Occupational Safety and Health in Finland

In Finland, occupational safety is the responsibility of the employer, while the occupational safety and health laws are enforced by the Labour Inspection Service, an organization of the state. The Labour Inspection is divided in 11 administrative districts, and it employs 360 professionals. They are mandated to carry out site visits without prearranged appointments to inspect safe work situations, working hours, construction safety, or any aspect of accident risks. The inspectors are also mandated to verify the existence of sufficient occupational health services as prescribed by the Occupational Health Services Act for all employees. The occupational health services are typically provided by enterprise-owned medical departments, by mutually owned health care centers, by private practitioners, or by municipal health care centers. The latter are required by law to provide all services as prescribed by the legislation to anyone who comes to the facility. This situation is prevalent in the countryside, where there are very few private caregiving centers. Declaring occupational accidents and disease cases is mandatory, and the Inspection districts examine all accidents to establish causes and consequences, and to initiate prosecution in case of criminal negligence. Labour Inspection Districts are also notified of the new occupational disease cases as they are declared to insurance companies. Insurance for occupational disease, accidents, and death is an obligation of the employer, although they can choose the insurance company. The medical confidentiality between the workers and their occupational health care providers is very strict. Official statistics are maintained by the state Statistics Finland organization, and they may be used, for example, for research purposes by scientific institutes like the Finnish Institute of Occupational Health. Construction industry accounts for 25% of all fatal accidents (120 cases per 1 million working hours), followed by mechanical, wood, metal, machinery, and pulp and paper industry (10% each of fatal accidents) with rates ranging from 100–160 cases per 1 million working hours. There are some 5,000 occupational disease cases per year (rate 22/10,000 employed). The major disease categories include repetitive strain injuries (1,300 cases), respiratory allergies (600 cases), occupational skin diseases (1,000 cases), and 900 cases of noise-caused hearing loss. In 1998, 589 cases of asbestos-related diseases were reported.

GAME-THEORETIC ANALYSES OF ENFORCEMENT OF ENVIRONMENTAL LAWS AND REGULATIONS1

ABSTRACT: Game-theoretic models are developed for describing and analyzing the inspection and enforcement process, especially as it relates to environmental laws and regulations in North America. Based on these models, systems using irrevocable control orders can be compared to those relying on court determination of guilt and punishment. The cost-effectiveness of environmental enforcement can be systematically assessed in terms of factors such as the private gains for violators, the costs of inspection, penalties, and the social value of deterring violations. The policy implications of the analysis, especially with reference to environmental protection, are emphasized.

The costs and benefits of predator inspection behaviour in Thomson's gazelles

Summary When Thomson's gazelles (Gazella thomsoni) detect stalking predators, such as cheetahs (Acinonyx jubatus) and lions (Panthera leo), they often approach and follow the predator for up to 72 min (average 14 min). Coursing predators are rarely approached. Gazelle groups were more likely to approach cheetahs if the groups were larger, if the vegetation was low, or if the cheetahs came closer to the group. Immature gazelles were more likely to approach than adults, and a higher proportion of group members participated in inspection behaviour in small groups than in large ones. Gazelles approached closer in less risky situations: if they were in larger groups or if the vegetation was low. Inspection behaviour caused cheetahs to move further between rests and between hunting attempts. Approaching cheetahs was risky, particularly for younger gazelles (probability of being killed while inspecting a cheetah was 1 in 5000 approaches for adults and 1 in 417 approaches for half-grown/adolescent gazelles), and the risks were higher than monitoring cheetahs from a distance. The time costs of predator inspection were also considerable (less than 4.2% of daylight time budget), suggesting that the benefits must be substantial to offset these costs. The results suggested that inspection behaviour was multifunctional, causing stalking predators to move out of the vicinity, enabling gazelles to monitor the predators' movements, and providing an opportunity, particularly for younger animals, to learn about predators. By approaching, gazelles also inform predators that they have been detected and alert other gazelles to the predators' presence.
