Behaviour-based Safety Intervention in Pipeline Operation Sites in Nigeria

The study investigated the effectiveness of Behavioral Based Safety (BBS) intervention amongst
workers in pipeline construction and pipeline maintenance sites for the reduction in high injuries and
accident frequency rate experienced at their locations. Multiple Correspondence Analysis was applied
to check for similarity trend amongst pipeline workers with respect to safety management, actively
caring and safety perception. Non-Linear regression functions were used to model from the BBS
checklist, the percentage safe behaviour as related to the observed behavioral activity. Descriptive
statistics was also used to analyze the BBS checklist within the baseline observation and intervention
period. Within all groups of workers, it was shown (SP-Q7) that “Stress from factors outside work
affects their ability to work safely”. BBS process at site during baseline observation showed a baseline
percentage of "risk behaviour" and "safe behaviour" to be significantly high in PPE (33%),
Transportation (36%) and Body position (24%). It was also recorded at the third BBS intervention
period, a reduction in the percentage of "risk behaviour”, showing PPE (7%), Transportation (8%) and
Body position (6%); after training, observation, coaching and feedback on critical behaviors were
carried out. There was a remarkable improvement in the observation of Body position, Tool &
Equipment and Transportation during the intervention period. It was also shown from the developed
model the goodness of fit, R2 of 61.3% was obtained with respect to risk at work activity.
