Floating oil booms are specialised containment barriers designed to control, contain, and isolate oil and fuel spills on water. They float on the surface to prevent hydrocarbons from spreading into stormwater systems, harbours, lakes, ponds, and marine environments.
What Floating Oil Booms Are Used For
Floating booms are essential for:
Containing oil and fuel spills on water
Protecting stormwater drains, ponds, and waterways
Creating barriers around boats, marinas, and slipways
Isolating spills during fuel transfers and refuelling
Responding to hydrocarbon leaks from machinery near water
Preventing spread of oil during rain events
Emergency response in harbours, lakes, and retention ponds
Floating booms are the primary containment tool for any spill that reaches water.
How Floating Oil Booms Work
Floating booms use a combination of:
A buoyant top section that keeps the boom afloat
Hydrophobic absorbent material that attracts and absorbs hydrocarbons
Interlocking clips that allow multiple booms to be joined
This design ensures oil is contained on the surface and prevented from spreading.
Specifications:
Material: Hydrophobic polypropylene
Length: Commonly 3mtr sections
Diameter: 12.7cm x 3mtr  and 20cm x 3mtr
Connection: Clip‑together linking system
Colour: White (oil‑only)
Buoyancy: High‑float design for marine environments
Compliance Note:
Floating oil booms support HSWA and EPA requirements by helping workplaces contain and manage oil spills on water, preventing environmental contamination and protecting stormwater systems.
