Dust Control – Soil Stabilization – Erosion Control

There are different types of construction dust that is created at the workplace. The type of construction and location of the site will determine what is in the air.

The dryer regions of the country have a problem with particle matter floating in the air whose make up is different than wetter regions where the nuisance dust could be from the saw dust that the building tools create. The cleaning up of the loose debris is the solution for most dust problems that are actually created on the construction site that is directly caused by the construction process. The health hazards of construction site dust could include cement residue, asbestos, mineral fibers with a man made origin and the most common is wood dust.

The reason for the concern is the effects it has on the people working at the site and the surrounding region. When natural sources of dust from plants and animals combine with the airborne particles of the construction site, it could adversely affect the membranes of the occupance.

The US Department of Health and Human Service’s National Institute for Occupational Safety and Health consider silicosis has a major problem and cause of health problems that has its origins from construction dust . Construction dust control from the particle matter smaller the 10 micrometers or PM10 has to be approached from a different perspective than those that are naturally occurring in our environment

The airborne crystalline silica that originates from the concrete, masonry and rock on the site can become lodged in the membranes and lungs of the respiratory systems of the people on and near the site. Once there, they become hardened and cause permanent damage and even death.

Construction dust control for this problem can be accomplished when the proper precautions are taken along with the right equipment. The blades that are used to cut concrete and other masonry items should be equipped with a water attachment to make the dust to heavy to become airborne. When drilling into rock the same accessory should be used to weigh down the dust and prevent it from becoming airborne.

Cleanup afterwards is just as important. The water that was used to weigh down the dust particles will evaporate over time. Collection and proper disposal is a necessary part of keeping the work site as free as possible of nuisance dust.

Another little thought about source of silica is from the abrasive materials that are used on the construction site. This includes the silica paper and sanding discs that are used to prepare and condition the different surfaces around the site. When these materials are used, the operator should be using a dust mask on themselves to prevent inhalation of the particle matter.

The US Government classifies nuisance dust that is created by the landscape as a natural event under the air pollution laws. This is a contributor to the construction dust problem but not the whole cause. With the proper precautions control of construction dust can minimize the adverse effects in the people on and near the construction site.

The occupational overexposure to coal mine dust by coal miners continues to occur despite legally enforceable limits, U.S. health officials say.

Deaths occurring among younger persons from coal workers’ pneumoconiosis declined substantially from 1968-2006, the Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report released Wednesday says. Coal workers’ pneumoconiosis is the accumulation of coal dust in the lungs and the tissue’s reaction to its presence.

However, annual years of potential life before age 65 of coal workers’ pneumoconiosis have been increasing since 2002, and mean years of potential life before age 65 per decedent has been increasing since the early 1990s — meaning that workers die at younger age — the study by the National Institute for Occupational Safety and Health finds.

The NIOSH study recommends hazard surveillance, workplace-specific interventions and strengthening of current coal workers’ pneumoconiosis prevention and elimination efforts to protect workers’ health.

Federal officials unveiled a three-pronged strategy to combat black lung disease during a meeting Thursday at the National Mine Health and Safety Academy in Beaver.

Mining officials and medical experts say education, stricter enforcement and new regulations can curb the disease, which has been on the rise in the region and has killed some 10,000 miners in the last decade.

Thursday’s meeting was the first of four informational sessions planned by Mine Safety and Health Administration.

“There is a collective agreement that we have to fix this problem,” MSHA Director Joseph Main told a packed room that included representatives from mining companies, the United Mine Workers of America and former miners suffering from the ailment.
