"As designers of chemical plants that can be potentially harmful and that often handle dangerous materials, we feel the responsibility to build ever safe systems that can create new jobs and at same time never in any case cause any harm to people and the environment. One of the most important step is to learn from the past and keep the memory of the mistakes made".
We present here a very interesting collection of videos from Chemical Safety Board.
CSB conducts root cause investigations of chemical accidents at fixed industrial facilities. Root causes are usually deficiencies in safety management systems, but can be any factor that would have prevented the accident if that factor had not occurred. Other accident causes often involve equipment failures, human errors, unforeseen chemical reactions or other hazards. The agency does not issue fines or citations, but does make recommendations to plants, regulatory agencies such as the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA), industry organizations, and labor groups. Congress designed the CSB to be non-regulatory and independent of other agencies so that its investigations might, where appropriate, review the effectiveness of regulations and regulatory enforcement.
UNCONTROLLED CHEMICAL REACTIONS
Many industrial chemical processes involve exothermic (heat generating) reactions. Uncontrolled or runaway reactions can occur as a result of various situations, such as mischarged raw materials, failure of a reactor's cooling system, control systems, or the presence of contaminants. If the heat generation exceeds the reactor's ability to remove it, the reaction can accelerate - or run away - and cause the temperature and pressure to increase. A sudden energy release from such an uncontrolled reaction has the potential to harm workers, the public, and the environment. This video shows 4 good examples.
2015 EXPLOSION AT EXXON MOBIL REFINERY
2010 - EXPLOSION AT TESORO'S ANACORTES REFINERY
An explosion and fire led to the fatal injury of seven employees when a nearly forty-year-old heat exchanger catastrophically failed on April 2, 2010. This wonderful video depicts the events leading up to the accident.
2010 - PHOSGENE ACCIDENT
DuPont facility in Belle, West Virginia
2008 - BAYER CROPSCIENCE PESTICIDE WASTE TANK EXPLOSION
This video depicts the events leading up to the accident occured in Kanawa Valley, Charleston West Virginia.
2007 - EXPLOSION AT T2 LABORATORIES
On December 19, 2007, a runaway chemical reaction during the production of a gasoline additive destroyed T2 Laboratories in Jacksonville, Florida, killing four people and injuring 32 others. The blast, equivalent to about 1400 pounds of TNT, damaged buildings and injured office workers hundreds of feet away. This wonderful video depicts the events leading up to the accident.
2005 - BP TEXAS CITY EXPLOSION
On March 23 , 2005, several explosions and a fire occurred during the start-up of the isomerization unit at the BP Texas City refinery. Fifteen workers were killed and 170 Others were injured when highly flammable gasoline components were released from a raffinate splitter tower.
This wonderful video depicts the events leading up to the accident.
