Best practices in incident investigation in the chemical process industries with examples from the industry sector and specifically from Nova Chemicals.

This paper will summarize best practices in incident investigation in the chemical process industries and will provide examples from both the industry sector and specifically from NOVA Chemicals. As a sponsor of the Center for Chemical Process Safety (CCPS), an industry technology alliance of the American Institute of Chemical Engineers, NOVA Chemicals participates in a number of working groups to help develop best practices and tools for the chemical process and associated industries in order to advance chemical process safety. A recent project was to develop an update on guidelines for investigating chemical process incidents. A successful incident investigation management system must ensure that all incidents and near misses are reported, that root causes are identified, that recommendations from incident investigations identify appropriate preventive measures, and that these recommendations are resolved in a timely manner. The key elements of an effective management system for incident investigation will be described. Accepted definitions of such terms as near miss, incident, and root cause will be reviewed. An explanation of the types of incident classification systems in use, along with expected levels of follow-up, will be provided. There are several incident investigation methodologies in use today by members of the CCPS; most of these methodologies incorporate the use of several tools. These tools include: timelines, sequence diagrams, causal factor identification, brainstorming, checklists, pre-defined trees, and team-defined logic trees. Developing appropriate recommendations and then ensuring their resolution is the key to prevention of similar events from recurring, along with the sharing of lessons learned from incidents. There are several sources of information on previous incidents and lessons learned available to companies. In addition, many companies in the chemical process industries use their own internal databases to track recommendations from incidents and to share learnings internally.

Relationships between academic institutions and industry in the life sciences--an industry survey.

BACKGROUND: Despite growing acceptance of relationships between academia and industry in the life sciences, systematic, up-to-date information about their extent and the consequences for the parties involved remains scarce. We attempted to collect information about the prevalence, magnitude, commercial benefits, and potential risks of such relationships by surveying a representative sample of life-science companies in the United States to determine their relationships with academic institutions. METHODS: We collected data by telephone from May through September 1994 from senior executives of 210 life-science companies (of 306 companies surveyed; response rate, 69 percent). The sample contained all Fortune 500 companies in the fields of agriculture, chemicals, and pharmaceuticals; all international pharmaceutical companies with sales volumes similar to those of the Fortune 500 companies; and a random sample of non-Fortune 500 companies in the life sciences drawn from multiple commercial and noncommercial directories. Both the survey instrument and the survey methods resembled those of our 1984 study of 106 biotechnology companies, allowing us to assess the evolution of relationships between academia and industry over the past decade. RESULTS: Ninety percent of companies conducting life-science research in the United States had relationships involving the life sciences with an academic institution in 1994. Fifty-nine percent supported research in such institutions, providing an estimated $1.5 billion, or approximately 11.7 percent of all research-and-development funding received that year. The agreements with universities tended to be short-term and to involve small amounts, implying that most such relationships supported applied research or development. Over 60 percent of companies providing support for life-science research in universities had received patents, products, and sales as a result of those relationships. At the same time, the companies reported that their relationships with universities often included agreements to keep the results of research secret beyond the time needed to file a patent. From 1984 to 1994, the involvement of industry with academic institutions has increased, but the characteristics of the relationships have remained remarkably stable. CONCLUSIONS: After more than a decade of sustained interaction, universities and industries seem to have formed durable partnerships in the life sciences, although the relationships may pose greater threats to the openness of scientific communication than universities generally acknowledge. However, industrial support for university research is much smaller in amount than federal support, and companies are unlikely to be able to compensate for sizable federal cutbacks.

Tobacco industry litigation to deter local public health ordinances: the industry usually loses in court.

BACKGROUND: The tobacco industry uses claims of state preemption or violations of the US Constitution in litigation to overturn local tobacco control ordinances. METHODS: Collection of lawsuits filed or threatened against local governments in the USA; review of previously secret tobacco industry documents; interviews with key informants. RESULTS: The industry is most likely to prevail when a court holds that there is explicit preemption language by the state legislature to exclusively regulate tobacco. The industry has a much weaker record on claims of implied preemption and has lost all challenges brought under equal protection claims in the cases we located. Although the tobacco industry is willing to spend substantial amounts of money on these lawsuits, it never won on constitutional equal protection grounds and lost or dropped 60% (16/27) of the cases it brought claiming implied state preemption. CONCLUSIONS: Municipalities should continue to pass ordinances and be prepared to defend them against claims of implied preemption or on constitutional grounds. If the ordinance is properly prepared they will likely prevail. Health advocates should be prepared to assist in this process.

[Preparedness of health personnel in a highly industrialized health area of Asturias to respond to industrial disasters].

BACKGROUND: In order to provide a response to industrial accidents with a view to minimizing their consequences, the healthcare personnel working in areas at risk must be properly trained. This study is aimed at determining the degree of subjective perception that healthcare professional have with regard to how well-prepared they are to take action in response to an industrial accident resulting in a large number of injuries, as well as their knowledge of industrial hazards inherent to the area. METHODS: A questionnaire was designed to measure five dimensions related to the response to industrial accidents (technical knowledge, knowledge of the Area, practical skills, attitudes and training). The sample was comprised of all of the Primary Care physicians and nursing staff in the District and from the Emergency Department at the related hospital. RESULTS: The response rate was 61.2%. The results for the questions related to each dimension, on a maximum scale of 4, were: Technical skills (mu = 1.3; delta = 0.81); Knowledge of the District (mu = 0.75; delta = 0.96); Practical skills (mu = 0.9; delta = 0.8); Attitudes (mu = 3.25; delta = 0.73) and Training (mu = 0.75; delta = 0.88). Those working in hospital emergency departments and those hired under indefinite or temporary contracts scored higher than those employed under permanent contracts. CONCLUSIONS: Information and training is lacking among these healthcare professionals, contrasting with the interest shown in correcting these lacks. It is necessary for a basic training and information program to be set up in order to deal with industrial disasters in our Healthcare District.

School screening in the heavily industrialized area--Is there any role of industrial environmental factors in idiopathic scoliosis prevalence?

INTRODUCTION: School-screening programs contributed greatly to the study of idiopathic scoliosis (IS) prevalence. A similar program confined to a highly industrialized area is being performed in our Department. Thus the comparison of the findings of IS prevalence of this program with those of programs performed in non-industrialized areas of the same country could imply the significance of special industrial environmental factors on IS aetiology. MATERIALS AND METHODS: 3039 schoolchildren (1506 boys, 1533 girls), aged 5,5 to 17,5 years, have been screened for IS. These children comprise 20% of a total population of 20000 schoolchildren, who live in the region. The detection of the scoliotic children was attained utilizing the criterion of the angle of trunk inclination (ATI). The Prujis scoliometer was used to assess ATI. A cut off point of > or = 7 degrees ATI was used as a criterion for children's referral to hospital. 262 (8,6%) were referred for further evaluation, whereas 118 (3,9%) among these children underwent radiological examination. RESULTS: 90 children were found to have a Cobb angle of > or = 10 degrees at their standing PA spinal radiographs (2,9 % of the screened population). A Cobb angle of 10 degrees -20 degrees was found in 74 (2,4%) children. Sixteen (0,5%) children, who had scoliotic curves with a Cobb angle of > or = 20 degrees, underwent conservative treatment by means of spinal orthosis. Relatively to their location on the vertebral column, 20% of the scoliotic curves were thoracic, 26,7% thoracolumbar, 20% lumbar, 24,4% double and 8,9% miscellaneous. DISCUSSION: The screened area represents a place of particular interest because it experienced considerable environmental pollution during the past decades without any improvement of the available Health Services. A quite diverse population in relation to its occupation and its origin inhabits this area as well. The scoliosis incidence found in this area is similar to the incidence observed (2,9%) at other non-industrialized geographical departments of this country (2,6%). This implies that industrial environmental factors probably do not significantly influence the prevalence of AIS.

[Industrial noise and presbyacusia in the determination of hearing damage: studies in chemical industry workers].

An audiometric investigation was carried out on 710 workers of a chemical plant in order to ascertain the role of industrial noise and presbysocio-acusia in causing hearing loss. The workers underwent an audiometric test both aerial and via bone, in a sound-proof chamber, after a 16-hour rest from noise. The subjects also answered a questionnaire on nonoccupational noise exposure and previous hearing and dysmetabolic disorders. Noise exposure was assessed on the basis of a cumulative exposure index obtained for each subject by multiplying the mean daily exposure level by seniority in the job. The results showed that in workers not exposed to high noise levels, industrial noise and presbysocio-acusia induce, via a direct mechanism, either separately or together, only slight damage to social hearing frequencies, i.e., those of normal conversation. At frequencies of 4 and 6 kHz, however, presbysocio-acusia seems to play a more important role than industrial noise in causing hearing loss. The practical implications arising from this study concern the frequencies that should be used for a medicolegal assessment of industrial noise induced hearing loss and the the threshold for these frequencies above which assessment of hearing loss should begin. As regards the first point, the results obtained in this study suggest the use of medicolegal methods based on normal conversation frequencies since presbysocio-acusia should not in any case be taken from these frequencies as it affects them only marginally. As regards the second point, the results show that assessment of hearing loss should begin when the hearing threshold at the above frequencies exceeds 25 dB. The study also showed that in epidemiological investigations on subjects exposed to industrial noise, the cumulative exposure index is better correlated with the rise in hearing threshold at the various frequencies than with seniority.

[Analyses of industrial society from ecology--modeling analyses of industrial ecological system].

A macroscopic industrial ecological model has been developed to investigate the effects of changes in industrial structure on social well-being in general and health in particular. The model is composed of the following sectors: industry and employment, environment and pollution, and population and health care. The model was calibrated using available data of the past 60 years for Japan. The simulation study was conducted with the time span of 1920 to 2000. The results indicated that the gradual shift, in the industrial structure of Japan, would improve the level of living standards resulting in enhanced health service capability and lower death rate although increasing adult disease rates in the aged society. Also the rapid future growths of service industry and information and communication were observed.

Mortality and industrial employment. III. Industries with high standard mortality ratios for persons with social security coverage in 1960 and 1965.

Data are available on a 1% sample of social security covered employees by industry, age, sex and race for years 1960 and 1965 and their mortality through 1972. Previous papers have reported on overall rates by age, sex and race and on industries in which mortality appears to be increased among younger workers. In this paper mortality ratios, compared to the expected overall race-sex-age specific rates for this population, are shown for the Standard Industrial Classification two-digit-industry classes for the 1960 and the 1965 cohorts. Among women employed in four industries involving chemical exposures, an abrupt increase in mortality occurred around 1965. Possible reasons for this are discussed. The epidemiologic usefulness of social security mortality data for occupational and preventive purposes and for surveillance is emphasized.

Low mortality rates in industrial cohort studies due to selection for work and survival in the industry.

Occupational groups are often described as being relatively healthy because their mortality rates are lower than those of the national average. Although correct this confuses the issue for those who are interested in assessing the effects of exposure to a particular chemical. In a further analysis of data collected in a study of all men ever exposed to vinyl chloride monomer in the manufacture of polyvinyl chloride in Great Britain, three factors have been shown to contribute to the low mortality rates that were observed. The three factors: the selection of a healthy population for employment, the survival in the industry of the healthier men, and the length of time that this population has been pursued, have been quantified. The mortality experience within five years of entering this industry was shown to be as low as 37% of that expected; for circulatory disease and respiratory disease it was as low as 21%. There was a progressive increase in standardized mortality ratio with the length of time since entry so that the effect had almost disappeared 15 years after entry. To avoid confounding the selection effect with the survival effect the latter was measured by separating men who survived 15 years after entering the industry according to whether or not they were still in the industry after this period. Those who had left experienced an overall standardized mortality ratio some 50% higher than those still in the industry. This effect, although consistent in the age groups between 25 and 74 years and for all cause groups studied, was greatest in those aged between 25 and 44 years and for lung cancer and respiratory disease.
