Within our company, persons performing LOTO (interacting with breakers / disconnects) must wear PPE per the equipment label.
This creates a challenge when due to chemical exposure reasons, their footwear is limited to Neoprene boots.
Requiring operators to have a 2nd pair of safety shoes and then needing to switch shoes would be an issue as the MCC areas are within the production areas
Would leather spats typically used by welders be an acceptable covering?
The other thought is that the foot if the foot is outside the arc flash boundary, maybe we exempt the leather shoe but then if something happens,
everything falls down to the foot area.

The new NFPA 70E 2021 proposal on shoes will allow non-leather if it has been arc tested to assure no ignition of the shoe. ASTM F2621 now has a means to evaluate by arc shoes etc. My experience testing many neoprene and rubber boots has shown no ignitions but not sure what you are using.

www.ArcWear.com tests if your company wants testing or contact your boot manufacturer to see if they have tested.

I find it very interesting that some footwear manufacturers now carry tested AR shoes and boots which are constructed of non-leather uppers. At my facility we just implemented the requirement for leather footwear to be worn when arc rated PPE is required during the performance of any task where an arc flash hazard (by definition) may exist.
It looks like this provision for AR footwear may be permitted in 2021 when the next version of 70E has been released. We'll have to look into this as an alternative to only leather footwear.
However I was wondering why ASTM F2621 is not included in Table 130.7(C)(14)?
Thanks Hugh and hopefully we'll see you and Zarheer at the 2020 ESW in Reno.

I have a draft standard for testing shoes but it has not been submitted to ASTM F18. This takes time but NFPA 70E should address it and arc testing is ongoing for shoe manufacturers but they are not arc rated at this point, only tested for ignition.

See you in Reno!
