NENS09 2014 – What it is and what it means for you

I knew Energy Network Australia (ENA) Did you revise NENS 09? This month, changes to the national guidelines on the selection, use, and maintenance of personal protective equipment against electric arc hazards came into effect, including, among other things, what is considered “safe” to wear while working. Influence. This review brought the standard into line with testing and current developments in flame retardant clothing. This is great news!

So what does this mean for you?

We asked the managing director of Elliot’s, an expert in manufacturing Anthony Elliott To explain how these changes will affect the quality of safety equipment worn at work…

clothing or type of clothing

To date, protective clothing has been divided into two main categories.

  1. Primary protective clothing – change hood, coat/leggings, jacket, pants
  2. Secondary protective clothing – everyday work clothes, shirts, trousers, coveralls

However, the new NENS 09 2014 provides a higher level of detail regarding clothing types.

Therefore, I created a simplified table of NENS 09 clothing categories.

base garment

  • Base garments manufactured from arc-rated materials to be worn where exposure to incident energy greater than 5J/cm2 (1.2cal/cm2) is possible
  • Recommended minimum ATPV for baseware is 16.7J/cm2 (4cal/cm2).


  • Damage must not be aggravated in the event of an arc flash
  • Manufactured from at least 90% natural fibers

o Wool is very suitable as there is no risk of ignition.

o Unprocessed cotton is not suitable for basewear, but can be used for underwear.

So make sure you’re wearing the right base garment.

Remember: Never wear flammable, melting synthetic underwear.

winter outerwear

Thermal outer garments are garments worn over the base garment to provide thermal protection against cold ambient temperatures such as jackets and pullovers.

  • It is not mandatory that these garments be arc rated
  • Outer layer must be flame retardant according to ISO 14116
  • Must not have flammable molten synthetic layers or components
  • We also recommend thick wool knitwear and felted spun wool blanket fabrics.

IMPORTANT: Clothing that is not arc rated should

Do not rely on them to provide additional or enhanced arc protection.

arc rated outerwear

Arc rated clothing is worn when a higher level of arc protection is desired and should be worn over basic clothing.

These include:

  • coveralls
  • Switching between coat and leggings
  • Switch between jacket and overpants or bib and brace coveralls

Rainwear that does not mix water and electricity is designed to be worn over basewear.

Rainwear must be one of the following

  • Flame retardant according to ISO 14116
  • Or ASTM F 1891 or equivalent arc rating

Remember: Never use rainwear clothing that is not arc rated.

rely on to provide additional or enhanced arc protection

Also, rainwear should not be treated with additional products other than those specified by the manufacturer.
