【 摘 要 】

Forty saw dust samples from four mature hard wood plants grown insouthwestern part of Nigeria were analyzed for their ash contents, moisture contents, metalliccontents and hence the fire extinguishing strength of the saw dust ash by classical andinstrumental methods of analyses. Mahogany ( Khaya ivorensis ) wood saw dust ash had thehighest mean metallic content (5.989±2.51ppm) followed by Opepe ( Sarcocephalus latifolius ), 4.704±0.21ppm while Poro poro (Sorghum bicolour) wood ash had the least metallic content (1.611±0.48ppm). Mahogany also had the highest mean moisture content (2.6615±0.64) whileOpepe had the least moisture content (0.9362±0.45). The fire extinguishing strength ofMahogany was the highest, and had a positive correlation with its metallic content as depictedby their correlation coefficient (0.850). Poro poro had the least fire extinguishing strength. Thecomparison of the extinguishing strength of wood saw dust samples and the commonly usedABC fire extinguisher showed that ABC fire extinguisher has more extinguishing strength thanthe wood saw dust ash. Hence, improvement on the extinguishing strength of the saw dust ashis necessary.
