According to Dupont official, the chemical storage tank was emptied and cleaned up for several times to make sure it is safe to do welding work. However, some chemical reactions took place when the welding work was in process and caused the chemical storage tank exploded.

Do You Remember the Lessons?

After reading the accident at work story that was happened during hot work, immediately I remembered the 7 Key Lessons to Prevent Worker Deaths During Hot Work In and Around Tanks issued by the US Chemical Safety Board.

Do you remember that lessons? Or may be you haven’t read it yet? No problem, because in this post I will re-write them to remind you the hazard of hot work.

Here are the 7 key lessons taken from recent hot work related accidents:

1. Avoid hot work and use alternative methods if possible. Hot work is very danger.

2. Carry out hazard assessment before starting a hot work. Define the scope of hot work, identify the potential hazards, assess the risk and determine appropriate hazard control methods.

3. Use a accurately calibrated combustible gas detector to monitor flammable atmosphere prior to and during the hot work activities.

4. Eliminate all possible flammable liquids and gases that may appear around the tank where hot work is done, as well as from the surrounding tanks, pipes and containers.

5. Employ written hot work permit that is issued by a qualified personnel who knows exactly the site specific hazards and required safety precautions.

6. Provide hot work-related training which covers hot work policies and procedures, appropriate use of combustible gas detector, gas detector calibration, safety equipments, hazard identification, risk assessment and hazard control.

7. Inform contractor workers about the presence of flammable liquids and gases, and other hot work-related hazards. Supervise their hot work activities appropriately.
