{{distinguish|Swim bladder}} A '''pneumatic bladder''' is an inflatable (pneumatic) bag technology with many applications.
==Emergency management applications== Pneumatic bladders are used to seal drains and ducts to contain chemical spills or gases. Pneumatic bladders are often used for the containment of chemical spills, oil spills or fire water on water to prevent them from entering the environment, usually in the form of booms.<ref>{{Cite web | url=http://www.osti.gov/bridge/servlets/purl/663424-yo2o1P/webviewable/663424.pdf | title=Retaining latch for a water pit gate | archive-url=https://web.archive.org/web/20121003053413/http://www.osti.gov/bridge/purl.cover.jsp?purl=/663424-yo2o1P/webviewable/663424.pdf | archive-date=2012-10-03}}</ref>

<!-- Deleted image removed: thumb|left|Reef ball being deployed --> The Reef Ball Foundation uses a pneumatic bladder technology to float an artificial coral reef ("reef ball") into location, then deflate the bladder to sink the reef to the bottom.
==Other applications== Pneumatic bladders, known as dunnage bags, are used to stabilize cargo within a container.
Pneumatic bladders are used in medical research.<ref>{{cite journal | pmid = 2065148 | volume=27 | title=A pneumatic bladder array for measuring dynamic interface pressure between seated users and their wheelchairs | year=1991 | journal=Biomed Sci Instrum | pages=135–40| last1=Eckrich | first1=K.

Leading edge inflatable kites use pneumatic bladders restrained by a fabric case; the bladder is selected slightly larger than the case, so that at operational inflation the bladder is not stressed while the case defines the final shape of the leading edge. Many of the wing's airfoil ribs are similarly bladdered.
