13.1 CONTAINMENT VERSUS CONFINEMENT

Containment refers to actions taken to keep a material in its container, such as plugging or patching a leaking 55-gallon drum. Confinement refers to the procedures taken to keep a material in a defined or localized area once it has been released. Confinement is used when the chemical has breached the container and it is desirable to keep the material within defined boundaries. Confinement may be viewed as a defensive activity, and containment as an offensive activity. Through the effective use of containment and confinement, the spread of the spill or release is minimized; people, property, and the environment are protected; and cleanup and recovery operations become more efficient.

13.1.1 Major Factors for Consideration

Two major points should be considered when developing containment/confinement strategies. Safety of response personnel is the primary consideration for any response action. While responders are taught to enter from an upwind, uphill, upstream position to deal with emergency situations, they may have to respond downwind, downhill, and downstream to contain/ confine a spill. Responders may be required to work in, or at least in close proximity to the material that is spilling or being released. Proper monitoring...

Products & Services
Spill Containment Systems
Spill containment systems are used to capture and contain unintentional spills of liquid media. They are also called secondary containment systems.
Remediation Services
Remediation services include oil or chemical spill clean up, restoration of contaminated sites, and hazardous waste management.
Evaporative Coolers
Evaporative coolers are cooling devices that use the evaporation of water into the air to cool the air temperature. They are sometimes called air coolers, desert coolers or swamp coolers.
Absorbents and Adsorbents
Absorbents and adsorbents are minerals or chemicals that can capture liquids or gases.
Hazmat Storage Buildings
Hazardous material storage containers are designed to hold, store, and/or transport hazardous materials.
