    <p>Laboratory-based research activities frequently involve hazardous materials and operations, which are prone to accidents or injuries. While risk assessment is a necessary step in the research plan, it is often difficult to recognize all potential hazards involved in laboratory work, including those in the preparation and clean-up phases. In this study, we investigate the performance of deep learning models in predicting potential hazards in laboratory work. As a training dataset, actual laboratory accident reports collected from national universities in Japan are labeled with the most suitable hazards. The trained models read a text of laboratory work plan as an input and predict the possible primary and secondary hazards as outputs. The model that combines Bidirectional Encoder Representations from Transformers (BERT) with Bidirectional Long Short-Term Memory (BiLSTM) shows higher performance compared to that of its constituent models individually. The trained models can therefore potentially be used as a core component of risk assessment tool and safety training, enabling junior researchers and students to recognize potential hazards and assess possible accident risks in their laboratory work, thus reducing the frequency of accidents and injuries.</p>

  3. Eleven risk elements rationalizing laboratory accidents at universities Reviewed Open Access

    <p>Accidents during research and educational activities are reported to universities in order to improve the safety management and training. This study reveals hidden risk elements involved in laboratory accidents. A handbook for safety at Nagoya University “Safety Lessons Learned from Accidents - 85 Selected Cases in Nagoya University” is a summary of over 1,500 reports of general and laboratory accidents from FY2004 to FY2017, and 66 various cases of the laboratory accidents in the handbook are subjected to the analysis. Description of each case illustrates the causes of laboratory accidents, such as inappropriate handling of hazardous materials, poor laboratory conditions, high-risk operations, and ignorance of rules. In our analysis, the causes of each laboratory accident were classified into the three risk factors: hardware, human, and software, then we rationalized the causes with the risk elements as subcategories of the risk factors. Some of the elements were frequently observed in the 66 cases, which highlight important points when improving laboratory safety. The results of our analysis also show that multiple risk elements are involved in all the cases of laboratory accidents. Increasing the number of risk elements in the laboratory also tends to result in a serious laboratory accident. In addition, the risk elements were further categorized into the three roles: inducer, initiator, and promotor. Multiple risk elements as inducers are present under the normal laboratory conditions. Involvement of initiator risk elements is considered to set unsafe conditions, and the promotor risk element amplifies the severity of accident. We suggest that the risk elements concerning especially to education and communication are important when considering of safety activities in the laboratory, such as safety training, sharing hazard information, risk assessment, laboratory inspection, and selection of personal protective equipment.</p>

  4. Measurement of indoor carbon dioxide concentrations when using a carbon dioxide fire extinguisher in a room Reviewed Open Access

    <p>Carbon dioxide fire extinguishers are effective against small fires and fires from electrical equipment, however, the danger of carbon dioxide poisoning must be kept in mind especially when the fire extinguishers are used indoors. In this study, we measured concentrations of carbon dioxide and their changes over time with carbon dioxide monitors (measurable range of 0 to 9,999 ppm) when using a carbon dioxide fire extinguisher indoors. The concentration at a height of 50 cm from the floor exceeded 10,000 ppm approximately 20 seconds after discharge of the extinguisher. When the window was open for ventilation, it exceeded 10,000 ppm for about 40 seconds then decreased rapidly. In contrast, when the window was closed, it exceeded 10,000 ppm for more than 200 seconds, and the subsequent decrease in concentration was gradual. For the concentration exceeding 10,000 ppm, the maximum concentrations were estimated using exponential curves. It was estimated to be approximately 20,000 ppm and 40,000 ppm when the window was open and closed, respectively. Concentrations at a height of 150 cm from the floor were up to 4,000 ppm regardless of whether the window was open or closed. In general, headaches and dizziness occur when the carbon dioxide concentration exceeds 30,000 ppm, and unconsciousness occurs when the concentration exceeds 100,000 ppm. Our results suggest that the carbon dioxide concentration near the floor is relatively high and there is a risk of poisoning, but it is not too high to immediately lose consciousness. It should be avoided to directly discharge a carbon dioxide fire extinguisher to the face, but our results indicate that it is considered safe to use it if there is ventilation such as by opening windows and if it is not used in an extremely narrow space.</p>

    Expansion of global research activities has become a critical task for Japanese universities; however, it associates with a challenge of ensuring that non-Japanese researchers comply with regulatory and safety requirements, such as the chemical management. A questionnaire survey was conducted to grasp an understanding and impression of members at an international university regarding chemical management including Japanese regulations and an electronic system. Majority of the respondents are not satisfied with regulatory information provided by the Japanese government for non-Japanese speakers. Those who have experienced in countries other than Japan show some understandings of the Poisonous and Deleterious Substances Control Act. In contrast, the results of survey show the low levels of understanding of other regulations. It reveals that non-Japanese researchers are not familiar with recording the usage of chemicals and taking the periodical medical examination for those who handle harmful chemicals. The results of survey also suggest that the electronic system available in English and Japanese is a useful tool for non-Japanese researchers to manage chemicals in compliance with Japanese regulations. Overall, we present initiatives to improve the chemical management in compliance with the regulations for non-Japanese researchers, which would promote internationalization of universities and global research collaborations in Japan.

    <p>We have developed a database of chemical substances, pathogens, and toxins (8,595 entries in total) that are regulated or defined in 22 Japanese statutes and guidelines. This database is equipped with a search function allowing users to search keywords such as names of statutes, chemical substances, pathogens, or toxins. In order to enhance convenience and to reduce chances of search failures, the keyword entry field is equipped with autocomplete functionality. Results of keyword searches based on chemical substances, pathogens,or toxins are displayed with the names of regulating statutes and a summary of legal restrictions/requirements. To facilitate its use by foreign researchers and students, users can search controlled substances, of interest either in Japanese or English. While extracting data regarding controlled substances from those statutes, we discovered that some provisions do not explicitly identify regulated materials,but only specify physical properties thereof. Accordingly, it is not possible to grasp the entire regulatory framework defined by the statutes based solely upon a database of regulated substances. However, development of the database allowing users to easily and quickly find out whether there are any regulations governing specific substances and the intent of such controls, even in English, should improve compliance, safety, and health at Japanese universities and research institutions.</p>

    Risk assessment is to estimate the risks associated with handling chemicals and laboratory work in advance then evaluate the measures to reduce the risks in order to prevent health problems and accidents. Risk assessment has drawn much attention as part of safety training to prevent laboratory accidents during research and educational activities. However, risk assessment on various chemicals and laboratory work is a time-consuming process. This study aims to generate a program for quick risk assessment using deep learning. A model has been generated by analyzing past laboratory accidents, which has the ability to predict risks in the input of laboratory work.
