Airborne Particulates: Dealing With Construction Dust

Workers in today’s construction sites are at risk of health problems due to their exposure to large amounts of airborne dust produced by a wide range of particulate matter during construction. Metalworking, welding, abrasive blasting, laser and plasma cutting, mixing, and grinding all use dry materials that emit minute dust particles into the air, where they float freely or settle on surfaces. The presence of airborne dust in an industrial setting can be a major issue if it is not dealt with effectively. For this reason, construction businesses need BossTek dust suppression systems to keep workers safe from breathing in harmful dust particles in the air.

How to get rid of airborne dust

To clean the air, a dust suppression system is put in place to separate airborne particles from the air. Here are some ways you can stop particles from getting into the air.

Self-contained weld booths

A common problem with welding equipment is the excessive amounts of smoke and dust it produces. Industrial facilities need to invest in portable, self-contained welding booths with downdraft capability to divert welding smoke away from workers’ faces and out of the building. Welding booths are designed to trap as many airborne particles as possible to keep workers safe.

Dust collectors

Dust collectors are units that take in contaminated air from manufacturing operations and release clean air. Effective dust collectors protect workers from dry particles and pollutants. Cartridge dust collectors and baghouse designs are only two of the many types of dust collectors available today.

Reverse baghouses

The dust that has built up inside a reverse air baghouse can be easily removed by pumping clean air through the system in the opposite direction. This causes the bag to collapse and empty its contents into a hopper below. Whenever a pulse jet baghouse needs cleaning, high-pressure blasts of air are directed into the top of the bag to temporarily halt the flow of soiled air. The dust cake is released as the cloth in the baghouse expands in response to the air blast. The compressed air blast needs to be substantial enough to send a shock wave down the length of the bag, cracking the dust layer.

Cartridge collectors

Cartridge collectors are very effective because they use either horizontal or vertical filters. Even in high-production settings, the improved Down-Flow technology used by vertically placed filters that pulse from the bottom keeps the air clean. Vertical filter cartridges pulse dust more effectively than horizontal ones, preventing the uneven dust loading that can occur with the latter. Cartridge collectors employ perforated metal cartridges with a pleated, nonwoven filtering medium. Cartridge collectors come in single-use and continuous-duty models. When a single-use collector is turned off, the cartridges can be swapped out and the dust cleared without disrupting the collection process. The continuous-duty design uses a regular pulse-jet cleaning technique to keep the cartridges clean.

Potable dust collectors

Dust can be a nuisance on construction sites, but portable dust collectors make life easier. They are suitable for grinding stones, dry dust, and welding fumes. The majority of them have a movable extraction arm that delivers better filtration.

In the end, the best way to keep workers from being exposed to dust particles at work is to make sure there is enough ventilation. Quality air filtration systems ensure that the worksites are free of potentially hazardous particles, including dust, smoke, and oil mist. Workers benefit from breathing in clean air, which in turn helps protect their health.
