Survey Safety01:28

Survey Safety

24
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Design Consideration01:22

Design Consideration

172
Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.
The factor of safety is another key...

Standard Precaution

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Obedience01:08

Obedience

32.6K
According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation,...

The Availability Heuristic01:08

The Availability Heuristic

5.9K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Design of Prismatic Beams for Bending

193
The design of prismatic beams, structural elements with a uniform cross-section, focuses on ensuring safety and structural integrity under load. The design process begins by determining the allowable stress, either from material properties tables, or by dividing the material's ultimate strength by a safety factor. This safety factor is essential for accommodating uncertainties, and varies depending on the material—timber, steel, or concrete—with each having unique strength and...

Area of Science:

  • Agricultural Safety and Health
  • Occupational Health and Safety
  • Grain Science

Background:

  • Out-of-condition grain is a primary cause of grain entrapment and engulfment.
  • Grain quality significantly influences the risk of grain dust explosions.
  • Limited research exists on how specific grain conditions affect worker safety in grain handling.

Purpose of the Study:

  • To establish an advisory panel of experts to examine grain condition's relation to worker safety risks.
  • To gain further understanding of safety issues in grain handling.
  • To guide educational and dissemination efforts regarding grain safety.

Main Methods:

  • A purposeful sampling technique was used to recruit grain handling and storage experts.
  • Semi-structured interviews were conducted with the advisory panel.
  • Thematic analysis using NVivo 14 identified key themes related to grain safety.

Main Results:

  • Four main themes emerged: challenges to worker safety, communication needs, grain quality indicators impacting safety, and mitigation strategies.
  • Out-of-condition grain was confirmed as a primary causal factor in entrapments and engulfments.
  • The panel noted a lack of in-depth knowledge on protective grain quality traits.

Conclusions:

  • Grain condition is a critical factor in preventing grain entrapment, engulfment, and dust explosions.
  • Improved understanding and communication regarding grain quality indicators are essential for worker safety.
  • Further research into specific grain quality traits that enhance safety is warranted.
