Process safety performance
In line with industry standards, we measure and report process safety incidents according to
significance, with Tier 1 as the most significant. The number of Tier 1 and 2 operational process
safety events decreased from 121 in 2020 to 42 in 2021, of which 60 were Tier 1 and 0 were
Tier 2. For comparison, there were 35 Tier 1 and 86 Tier 2 operational process safety events in
2020.
In 2021, the most significant incident related to process safety was an explosion and
subsequent fire at the Shell Scotford Complex in Canada. The incident was caused by a sudden
rise in temperature within a heater as we were preparing to shut down a section of the facility.
New heater protection controls were installed to help prevent this type of incident occurring
again. There were no injuries or health implications related to the incident.
Process safety events related to sabotage and theft in Nigeria are recorded separately. There
were nine Tier 1 events in 2021, the same as in 2020.
