Presentation Transcript
goals
Goals
  • Recognize respiratory health risks when working in Agricultural Mechanics.
  • Know when and how to wear protective respiratory equipment.
effects of air contaminants the respiratory system
Effects of Air Contaminants the Respiratory System
  • Gases and chemical can cause irritation of the cells lining the airways within the lungs. One of the body's basic responses to protect against this is to produce mucus. This mucus can make the airway opening smaller making it more difficult to breathe.
effects of air contaminants the respiratory system1
Effects of Air Contaminants the Respiratory System
  • Acute exposure:
    • Acute exposure to air contaminants such as welding fumes can result in eye, nose, and throat irritation, fever, chills, headache, nausea, shortness of breath, muscle pain, and a metallic taste in the mouth.
  • Chronic exposure:
    • Chronic exposure can result in respiratory effects including coughing, wheezing, and decreased pulmonary function.
when to wear a respirator
When to Wear a Respirator
  • Who needs respiratory protection? Those who:
    • work in dusty fields and buildings
    • handle moldy hay
    • work in silos
    • feed or work with feedstuffs
    • work in corn silage
    • uncap silos
    • clean grain bins
    • work in areas where bird droppings or dust from animal hair, feathers, or fur are present
    • work with fish meal
    • apply agricultural chemicals ((e.g. fertilizers, pesticides, fumigants)
    • work with toxic paints or solvents
    • work in areas where dust containing old paint, rust and wood particles
when to wear a respirator1
When to Wear a Respirator
  • Two respirator categories:
    • 1) air purifying respirators (APR)
    • 2) supplied air respirators (SAR)

When to Wear a Respirator and the Correct Type

In case the respirator cannot or will not be used a simple mask should be used. The respirator is more efficient at removing the particles but a mask will still help.

how to do a fit test on a respirator
How to do a Fit Test on a Respirator
  • A fit test is a test of how well a respirator fits on an individual.
  • OSHA requires employers to properly fit test their respirators to those who will use them.
how to do a fit test on a respirator1
How to do a Fit Test on a Respirator
  • A series of test exercises are completed while trying to determine if any contaminated air leaks through the respirator.
  • This is done by having the test subject try to smell or taste a saccharin (sweetener) solution that is sprayed around them when they are wearing their respirator.

How to do a Fit Test on a Respirator
  • The test subject shall indicate to the test conductor if at any time they taste the saccharin. If the test subject does not report tasting the saccharin, the test is passed.

How to do a Fit Test on a Respirator
  • Fit testing should not be confused with a respirator fit check.
  • A fit check the method you use to ensure that the respirator you are using does not have an air leak.

How to do a Fit Test on a Respirator
  • Positive fit check
    • exhale while covering the exhalation valve with the palm of your hand – if you feel air against the skin of your face, there is a leak in the seal.
  • Negative fit check
    • cover the cartridge(s) with your hands and inhale –if the mask is drawn tightly to your face, there is no leakage.
