Dealing with windblown trees is hazardous without appropriate training, equipment and work preparation!
There are many complex hazards in storm-affected forests with thrown, uprooted, broken, heavily leaning and hung-up trees or parts of trees:
- Impassable and obstructed roads and routes, reduced accessibility and visibility
- Incalculable tension and forces both in individual trees as well as in jammed stems and root plates
- Unstable trees, parts of trees, root plates and stones that can suddenly topple, tip over, fall or roll away without any visible reason even days, weeks or months after a storm.
The brochure "Dealing with windblown trees" is intended for people who have to deal with windblown trees. The aim of the Swiss National Accident Insurance Fund (Suva) is to:
- Make you aware of the particular dangers involved in dealing with windblown trees
- Encourage you to think about your own capabilities and limitations
- Inform you about safety rules and measures
The authors have intentionally dispensed with descriptions of working and cutting techniques. These are best learnt in practical courses. Every windblown-tree situation is different and requires an individual approach. Only when taught by a qualified instructor will you learn how to assess a specific situation correctly and how to apply the safest working and cutting techniques.
This brochure is no substitute for minimum basic training nor can it be considered to be a comprehensive training document. It is no substitute for practical, on-the-job training.
The brochure contains the following chapters:
- Dealing with windblown trees: A job involving particular hazards!
- Is your "life insurance" TOP?
