Exploring the system capacity to meet occupational health and safety needs: the case of the ready-made garment industry in Bangladesh.

BACKGROUND: Since the 2013 Rana Plaza incident in Bangladesh, the government of Bangladesh has been under pressure to improve health and safety conditions for workers in the ready-made garment industry. Its efforts have focused heavily on structural safety of the buildings but have largely ignored broader occupational health system issues. This qualitative study explores contextual factors and system challenges that create barriers for ensuring a healthy and safe workplace in the ready-made garment industry in Bangladesh. METHODS: Data were collected through key informant interviews (n = 14) with government officials from the Department of Inspection for Factories and Establishments (DIFE), factory employers, factory doctors and representatives from the Bangladesh Garment Manufacturers and Exporters Association (BGMEA). A thematic analysis was conducted using Atlas-ti v 5.2. RESULTS: A thematic analysis suggests that the capacity of the DIFE to provide adequate occupational health services remains a problem. There is a shortage of both appropriately trained staff and equipment to monitor occupational health and safety in factories and to gather useful data for evidence-based decision-making. Another barrier to effective occupational health and safety of workers is the lack of cooperation by employers in recording data on workers' health and safety problems. Finally, government officials have limited resources and power to enforce compliance with regulations. Such deficiencies threaten the health and safety of this important, largely female, working population. CONCLUSION: This case example focused on the valuable ready-made garment industry sector of Bangladesh's economy. It identifies the critical need for occupational health system strengthening. Specifically system capacity needs to be improved by both increasing human resources for in-factory hazards and health monitoring, regulatory inspection, enforcement, and improved training of government officials around monitoring and reporting.

Needs assessment regarding occupational health and safety interventions among textile workers: A qualitative case study in Karachi, Pakistan.

OBJECTIVE: To determine the perceived health and safety needs identified by textile workers, managers and experts as well as direct observation of the prevailing health and safety practices in the textile industry. METHODS: The qualitative study using the needs assessment conceptual framework was conducted in July-August 2015 in Karachi, and comprised focus group discussions with textile workers, in-depth interviews with factory managers and health and safety officers, and key informant interviews with relevant stakeholders and experts. A walk-through survey was also conducted in selected mills for which the Checklist of hazards in textiles was used. RESULTS: A total of 6focus group discussions, 6 in-depth interviews and 5 key informant interviews were conducted. Workers were found to have limited knowledge of occupational hazards, preventions and diseases. They identified lack of awareness and non-existent safety mechanisms as areas for improvement. Managers thought preventive practices and health services were not standardised while influence of buyers in the form of international business regulations and legislations were thought to be the enabling factors for enforcing health and safety standards. Poor governance, lack of knowledge regarding labour rights, low literacy level, poor compliance and low wages were the barriers for health promotion at workplace, as identified by the experts. Walk-through survey found mechanisms in place for fire safety, but the workers and managers were generally not using Personal Protective Equipment despite the presence of several hazards at workplace. CONCLUSIONS: There was found a need for context-specific occupational health and safety interventions at individual, organisational and policy levels.

Cross-sectional study on the endotoxin exposure and lung function impairment in the workers of textile industry near Lahore, Pakistan.

OBJECTIVE: To examine the effects of airborne endotoxin on lung function impairment in exposure-response relationships among the workers of textile industry. METHODS: The cross-sectional study was conducted at Lahore College for Women University, Lahore, Pakistan, from January to August 2014, and comprised textile mill workers. The participants were divided into exposed and control groups. A questionnaire was used to ask workers about the potential adverse health effects of their occupation. The pulmonary function test was carried out by spirometer. Endotoxin levels in the samples were determined using the key quality characteristics limulus amebocyte lysate. The data was analysed to determine the correlation between the endotoxin exposure duration and pulmonary function test parameters. RESULTS: There were 200 subjects subdivided into 100 each inexposed and control groups. Overall, 160(80%) were not aware of safety measures and the remaining 40(20%) were partially practising. Changes in pulmonary function due to endotoxin exposure showed decreased force vital capacity, flow rate and peak expiratory flow parameters significantly different (p<0.05, p<0.001). The endotoxin concentration was between 12EU/m3 and 300EU/m3. Airborne endotoxin concentrations in textile plants exceeded the Dutch health-based guidance limit of 90EU/m3 and was associated with respiratory health effects. CONCLUSIONS: Prolonged exposure to airborne endotoxin caused constant lung impairment. Proper safety measures should be adopted to avoid the inhalation of cotton dust.

Differential scanning fluorimetry illuminates silk feedstock stability and processability.

The ability to design and implement silk feedstock formulations for tailored spinning has so far eluded the bioengineers. Recently, the high throughput screening technique of differential scanning fluorimetry (DSF) demonstrated the link between the instability transition temperature (Ti) and the processability of the silk feedstock. Using DSF we screened a large set of chemicals known to affect solvent quality. A multivariate analysis of the results shows that, regardless of the diversity of chemicals, three groupings are significantly distinguishable: G1 = similar to native silk; G2 = largely dominated by electrostatic interactions; and G3 = dominated by chelating interactions. We propose a thermodynamic analysis based on a pre- and post-transition fit to estimate the van't Hoff enthalpies (ΔHv) and the instability temperature (Ti). Our analysis shows that the ΔTi and ΔHv values were distinct: G1 (ΔTi = 0.23 ± 0.2; ΔHv = -159.1 ± 5.6 kcal mol(-1)), G2 (ΔTi = -7.3 ± 0.7; ΔHv = -191.4 ± 5.5 kcal mol(-1)), and G3 (ΔTi = -19.9 ± 3.3; ΔHv = -68.8 ± 6.0 kcal mol(-1)). Our analysis further combined the ΔTi value and the ΔHv value using stability ΔΔG to find that G1 only marginally stabilizes native silks (ΔΔG = -0.15 ± 0.04 kcal mol(-1)), whereas G2 and G3 destabilize native silk (ΔΔG = 3.8 ± 0.11 and ΔΔG = 3.8 ± 0.3 kcal mol(-1), respectively). Here our analysis shows that native silk has a complex multistep transition that is possibly non-cooperative. However, all three groupings also show a direct and cooperative transition with varied stabilization effects. This analysis suggests that native silks are able to sample multiple substates prior to undergoing (or to delay) the final transition. We conclude by hypothesizing that the observed energetic plasticity may be mediated by a fragile packaging of the silk tertiary structure that is readily lost when the solvent quality changes.

A passive noise control approach utilizing air gaps with fibrous materials in the textile industry.

BACKGROUND: Noise pollution is currently a major risk factor in industries in both developed and developing countries.The present study assessed noise pollution in the knitting industry in Iran in 2009 and presented a control method to reduce the rate of noise generation. METHODS: The overall noise level was estimated using the network environmental noise assessment method in Sina Poud textile mill in Hamadan. Then, frequency analysis was performed at indicator target stations in the linear network. Finally, a suitable absorbent was recommended for the ceilings, walls, and aerial panels at three phases according to the results found for the sound source and destination environment. RESULTS: The results showed that the highest sound pressure level was 98.5 dB and the lowest was 95.1 dB. The dominant frequency for the industry was 500 Hz. The highest and lowest sound suppression was achieved by intervention at 4000 Hz equivalent to 14.6 dB and 250 Hz in the textile industry. CONCLUSIONS: When noise control at the source is not available or insufficient because of the wide distribution of the acoustic field in the workplace, the best option is to increase the absorptive surface of the workplace using adsorbents such as polystyrene.

Trades of dangers: a study of asbestos industry transfer cases in Asia.

BACKGROUND: In a study of asbestos industry transfers in Asia, we examined the transfer of health and safety measures at the time of industry transfer and resulting health outcomes thereafter. METHODS: Field surveys were conducted in Japan, Germany, Indonesia, and South Korea over a 5 year period beginning in 2007. The surveys involved interviews and field assessments of health and safety conditions. RESULTS: Even when there were transfers of entire engineering plant processes, we observed that the health and safety measures that should have accompanied the transfer, including technical capacities of risk assessment and management, regulatory protection, and cultural practices, were not actually transferred. According to work environment assessment records, there were differences in airborne asbestos levels of approximately 5-6 fibers/cc between the exporting and importing sides of the transfer. This amounted to a 10 years of time delay in comparable health and safety conditions. These differences resulted in repeated adverse health consequences at each factory operation site. CONCLUSIONS: Dangerous transfers of asbestos industry technology have occurred repeatedly over the years with the result that Asia has become the largest consumer of asbestos in the world. No effective internationally accepted safety measures have been introduced in the region. The study results support the need for both improved public awareness and international cooperation, such as sharing of substitute material technologies by the exporting countries, and provide the rationale for the creation of an Asian fund for asbestos victims.

Economic evaluation of a participatory ergonomics intervention in a textile plant.

In this study we report on the economic evaluation of a participatory ergonomics process undertaken at a clothing manufacturer in Southwestern Ontario, Canada that employs approximately 300 workers. We undertake a cost-benefit analysis from the company perspective. Intervention costs amounted to $65,787 and intervention benefits $360,614 (2011 Canadian dollars). The net present value was $294,827, suggesting that the intervention was worth undertaking based on the costs and consequences over the measurement period spanning more than four years. Based on these costs and benefits, the benefit-to-cost ratio is 5.5. Overall, the findings from this study suggest that participatory ergonomics interventions can be cost beneficial from the company perspective. Even though the changes were typically low-cost and low-tech interventions implemented by the plant mechanics and maintenance personnel, benefits were realized on both the health and financial fronts.

Low-cost electronic microwave calibration for rapid on-line moisture sensing of seedcotton.

In order to improve rapid on-line moisture sensing of seedcotton in cotton gins, a means by which to establish a reliable low-cost wide-band electronic calibration is critically needed. This calibration is needed to center the circuit due to changes in the internal signal delays and attenuation drift caused by temperature changes in the various system components and circuit elements. This research examines a hardware technique for use in conjunction with microwave reflective sensing probes having an extended bandwidth from 500 MHz through 2.5 GHz. This new technique was validated experimentally against known electrical propagation delay standards. Results of the measured propagation delay with this type of automatic electronic calibration method was found to agree with results using a vector network analyzer with a traditional S11 single port error correction calibration methodology to within 4% of the measurement, 95% confidence, with a standard error of +/-18.6 ps for the delay measurements. At this level of performance, the proposed low-cost technique exhibits superior performance, over the typical geosciences time-domain reflectometer "TDR", instruments in common use in soil moisture testing and is suitable for use in cotton gin moisture sensing.

Development of a job exposure matrix (JEM) for the textile industry in Shanghai, China.

We developed a job exposure matrix (JEM) for the Shanghai textile industry constructed along three axes: industry sector, textile process, and hazardous agent. We assessed 35 different categories of dust, chemical, and physical agents for 149 textile processes within nine industry sectors: cotton, cotton/synthetic, cotton/other (nonsynthetic), wool, silk, synthetic, mineral, other mixed (e.g., wool and synthetic), and nonproduction. The JEM was constructed from two components: a priori assessment of the textile process by a team of U.S. industrial hygienists, and the prevalence of exposures reported by Chinese industrial hygienists in specific textile processes within the factory. The JEM was applied to an ongoing case-cohort study of cancer in women textile workers. The JEM assessed only dichotomous exposure (ever/never), and could be coupled with cumulative exposure by years of employment. The most common exposures in cotton mills were cotton dust and solvent exposures. Dyeing processes had the highest frequency of exposures, including solvents, acids, bases and caustics, bleaching agents, dyes, dye chemicals and intermediates, and formaldehyde. Only two processes were identified with formaldehyde exposure, beck dyeing and resin finishing. The most prevalent exposures among the subcohort, occurring in more than 60% of the women, were electromagnetic fields, lubricants, and cotton dust. More than one-third of subcohort subjects were also exposed to synthetic fiber dust, and slightly less than one-third of women were exposed to endotoxin. This JEM could be applicable for epidemiologic research in other textile industries.

Female garment factory workers in Cambodia: migration, sex work and HIV/AIDS.

Female garment factory workers in Cambodia are more exposed to HIV/AIDS than previously thought. Although HIV/AIDS epidemics are fast spreading in Cambodia, relatively little is known about the sexual health of women other than those perceived as commercial sex workers or married women of reproductive age. In-depth interviews with 20 unmarried female garment factory workers, who reported to have engaged in multi-partnered sex through direct or discretionary commercial sex occupations, demonstrate that they are exposed to HIV-risk created along the gradients of power. Low socioeconomic status (low education, meager factory wage and high dependency rate at their rural households) and obligations as daughters to provide for the family mainly determine their entry into sex work. At the location of sex work, they are subjected to physical violence, alcohol and drug use, both self-taken and forced, and receive meager wages. In a society where women are expected to be virtuous and obedient to parents and husbands, these workers are motivated to identify male sex partners in paid sex as "sweethearts" rather than "guests." These factors contribute to low consistency of condom use. This paper demonstrates the complex interrelationships between power, cultural definitions of intimacy and economic dependency, which structure sexual relationships and the risk of HIV/AIDS.

Toxicity-based criteria for the evaluation of textile wastewater treatment efficiency.

Brazilian textile mills import wastewater treatment technologies, performances of which are generally evaluated only on a physicochemical basis. Thus, a battery of bioassays was used to evaluate the performance of an ozonation system to treat textile effluents. Comparative toxicological profiles for bacteria (Vibrio fischeri), algae (Scenedesmus subspicatus), daphnia (Daphnia magna), fish (Poecilia reticulata), and plants (soybean--Glycine max, rice--Oryza sativa, and wheat--Triticum aestivum), as well as genotoxic effects (Vicia faba micronucleus assay), are presented for both raw and ozonated textile effluents. The relative sensitivity of bioassays (or end points) to textile effluents found in this study in decreasing order was plant enzymes > bacteria > algae daphnids approximately = plant biomass approximately = germination rate > fish. No significant genotoxic effect was found. We have concluded that ozonation was relatively effective in reducing toxicity of textile effluents. Bioassays used in this study proved to be sensitive and reliable tools for determining the toxicity of industrial effluents, and thus they can be used to evaluate emerging technology efficiency.

Effects of skirting on yield, fineness, and value of wool from fine-wool range ewes.

Eighty-one mixed-age (2 to 8 yr old) Rambouillet ewes (58.5 kg, SD 5.9 kg) were randomly assigned to three treatment groups that contained similar numbers to study the effects of wool skirting on clean yield, fiber diameter, and prices received for fine wool. The sheep were managed as a single flock on an experimental ranch close to Barnhart, TX during the 4-yr study. Two fleece-skirting techniques (SK1 and SK2) were compared with a control procedure in which fleeces were not skirted before packaging (original bag, OB method). Skirted wools were higher yielding (P < .05) and contained less vegetable matter (P < .05) than skirts. However, clean yield and vegetable matter content of skirted and OB wools were not different (P > .05). Weight-averaged prices received for grease wool from the SK1, SK2, and OB treatments over the 4-yr period were 4.49, 4.36, and 3.83 $/kg, respectively. Prices received for both types of skirted wool plus skirts were higher (P < .05) than prices received for OB wool.
