This article crossed my desk yesterday and I won't even paraphrase it or change it all, but will just provide the link.
This is a new construction technique that involves a pre fabricated staircase with multiple gusset plate connectors.
Please pass this important safety bulletin throughout your department.
The I Stair at Green Maltese Website
Also if you have not already heard about the Green Maltese or do not have their page bookmarked, please do so there is great information on their website!
Thanks and stay safe!
