Summary
A near miss during onshore blasting and painting involved a 2″ hose separating at an improperly tightened Chicago connector. Its restraint arrested the hose, but released energy overturned an air receiver standing unstably on sand. The flash recommends stable footings, connection inspections, restraints and assessment of safer connectors and protective barriers.
