HEARING PROTECTION

Employee exposure to excessive noise depends upon a number of factors, including:

  • The loudness of the noise is measured in decibels (dB).
  • The duration of each employee’s exposure to the noise.
  • Whether employees move between work areas with different noise levels.
  • Whether the noise is generated from one or multiple sources.

Person to Person Spread of Diseases

The person-to-person spread of infection may be:

  • Direct via droplet nuclei; sneezing, talking or coughing results in airborne particles being discharged from the nose, mouth or respiratory tract of the infected person onto the mucous membranes of another person
  • Indirect via articles or hands freshly soiled with the persons infectious secretions.

Lesson Summary

The following are the key points covered in the course:

  • Infection control is taking positive action to prevent and control infections.
  • It is essential to prevent infections from spreading.
  • The risk of infection is the likelihood that it may spread and cause harm.
  • Hand hygiene is the most essential way to prevent the spread of infection.
  • Personal protective equipment (PPE) can help protect healthcare workers from infection.
  • Environmental cleaning and disinfection help keep surfaces clean and free of germs.
  • Vaccination can help protect people from certain infections.
  • Many legislation and policies are in place to control infection, including the Bloodborne Pathogens Standard by the OSHA in 1991.
  • Risk management is crucial for preventing healthcare-associated infection.
  • Hazard assessment involves identifying potential hazards.
  • Personal Protective Equipment (PPE) is used to minimise exposure to hazards.
  • Training on the proper use of PPE is essential.
  • Different types of protective gloves and eye protection are available for specific hazards.
  • Hard hats are classified as Class A, B, and C for different levels of protection.
  • Foot and leg protection includes items like leggings and safety shoes.
  • Special-purpose shoes have safety-toe shoes and foundry shoes.
  • Body protection varies from disposable suits to fire-resistant cotton fabric that protects against cuts.
  • Hearing protection depends on factors like loudness, duration of exposure, and work area variation in noise levels.
