Perception of Firefighters on Risk of Exposure to Respiratory Health Hazard: A Qualitative Analysis in Malaysia

Firefighters are exposed to multiple occupational hazards, where one of the hazards is chemical hazard that can affect the respiratory system. However, little is known regarding the perception of firefighters on the source of exposure to respiratory hazards, particularly in Malaysia. This work aims to explore the firefighter’s perspective on respiratory hazard exposure and to examine the compliance of the use of personal protective equipment (PPE). In-depth interviews were employed among 12 firefighters at Fire and Rescue Department of Malaysia in September 2020. The interview recordings were transcribed verbatim and of thematic analysis done via the NVIVO 12 programme. All participants were Malay, male, and married. The respiratory hazard exposure perceived can be divided into occupational source (e.g. exposure to smoke from firefighting, fire training, firefight demonstration, commuting, firefight vehicles: chemicals and dust) and non-occupational source (e.g. smoking). Firefighter recognised both the importance of wearing PPE and the fact they are still not compliant in wearing it. They also perceived wearing PPE as burden and having only a limited stock of PPE. Education and training need to be reinforced to strengthen firefighters’ risk perception, hazard identification, and risk assessment of hazards exposure. Strict standard operating procedure (SOP) and supervision during firefighters’ task is crucial to reduce hazard exposure and increase PPE compliance. Systematic and thorough inventory management is needed to ensure adequate PPE supply. Post qualitative analysis, the firefighters’ perception on respiratory hazard exposure was obtained, demonstrating that the analysis is ready for further study.

Exploration of the Relationships between Hazard Perception and Eye Movement for Young Drivers

Aiming at young drivers’ hazard perception (HP) and eye movement, a cross-sectional study was conducted in the city of Xi’an, China. 46 participants were recruited, and 35 traffic scenes were used to test drivers’ hazard perception and eye movement. The difference analysis and correlation analysis were carried out for the acquired data. The results suggest that some indices of hazard perception and eye movement are significantly correlated. A higher saccade speed is in the direction of higher hazardous scenes. Higher complex scenes result in smaller saccade angle. The number of hazards unidentified is negatively influenced by complexity degree and hazardous degree of traffic scenes, and similar associations are found between hazard identification time, complexity degree, and hazardous degree. The hazard identification time and the number of hazards slowly identified are positively affected by the number of fixations and the number of saccades. Meanwhile, differences in the hazardous degree evaluation, hazard identification time, number of hazards unidentified, number of fixations, and number of saccades are found in different types of traffic scenes. The results help us to improve the design of road and vehicle devices, as well as the assessment and enhancement of young drivers’ hazard perception skills.

Job Safety Analysis and Hazard Identification of Welding Process in Semarang - JSA Method AS/NZS 4360:2004

Background: The welding workshop in Semarang City is spread over several areas in Semarang City. There are several types of work in welding workshops, namely, cutting raw materials, assembling, welding, grinding, sanding, and painting. This study aimed to analyze occupational safety and health risks in the informal welding workshop using the JSA (Job Safety Analysis) AS/NZS 4360:2004 Risk Management method. Method: This research was conducted using semi-quantitative method with descriptive analysis. A cross-sectional research design was used because data (observations, interviews, filling in risk analysis tables, work accidents, occupational diseases, and controls) were collected at a particular time. The study was conducted in Semarang, Central Java, and the population was all informal welding workshops. Result: This study showed that there are 8 types of welding tasks, 21 potential hazards, and 24 health consequences in a welding process. The total score calculated by multiplying "chance" by "severity" shows that 11 health consequences were acceptable risk while 13 others were high risk. Conclusion: The highest score of occupational health hazards was electric shock due to chipped cable, electric shock due to a chipped short circuit, and wet/rain/cloudy work area. Welders are recommended to follow the proper instruction in the welding process, and each workshop must provide a first aid box for its workers.

HAZARD IDENTIFICATION AND PROBABLISTIC SCENARIO SELECTION FOR SHIP- SHIP COLLISION ACCIDENTS

In collision risk-based design frameworks it is necessary to accurately define and select a set of credible scenarios to be used in the quantitative assessment and management of the collision risk between two ships. Prescriptive solutions and empirical knowledge are commonly used in current maritime industries, but are often insufficient for innovation because they can result in unfavourable design loads and may not address all circumstances of accidents involved. In this study, an innovative method using probabilistic approaches is proposed to identify relevant groups of ship-ship collision accident scenarios that collectively represent all possible scenarios. Ship-ship collision accidents and near-misses recently occurred worldwide are collated for the period of 21 years during 1991 to 2012. Collision scenarios are then described using a set of parameters that are treated individually as random variables and analysed by statistical methods to define the ranges and variability to formulate the probability density distribution for each scenario. As the consideration of all scenarios would not be practical, a sampling technique is applied to select a certain number of prospective collision scenarios. Applied examples for different types of vessels are presented to demonstrate the applicability of the method.

ANALISIS KESELAMATAN KESEHATAN KERJA (K3) TERHADAP RISIKO BAHAYA LINGKUNGAN FISIK DENGAN METODE “HIRARC” DI RUMAH POTONG HEWAN KOTA PEKANBARU TAHUN 2020

ABSTRAK Rumah Potong Hewan merupakan suatu bangunan yang memiliki desain dan konstruksi khusus digunakan sebagai tempat pemotongan hewan. Aktivitas kerja di RPH memiliki potensi bahaya yang dapat mengancam keselamatan dan kesehatan kerja. Berdasarkan observasi awal, RPH Kota Pekanbaru ini tidak memiliki laporan bulanan maupun tahunan mengenai data kecelakaan, dan juga belum pernah melakukan identifikasi, dan penilaian terhadap bahaya yang ada. Adapun tujuan penelitian ini yaitu untuk menganalisis keselamatan kesehatan kerja (K3) terhadap risiko bahaya lingkungan fisik di tempat kerja dengan metode “HIRARC” (Hazard Identification, Risk Assessment, and Risk Control). Jenis penelitian ini adalah kualitatif analitik. Lokasi penenlitian dilakukan di rumah potong hewan Kota Pekanbaru, penelitian dilakukan pada bulan Juli-Agustus 2020. Informan dalam penelitian ini sebanyak 6 orang, sebagai informan utama yaitu Kepala UPTD, 2 orang informan pendukung yaitu koordinator lapangan dan dokter hewan, dan informan kunci yaitu pekerja, metode yang digunakan peneliti yaitu wawancara mendalam dan observasi langsung. Berdasarkan hasil penelitian yang dilakukan potensi bahaya tingkatan risiko “Ekstrim” seperti diseruduk sapi pada proses penggiringan sapi menuju killing box, tertimpa katrol dan sapi pada proses penggantungan dan pemindahan sapi menggunakan katrol. Rumah Potong Hewan belum pernah melakukan identifikasi bahaya, penilaian risiko akan tetapi untuk pengendalian risiko sudah dilakukan beberapa upaya di rumah potong hewan, seperti SOP, Shift kerja, dan juga APD. Rekomendasi yang diberikan yaitu diharapkan sebaiknya RPH memiliki fasilitas yang berhubungan dengan kesehatan pekerja. Perlu adanya upaya pengendalian risiko secara engineering control, contohnya, membuat kerangkeng sapi. administrative control, seperti, memberikan sosialisasi, maintenance, housekeeping dan inspeksi, terhadap alat, mesin dan pekerja. ABSTRACTSlaughterhouse is a building having the design and construction specifically used as animal slaughterhouse. Slaughterhouse’s work activities have potential of hazards which can cause harm to workers’ safety and health. Based on pre observation, the slaughterhouse in Pekanbaru does not have any monthly and annual report about the data of accident. This livestock production also has no doing identification and assessment of hazard. The purposes of this study are to analyze occupational health and safety toward risk of danger physical environment at work, this study uses Hazard Identification, Risk Assessment, and Risk Control “HIRARC” method which using likelihood and severity level of each hazard as references to define a risk value. There are 6 informants the maininfromants is a UPTD head, 2 supporting informants are the field coordinator and venetarian, and the key informant is a worker, The methode that use in this study is interview And observation. The study shows that the most extreme are getting hit by a cow in cattle herding to killing box, falling of a cow hoist material from conveyor railing in shackling and hoisting process. Slaughterhouse has never done hazard identification and risk assessment. However, for risk control have done several attempts in slaughterhouse, such as Standard Operating Procedures, work shifts, and Personal Protective Equipment. Recommendation is given that the slaughterhouse should has facilities related to health of workers. It needs an effort to risk control through engineering control such as making cow cages, administrative control, such as giving socialization, maintenance, housekeeping and inspection of tools, machines and workersKeywords : Slaughterhouse, Hazard, Risk, Physical Environtmen, HIRARC.
