A systems approach is developed for defining compliance with the noise criteria of the Occupational Safety and Health Act of 1970. The result is a flow diagram which can be used as a “road map” for determining progress toward compliance. A flow diagram is also developed as a guideline for evaluating the feasibility of engineering noise control. General suggestions are made for controlling the noise produced by air sources, oscillating bodies, frictional sources, impact, and gears. Absorption, enclosures, and barriers have also been considered as means of interrupting the path between the source and the receiver. Noise exposure has been included as an important factor with economic feasibility as a final consideration in the flow diagram.

Physical damage from acoustic energy is not a new phenomenon. The first recorded event is in Biblical history when Joshua lead seven priests around Jericho seven times blowing trumpets and the people shouted and the walls fell. Ancient mortar and gun battery crews put cotton in their ears to lessen the sound, and this was a type of noise control. Since World War II much concern has been exhibited about hearing loss due to high noise levels in work environments, In order to limit the hearing loss of the average person, the Occupational Safety and Health Act of 1970 specifies the noise exposure of an employee for an eight-hour day shall not exceed 90 dBA. This has resulted in a massive noise control effort in industry. Paper published with permission.

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.

Drill Holes

Noise-induced hearing loss (NIHL) is the second most prevalent illness in the mining industry. According to a study conducted by the National Institute for Occupational Safety and Health (NIOSH), in which over 42,000 audiograms from metal/nonmetal miners were analyzed, approximately 70% of miners have hearing impairment as compared to 9% of non-occupationally noise-exposed workers. One of the machines used extensively in metal/nonmetal mines responsible for high noise exposure levels of its operators is the jumbo drill, used to drill holes at the mines for blasting purposes. In this context, NIOSH is conducting research to develop engineering noise controls for jumbo drills that would reduce the prevalence of hearing loss among operators of this equipment. The first step of the noise control development process consists of identifying and ranking dominant noise sources present during operation of the jumbo drill. To this end, a noise study was conducted at NIOSH’s laboratories in which a microphone phased array system was used to identify dominant noise sources, and the transfer path analysis method was used to rank these sources based on their contribution to the operator location. Results showed that the drill string and the drilling mechanism — known as the drifter — are the dominant sound-radiating components in the operation of the jumbo drill.

Industry Needs

In Indonesia, industrial nurses are only required to have an Occupational Safety and Health (K3) certificate up to this time. This policy is not in line with Law No. 36/2014. As a result, there is an imbalance between industry needs for quality nursing services and existing nurses' competence. This study aimed to analyze policies related to the competencies of corporate nurses in meeting the needs of health care services in the industry. This study used PRISMA Flow Diagram as a systematic review supported by quantitative descriptive design. The research was conducted through document searches, identifying keywords, and reviewing articles from Google Scholar (6 records), Research Gate (8 records), and PubMed (5 records), and others were 52 records. Out of 71 documents, 36 records were assessed for eligibility, and 35 records were excluded, and 16 studies were included in the review. It was found that there was an imbalance between the regulations, education programs, and implementation. It requires the strengthening of a multisectoral approach in the development of OH nursing education.

The aim of this chapter was to explore a sociotechnical systems approach applying a novel taxonomy with respect to safety performance. The study applied a combination of qualitative and quantitative methodologies. Workers (n = 120) and managers (n = 85) were asked to complete a questionnaire survey (Appendix). The following hypotheses were supported: “Activities of the management” had positive impacts on five aggregated variables, namely “near-accident investigation and instructions” (H1), “occupational safety and health (OSH) training” (H2), “operations, technical processes, and the safe use of chemicals” (H3), “use of personal protective equipment” (H4), and “measuring, follow-up, and prevention of major accidents” (H5). By undertaking a statistical evaluation and then devising a novel taxonomy, it was possible to gain detailed insights into diverse aspects of a high-risk industry's work with regard to complex sociotechnical systems. When applying the current approach through participatory cooperation, organizations may acquire new perspectives on their safety performance.

Among underground coal miners, hearing loss remains one of the most common occupational illnesses. In response, the National Institute for Occupational Safety and Health (NIOSH) conducts research to reduce the noise emission of various underground coal mining equipment, an example of which is a roof bolting machine (RBM). After the removal of coal or rock, the remaining strata may be subject to fall, either from overhead (the roof) or from the side (the rib). One method used in underground coal-mines to prevent failures requires the installation of roof bolts. The roof bolting machine operator trams the machine to the required location, drills a hole into the strata, and then installs a roof bolt, supporting the roof or the rib, as the case may be. Field studies support the premise that, on average, drilling noise is the loudest noise that a roof bolting machine operator would be exposed to and contributes significantly to the operators’ noise exposure. NIOSH has determined that the drill steel radiates a significant amount of noise during drilling. NIOSH is developing bit and chuck isolators to reduce vibration, and thus noise radiation of the drill steel, with the longer-term goal of reducing roof bolting machine operator noise exposure. Laboratory testing has shown that operator ear sound pressure levels may be reduced by 3 to 7 dB(A), depending upon the test configuration and drilling media.

The National Institute for Occupational Safety and Health (NIOSH) Pittsburgh Mining Research Division (PMRD) conducts a wide variety of mining-related health and safety research. As part of this research, PMRD’s Workplace Health Branch maintains a Noise Control Team tasked with developing noise controls to reduce future incidences of noise-induced hearing loss (NIHL) among the nation’s mining workforce. A noise control project that PMRD is currently investigating is the development of noise controls to reduce the noise emissions from jumbo drills. Operators of jumbo drills are frequently overexposed to noise, putting them at risk of NIHL. A key contributor to the noise at the operator location is the noise radiated from the jumbo drill string, or drill rod. Jumbo drilling is rotary-percussive in nature, and the drill string is mechanically excited by the cutting of the media as well as by a percussive hammer. These excitations travel from the bit/rock interface and from the drifter hammer into the drill string, vibrating the structure and causing it to radiate noise. The development of an instrumented drill string will allow NIOSH to quantify the forces within the drill string during drilling, providing critical information for the development of jumbo drill noise controls.
