Personal Protective Equipment01:20

Personal Protective Equipment

Personal protective equipment (PPE) is unique clothing or equipment worn by an employee to minimize or prevent exposure to infectious agents. PPE creates a barrier between the employee and the infectious materials. PPE must be readily available in the patient care area. PPE includes gloves, gowns and aprons, masks and respirators, goggles, face shields, shoes, and headcovers:
Hearing01:31

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
Community Based Intervention01:30

Community Based Intervention

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.
Foundations of Community Mental Health Programs
Central to the success of community-based interventions is the...
PPE Use in Healthcare Settings II: Doffing01:10

PPE Use in Healthcare Settings II: Doffing

The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.
PPE Use in Healthcare Settings I: Donning01:22

PPE Use in Healthcare Settings I: Donning

Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...

Summary

Implementing noise level indicators alongside training significantly boosts hearing protection device (HPD) use in construction workers, reducing noise-induced hearing loss risk.

Area of Science:

  • Occupational Health
  • Audiology
  • Industrial Hygiene

Background:

  • Hearing protection devices (HPDs) are crucial for preventing noise-induced hearing loss (NIHL).
  • Limited effectiveness of HPDs is often due to inconsistent usage among high-risk populations like construction workers.
  • Intervention strategies are needed to improve HPD compliance in noisy work environments.

Purpose of the Study:

  • To evaluate the impact of a multi-faceted intervention on HPD usage in construction workers.
  • To compare the effectiveness of training alone versus training combined with personal noise level indicators (NLIs).
  • To identify factors influencing HPD compliance in the construction industry.

Main Methods:

  • A three-pronged intervention was implemented: baseline training, toolbox (TB) reinforcement, and personal noise level indicators (NLIs).
  • 176 construction workers across eight sites participated in the study with pre- and post-intervention assessments.
  • HPD usage rates were tracked and compared between intervention groups.

Main Results:

  • Overall HPD use increased by 12.1% post-intervention and 7.5% two months later.
  • The group receiving both TB and NLI interventions showed the greatest increase in HPD use (approx. 25% from baseline).
  • Workers using TB and NLI were twice as likely to use HPDs compared to those receiving only baseline training.

Conclusions:

  • Standard HPD training has a modest effect on increasing device usage.
  • Personal noise level indicators, when combined with training, significantly enhance HPD compliance in construction settings.
  • Further research is needed to optimize the use of NLIs for maximum impact on hearing protection.
