Leak containment

Small leak containable with absorbents easily. 

In order to protect air resources, TSDFs are required to install unit controls to prevent organic emissions from escaping into the air. The air emission controls apply to process vents, equipment leaks, containers, surface impoundments, and tanks. 

Spill/Leak Disposal If leaks or spills of Sarin occur, only personnel in full protective clothing will remain in the area. Spills must be contained by covering with vermiculite, diatomaceous earth, clay, fine sand, sponges, and paper or cloth towels. Decontaminate with copious amounts of aqueous sodium hydroxide solution (a minimum of 10 wt.%). Scoop up all material and place it in a DOT approved container. Cover the contents with decontamination solution as above. After sealing, the exterior will be decontaminated and labeled according to EPA and DOT regulations. All leaking containers will be over packed with sorbent (e.g., vermiculite) placed between the interior and exterior containers. 

Disposal Drum A specially constructed drum used to overpack damaged or leaking containers of hazardous materials for shipment. 

After sealing the head, the exterior of the drum shall be decontaminated and then labeled IAW EPA and DOT regulations. All leaking containers shall be overpacked with vermiculite placed between the interior and exterior containers. Decontaminate and label IAW EPA and DOT regulations. Dispose of the material IAW waste disposal methods provided below. Dispose of material used to decontaminate exterior of drum IAW Federal, state and local regulations. Conduct general area monitoring with an approved monitor (see Section VIII) to confirm that the atmospheric concentrations do not exceed the airborne exposure limit (see Sections II and VIII). 

Bromomethane is usually stored in sealed containers to keep it from evaporating. If leaking containers of bromomethane are put in a waste site, most of the bromomethane will probably escape into the air. Small amounts might leak into the soil or pass through the soil and dissolve in underground water. Bromomethane has been found in underground water at two hazardous waste sites on the NPL. 

Hazardous chemical/oil spill or leak. Contain the flow as quickly as possible and as soon as possible clean up the waste and any soil or other materials that may have become contaminated with waste ...

At about 0 40 p.m. on July 10, 1976, at a chemical plant in northern Italy, a safety plate of a reactor fractured, blowing the leaking substance into the sky as a white cloud. The cloud was carried on the wind toward the town of Seveso and was conveyed to the ground there by falling rain. The substance leaked contained the highly toxic material... 

Place the entire damaged container and its contents into a suitable larger container. Consider this option carefully, however. Many times the label on the leaking container becomes illegible. The pesticide is nseless and becomes a disposal problem unless yon know the name and registration number and can get a copy of the label. 

An increasing amount of contamination results from landfills, leaking containers, and accidental spills. Many of the contaminants are volatile and amenable to aeration. A twofold approach can be used either clean the water supply or clean the contamination source. When a highly concentrated contaminant is aerated through a packed tower, then air pollution from the aeration process becomes a concern. Air discharge from the packed tower must be collected and treated. 

Agent detected inside an On-Site Container (ONC). The ONC is used to safety transport munitions from the storage area to demil facility. ONC moved to the UPA and processed. Leak contained in engineering controls. 

If possible, turn leaking containers so that gas escapes rather than liquid.
