Be sure to follow safety procedures and use personal protective equipment if necessary. Take photos or make sketches when possible. The most important part of the investigation is analyzing the facts to determine why the incident happened. This task is difficult because there is almost never a single, simple reason. Concentrate on underlying causes, usually a combination of factors.
Examples are machinery, raw materials, inadequate safeguards.
Examples might include physical changes, procedural changes, more training or a better safety program. Be sure that management, supervisors and employees follow through with the appropriate measures.
