Incident uncontrolled energy flow

The investigator documents the loss of control and subsequent uncontrolled energy transfer in the free-text description of the sequence of events. In addition, it is common for statistical purposes to classify the event by accident type . Table 6.6 shows two different schemes for classification of this energy transfer. The first is a traditional accident type classification applied by OSHA in the USA (OSHA, 1971/97). The second is taken from a proposed scheme for the classification of occupational injuries (ILO, 1998). 

It is also common to register the object or substance involved in the energy transfer, the so called injury agency . Table 6.7 shows the classification of 

Building, constructions and areas Prime movers Distribution systems Hand tools 

Machines and equipment Conveying, transport and packaging equipment 

Agents, substances, materials and objects, including radiation Living oiganisms and human beings Physical and natural phenomenon, including natural disasters Household equipment, aids for schools and instruction and personal articles
