INCIDENT/ ACCIDENT INVESTIGATION REPORT
Title of the Incident/ Accident
ST. Francis Dam disaster in California
Brief Summary
At 11:57PM on March 12, 1928, in the St. Francis Dam. It seemed that the huge dam collapse and so this was a catastrophic failure, it has been built to supply the city of Los Angeles with water because of the growing number of the population. The dam has been built by the Ministry of the Los Angeles Water and Power, in the period between 1924 and 1926. The department was under the direction of its General Manager and Chief Engineer William Mulholland, who designed and built the dam. As a result the collapse of the dam led to the loss of property of human lives.
Purpose of the report

Francis dam was built in 1926 with an old manufacturer’s instructions. It was constructed with normal bricks and concrete only that is non-waterproof.
The new manufacturer’s instructions have necessary rules to follow that consist of specific materials for dams and important maintenance. By following the necessary rules of the manufacturer’s, a maintained dam can be build.
1.9 Health and Safety factors
After the incident happen, the California legislature decided to make some updates and rebuild destroyed dams and it was given the authority to maintain and supervise all non federal dams which were above 25 feet high. The new legislation also allowed California to employ consultant depends on what is necessary.
1.10 Environment
The explosion of the dam led to land degradation and destruction of the land and loss of a large amount of water that cannot be easily retrieved .It led to the destruction of the town that was inhabited by local residents. As a result this collapse caused the loss of much of the property, which is estimated at 7 million dollars. Some considered that the collapse of this dam is the worst disaster in the field of American Civil Engineering.
2 Analysis and …show more content…
These regulations provide a safe environment for the workers to carry out their assigned tasks
In addition, in response to the catastrophe of St. Francis Dam, the establishment of a legislative body of California updated dam safety and the elimination of municipal exemption program. Before was add this, and was mayor their own engineering department completely exempt from regulation.
1- In the time of weather is starting change the government must till the people that are living near the dam to go outside from that place.
2- Also the dam must have another way to reduce water pressure.
3- The government must know the perfect place to state building the dam.
Conclusion
Findings as to causes:
• Technical faults
• Worker’s negligence
Findings as to underlying factors:
• Maintenance
• Training
• Supervision
• HSE Regulations
Order / recommendations issued after the investigation
• Maintenance
• Training
• Supervision
• HSE Regulations
