Gasoline is always available in the atmosphere whenever it is distributed, particularly at gas stations and depots. Excessive benzene exposure has been shown to affect bone marrow, leading to a reduction in circulating blood cells. This cross-sectional study aimed at determining the effects of petroleum on haematological and coagulation parameters among occupational workers. A total of 80 participants were recruited, 40 exposed (5 females, 35 males) and 40 controls (20 females, 20 males). A simple random sampling method was used, and a questionnaire was administered. Socio-demographic data of the study participants were taken. A full blood count was performed using a haematological analyser. Coagulation parameters were measured using the manual method at 37 °C. The results showed a statistically significant increase in the exposed group compared to the control group in Red Blood Cells (RBC) (5.77±0.78; 5.77±0.78), Haemoglobin (Hb) (13.27±1.48; 11.81±1.56), and Haematocrit (HCT) (41.89±5.19; 38.02±4.13), p<0.001, respectively. The Partial Thrombin Time and Kaolin (PTTK) results showed a statistically significant increase in the exposed compared to the control group (41.13±8.37; 30.28±5.61), p<0.001. The Prothrombin Time (PT) (13.03±0.28; 14.25±1.32) and International Normalised Ratio (INR) (1.002±0.02; 1.096±0.09) p<0.001 were statistically decreased between the exposed and the control group, respectively. There was a statistically significant negative correlation between PT, RBC (r= -0.295), PT, HCT (r= -0.310), and between INR, RBC (r= -0.301), INR, HCT (r= -0.315), p<0.05, respectively. This research showed a significant effect on the coagulation parameters. Hence, protective equipment for petrol station workers should be used to minimise exposure to gasoline.
