“…We observed that the light-engineering maintenance personnel at times work with insuffi cient illumination, which is also a risk-factor of WMSDs. 41 They use torch lights or draw power from the vehicle engine while working in dark or night-time. This provision is insuffi cient while they work with circuits which are situated deeper in huge equipment.…”

Background: Modern defence system has a significant role of electrical, electronic and instrument technicians in armed forces. Despite their intensive role, little is known about work-related musculoskeletal disorder in these technicians. Objective: To investigate the prevalence of the work-related musculoskeletal disorder in defence personnel involved in electrical and electronic maintenance and repairs. Methods: A cross-sectional study was carried out for 3 years, in Electrical, telecom and instrument defence technicians (N = 164). Prevalence of work-related musculoskeletal disorder was assessed using the Nordic Musculoskeletal Questionnaire. Effect of age, working hours, work experience, Basal metabolic index and type of job on the prevalence of work-related musculoskeletal disorder was investigated using logistic regression analysis. Results: A total of 119 (72.56%) respondents reported work-related musculoskeletal disorder with 53.04% multiples & 19.51% single work-related musculoskeletal disorder. Simultaneous presence of neck, shoulder and upper back work-related musculoskeletal disorder were observed. Highest rate of work-related musculoskeletal disorder was in neck (44.44%), followed by shoulder (27.16%), ankle/ foot (14.81%), elbow/ forearm (12.96%), low back (11.72%) and wrist/ finger (9.87%). Neck (44%) related work-related musculoskeletal disorder were highest across all job crafts. Work experience (p = 0.012; OR = 0.87; 95% CI – 0.78- 0.97), working hours (p = 0.031; OR= 1.73, 95% CI – 0.58-5.12) smoking (p = 0.00 ; OR = 5.3, 95 % CI = 4.3 – 8.48) and job crafts like electrician (p = 0.434; OR = 1.89, 95% CI = 1.08-3.31) and telecom mechanics (p = 0.026; OR = 1.26, 95% CI =0.74 – 2.15) were significantly associated as risk factors of work-related musculoskeletal disorder. Conclusion: High prevalence of work-related musculoskeletal disorder was observed in electrical, telecommunication & instrument mechanics, with higher multiple work-related musculoskeletal disorder. Working hours, work experience, job craft and smoking were highly associated with a work-related musculoskeletal disorder. We suggest suitable ergonomic intervention and awareness program along with smoking control drive to reduce the risk of work-related musculoskeletal disorder.

“…Finally, the operators stated that improved lighting on and around their equipment may help with improving safety during ingress and egress. In the recent decade, lighting has been a major focus of mine safety research as a means to prevent STF and struck-by accidents (Sammarco et al, 2012;Yenchek and Sammarco, 2010). However, much of this research has been focused on improving lighting for underground mines and replacing standard incandescent lighting with light-emitting diodes to improve the amount of light, improve visual performance, reduce glare, reduce power consumption, and reduce required maintenance (Sammarco et al, 2009).…”

A large proportion of non-fatal slips, trips, and falls (STFs) at surface mining facilities are associated with mobile equipment. Ingress and egress from mobile equipment can pose a fall risk to mobile equipment operators. The objective of this study was to determine mobile equipment operators' views of STF risks from mobile equipment, and to ascertain what factors, tasks, and conditions they perceive as contributing to these risks. A thematic analysis of 23 individual interviews and 2 group interviews was conducted, with 10 overarching themes identified from the transcripts. Mobile equipment operators indicated that being unable to see their feet or the ladder rungs during descent and the presence of contaminants on the ladders caused by normal operation make egress more dangerous than ingress. The flexible rails and high heights of the lower rungs identified over 40 years ago as issues for mobile equipment operators still pose a perceived STF risk. Further, the requirements of routine maintenance tasks such as oil and filter changes, greasing, and cleaning windows pose fall risks due to inadequate access and the need to carry supplies up and down equipment ladders. In addition to the mobile equipment, hazardous ground conditions and insufficient lighting were found to be key issues around the mobile equipment and in parking areas. The findings of this work indicate that mobile equipment operators feel at risk for STFs due to the design and condition of their equipment, and would like to see ladders replaced with safer stairways as the primary ingress/egress system.

“…Compared with other wireless signals [ 10 , 11 , 12 ], visible light has the advantages of green safety [ 13 , 14 ], less multi-path effect [ 15 ], no electromagnetic effect [ 16 , 17 , 18 ] and strong resistance to electromagnetic interference [ 19 , 20 , 21 ]. The crucial thing is that the lighting equipment already present in the mine brings great convenience to our equipment deployment [ 22 , 23 , 24 ]. Nowadays, there are many innovative research papers and excellent results that apply visible light technologies, including visible light communications (VLC) technology and visible light positioning (VLP) technology to the underground mine environment, benefiting from the above-mentioned advantages of visible light.…”

A Novel Mine Cage Safety Monitoring Algorithm Utilizing Visible Light

The mine cage has an important role in the production of coal mines. It has many safety problems in the transportation of people, such as overloading of personnel and illegal outreach of human limbs. However, the harsh mine environment makes it very difficult to monitor personnel overload and limb extension. To solve these two problems, we propose a novel safety monitoring algorithm of the mine cage based on visible light. With visible light technology, our algorithm cleverly utilizes the existing underground lighting equipment (i.e., miner’s headlamp and the miner’s lamp deployed on the mine cage) as the transmitter to broadcast the light beacons representing unique identity information through visible light frequency modulation. Next, cheap photodiodes deployed in the mine cage are used as the receiver to perceive the modulated optical signals. Then we use the frequency matching method for personnel counting and the frequency power comparison method for illegal limb extension monitoring. Moreover, a novel method of monitoring the delineated safe area of the mine cage is also proposed to ensure that all the miners are in the delineated safe area. Finally, we conducted extensive experiments with a simulated mine cage model. Results show that our algorithm has superior performance. With the photodiode SD5421-002, the accuracy of personnel overload judgment and safe area monitoring of our algorithm can reach 99%, and the accuracy of limb extension monitoring is more than 96%.
