N5a Vs N6a: a Detailed Comparison
Now that you’re ready with the overview, let’s provide you with the details! The elaborated comparison of the key factors is given below. Give it a good read!
The plastic insert of a cap is the impact cap of a helmet, which protects against impacts.
For the N5a there is an impact cap double-layer protection. The double layer of protection can withstand a decent amount of impact.
While 2 layers of protection are great, it’s still lesser than the upgraded version, the N6a. Although, the N5a does have an optional 6” front holder, which diverts energy from the head/neck area.
The N6a has 3 layers of impact cap protection, which makes it more resistant against impacts. In comparison, the impact will be dampened in the N6a more than the N5a. Similar to the N5a, the N6a also has an optional feature of a 6” front holder.
The impact caps of these helmets provide significant thermal protection and penetration protection. Additionally, both helmets have Nomex/PBI/Kevlar earlap neck and ear protections as well.
Summary: Between the N5a and N6a, N6a has more impact cap layers and protection than the N5a.
Fire helmets can be multipurpose helmets. However, not all of them are multipurpose.
The N6a helmet’s application is only for firefighting. This helmet does not follow any other applications.
On the other hand, the N5a has 2 applications. With the N5a helmet, you can join in firefighting or search and rescue protocols. N5a follows all the necessary rules to abide by these 2 protocols.
As you can tell, fire hazards are quite dangerous. To prevent fire hazards and damage, you can install fire alarms in your building/house.
So, prepare a budget for the fire alarm and the inspection cost of fire alarms to prevent fire hazards!
Summary: When it comes to having more than one application, N5a’s better than N6a for having 2 applications.
Knowing the approvals of fire helmets is important because it helps to determine the certifications of the helmet.
The N5a has OSHA approval (Occupational Safety and Health Administration). OSHA approvals ensure healthful and safe conditions.
On the other hand, the N6a has NFPA approval (National Fire Protection Association). NFPA is part of OSHA and ensures non-risky electrical and fire hazards.
Summary: In terms of standards and approvals, the N6a has NFPA approval whilst the N5a has OSHA approval.
Face Shield and Chinstrap:
Having a face shield and chin strap on a fire helmet are necessary. Face shields help protect the eyes against impacts while chinstraps make sure the helmet stays in place.
Fortunately, both the N5a and N6a have face shield and chinstrap options! The face shield has a non-corroding high-temperature glass.
Moreover, the chin straps are made with soft black Nomex, which features a one-hand quick-release option. This increases efficiency by reducing the time taken to take off the helmet.
Speaking of saving time, in the case of fire hazards, don’t forget to use the emergency staircase. The emergency lights stay on so that you can always find the staircase!
Summary: The N6a and the N5a have face shield/goggles and chinstrap options available.
Every fire helmet has different sizes available for different users. The more versatile the sizes are, the better the chances of a good fit!
The Cairns N6a helmet has two sizes available. The first one is medium size and the second one is large. The size of the medium helmet ranges from 6-⅜ to 7-½. The large helmet’s size ranges from 7-⅝ to 8-⅜.

All of the colors here abide by OSHA and NFPA approvals. Both professional firefighters and volunteer firefighters can get paid by using any of the base 8 colors.
Summary: There are a total of 8 colors available for both the N5a and N6a helmets.
The weight of fire helmets counts a lot! In rescue missions, the helmet needs to be put on for extended periods. The lighter the fire helmet, the better.
The weight of the N6a is 4.623 lbs. This does fall in the average weight of fire helmets, which is between 3 to 5 lbs. However, it’s the heavier option between the N5a and N6a.
On the contrary, the N5a is the lighter option in comparison. This fire helmet weighs 4.409 lbs. While the weight difference is minimal, the reduced weight helps a lot in missions!
Summary: The N5a is the lighter option when comparing the N5a and the N6a helmets.
Fire helmets are one of the costliest helmets as their production is costly as well. But cost does have less precedence than safety!
The N6a comes at 2825-2830 dollars. It is the more expensive helmet in comparison. You can buy this helmet from different safety companies throughout the USA.
On the contrary, the Cairns N5a fire helmet costs 2650- 2660 dollars. It’s almost 200 dollars cheaper than its successor, N6a. Featurewise, the N5a does offer a lot in its price point!
