“…There are some researches investigating the risk of accidents from acetone storage. He et al studied the suitable value of air change per hour (ACH) for laboratory ventilation under acetone spills 10 . The authors reported that the increase of ACH is a profit for the clearance of pollutants when fume hoods are closed.…”

The leakage of acetone from damaged tanks can threaten workers, surrounding facilities, and the environment. The safe storage of acetone is of vital importance for emergency planning and response. This paper focused on the effects and consequences of acetone leaks from a 200 m3 storage tank in the summer and winter seasons by the employment of Areal Locations of Hazardous Atmospheres. The hazard zones classified as red threat zone, orange threat zone, and yellow threat zone were determined and analyzed. Results showed that the risk distribution of the toxic acetone vapor cloud in summer was greater than those in winter. The summer and winter seasons have no significant effect on the thermal radiation intensities from pool fire and the Boiling Liquid Expanding Vapor Explosion (BLEVE) scenario. The maximum distance of toxicity, flammability, and thermal radiation from the pool fire and BLEVE scenario for the acetone leakage were 547, 111, 16, and 1100 m, respectively. The results would provide guidance for decision‐makers in safety management and emergency response to reduce hazards.

“…He et al studied the suitable value of air change per hour (ACH) for laboratory ventilation under acetone spills. 10 The authors reported that the increase of ACH is a profit for the clearance of pollutants when fume hoods are closed. The simulated scenarios with a small chemical spill of about 50 ml acetone are not suitable for chemical plants.…”

“…Most studies of aircraft painting workshops focus on workers' hearing, ignoring the impact of pollutants on workers' health. In commercial aircraft painting workshops, increasing the air volume of ventilation systems is a common strategy to control pollution, which however is not economical and efficient (He et al, 2021;Lin et al, 2009). Therefore, field-testing in aircraft spraying workshops is necessary to collect data for a better understanding on the pollutant release characteristics.…”

“…A laboratory is a place to apply a scientific theory, proof of trials, theoretical testing and so on by using adequate completeness and quality tools (Emda, 2017). Chemical laboratories generally use chemicals, chemical spills and gas leakage which have been the main safety concerns, and which occasionally happen due to human error or equipment failure (He et al, 2021).…”

Introduction: The number of chemicals is increasing every year. Laboratories record work accidents because there are several chemicals that are not labeled and unidentified but are stored in an inappropriate place. The Globally Harmonized System (GHS) is a Global System for standardizing criteria and harmonizing hazard classification systems, Safety Data Sheets (SDSs) and Labeling. This research aims to assess and evaluate the implementation of the GHS at the Occupational Safety Division of the Manpower and Transmigration Department Surabaya. Methods: This research was a descriptive observational study. Data were collected by assessing 80 types of chemicals through assessment sheets and an interview with the analyst supervisor, who had responsibility and authority in the application of the GHS. This research aims to apply the GHS with hazard classification variables, SDS availability and suitability, and labelling availability and suitability. Results: The results showed that the implementation of the GHS at the Occupational Safety Division of the Manpower and Transmigration Department Surabaya was 66.67%, categorized as good, with a good availability and suitability assessment of SDSs of 91%, and a good availability and appropriateness assessment of labelling of 98.1%. Conclusion: The results showed that the Occupational Safety Division of the Manpower and Transmigration Department Surabaya has been very good at implementing the GHS, but some points must be made to maintain and improve the application of the GHS as an effort to prevent accidents with hazard communication.
