Would two construction experts see the same SIF threat on the same site? This study from Frank Benin, Sid Bhandari & Matthew Hallowell evaluated how 19 construction experts perceive the likelihood of SIFs during routine work and how confident they were in those assessments. Assessments were sought via 3 work site scenario photos (so note… Continue reading Differences in SIF Risk Perceptions among Construction Experts

Impact of Energy-Based Safety Training on Quality of Prejob Safety Meetings and Control of Hazardous Energy in Construction: Multiple Baseline Experiment
This study explored the role of energy-based safety training on the quality of the prestart meetings. Method was a multiple baseline assessment on 10 construction crews in the US and Canada following the training intervention, then measuring the prejob safety brief quality and HECA (High Energy Control Assessment). Background: · Construction accounts for about 7%… Continue reading Impact of Energy-Based Safety Training on Quality of Prejob Safety Meetings and Control of Hazardous Energy in Construction: Multiple Baseline Experiment
Moving beyond TRIR: Measuring and monitoring safety performance with high-energy control assessments
Another post on SIFs, this time the High Energy Control Assessments (HECA) from Oguz Erkal & Hallowell. Link to article below, plus to a HECA guide, and to the SIF compendium. Extracts: · HECA is “the percentage of high-energy hazards with a corresponding direct control” · HECA is binary because “every condition observation is modeled only as… Continue reading Moving beyond TRIR: Measuring and monitoring safety performance with high-energy control assessments
