The 125 Fighter Wing, Florida Air National Guard in Jacksonville, FL, is conducting market research through a Sources Sought notice to determine whether responsible sources exist for Halon fire extinguisher inspection services on 33 Amerex model 600K, 150-lb Halon extinguishers. This is not a request for proposal, quotation, or bid and does not obligate the Government to award a contract.

The applicable NAICS code is 811310, with a $12.5 million size standard, and the notice will help determine the appropriate small business set-aside category. Interested contractors should respond electronically with the attached cover sheet plus up to five pages covering company/CAGE and small-business status, up to two similar past-performance examples with contract and dollar values, and relevant capabilities; SAM registration is required for award eligibility.
