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