Genotoxic exposures of potroom workers. (1/621)

OBJECTIVES: Potroom workers in aluminum reduction plants have increased risks for bladder and lung cancer due to exposure from polycyclic aromatic hydrocarbons (PAH). In this study correlations between measures of the external, internal, and biological effective dose have been studied for PAH. METHODS: Venous blood samples were obtained from 98 male potroom workers and 55 unexposed male blue-collar workers, for the analysis of aromatic adducts to DNA (deoxyribonucleic acid) in lymphocytes, using the 32P-postlabeling technique. 1-Hydroxypyrene in urine was analyzed with high-pressure liquid chromatography. Personal sampling of both particulate and gas phase PAH was performed during a full workday for the potroom workers and for 5 referents. Individual PAH congeners were determined with liquid chromatographic-mass spectrometric and gas chromatographic-mass spectrometric techniques. RESULTS: The respiratory-zone airborne level of the sum of 22 particulate (median 13.2 micro/m3) and the 7 gas phase PAH-congeners (median 16.3 microg/m3) among the potroom workers was a hundred times higher than among the referents. The urinary concentration of 1-hydroxypyrene before work was 30 times higher for the potroom workers (median 3.43 micromol/mol creatinine) than for the referents. Most airborne PAH congeners correlated with the excretion of 1-hydroxypyrene in urine. The frequency of aromatic DNA adducts did not, however, differ between the potroom workers and the referents, and no correlation was found for 1-hydroxypyrene in urine. CONCLUSIONS: Despite an obvious occupational exposure to PAH, no increase in aromatic DNA adducts in lymphocytes was found among the potroom workers.  (+info)

Effects of experimental exposure to triethylamine on vision and the eye. (2/621)

OBJECTIVES: To determine the effect of triethylamine (TEA) on the cornea and to evaluate the cause of blurred vision. To find the lowest observed effect concentration of exposure to TEA. METHODS: Four people were exposed to TEA for 4 hours at concentrations of 40.6, 6.5, and 3.0 mg/m3. Before and after every exposure, symptoms and ocular microscopy findings were recorded. Binocular visual acuity and contrast sensitivity at 2.5% contrast were also measured. Also, before and after the 40.6 mg/m3 exposure, corneal thickness was measured and ocular dimensions were recorded by ultrasonography, endothelial cells of the cornea were analysed, and serum and lacrimal specimens were collected for the analysis of TEA. RESULTS: After exposure to 40.6 mg/m3 TEA there was a marked oedema in the corneal epithelium and subepithelial microcysts. However, corneal thickness increased only minimally because of the epithelial oedema. The lacrimal concentrations of TEA were, on average (range) 41 (18-83) times higher than the serum TEA concentrations. The vision was blurred in all subjects and visual acuity and contrast sensitivity had decreased in three of the four subjects. After exposure to TEA at 6.5 mg/m3 two subjects experienced symptoms, and contrast sensitivity had decreased in three of the four subjects. There were no symptoms or decreases in contrast sensitivity after exposure to a TEA concentration of 3.0 mg/m3. CONCLUSIONS: TEA caused a marked oedema and microcysts in corneal epithelium but only minor increases in corneal thickness. The effects may be mediated by the lacrimal fluid owing to its high TEA concentration. Four hour exposure to a TEA concentration of 3.0 mg/m3 seemed to cause no effects, whereas exposure to 6.5 mg/m3 for the same period caused blurred vision and a decrease in contrast sensitivity.  (+info)

Dose dependent reduction of erythroid progenitor cells and inappropriate erythropoietin response in exposure to lead: new aspects of anaemia induced by lead. (3/621)

OBJECTIVE: To determine whether haematopoietic progenitor cells and erythropoietin (EPO), which is an essential humoral stimulus for erythroid progenitor (BFU-E) cell differentiation, are affected by lead intoxication. METHODS: In male subjects chronically exposed to lead with and without anaemia, pluripotent (CFU-GEMM), BFU-E and granulocyte/macrophage (CFU-GM) progenitor cell counts in peripheral blood were measured with a modified clonal assay. Lead concentrations in blood (PbB) and urine (PbU) were measured by the atomic absorption technique, and EPO was measured with a modified radioimmunoassay. RESULTS: PbB in the subjects exposed to lead ranged from 0.796 to 4.4 mumol/l, and PbU varied between 0.033 and 0.522 mumol/l. In subjects exposed to lead with PbB > or = 2.896 mumol/l (n = 7), BFU-E cells were significantly reduced (p < 0.001) whereas the reduction in CFU-GM cells was only of borderline significance (p = 0.037) compared with the age matched controls (n = 20). The CFU-GEMM cells remained unchanged. Furthermore, BFU-E and CFU-GM cells were reduced in a dose dependent fashion, with increasing PbB or PbU, respectively. In the subjects exposed to lead EPO was in the normal range and did not increase in the presence of anaemia induced by lead. No correlations existed between EPO and PbB, PbU, or progenitor cells. CONCLUSION: The data suggest new aspects of lead induced anaemia besides the currently acknowledged shortened life span of erythrocytes and inhibition of haemoglobin synthesis. Two additional mechanisms should be considered: the reduction of BFU-E cells, and inappropriate renal EPO production in the presence of severe exposure to lead, which would lead to an inadequate maturation of BFU-E cells.  (+info)

Historical cohort study of a New Zealand foundry and heavy engineering plant. (4/621)

OBJECTIVES: To investigate the mortality of workers who had been exposed to asbestos, machining fluids and foundry work in a foundry and heavy engineering plant in the railway rolling stock manufacturing industry in New Zealand. METHODS: Historical cohort study design. RESULTS: For the total workforce of 3522 men employed between 1945 and 1991, follow up was 90% of person-years to 31 December 1991. Significantly increased standardised mortality ratios (SMRs) were found for all causes of death combined (SMR 1.07; 95% confidence interval (95% CI) 1.01 to 1.14), all malignancies (SMR 1.15; 95% CI 1.01 to 1.31), circulatory (SMR 1.16; 95% CI 1.07 to 1.27) and musculoskeletal diseases (SMR 3.06; 95% CI 1.39 to 5.84), all digestive cancers (SMR 1.29; 95% CI 1.04 to 1.59), all respiratory cancers (SMR 1.34; 95% CI 1.08 to 1.65), cancer of the oesophagus (SMR 1.97; 95% CI 1.01 to 3.45), and mesothelioma of the pleura (SMR 6.58; 95% CI 1.24 to 19.49). Three deaths from pleural mesothelioma were recorded, with latency times of 51, 53, and 57 years. There were no dose-response relations between exposure to asbestos, machining fluids or foundry work, or by duration of employment in the plant, and any cause of death. CONCLUSIONS: This study found small increases in risk for several causes of death among foundry and heavy engineering workers; however, these increases were small and the possible effects of smoking and other lifestyle factors could not be excluded. There was evidence of asbestos related disease in those involved in engineering work in the past.  (+info)

Modulating influence of cytochrome P-450 MspI polymorphism on serum liver function profiles in coke oven workers. (5/621)

OBJECTIVES: It was reported previously that topside oven workers with heavy exposure to coke oven emissions had increased serum activities of hepatic aminotransferase in one coke oven plant. This study was conducted to investigate the modifying effect of CYP1A1 MspI polymorphism on liver function profiles in coke oven workers. METHODS: 88 coke oven workers from a large steel company in Taiwan were studied in 1995-6. Exposure was categorised by work area: topside oven workers and sideoven workers. Liver function profiles including serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), r-glutamyl transpeptidase (GGT), alkaline phosphatase (ALP), and total bilirubin (BIL) were examined in the morning after personal exposure measurements. The MspI polymorphism was determined by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). RESULTS: Five of 23 (22%) topside oven workers and seven of 65 (11%) sideoven workers had the CYP1A1 MspI homozygous variant genotype. With sideoven workers with the combined wild type and heterozygous variant as the reference group in multiple regression models, it was found that topside oven workers with the combined traits had mean AST and ALT activities that were 21% and 46% higher (95% confidence interval (95% CI) 4% to 42% and 12% to 91%, respectively) than the reference group after adjusting for appropriate confounders. Also, topside oven workers with the homozygous variant trait had mean AST, ALT, and GGT activities that were 59%, 68%, and 157% higher (95% CI 21% to 109%, 6% to 168%, and 39% to 374%, respectively) than the reference group. The prevalence of an abnormal hepatocellular pattern (AST > 37 IU/l or ALT > 39 IU/l) was more common in the topside oven workers with the homozygous variant than in the sideoven workers with the other combined genotypes (adjusted odds ratio 9.9, 95% CI 1.2 to 82.3) after adjusting for appropriate confounders. CONCLUSIONS: The CYP1A1 MspI polymorphism may modify the biotransformation of coke oven emissions, which results in hepatocellular damage in coke oven workers.  (+info)

20 years of medical surveillance on exposure to allergenic and non-allergenic platinum compounds: the importance of chemical speciation. (6/621)

OBJECTIVES: Chloroplatinates are potent allergens but other soluble platinum compounds such as tetraammine platinum dichloride (TPC) do not provoke reactions in subjects who are sensitive to chloroplatinates. TPC has been used in the manufacture of autocatalysts for 20 years. This study analyses 20 year data on exposure to soluble platinum compounds and medical surveillance to confirm that TPC is not allergenic. METHODS: Workers in three distinct operations were exposed to soluble platinum compounds as chloroplatinates, chloroplatinates with TPC, or to TPC alone. Results of personal air sampling for soluble platinum compounds were compared together with the results of medical surveillance. RESULTS: The levels of exposure to soluble platinum compounds in each operation were comparable but the incidence of allergy was significantly different. In a subgroup of workers consistently exposed to chemical processes in each operation, the cumulative chance of being sensitised after 5 years of exposure was estimated as 51% for chloroplatinate exposure, 33% for mixed exposure, and 0% for TPC alone. The differences in sensitisation rates could not be explained by age, sex, and atopy. Nor could they be explained by the increased frequency of smoking in the workers with chloroplatinate exposure, despite the markedly higher risk of sensitisation in smokers. The differences could only be explained by the chemical stability of TPC. CONCLUSIONS: This study shows that the soluble platinum compound TPC is not allergenic under normal industrial conditions. Characterisation of the chemical compound (speciation) is essential to prevent stringent exposure limits being imposed for all soluble compounds on a generic basis.  (+info)

Point source sulphur dioxide peaks and hospital presentations for asthma. (7/621)

OBJECTIVE: To examine the effect on hospital presentations for asthma of brief exposures to sulphur dioxide (SO2) (within the range 0-8700 micrograms/m3) emanating from two point sources in a remote rural city of 25,000 people. METHODS: A time series analysis of SO2 concentrations and hospital presentations for asthma was undertaken at Mount Isa where SO2 is released into the atmosphere by a copper smelter and a lead smelter. The study examined 5 minute block mean SO2 concentrations and daily hospital presentations for asthma, wheeze, or shortness of breath. Generalised linear models and generalised additive models based on a Poisson distribution were applied. RESULTS: There was no evidence of any positive relation between peak SO2 concentrations and hospital presentations or admissions for asthma, wheeze, or shortness of breath. CONCLUSION: Brief exposures to high concentrations of SO2 emanating from point sources at Mount Isa do not cause sufficiently serious symptoms in asthmatic people to require presentation to hospital.  (+info)

Extremely low frequency magnetic fields and fertility: a follow up study of couples planning first pregnancies. The Danish First Pregnancy Planner Study Team. (8/621)

OBJECTIVES: To evaluate the impact of extremely low frequency (ELF) magnetic fields on markers of human fertility. METHODS: A follow up study of time to pregnancy, semen quality, and reproductive hormones was conducted among couples planning first pregnancies (36 males were welders and 21 were non-welders). The male and the female partner were monitored for exposure to ELF magnetic field by personal exposure meters. As summary measures of exposure the median value was calculated together with the 75 percentile value and the proportion of measurements exceeding 0.2 and 1.0 microT, respectively. Each summary measure was divided in three categories: low, medium, and high. RESULTS: Couples in which the man had a medium or a high proportion of measurements > 1.0 microT had a reduced probability of conception per menstrual cycle compared with the men with low exposure, but the result was only significant for the men with medium exposure. This finding was partly attributable to a high probability of conception per menstrual cycle among the men with low exposure compared with non-welders in the original cohort of 430 couples. Other summary measures were not related to probability of conception or other markers of fertility. A possible negative association was found between high probability of conception and female exposure measures based on the median, the 75 percentile, and the proportion of measurements > 0.2 microT, but no association was found with the proportion of measurements > 1.0 microT. CONCLUSIONS: The findings provide no consistent support for a hypothesis of a deleterious effect of low level ELF magnetic fields on markers of human fertility. However, due to the relatively small size of the studied population only large associations would be detected.  (+info)

Metallurgy in Eurasia originated in Southwest Asia due to the widespread adoption of, and experimentation in, pyrotechnology and the desire for new materials to serve as aesthetic visual displays of identity, whether of a social, cultural or ideological nature. This can be demonstrated through the early use of metal for jewellery and the use of ore-based pigments along with the continued use of stone, bone, and other materials for most tools. The subsequent appearance of metals throughout Eurasia is due to the acquisition of metal objects by individuals and communities re-inventing traditions of adornment, even in regions hundreds of kilometres from the nearest sources of native metals or ores. The movement of communities possessing metallurgical expertise to new ore sources and into supportive societies led to the gradual transmission of metallurgy across the Eurasian landmass. By the second millennium BC, metallurgy had spread across Eurasia, becoming firmly rooted in virtually all inhabitable ...

The blast furnace slag and the wet or dry charge may be injected into the feed end of the rotary kiln as separate materials or may be injected together without premixing at the feed end of the kiln.. Fifth, only slight chemical composition changes in the feedstock composition are required for normal feedstock to accommodate the blast furnace slag. This usually means that the lime content of the charge must be richer.. Sixth, the coarse blast furnace slag chemistry is transformed into the desired cement clinker structure during heat treatment in a rotary kiln by diffusion.. Seventh, significant energy savings are realized when the blast furnace slag is used because the blast furnace slag melts at low temperatures and does not require any grinding or milling of the blast furnace slag.. Eighth, the increase in cement clinker formation is almost proportional to the amount of blast furnace slag used.. Ninth, the environmental conditions of the rotary kiln process are improved due to the low volatile ...

The aim of this study was to assess the environmental effects of Moshyttan, one of the earliest known blast furnaces in Europe (ca. 11th century). The study was based on the analysis of three lake records in the immediate surroundings of the smelter. Fickeln lies directly downstream and is the main recipient of waterborne pollution. Mosjökälla lies directly upstream and served as the main water reservoir for the water-powered bellows. Kramptjärnen lies 1 km to the NW in a separate catchment and acts as a reference. The data includes 31 elements analyzed by X-ray fluorescence spectroscopy (XRF), organic content inferred from loss on ignition (LOI), biogenic silica (BSi) modeled from Fourier-transform infrared spectroscopy (FT-IRS) for all lakes and diatom counts for Fickeln. Two other studies provided dating of slag from the smelter and pollen- and geochemical data from Fickeln. The results show that the metallurgy and associated activities (e.g. agriculture, forest grazing and charcoal ...

N2 - Physicochemical behaviour of the pellets, sinters and its mixture (60% pellets: 40% sinter) is investigated by a series of smelting and quenching experiments. For all ferrous raw-material beds, three distinct stages of bed shrinkage occur due to indirect reduction, softening and melting. However, the characteristic nature (displacement, temperature and permeability) differ with the ferrous raw-material type. In mixed ferrous bed, the first and third stages are found to be controlled by the pellets (individual particle shrinkage) and sinter (slow melting rate), respectively. Second stage behaviour is initially observed to be close to the pellet and later to that of sinter. In mixed bed (upto ...

Despite their excellent balance of properties, titanium alloys are still a niche material whose range of applications is limited by the high cost of their manufacturing. With recent developments, powder metallurgy (PM) approaches, in particular the blended elemental (BE) route, are able to reduce considerably the cost of manufacturing while keeping a reasonable performance, mostly in terms of tensile strength and ductility. The cost reduction of the BE approach derives from the simplification of the process by removing a large amount of re-melting and ingot breakdown operations, regardless of the use of the approach as a net-shape technology. However, in terms of fatigue behaviour, the performance of these alloys is generally worse than conventional processes unless additional steps are applied.

Pressure powder metallurgy process for consolidating refractory or rhenium alloys using a reduced temperature and elevated pressure. Rhenium metal has high temperature strength and wear resistance but has a very high melting point as a pure metal and thus is difficult to use as a coating for many alloys having lower melting points. The reduced temperature and elevated pressure alloying process of the rhenium allows it to be used as a coating for other metal alloys, such as nickel and steel alloys, providing some high temperature and wear resistance due to the properties of the rhenium material in the coating.

The main finding of this study was that exhaled NO concentrations in non-smoking potroom workers were 63% higher than in non-smoking control subjects recruited from the same plant. The two groups were otherwise comparable for occurrence of asthma-like symptoms and use of β2-agonists. No subject in either group used corticosteroids. The potroom workers were somewhat younger than the controls (mean age 40 v 46 years), but concentrations of exhaled NO have not been shown to vary with age.12 Although the exhaled NO concentration in the non-smoking potroom workers was not as high as that found in symptomatic asthmatic subjects, it was comparable to the concentration observed in atopic subjects with bronchial hyperresponsiveness.18 In smokers, we found no difference in exhaled NO between potroom workers and controls. This may be because chronic cigarette smoking itself decreases exhaled NO, both in healthy19 and in asthmatic subjects.20 In mildly asthmatic subjects, the effect of smoking on exhaled ...
OBJECTIVES: To determine whether occupational exposure to chromite, trivalent chromium, or hexavalent chromium causes respiratory diseases, an excess of respiratory symptoms, a decrease in pulmonary function, or signs of pneumoconiosis among workers in an integrated chain of stainless steel production. METHODS: This cross sectional study was carried out in 1993 and the inclusion criterion was a minimum of eight years of employment in the same production department. A self administered questionnaire was collected, and spirometry, measurement of diffusing capacity, chest radiography, and laboratory tests were carried out by a mobile research unit. RESULTS: There were 221 workers in the exposure groups and 95 in the control group. The average duration of employment was 18 years. No significant differences in the odds ratios (ORs) of the symptoms were found between the exposure and the control groups.

OBJECTIVES: To determine whether exposure to five different occupational substances contributes to respiratory symptoms in aluminium smelter workers.. METHODS: A cross-sectional survey of 1,615 male employees of two Australian aluminium smelters was conducted in 1995. Subjects underwent spirometry and were asked about respiratory symptoms and the relationship of those symptoms to work. Their job histories were combined with a task exposure matrix to produce individual quantitative measures of cumulative exposure to fluoride, sulphur dioxide, inspirable dust, the benzene-soluble fraction of coal tar pitch volatiles (BSF), and oil mist.. RESULTS: After adjusting for smoking and age, we found that subjects with the highest cumulative exposure to fluoride (,0.16 mg/m(3) years) and inspirable dust (,2.9 mg/m(3) years) were two to four times more likely to report work-related wheeze and chest tightness than were unexposed subjects. Lower prevalence ratios for the same symptoms were seen with sulphur ...
ABSTRACT: This article summarizes an assessment of air sampling and analytical methods for both oil and water-based metalworking fluids (MWFs). Three hundred and seventy-four long-term area and personal airborne samples were collected at four plants using total (closed-face) aerosol samplers and thoracic samplers. A direct-reading device (DustTrak) was also used. The processes sampled include steel tube making, automotive component manufacturing, and small part manufacturing in a machine shop. The American Society for Testing and Materials (ASTM) Method PS42-97 of analysis was evaluated in the laboratory. This evaluation included sample recovery, determination of detection limits, and stability of samples during storage. Results of the laboratory validation showed (a) the sample recovery to be about 87%, (b) the detection limit to be 35 microg, and (c) sample stability during storage at room temperature to decline rapidly within a few days. To minimize sample loss, the samples should be stored ...
By Dr. Michael Berg, EMLab P&K Senior Molecular Biologist. Metalworking fluids (MWFs) are used in industrial machining and grinding operations to reduce heat and friction and to improve product quality. They are categorized into straight or neat oils, soluble oils, semi-synthetic and synthetic fluids. Generally, MWFs are complex mixtures containing a number of additives to improve performance and stability including emulsifiers, anti-weld agents, corrosion inhibitors, extreme pressure additives, buffers, dyes, odorants and biocides. In use, the fluid complexity is compounded by contamination with substances from the manufacturing process such as tramp oils, hydraulic fluids and particulates from grinding or machine operations. Furthermore, water-based MWFs may support microbial growth adding biological contaminants in the form of bacterial and fungal cells and their related byproducts such as endotoxins, exotoxins and mycotoxins. Each component of the complex mixture can contribute to health ...
Occupational exposure to nickel occurs mainly through inhalation of dust particles and fumes or through skin contact. Acute exposure to high levels of nickel by inhalation can cause severe damage to the lungs and kidneys. Prolonged exposure to nickel refinery dust among nickel refinery workers leads to an increased risk of lung and nasal cancers. Nickel refinery dust is a mixture including many nickel compounds as well as other inorganic substances. Nickel subsulfide is the major constituent in refinery dust from the smelting of sulfidic ores. Chronic dermal exposure to nickel can lead to dermatitis with complaints such as dry, irritated or itchy skin. Chronic inhalation exposure to metallic nickel and water-insoluble nickel compounds can result in respiratory effects, including decreased lung function and bronchitis. Chronic exposure to soluble nickel compounds by inhalation can also result in asthma cases.. Latency period between exposure and nickel related cancer varies from 13 to 24 ...

OBJECTIVE: To examine the incidence of occupational asthma in the seven aluminum smelters of Australia and New Zealand from 1991 to 2006.. METHODS: Incidence and exposure data were collected by survey from the smelters prospectively during the study period.. RESULTS: The incidence of occupational asthma across all smelters combined was highest in 1992 at 9.46/1,000/year, declining to 0.36/1,000/year in 2006; a 96.2% reduction. The incidence of occupational asthma was correlated with geometric mean total fluoride concentration, measured as personal samples from employees undertaking anode changing (r(s) = 0.497, P , 0.001).. CONCLUSIONS: The control of exposures, respiratory protection and pre-placement medical assessments undertaken during the study period seem to have contributed to the substantial decline in occupational asthma incidence.. ...

The Department of Mining Engineering had its conception in the 1867 aims of the Illinois Industrial Universitys Committee on Courses and Faculty, which listed the department as part of the proposed Polytechnic Department. Courses in mining engineering were offered in the Civil Engineering Department during the 1870-75 period. In 1885, the University faculty adopted and approved a B.S. program. The program had its first graduate in June 1887. With little student interest, the program lapsed in 1889. An attempt was made two years later to revive interest by offering a course for coal miners. A lack of response caused the Department to be abolished in 1891. In 1901, the Board requested Illinois members of Congress to support a bill promoting mining engineering. In June, 1909, the Illinois General Assembly passed an act calling for a Department of Mining Engineering with provision for instruction and extension work by the University. In 1911, the Department began to work closely with the State ...

The main target includes the ridge where steeply dipping Ordovician age quartzite is exposed over a strike length of approximately 850 meters. Geological mapping, geochemical sampling, and surveying identified a series of white quartzite outcroppings (Wonah Quartzite Formation) that form 2 lenses, the Central Zone that has been traced for approximately 500 m, and South Zone traced for 350 m along strike. The Central and South Zones consist of a highly competent quartzite unit that trends N to NNE, is approximately 50 meters in width, and has a steep east dip. There is an ESE trending fault between the Central and South Quartzite Zones that has an approximate 200 m sinstral, horizontal displacement. A total of 11 rock chip quartzite samples were taken from the Central & South Zones by MGX VP Exploration Andris Kikauka (P. Geo.) shortly after acquisition in 2015. Rock chip samples were analyzed by ALS Minerals, North Vancouver, BC, using Li Borate fusion, whole rock analysis ME-XRF-06 (XRF26), ...

Tartaglia proceeded by cutting the trajectory of the cannonballs into different portions and then identifying them with the two different sorts of motion his conceptual apparatus was able to provide. The theory of ballistics that emerged from this operation was basically an analysis of the portion of the trajectory that was associated with violent motion. On the basis of this procedure, Tartaglia was able to draw quantitative consequences not only concerning the maximal range, but also concerning the variation in the destructive power of cannon shots in dependence on the distance between target and cannon, and on the elevation of the artillery.. The tests executed by means of cannons, around which Tartaglia narrates in his work, merely symbolize the background against which the new science of ballistics emerged. Clearly, and as it has already been stated by several scholars, the background knowledge involved in the process of emergence of the theoretical ballistics was represented by the ...

So one of the unions representing refinery workers wants to make safety improvements part of its latest round of contract talks.. At noon today, Bay Area members of the United Steelworkers plan to rally at Chevrons headquarters in San Ramon. Their union is in the midst of contract talks with multiple oil companies - not just Chevron - and wants its workers to have a bigger role in how refineries enforce safety rules.. People who work in oil refineries are eight times more likely to die on the job than in any other type of manufacturing in the nation, said Jeff Clark, secretary treasurer of United Steelworkers Local 5. That needs to improve.. Local 5 represents about 1,500 employees of Bay Area refineries, including Chevrons Richmond refinery.. Chevron, for its part, says its willing to talk safety, although a company spokesman declined to get too specific..
