a helmet? The answer to this question and indeed all information pertaining to selection, care and use is available in AS/NZS 1800:1998. This standard recommends that in general terms the helmet should be replaced every three years based upon industry testing, however to maintain the helmet, the complete head harness insert must be replaced every two years. Some customers elect to replace the entire helmet at this time or sooner dependent on its overall condition.
Every helmet has an issue date sticker on the inside of the helmet for the wearer to record their name and date of issue. Three years hence remove the helmet from use or earlier if the helmet has changed in colour, exhibits any signs of wear, or damage due to impact or deterioration (AS/NZS 1800:1998 3.4).
If the sticker has not been used, replace the helmet three years from the manufacture date stamp under the brim or peak of the helmet. In the centre of the stamp is the year with a direction arrow pointing to the month of that year in which the helmet was made.
The Scope of AS/NZS 1901:1997 standard specifies requirements for occupational protective helmets to protect wearers heads from falling objects in building and construction, quarrying, shipbuilding, forestry, and other industrial sectors with similar hazards.
These requirements include the construction, materials used ,mechanical strength and finish of both helmet shell and harness. All UniSafe helmet shells are made from premium impact resistant ABS plastic or polycarbonate.
In compliance with the standards objectives, specifying safety helmets is dependent on hazards involved. AS/NZS 1801:1997 classifies safety helmets into three types:
UniSafe Saftey helmets:
Type 1- General industrial safety helmets.
Type 2- Helmets intended for high temperature workplaces.
Type 3- Helmets intended for bushfire fighting.
