The U.S. Environmental Protection Agency (EPA) investigated DuPont Co.'s Belle Plant at Charleston, West Virginia in late January 2010 due to a deadly phosgene hose leak. This leak killed one of the veteran workers, Danny Fish, who had worked at the plant for 32 years. The hose accidentally sprayed phosgene on him, which was widely used as poison gas during World War I, and he died the next day.
According to the Association of Hose and Accessories Distribution (NAHAD) Hose Assembly Guidelines, a hose must be used within six months after it has been fabricated. Inspection of industrial hoses must be conducted everyday to ensure safety and prevent gas and chemical leaks within the facility. This includes checking for cuts, gouges, softness, bulging spots, darkening, misalignments, and chemical-charting compatibility. For additional plant safety, hoses must be replaced after six months it has been installed.
Apparently, DuPont installed this particular hose in June 2009, when its fabrication date was May 2008. A replacement for the hose was, at the time of the accident, five months overdue. DuPont was cited by the EPA officials for violations against the federal Clean Air Act regulations. The plant failed to comply with EPA's preventive measures to control chemical leaks that are hazardous to the environment. The hose used was worn and frayed.
The hose involved in the leak was made of braided-steel, which the EPA investigators have concluded to be the wrong type of hose to be used. Phosgene is extremely hazardous in nature - it can decompose to carbon monoxide and chlorine if it was exposed to high temperature. Metals, such as the braided-steel hose, can easily ignite phosgene when they are exposed to heat or chlorine. This reaction can cause a lethal chemical reaction, which endangers anyone who inhales or is exposed to it.
To prevent industrial hazards such as this, company employers must comply with the regulations of EPA and other government agencies that promote the safety and security of humans and the environment. Industrial problems such as leaky hoses can be corrected with a simple solution. Hose repair products are excellent preventive measures that can assist companies to minimize those harmful chemicals from leaking, dripping and spilling.
Here are the different types of Hose Repair products for different hose leak use:
Bib Hose Repair - this bib is easily slid over to drippy hose ends to catch leaks before they can form a puddle of chemicals. It is commonly used for slow-dripping ends and it has an inner absorbent pad that absorbs and collects hydrocarbons. This bib hose repair eliminates possible physical and industrial hazards caused by liquid chemicals.
Hose Wrap Repair - this is used to wrap around leaky hoses, complete with hook and loop closure system, to contain potential spills. This prevents possible chemical exposure and contamination from spilling out due to its highly absorbent pad inside. This is also color coded for instant identification.
Durasorb Hose Wrap - this one has an absorbent pad which quickly absorbs leaks from hoses. It is used to wrap around larger hoses and heavier leaks. This has a tight closure system with hook and loop for more secured spill containment.
These Hose Repair products are specifically made to contain those hazardous hose leaks. They absorb those drips that may put lives in danger and damage the facility. Although toxic chemicals are difficult to control, using the proper equipment can minimize the potential dangers those harmful substances do to the environment.
