Abstract Introduction: Laboratories are not inseparable from the risk of work hazards. Laboratory workers are exposed to a high risk of occupational accidents and with contracting occupational diseases originating from specimens or human body fluids, such as blood and urine. The availability of PPE is very important and needed to protect laboratory staff from possible unwanted events. This study describes what factors are associated with the use of PPE in the laboratory. Methods: This research is an analytic study with a cross sectional study approach. 31 students from the Epidemiology Department of the Faculty of Health, Universitas Airlangga in 2018 were taken as respondents in this study. Data collection was done by using questionnaire method and interview with several students. The independent variables are knowledge, perceptions, compliance, motivation, attitudes, PPE regulations in the workplace, supervision, availability, and dissemination of PPE. Results: The results showed that there was a relationship between the use of PPE with several independent variables, which are, student perceptions, student compliance, student motivation, student attitudes, availability of PPE, and socialization of PPE. Several independent variables that have no relationship with the use of PPE are student knowledge, regulations on the use of PPE, and monitoring the use of PPE. Conclusion: Some independent variables that showed an association with the use of PPE included perceptions, compliance, motivation, attitudes, availability, and socialization of the use of PPE.

Introduction: Staircase is facilities functioned to connect floors. Stairs which are not ergonomic may cause fatigue and accident for the users. Universitas Airlangga Public Health Faculty Building is a three-story building. Each floor has 5 staircases on different sides. The aim of this study was to analyze the ergonomics aspects of the architectural design of the staircase. Method: This study used cross-sectional design with descriptive analysis. The measured dimensions of the staircase were riser's height, tread's depth, stairs width, stairs slope, landing, lighting level, handrail's height and diameter, and the presence of non-skid surface. The measurement tools were measuring tape, lux meter and cylinder bore gauge. Results: Measurement showed that all riser's height met the recommendation. Most tread's depth was below 30 cm. The width of Northwestern and Southwestern staircase was below the recommendation width, which was <125 cm. All slope of stairs was within the recommendation slope. The height and diameter of all handrails was 96 cm and 5.5 cm respectively and was above the recommendation. The lighting level during daytime on most staircase was above 100 lux but during nighttime was below 100 lux. There were landings that were wider than the stairs and non-skid surface at the edge of each tread. Conclusion: Most dimension of staircase (67.5%) in Universitas Airlangga Public Health Faculty Building met the design recommendation but the tread's depth, width of stairs, handrail's diameter and height, as well as the lighting on stairs need to be improved to make the stairs safer.
