Résumé

The present study is conducted to prove or disprove the presence of an accident-prone person and to define the possible contributing factors. 26 workers, in 3 large-scale plants, were found to have experienced two or more accidents in the last 2 years. Those workers, in addition to 26 control subjects were subjected to a questionnaire inquiring about the personal, socioeconomic and vocational data. They were also subjected to Eysench Personality Questionnaire [EPQ] measuring 3 basic personality traits, extroversion/introversion, psychocitism, sociability and neurocitism/emotional stability. Memory was also evaluated by digit span, psychomotor ability by H-mark ad dotting tests, verbal and structural intelligence by similarity tests adopted by the National Institute of Industrial Psychology [NIIP] and perception by tool matching test. Significant differences were found between the accident-prone and the control subjects, concerning medical disorders, personality traits, intelligence, perception and psychomotor speed, but not memory span

Résumé

Soldering is a principal operation in electronics andrelated industries. Lead tin alloy is used as a soft solder. In such processes, a flux is added to this alloy to clean and dry the solded surface. The flux used in this operation is fluorspar [calcium fluoride]. Solderers were exposed to the fumes of lead, tin as well as fluorine gas and oxygen fluorides. The results showed that solderers [n=67] were symptomatizing fromneurological [43.3%], musculoskeletal [32.8%] and gastro intestinal [13.4%] manifestations consistent with chronic lead poisoning. Respiratory symptoms in the form of tightness of the chest on exposure [19.4%] and chronic bronchitis [6%] could be due to inhalation of oxides of fluorine as well as isocyanates liberated from heating fluorspar an polyurethane coating of solded wires, respectively. The eye and nose irritation might be also caused by such irritant gases. Skin manifestations in the form of falling hair, alopecia areata and pruritus could be due to exposure of the skin to these irritant gases as well as possible psychic stress. Pallorand hypertension [16.4%and13.4%, respectively] as well as neurological signs [10.4%] are mostly related to lead poisoning. Cases with chest tightness showed 10-21.4% reduction in FEV1 value from the basic level confirming the diagnosis of occupational asthma in those cases
