Arkema Plant Incident Analysis

Hurricane Harvey caused catastrophic flooding in Texas, impacting the Arkema Chemical Plant. The plant's safety systems failed due to unprecedented flooding, leading to chemical fires and the evacuation of nearby residents. The incident highlighted the need for better preparation for extreme weather events and the importance of considering flood risks in safety analyses. The CSB investigation revealed gaps in flood risk assessment and provided key lessons for chemical facilities to improve safety measures.

What was the primary cause of the Arkema Plant incident during Hurricane Harvey?

• A power outage due to flooding

• A chemical reaction gone wrong

• An earthquake

• A fire in the storage area

What was the role of the ride-out crew at the Arkema Plant?

• To evacuate the plant

• To manage the plant's operations during the hurricane

• To repair damaged equipment

• To conduct safety drills

What action did Arkema management take when it became clear that the trailers would fail?

• They moved the trailers to higher ground

• They called for additional backup generators

• They decided to evacuate the remaining workers

• They increased the cooling system's capacity

Why was the highway near the Arkema Plant initially kept open during the incident?

• The evacuation zone was not enforced

• There was no visible smoke

• The highway was not affected by the flood

• It was the only route for emergency responders

What was the outcome for the six remaining trailers at the Arkema Plant?

• They were moved to higher ground

• They were subjected to a controlled burn

• They remained intact without any issues

• They caught fire unexpectedly

What did the CSB find lacking in the Arkema Plant's process hazard analysis?

• Consideration of chemical reactions

• Documentation of severe flooding risks

• Evaluation of earthquake risks

• Assessment of fire hazards

What was the main reason for the failure of safety systems at the Arkema Plant?

• Human error

• Chemical spill

• Floodwater

• Equipment malfunction

What did the CSB recommend for facilities susceptible to extreme weather?

• Install more cooling systems

• Relocate to a safer area

• Perform an analysis of potential extreme weather events

• Increase production capacity

What was a significant revision made to the flood map in 2007 regarding the Arkema facility?

• It showed the facility was at minimal flood risk

• It indicated the facility was within the flood plain

• It removed the facility from the flood map

• It showed no change in flood risk

What is a key lesson for companies with chemical facilities in flood-prone areas?

• Rely solely on insurance maps for risk assessment

• Increase chemical production

• Ensure critical safeguards are not susceptible to common failure causes

• Focus on earthquake preparedness
