Important Notes Taken From DuPont Gas Leak

methyl chloride leakDuPont recently reported the causes of methyl chloride leak from the phosgene unit in last January at its West Virginia chemical plant, which caused one worker died. Phosgene is a hazardous chemical used for manufacturing of pesticide and plastic that can damage the respiratory system.

According to DuPont report that was published in, the causes of the gas leak were aging hoses, corrosion and pressure build up in the line. Combination of these factors had caused hoses failed to function properly.

If we look at the causes of the DuPont gas leak, they are very common problems encountered in chemical plant operation. And they should be readily identified when we perform hazard identification work consistently.

These problems can also be identified through regular plant safety inspection. Afterward we can replace the hoses immediately after being identified, before they turn into plant accident.

As I have mentioned several times in this blog that hazard identification has to be updated regularly in order to detect potential hazards as early as possible. The easiest way to do this is through safety inspection which can be done at the same time with data reading.

Today we have learned how important it is to take action quickly and updating hazard identification consistently. Then, always bear in mind this safety slogan “Learn safety from others; don’t let people learn from us”.
