RESUMEN

The aim of this study is to analyze the subjective perception of risks for rural workers in Abruzzo, an area of central Italy. A group of 273 workers were asked to fill in a questionnaire which included, apart from general information, questions relative to six different types of risks normally found in the field of agriculture. The types of risks considered were: falling from a height, manually moving loads, overturning/accident whilst driving an agricultural tractor, noise and vibration, use of pesticides, the risk of being cut/injured. The workers were requested to assess, on a scale of 1 to 3, both the probability of an accident taking place and the consequent damage which could result from each of the risks considered. The assessment of the risks provided by the workers was related to the objective assessment of the risks carried out by the study group, also on the basis of objective data provided by INAIL (Italian insurance company) indexes, to highlight the eventual under/over estimations of risk. Furthermore, the possible correlation was evaluated between having received specific training regarding work safety and the workers perception of the risk. The results showed that approximately 11 percent of the workers do not consider their job as being dangerous; the risk perceived by the workers is higher for accidents that cause an immediate injury compared to those which cause professional illnesses, except the risk deriving from noise/vibrations. A direct correlation was found between the job as being dangerous and having attended courses on accident prevention.

RESUMEN

After the earthquake of L'Aquila, INAIL further stimulated the local Universities to train specialists in the prevention of occupational risks on construction sites. Since 2005 the University of Chieti-Pescara evaluated occupational stress (through the Karasek's JCQ) as well as perception of occupational risk of the building workers. Moreover, procedures (including planning) in the field of building technology were analyzed. The perception of job strain of the workers in building activities were high because of elevated job demand and low decision latitude. The risk perception was higher regarding dangers producing immediate injury. There was no direct relationship between considering the job dangerous and having attended training courses, while the relationship between risk perception and past injury events was marked. At present, we are also evaluating, by instrumental methods, the biomechanical overload of workers, due to the main repetitive and forceful manual activities.

RESUMEN

Efficient warehouse management and item transportation is of fundamental importance in the commercial outlet in exam. Whole body vibrations have been measured in various types of machines, some of which not widely studied yet, like the electrical pallet truck. In some tasks (fork lifts drivers) vibrations propagate through the driving seat whereas in some other tasks (electrical pallet trucks, stackers), operated in a standing posture, vibrations propagate through the lower limbs. Results have been provided for a homogeneous job tasks. In particular conditions, the action level of the Italian national (and European) regulations on occupational exposure to WBV may be exceeded. The authors propose a simple system of probabilistic classification of the risk of exposure to whole body vibrations, based on the respective areas of the distribution which lay within the three risk classes.

RESUMEN

In 2006, in the context of the initiative aimed at "Promotion of safety and health of workers in construction yards", the Operative Unit of Occupational Health, University G. d'Annunzio, in collaboration with the Construction School of the Province of Pescara and INAIL, started a survey of construction yards around Pescara aimed at collecting data regarding respect of the specific law concerning construction yards and the risk perception of workers. The survey of 100 construction yards provided useful information towards a concise picture of safety levels obtained. In addition 300 interviews were carried out with workers to find out about their knowledge of accident prevention, how important they considered the use of personal protection devices, how often they used them, reasons for not using them, the devices most used,....and any injuries that occurred. The studied showed that, although the situation as improved compared to the past, further steps need to be taken.

RESUMEN

Accidents in building sites led us to study risk perception in workers employed in this field. We disposed of 300 workers, aged 18-65, who had to answer to a questionnaries were signing among seven risks the more present in their activity, chosing among five levels. So for each risk the worker had to quantify parameters such as: danger, frequence of accidents, actitude to risk-control, training on risk. The risk of falling from high sites has been perceived as extremely dangerous but it is possible to control it. Less dangerous is eyes exposition to chemical agents or dust. Manual movementation of weight and lacerations would be the most frequent source of accidents. Moreover would be insufficient the capacity to control the rick related to Weight manual movementation and vibrations. Workers answered in questionnaries that risk training on vibration was not sufficient, on the contrary they knew the risk of falling from high site. So we conclude that to reduce accidents in building sites it is necessary make better training on field, modifying the individual behavior among workers.

RESUMEN

The disposition of intravenous and intraperitoneal administered cefoxitin was evaluated in four males undergoing intermittent peritoneal dialysis. Each patient received 1 g of cefoxitin intravenously prior to an eight-hour dialysis; subsequently, one patient received another 1 g intravenous dose prior to an 18-hour dialysis while each of the other three patients had 100 mg of cefoxitin added to their eight hourly exchanges of dialysis fluid with 2 L per exchange. Serial blood, dialysate, and urine samples were collected and analyzed for cefoxitin by a microbiologic assay. Twenty-four hours after intravenous administration, serum cefoxitin concentrations were greater than 16 micrograms/mL (therapeutic breakpoint) in each patient. Mean cefoxitin dialysate concentrations averaged 7.8 +/- 3.8 micrograms/mL and were greater than 16 micrograms/mL in only 2 of 43 exchanges. After intraperitoneal administration, serum cefoxitin concentrations were highest after the eighth exchange (range 5.6 to 10.6 micrograms/mL). Thus, diffusion of cefoxitin across the placental membrane was not extensive. Dialysis removed only 10% to 20% of the intravenous dose.
