The security provided by forests is approached through various authors’ descriptions and through psychotherapeutic experience. The lap of the forest can recreate early security, protection and unity, for example the lap of mother or father. The forest is also a safe place to externalize inner feelings, desires, fears and erotic images. Intensive forest management and air pollution are nowadays threatening the protective role of forests.
The paper is based on a lecture given in the seminar ‘The forest as a Finnish cultural entity’, held in Helsinki in 1986. The PDF includes a summary in English.
The safety clothing, rubber safety boots, belt with lifting hooks and personal protectors can weight about 3 kg more than the normal work clothing including rubber boots. In order to evaluate the increase off the physical strain in logging work due to them, laboratory tests performed on tread mill were made. The physical strain increased 3–11% as estimated from heart rate and 4–8% as estimated from oxygen consumption measurements.

Silva Fennica Issue 64 includes presentations held in 1947 in the third professional development courses, arranged for foresters working in the public administration. The presentations focus on practical issues in forest management and administration, especially in regional level. The education was arranged by Forest Service. Two of the presentations were published in other publications than Silva Fennica.
This presentation describes application of labour legislation and occupational safety act in forest work.
Labour legislation has developed strongly in a short time, and ways of its application have not yet been established. The article defines first the concept of forest worker from the point of view of the labour law. Collective agreement, contract of employment, wages, work instructions, and labour disputes concerning forest work are discussed. Finally, the author discourses the issues associated to occupational safety and health legislation, for instance, working hours, accident insurance and forest accommodation.
Forest work is typically seasonal, and it is payed for time or piece rates or by the job. The collective agreements have been difficult to apply in forest work, and more important have been the contract of employment. Labour disputes have been rare. The reported accidents in forest and floating work have increased since the Law on Accident Insurance entered into force in 1925. Compared to many other sectors, forest work has high risk for accidents.

Industrial chipping is becoming increasingly popular, as the result of a growing demand for woody biomass. Industrial chippers are large, powerful machines that generate much noise and vibration. This study explored some factors that may affect exposure to noise and vibration, namely: feedstock type (branches vs. logs), work station characteristics (truck cab vs. separate cab) and knife wear (new knives vs. blunt knives). Exposure to noise was significantly affected by all three factors, and it was higher for branch feedstock, separate cabs and blunt knives. The higher exposure levels recorded for the separate cab were especially insidious, because they were below and above the hearing threshold and would elude immediate perception. Exposure to whole-body vibration (WBV) was significantly higher for branch feedstock and for the separate cab. Knife wear seemed to determine an increase in WBV, but this effect had no statistical significance and the result could not be taken as conclusive. Among the three factors studied, work station characteristics had the strongest effect. Further studies may extend the comparison to a wider range of options, as well as explore the use of exposure variation for machine diagnostics.
