Objective. The study aimed to evaluate the sound pressure levels of selected traffic enforcer sites in the City of Manila. Methods. A Brüel & Kjær Integrating Sound Level Meter type 2225 was used to measure sound pressure levels in dB(A) to estimate personal noise exposure of traffic enforcers designated at Quezon Boulevard near Quiapo Church and Recto – Rizal Avenue on a weekday and a weekend. Graphs were generated while appropriate measures were calculated for the noise exposure levels. The mean exposure levels were compared with the Philippine Occupational Safety and Health standards by computing the corresponding permissible exposure limit for each work shift using the Equal Energy Principle.17 Results. Noise exposure levels at Quezon Boulevard ranged from 75.0 dB(A) to 91.5 dB(A) with mean noise exposure level of 84.3 ± 3.7 dB(A) and 82.5 ± 2.6 dB(A) for the weekday AM and PM shift, respectively. The mean noise exposure level at Quezon Boulevard for the weekend AM shift was 82.4 ± 2.6, whereas 80.4 ± 2.8 for the PM shift. The noise exposure levels at Recto – Rizal Avenue ranged from 81.5 dB(A) to 99.3 dB(A) with mean noise exposure level of 86.7 ± 2.6 dB(A) and 86.0 ± 2.1 dB(A) for the weekday AM and PM shift, respectively. The mean noise exposure level at Recto – Rizal Avenue for the weekend AM shift was 86.7 ± 2.3, whereas 89.0 ± 4.0 for the PM shift. Conclusion. The study showed that traffic enforcers designated at Quezon Boulevard and Recto – Rizal Avenue are exposed to noise levels that do not exceed the Philippine Occupational Safety and Health standards.

In accordance with the requirements of paragraph 3.2.6 of sanitary rules and norms «Sanitary and epidemiological requirements for physical factors at workplace», in the event of exceeding noise level at workplace above 80 dBA, an employer is obliged to assess the health risk of workers and confirm an acceptable risk to their health. The connection between the incidence of occupational and occupationally conditioned diseases with noise exposure exceeding the maximum permissible levels (80 dBA) was estimated. The assessment was carried out at a food industry enterprise of Perm Region. Assessing the relationship between morbidity and noise exposure is the first step in evaluation of occupational health risks for workers exposed to noise exceeding MAL. If a reliable relationship between morbidity and noise exposure is established, an assessment of occupational risk is conducted. The odds ratio (OR) for diseases characterized by high blood pressure and disorders of autonomic nervous system was <1 (confidence interval CI=0.11–1.61 and CI=0.08–2.78, respectively). The relative risk (RR) for diseases characterized by high blood pressure and disorders of autonomic nervous system was <1. The received data testify absence of connection of morbidity with exposure to industrial noise, calculation of etiological share of responses and levels of risk is not required.

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.

Noise measurement is essential for industrial usage. However, further attention to preventing noise pollution is needed, especially when working with equipment generating a high noise level, such as gas turbines. This study aims to determine the best way to perform noise measurement and analyze the octave band frequency generated by noise pollution caused by gas turbine equipment. Data from site measurements show that the gas turbines produce more than 85 dB of noise with a Z-weighted measurement. A noise measuring investigation was conducted to obtain the data for the 1/3 octave band. A frequency-domain was used to comprehend the properties of the noise measurement frequency band. The frequency band was classified into three different zones called low, medium, and high frequency, which is useful in noise measurement analysis to identify a viable solution to reduce the noise. On-site sampling was performed at the source, path, and receiver of three separate gas turbine locations within oil and gas operations. The 1/3 octave band data collection results at the sound source, path, and receiver demonstrate the noise level distribution at the perimeter of gas turbine installations in the low and medium frequency ranges. Most of the high noise frequency range is between 250 Hz and 2 kHz for source, path, and receiver. All acquired values are compared to the Department of Safety and Health (Occupational Safety and Health (Noise Exposure) Regulations 2019 in Malaysia. As a result, oil and gas service operators can monitor and take countermeasures to limit noise exposure at oil and gas facilities.

Insulation is a forgotten technology that can provide an unrivaled return on investment. The Citrus Industry is not an exception. Insulation is the ‘Rodney Dangerfield’ of the construction industry: It receives very little respect and is taken for granted. Insulation is a powerful resource when designed, applied, and maintained properly. Yet, this technology is often forgotten or put on the bottom of the list and ignored. A recent survey conducted by the National Insulation Association of more than 160 industrial plants, manufacturing, engineering, and architectural firms found that: • Most had no idea of the payback period, rate of return, with the use of insulation, nor a method to quantify costs versus savings • Many acknowledged that numerous areas of insulation were in serious need of repair • The majority did not understand that insulation had any real environmental “tie in” • Some did not consider additional insulation necessary: “the plant is working fine” • Many could not relate corrosion under insulation to having anything to do with the insulation • Most acknowledged their specifications were outdated • Many confirmed they did not have a dedicated job function to address insulation specifications or anyone who was the “insulation champion” • Many did not think of insulation as a system or requiring any special design review or technical consideration That survey confirmed the ‘Rodney Dangerfield’ characterization and formed the basis for the foundation of a major industry educational and awareness initiative. The benefits of insulation are in many cases invisible and long lasting. This technology is not some mysterious myth. Possibly it is misunderstood and under appreciated due to lack of knowledge. Calculating the operational benefits and the return on investment can be relatively simple. However, an insulation system does not have any moving parts, computer chips, or fancy gauges, and it is certainly not sexy. Maybe that is why in many circles insulation is not an exciting topic of discussion, even though it is a time tested and proven technology that can often provide an annual return on investment greater than 100%. There has not been a more important time in recent history than now to think about insulation differently. The Citrus Industry is not immune to that thought process.

Enclosed cabs with filtration systems, an engineering control preferred in the hierarchy of controls, may reduce heavy equipment operators’ silica exposure during demolition, grading, and excavation. We surveyed operating engineer trainers about silica training, familiarity with the Occupational Safety and Health Administration (OSHA) silica standard, and cab filtration systems. A voluntary and anonymous online survey was e-mailed to 437 trainers in January 2018. The response rate was 22.9 percent (n = 100). Most trainers (84 percent) covered health risks and silica exposure prevention in their courses. Of these, 59 percent discussed cab filtration as an engineering control. Trainers identified possible barriers to the use of cab filtration systems and a need for education to increase use, and raised concerns about other exposures associated with heavy equipment use. Education about selection, use, and maintenance of cab filtration systems to control silica exposure is needed. Engineering improvements to heavy equipment should address cab filtration, noise, heat, and vibration.

The affordable settlement is a problem that faced by several countries, especially on its urban including Jakarta. The rapid growth of people in Jakarta will increase the number of settlement need. The more demand of land for settlement, the higher the price of land will be. This paper aims to extract relevant information about urban settlement issues regarding the need of the affordable urban settlement in Jakarta and make a recommendation to solve it. We collected some data on urban issues which is based on the characteristics of urban settlement in Jakarta. In this case, not all people can afford to have proper settlement. Only those who could afford will have a good house. The government built ‘rusun’ towers to provide an appropriate settlement for lower income families. However, there are many issues that must be addressed in order to make towers as a sustainable settlement. The issues that relevant to be discussed is whether the ‘rusun’ unit has a comfortable space for household, for social interaction between the inhabitants, for safety and health standards. ‘Rusun’ is one solution of settlement for the poor in Jakarta from Government. By applying an integrated affordable urban settlement in Jakarta and adapted to the existing inhabitants needs, we are optimistic that the need of affordable settlement for the poor can be resolved.
