This is a Sources Sought notice. This is not a solicitation for proposals, proposal abstracts, or quotations. The purpose of this notice is to obtain information regarding the availability of small business sources to meet the requirement. The National Institutes of Health (NIH) is seeking to obtain information regarding:

(1) the availability and capability of qualified small business sources;

(2) whether they are small businesses; HUBZone small businesses; service-disabled, veteran-owned small businesses; 8(a) small businesses; veteran-owned small businesses; woman-owned small businesses; or small disadvantaged businesses; and (3) their size classification relative to the North American Industry Classification System (NAICS) code of 315990 with 500 in size standards in number of employees for the required bio-safety level 4 (BSL-4) positive pressure suits.

Due to the nature of work performed in high containment laboratories, BSL-4 positive pressure suits are necessary for the safety of the researchers.

The BSL-4 positive pressure suits must be made from a material that is resistant to daily quaternary virucidal chemical showers.

Each suit must include an in-line HEPA filtration system that connects to a facility provided breathing air system via standard Parker quick connections. The suits must use the air provided at 60 PSI and utilize an internal suit air distribution system to deliver 25 cfm that is HEPA filter exhausted. Air hose hook up shall be on the right side. All seams shall be air and watertight.

The suit’s feet must be stocking type that will fit into a shoe or boot; and noise level inside the suit must be below the OSHA standard (OSHA's permissible exposure limit (PEL) is 90 decibels) and allow clear communication over radio or phone by the user while in the suit. An organization that is not considered a small business under the applicable NAICS code should not submit a response to this notice.

Any potential offers should respond with their capability statement by 1:00pm eastern standard time (EST), Friday, May 8, 2026, in writing by email to Tonia Alexander at tonia.alexander@nih.gov with (subject line to reference SS-75N98026Q00250).
