<br/><br/> Though these welding and grinding processes waste time and pose health and safety<br/>hazards, dust and debris generated by them contribute to the buildup in the workplace.<br/>Manual cleaning method is not time consuming, but at the same time it may not safe.<br/>Therefore, Portable Improvised Equipment Vacuum was developed in order to remove<br/>metal dust from the workplace, in which this would increase workplace cleanliness and<br/>safety. The suction motor, which has a maximum of 3200 rpm, is of wheel type and it has<br/>a storage passage for a 70-liter dual compartment carrying container against which a mesh<br/>wire filter is placed to isolate the debris. It also features a retractable 10-meter power cord<br/>for expanded mobility, a wheel cart with 360-degree caster wheels and brake lock, greater<br/>stability and other features. The prototype was tested to withstand, and the performance,<br/>functionality and stability of the prototype. The device was able to form the completed<br/>NHLO at an operational time of 6:45 to 7:10 minutes for filling the compartments to its<br/>maximum capacity. It was able to separate large debris, dust, clogged and read the weight<br/>accurately in the LED Indicator. The retractable power cord, the caster wheels for easy<br/>travel and flat positioning, the load sensor, and the buzzer were all fairly reliable at full<br/>capacity. Fifty respondents were evaluated on their relative functionality, durability,<br/>aesthetics, safety and economy using 4.5 overall mean rating, and evaluated the prototype<br/>as made by faculty, welding experts and students at the Technological University of the<br/>Philippines. The findings indicate that the prototype offers a new and effective means to<br/>industry cleaning that boosts productivity, alleviates health hazard and provides safer<br/>working place.<br/>Keywords: welding dust, metal debris, industrial vacuum, suction motor, debris<br/>segregation, LED indicator, load sensor, caster wheels, brake lock, retractable power cord.
