DESCRIPTIVE STATISTICS OF WORK ACCIDENTS IN BRAZILIAN WOOD PRODUCT MANUFACTURING
Wood product manufacturing involves many dangerous activities and a high incidence of work-related accidents. The objective of this study was to analyze registered and unregistered work accidents, as well as the most frequent type and rate increase over the years for different activities of wood product manufacture in Brazil. Total accidents were counted including both unregistered and registered accidents. The accidents were classified as either a typical accident, a commuting accident or occupational diseases. Evaluated production was subdivided into sawmill operations, manufacture of laminated wood and plywood, wood-derived pressed and agglomerated sheets, and furniture with a predominance of wood. Wood production presented 2,849,470 direct jobs. For the furniture manufacturing sub-sector, there was an increase in the growth rate for direct jobs. However, there was a greater number of total accidents and an increase in the rate of number of accidents over time. For sawmills and the manufacture of laminated wood and slabs, there was a decreasing trend in the rate of direct jobs and accidents. Of the total number of accidents, more than 20% were not reported. The primary accident incidence was the typical accident (88.3%), followed by commuting accidents (9.5%) and lastly occupational diseases (2.1%)
WOOD-BASED MARKET IN RIO GRANDE DO NORTE BETWEEN 1999 AND 2019
The objective of this work was to analyze the firewood, charcoal and roundwood market in the state of Rio Grande do Norte (RN) in the period 1999-2019. Data provided by the Brazilian Institute of Geography and Statistics (IBGE) were used referring to the quantity produced, unit value (UV) and gross production value (GPV), subdivided according to Agreste, Central, East and West mesoregions in RN. These variables were simplified in the form of descriptive statistics, with the UV and GPV deflated with a base year of 1999. In addition, the exploration products, the total area explored, the type of cut and the situation regarding the plans of sustainable forest management - PMFS, were analyzed, as provided by the Northeastern Plant Information Center (Centro Nordestino de Informações Sobre Plantas, CNIP). The results generated allowed us note that the West mesoregion stood out in the production of firewood, being the second largest producer of charcoal and the only producer of roundwood logs. The highest UV per ton of coal occurred in 2016 in the Agreste and West mesoregions; in 2018, in the Central mesoregion and, in 2013, in the East. The highest UV per cubic meter of firewood occurred in 2017 for the Agreste and Central regions, and in 2019, in the East and West mesoregions, respectively. The Central mesoregion had the highest number of PMFS in the state, with most of the plans that are currently active being used for the exploitation of firewood. West mesoregion presented only two assets
SEGURANÇA DO TRABALHO NA PRODUÇÃO FLORESTAL
O objetivo do artigo é analisar os empregos diretos e os acidentes de trabalho ocorridos na produção florestal, em plantadas, nativas e atividades de apoio. Para cada atividade, no período de 2006 a 2014, foi contabilizado o número de empregos diretos, acidentes totais, registrados, típicos, de trajeto e doenças do trabalho e os acidentes não registrados. Foram ajustados modelos de tendência para cálculo das taxas de crescimento anual dos empregos diretos e dos acidentes de trabalho. Foi utilizada a correlação linear de Pearson para explicar a relação entre o número de empregos diretos e os acidentes da produção florestal. O número de empregos diretos gerados na produção de plantadas e nativas aumentou nos últimos 8 anos. Apenas para o setor de atividades de apoio decresceu o quadro de trabalhadores. Dentre os acidentes contabilizados, as plantadas apresentaram, em média, o maior número de acidentes, seguidos pelas atividades de apoio e produção de nativas. Muitos acidentes ocorridos não são comunicados, dando prejuízos aos acidentados quanto à reivindicação de seus direitos. Dos acidentes registrados o principal tipo corresponde ao acidente típico. Fortes correlações foram encontradas entre os empregos diretos e os acidentes totais para as florestas plantadas e atividades de apoio.Palavras-chave: empregos diretos; acidentes; cadeia produtiva. FOREST PRODUCTION WORK SAFETY ABSTRACT: The objective of this paper is to analyze the direct employment and work accidents that occurred in forest production, in plantations, native and support activities. For each activity, in the period from 2006 to 2014, the number of direct jobs, total, registered, typical, commuting and work-related accidents and unrecorded accidents were recorded. Trend models were calculated for the calculation of the annual growth rates of direct jobs and work accidents. Pearson's linear correlation was used to explain the relationship between the number of direct jobs and the accidents of forestry production. The number of direct jobs generated in plantation and native production has increased over the past 8 years. Only for the sector of support activities has the workforce declined. Among the accidents recorded, the planted had, on average, the largest number of accidents, followed by activities of support and production of natives. Many accidents occurred are not communicated, giving damage to the injured in claiming their rights. Of the accidents recorded the main type corresponds to the typical accident. Strong correlations were found between direct jobs and total accidents for planted forests and support activities.Keywords: direct jobs; accidents; productive chain
