Abstract

Laboratory workers have potential health and safety risks, health risks in laboratories are potential health and safety risks, and health risks in laboratories are related to exposure to hazardous chemicals. Chemicals often used in laboratory testing are organic solvents such as benzene, toluene, and xylene which have risks to workers' health. Chemical health risk assessments are important for assessing the potential health and safety hazards of workers using the approach cross-sectional which refers to the method Chemical Health Risk Assessment DOSH, Malaysia. Data collection was carried out qualitatively starting with identifying dangerous chemicals, then observing the use of chemicals, followed by assessing the level of health risks, and determining the adequacy of control action priority for inhalation and dermal exposures respectively. The research results at the PT show that the risk level for inhalation exposure is 12 (moderate risk) and the risk level for dermal exposure is 2 (moderate), but still requires improvement in existing risk controls.

Abstract

The musical instrument manufacturing industry is an industry that has risks and dangers from using chemicals. The chemicals used include solvents and adhesives. Solvents are used as mixing and diluting materials for the wood painting process. Adhesives are used when connecting wooden parts to make a musical instrument. The solvents used are 1,2,4-trimethylbenzene, 2-butoxyethanol, 2-ethoxyethyl acetate, 4-methylpentan-2-one, cumene, cyclohexanone, ethyl acetate, ethyl benzene, mesitylene, naphthalene, n-butyl acetate, solvent naphtha (petroleum), toluene, and xylene. The assessment of chemical health risks refers to the Chemical Health Risk Assessment (CHRA) DOSH Malaysia in 2018. This study is qualitative because the determination of the level of hazard, exposure, and evaluation are carried out qualitatively. Data collection begins with chemical identification, then conducting observations and interviews, followed by health risk assessment, adequacy of control, and determination of action priorities for each inhalation and dermal exposure. The results of the study at PT. XYZ for inhalation exposure obtained a Risk Rating value of 6 (moderate) to 16 (high), while for dermal exposure the value was moderate 1, moderate 2, and high 1. The coloring process with paint has an action priority of 3 while the washcoat, wapping, and logo installation processes have an action priority of 2 which requires improvement of existing risk control.

Abstract

Introduction: Conventional tofu production involves various manual handling tasks which increases the risk of musculoskeletal disorders (MSDs). A previous study found a very high risk of MSDs in tofu manufacturing, especially in the filtering task with a REBA score of 13. Aims: This study aims to evaluate the risk of MSDs in tofu factory workers. Methods: Workplace observations and unstructured interviews were conducted at two traditional tofu factories (X and Y) and a more modern silken tofu factory to identify the risk of MSDs. The Nordic Musculoskeletal Questionnaire and the Quick Exposure Check (QEC) method were used to determine the prevalence and risk of MSDs. A total of 52 workers voluntarily participated in this study. Results: The traditional and silken tofu manufacturing processes involved seven and fifteen tasks, respectively. This study found that workers in the traditional tofu factories had a higher prevalence of MSDs than those in the silken tofu factory. In the past 12 months, traditional tofu factory workers reported MSDs in their lower back (94.4%), right shoulder (77.8%), and neck (61.1%). On the other hand, silken tofu factory workers reported MSDs in their lower back (81.3%), right shoulder (62.5%), and upper back region (56.3%). According to the QEC method, grinding and filtering were identified as two tasks with a very high risk of MSDs in the traditional factories. In addition, transferring tofu crates from cold water to hot water tub in the silken factory was identified as a very high risk of MSDs. Conclusion: Intervention is necessary for tasks with a very high risk of MSDs in small tofu factories.

Abstract

A risk assessment of gamma radiation and radon gas exposure is carried out in the uranium exploration tunnel area to protect workers from the ionizing radiation hazards in the workplace. Measurement of gamma-ray exposure and radon gas concentrations were carried out in Remaja uranium exploration tunnel and around the workers camp in Kalan Area, West Kalimantan. Gamma exposure was measured using a gamma survey meter while radon (222Rn/220Rn) using RADUET passive detector. The concentrations of radon and thoron gas inside the tunnel generally are high, ranging from 188.84 to 495.86 Bq/m3 (375.80 Bq/m3 average) and 58.07 to 340.73 Bq/m3 (189.80 Bq/m3 average) respectively. These values are above the radon reference level (300 Bq/m3)which is recommended by the International Commission on Radiation Protection (ICRP). The annual gamma effective dose reaches 147.88mSv inside the tunnel. This value is exceeding the 20 mSv dose limit value for workers. It is necessary to control the exposure by fulfilled the principle of “as low as reasonably achievable” (ALARA) and external radiation protection to secure workers inside the tunnel from a health issue caused by gamma-ray, radon, and thoron exposures.

Abstract

The laboratory is an experimentation or testing workplace that requires careful behavior in using equipment and material. One of the types of chemicals in the laboratory is an organic solvent as a solvent for other chemicals. The potential risk of breast cancer in female laboratory workers in this cohort study is exposure to organic solvents. Organic solvents that are often used in the laboratory are benzene, toluene, and xylene (BTX). Given workplace exposure to the chemicals benzene, toluene, and xylene, as well as the health hazards posed by these chemicals, a health risk assessment by inhalation using the Singapore SQRA technique is required to assess the amount of risk of chemical exposure to the health of workers at PT. X. Using a questionnaire that corresponds to The German Q18 Questionnaire to collect data on the health complaints of laboratory employees with neurotoxic symptoms. Inhalation and air sampling in the workplace were the first steps in the research. Data from sampling is analyzed to establish the degree of hazard (Hazard Rating), exposure (Exposure Rating), and risk (Risk Rating). Benzene, toluene, and xylene exposure levels were 1.6, 2.0, and 2.1, respectively. Benzene has a danger rating of 3 (moderate), while toluene and xylene have a risk rating of 2 (low risk). In terms of the percentage of respondents with positive neurotoxic symptoms or who answered "yes" to five or more questions on the questionnaire, 25% (1 respondent) and 75% (3 respondents) had negative neurotoxic symptoms.

Abstract

Eye strain is a condition where the eyes are strained due to prolonged overuse, especially in computer-based activities. NIOSH states that about 75 - 90% of computer users who spend three hours or more complaining of visual impairment. A study by Kowalska et al (2011) on office workers who use computers intensely stated that the prevalence of eye strain in female workers was 50,7% and in men was 32,6%. This study aims to determine the relationship between illuminance, reflectance, and work area contrast on eye strain complaints in office employees at PT. X. This research was conducted from April - June 2023 with a total sample of 134 employees by simple random sampling. The design used in this research is cross-sectional and data collection is carried out by distributing questionnaires, which were adopted from Haeny (2009) and Ramadhani (2012), and direct measurements using a lux meter. Results showed that there were 113 employees (84,3%) complaining of eye strain with the most common symptom felt by them was tension in the neck and shoulders (43,3%) and the least common symptom was pain in the eyelids (8,2%). The results of bivariate analysis showed that there was a relationship between illuminance (p-value = 0,000), reflectance (p-value = 0,001), contrast (p-value = 0,027), work duration (p-value = 0,000), and age (p-value = 0,022), but there was no relationship between visual impairment (p-value = 0,749) and history of eye health problems (p-value = 0,918) to eye strain complaints.
