Small-scale industries account for a large proportion of jobs and play a vital role in most countries’ economic growth and prosperity. Due to the very low use of personal protective equipment (PPEs), employees are exposed to numerous physical, chemical, and accidental hazards in small-scale industries. PPEs are very effective in minimizing occupational injuries, accidents, and other hazards which otherwise result in substantial manpower and financial losses. The study objective was to assess the availability and use of PPEs as well as self-reported occupational exposures among workers in surveyed small industries in Jeddah. The study involved 102 workers from 28 small-scale industries (vehicle repair, welding, and paint). A survey was conducted to gather data of socio-demographic characteristics, self-reported occupational exposures, and frequency of PPEs used by workers. The occupational exposures (never exposed, sometimes exposed and always exposed) were reported in percentages including; noise exposure (19.6, 73.5 and 6.9%); dust/smoke exposure (9.8, 69.6 and 20.6%); vapors/fumes exposure (11.8, 60.8 and 27.5%); and direct sunlight (43.1, 56.9 and 0%), respectively. The reported use of different PPEs in descending order was; knee joints mats (50%), welding shields (50%), safety glasses (33.3%), gloves (27.5%), face masks (26.5%), safety shoes (10.8%) and earplugs/ muffs (8.8%). On the basis of this study findings, hand hygiene and general OSH awareness like interventions can be developed which will help in minimizing workplace exposures among small-scale industry workers.
In Saudi Arabia, the construction industry has been growing remarkably during the past several years. However, the most hazardous worksites in the country may be found in this industry. This study identified the causes of accidents and injuries in the construction industry among 300 workers in Jeddah City, situated on the coast of the Red Sea. Results from the questionnaire showed that the major cause of accidents and injuries is the lack of awareness about occupational safety and lack of experience among the workers (>82%); and the most common type of accidents and injuries that occur in the construction industry, are workers falling from a height (>80%), and electrical shock (>60%). Recommendations to prevent accidents and injuries in this industry are provided in this paper.
Welding is a major industrial process used for joining metals. Occupational exposure to welding fumes is a serious occupational health problem all over the world. The degree of risk to welder’s health from fumes depends on composition, concentration, and the length of exposure. The aim of this study was to investigate workers’ welding fume exposure levels in some industries in Jeddah, Saudi Arabia. In each factory, the air in the breathing zone within 0.5 m from welders was sampled during 8-hour shifts. Total particulates, manganese, copper, and molybdenum concentrations of welding fumes were determined. Mean values of eight-hour average particulate concentrations measured during welding at the welders breathing zone were 6.3 mg/m3 (Factory 1), 5.3 mg/m3 (Factory 2), 11.3 mg/m3 (Factory 3), 6.8 mg/m3 (Factory 4), 4.7 mg/m3 (Factory 5), and 3.0 mg/m3 (Factory 6). Mean values of airborne manganese, copper, and molybdenum levels measured during welding were in the range of 0.010 mg/m3–0.477 mg/m3, 0.001 mg/m3–0.080 mg/m3 and 0.001 mg/m3–0.058 mg/m3 respectively. Mean values of calculated equivalent exposure values were: 1.50 (Factory 1), 1.56 (Factory 2), 5.14 (Factory 3), 2.21 (Factory 4), 2.89 (Factory 5), and 1.20 (Factory 6). The welders in factories 1, 2, 3, and 4 were exposed to welding fume concentration above the SASO limit value, which may increase the risk of respiratory health problems.
A lot of attention has been paid to improving occupational safety and health (OSH) in small scale industries all over the globe. This study describes the outcomes of a preliminary OSH status assessment in small scale industries of motor vehicle repair workshops (MVRW) in Jeddah, Kingdom of Saudi Arabia (KSA). An inspection tool composed of 10 OSH elements and 62 items employed walk-through survey, observations and interviews. The mean positive responses for different OSH elements surveyed were as follows; personal protective equipment (PPEs) (43%), emergency preparedness (49%), fire protection (60%), facilities (80%), general workshop safety (43%), housekeeping (17%), chemical exposure (12%), services and maintenance (57%), mechanical handling (81%) and tool safety (63%). However, special concerns were found for OSH elements including; use of PPE's, emergency preparedness, general workshops safety, housekeeping and exposures to chemicals as having safety score less than 50%. OSH elements with lower positive responses at surveyed workshops would be addressed through further monitoring and training of technical and administrative staff. This preliminary survey will form the basis of a more comprehensive study for evaluation of an accurate representative OSH status in small scale industries in KSA.
In this study, an Al2O3/graphene oxide/halloysite nanotube (Al2O3/GO/HNT) nanocomposite has been synthesized and used as an adsorbent for the sequestration of cationic methylene blue (MB) and anionic congo red (CR) dyes from wastewater.
