This Request for Quotation (RFQ) aims to secure a single award firm fixed-price order, with a delivery timeline of 60 days from the date of award, ensuring timely access to essential safety equipment. The SCSR units are critical for ensuring the safety of personnel in industrial environments, particularly in mining operations where emergency self-rescue capabilities are paramount. Interested vendors should direct inquiries to Rose Goodwin at goodwin.rose@dol.gov or Alicia M. Jackson at Jackson.Alicia.M@dol.gov, with the understanding that this opportunity is set aside for small businesses under the SBA guidelines.
