<![CDATA[High noise levels, as well as insufficient or excessive lighting and extreme room temperatures, can have an impact on employee Occupational Health and Safety (OHS). In testing service companies, employee complaints regarding physical work environment conditions—such as noise from laboratory equipment, overly bright lighting, and excessively cold room temperatures—indicate potential risks to occupational health and safety. This study aims to analyze the influence of physical environmental factors in the workplace. A descriptive analysis method was used to interpret primary and secondary data, which were then compared with Threshold Limit Values (TLVs), and followed by improvement recommendations using fishbone analysis. Measurement data showed the highest noise level in the analyst room at 83.1 dBA, close to the TLV of 85 dBA. The highest lighting levels were found in the BITU division head’s room and at Hilman’s desk, at 556 LUX and 576 LUX respectively. The lowest lighting level was recorded at Denrio’s desk with 301 LUX, compared to the lower TLVs of 150 LUX and 500 LUX. Room temperature measurements across all sampled locations showed a maximum of 27.3°C and a minimum of 21.2°C. Recommendations from this study include the development of Standard Operating Procedures (SOPs) for impact mitigation, employee training or education, and facility improvements to reduce the negative effects on occupational health and safety.
