Pas­si­ve dust control

On-site dust cont­rol inclu­des acti­ve, pas­si­ve and reme­dial mea­su­res. All of the­se are nee­ded, but the focus should be on acti­ve dust cont­rol. Pas­si­ve dust cont­rol is nee­ded to reme­dy the shortco­mings of acti­ve dust control.

In pas­si­ve dust cont­rol, a con­struc­tion wor­ker is not an acti­ve par­tici­pant, but dust cont­rol works no mat­ter what indi­vi­dual wor­kers do. For example, pas­si­ve dust cont­rol may inclu­de site ven­ti­la­tion, com­part­men­ta­tion, nega­ti­ve pres­su­re units or gene­ral air puri­fying. Also mixing tent are pas­si­ve dust cont­rol.

With pas­si­ve dust cont­rol, wor­kers cont­rol the ‘airs­pace’ of the site. The most impor­tant thing is to keep dus­ty and dust-free work in sepa­ra­te spaces. Clean fil­te­red air from the out­si­de is brought into the con­struc­tion site, and it is direc­ted through clean spaces to dir­ty spaces. Final­ly, the air is fil­te­red out. This remo­ves fine dust from the air, which is not cap­tu­red by acti­ve dust cont­rol with the source ext­rac­tion devices. The flow of air at the con­struc­tion site is cont­rol­led so that dust can­not spread uncontrollably.

In pas­si­ve dust cont­rol, air can also be recycled indoors, whe­re­by the fil­ters of the air puri­fica­tion devices must be able to adhe­re to small par­ticles. Pas­si­ve dust cont­rol cor­rects human errors in the long-run, i.e. it acts as a back-up sys­tem for acti­ve dust control.

The role of acti­ve and pas­si­ve dust cont­rol mea­su­res in the proces­ses will inc­rea­se. Only in this way will we be able to gua­ran­tee a clean and healt­hy wor­king envi­ron­ment for con­struc­tion wor­kers in addi­tion to a clean comple­ted buil­ding. That is why it is worth inves­ting in acti­ve, but also pas­si­ve dust cont­rol, and reducing reme­dial action, i.e. less cleaning.
