This study investigates the risk of head injuries, specifically concussions, from falling objects in workplace accidents. A case study focuses on a construction worker who sustained a head injury despite wearing a protective helmet. Utilizing finite element (FE) analysis, the helmet-head system was modeled to assess impact forces and head accelerations. The helmet, made of High-Density Polyethylene with a 6-point suspension system, was tested against falling objects of 332 g and 665 g. Simulations, conducted from heights of 5 to 25 m, revealed that objects weighing as little as 332 g could cause severe concussions from a 10-meter fall. These findings demonstrate that helmets, while mitigating some impact, absorb significantly less energy than the kinetic energy of falling objects. The analyses carried out confirmed the worker's statement that his injury was caused by a foreign object falling on his head, which was protected by a helmet.

Power hammers are mechanised forging devices that constitute a pivotal part of steel manufacturing. Power hammer-associated injuries are a rare occurrence. We report a noteworthy case of a 52-year-old man who sustained a high-energy penetrating injury while working with a power (counterblow) hammer. The man used a sizable disc-shaped metallic object to dislodge the forging wedged in the machine by applying the force of the striking ram on it. On impact, the object ejected and struck the man in the right lateral portion of the chest. The autopsy disclosed extensive damage to the thoracic and abdominal organs. The cause of death was opined to be exsanguination due to penetrating trauma of the heart and transection of the descending aorta. The investigation confirmed a breach of safety regulations. To the best of our knowledge, this is the first power (counterblow) hammer-related fatality in medico-legal literature.

INTRODUCTION: Forestry provides a wide range of employment opportunities worldwide and is seen as one of the high-risk industries in terms of occupational accidents. OBJECTIVES: The submitted study analyzed the injury rate in the Military Forests and Estates of the Slovak Republic (62.6 thousand ha) between 2013 and 2022. METHODS: The data analyses included regression and correlation analyses, χ2 tests to analyze the relationships between studied variables, and incidence rates. RESULTS: During the observed period, employees suffered 26 occupational accidents, of which 19.2% were light, 57.7% were registered, 23.1% were severe, and 0% were fatal. For every 1 million m3 of harvested timber, 7.7 accidents occurred. The incidence rate during the observed period was 672.1/100,000 employees. The highest proportion of accidents was in the age group 51-60 years and in employees with the lowest length of work experience <5 years. Regarding time, the highest proportion of occupational accidents occurred between 8:01 and 10:00 AM (53.8%) and day-wise on Thursdays (46.2%). The highest proportion of accidents occurred among forest workers (65.3%) during pruning and silviculture activities (42.3%). The most common injury site was forest stands (65.3%). Superficial injuries (34.6%) were the most common, mainly affecting the lower limbs (50%). The most frequent material agents causing the accidents were work and transport areas as sources of worker fall (38.5%), and the most frequent reason for an accident to occur was the lack of personal requirements for proper work performance (92.4%), whereas only (3.8%) of accidents occurred due to the use of forbidden or hazardous working procedures. CONCLUSION: The presented study identified the most vulnerable worker groups and provided an overview of the overall injury rate at the state forest company in Slovakia. The documentation can be incorporated into the safety strategies of forest enterprises.
