Occupational Vat Dyeing Practices in the Kano Metropolis of Nigeria Part 5: Chemical Exposure, Potential Hazard, and Safety Practices

Abdullahi S.^*, Abdussalam, R. M, Umar, H. A

Since the 1930s synthetic dyes and chemicals are being used in Nigeria where occupational dyers in Kano metropolis followed suit. Exposure to these chemicals may likely endanger the dyers depending on safety practices performed on the job and health effects may be exerted directly at the site of application (affecting workers) and/or later in the l...

Fabrication and Characterization of Flambouyant Seed Particles-filled Unsaturated Polyester Composites

Umar, H. A^*, Ishiaku S. U., Mohammed K. Yakubu, Kogo A. A.

The research aimed at fabrication and characterization of Flambouyant Seed Particles (FSP) filled unsaturated polyester (UP) composites. The composites fabrication was achieved via hand layup with particle size of 100 µm at different filler loading of 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 and 22 wt %. The composites were characterized by tensile prope...
