Finishing Concrete01:18

Finishing Concrete

Concrete finishing starts immediately after the concrete has been placed and consolidated. The initial step, screeding, involves leveling the concrete surface by removing excess material to flush it with the formwork's top. Following this, bull float or darby are employed to smooth the surface further, effectively lower high spots, fill low areas, and ensure larger aggregate particles are embedded within the concrete. This preparation is critical before the appearance of bleed water, as its...
Wood Surfacing01:14

Wood Surfacing

Wood surfacing is a critical finishing process designed to smoothen the wood surface, enhance its dimensional accuracy, and make handling safer. This process compensates for potential shrinkage during the seasoning phase by marginally increasing the wood dimensions before surfacing. It also helps correct some distortions that may occur as the wood dries.
The equipment used in the surfacing process is a plane equipped with rotating blades. This tool efficiently smoothens the wood surface and can...
Shotcrete01:18

Shotcrete

Shotcrete is a specialized technique where mortar or small aggregate concrete rich in cement content is sprayed onto a surface at high velocity. The force of impact compacts the material and enables it to cling to vertical or overhead areas without sagging. The technique involves layering the shotcrete in stages until it reaches approximately 4 inches in thickness. Operator skill in nozzle management is pivotal in deciding the quality of the shotcrete. Shotcrete is used in constructing tunnel...
Inhaled Medications01:23

Inhaled Medications

Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...
Dry Friction01:30

Dry Friction

Dry friction occurs between two solid surfaces in contact as they attempt to move relative to one another. In daily life, dry friction is encountered in various forms, such as when walking on the ground, sliding an object across a table, or rubbing hands together. Despite its ubiquity, the underlying mechanisms behind dry friction are not readily visible.
To illustrate this concept, imagine a wooden crate resting on a rough, non-uniform horizontal surface. When an external force is applied to...
Air-entraining Agents01:27

Air-entraining Agents

Air-entraining agents improve the durability and workability of concrete in climates with frequent freezing and thawing. These agents prevent cracks by introducing small air bubbles into the mix, creating spaces accommodating water expansion when temperatures drop. The air-entraining agents lower the surface tension of water, forming stable, small air bubbles. This method is more effective than having accidental large voids, as the intentional, smaller, and evenly distributed air voids improve...

Area of Science:

  • Occupational Health and Safety
  • Construction Management
  • Environmental Science

Background:

  • Drywall finishing generates significant dust, posing risks to worker health and productivity.
  • Effective dust control technologies are available but their adoption in the industry is not well understood.

Purpose of the Study:

  • To quantify the usage of dust control technologies in the drywall finishing industry.
  • To identify barriers to the adoption of these technologies.
  • To explore firm owner perceptions of dust-related risks.

Main Methods:

  • A telephone survey was administered to 264 owners of drywall finishing firms.
  • The survey included Likert-type and open-ended questions about technology usage, barriers, and risk perception.
  • Data were analyzed using descriptive statistics and content analysis, examining effects of firm size and union affiliation.

Main Results:

  • Respiratory protection was the most frequently used dust control technology.
  • Firm owners perceived dust risks to productivity and customer satisfaction as low-moderate.
  • Barriers to adopting more effective controls included usability, productivity concerns, cost, and misperceptions of risk.

Conclusions:

  • The drywall finishing industry shows variable adoption of dust control technologies.
  • Addressing identified barriers is crucial for improving dust control effectiveness.
  • Targeted interventions addressing usability, cost, and risk perception are needed to enhance worker health and safety.
