What are the two main types of respiratory protection?

Respirator (filtering device) – uses filters to remove contaminants in the workplace air , there are two main types: Non-powered respirators – rely on the wearer’s breathing to draw air through the filter. Powered respirators – use a motor to pass air through the filter to give a supply of clean air to the wearer.

Airborne precautions apply to patients known or suspected to be infected with microorganisms transmitted by airborne droplet nuclei. Preventing airborne transmission requires personal respiratory protection and special ventilation and air handling.

Which statement is true about respiratory protection?

The correct answer is: Respiratory protection is important for first responders because inhalation is the most significant route of entry for hazardous materials. Which type of PPE is designed to shield or isolate a responder from chemical or biological hazards?

Does OSHA require a respiratory protection program?

The OSHA respiratory standard requires contractors to develop and implement a written respiratory protection program for situations in which PELs of airborne contaminants could be exceeded or when the employer requires use of respirators by workers.

How often does OSHA require respirator testing?

You must be fit tested before you use a respirator in the workplace, and you must be retested at least every 12 months to make sure that the respirator you use still fits you. You must be fit tested with the specific make, model, style, and size of respirator that you will be using.

What are the four types of respirators?

There are four common classes of APR facepieces: • disposable; • quarter mask; • half-mask; and • full-face. Disposable respirators (dust masks) provide protection against nuisance dusts and particulates.

What type of PPE is a respirator?

Respirators include dust masks, chemical cartridge respirators, PAPR (powered air purifying respirators), airlines, and SCBA (self-contained breathing apparatus). Respirators do not include staff use of surgical masks for patient or product protection.

Transmission-Based Precautions. There are three categories of Transmission-Based Precautions: Contact Precautions, Droplet Precautions, and Airborne Precautions.

What disease requires contact precautions?

Illnesses requiring contact precautions may include, but are not limited to: presence of stool incontinence (may include patients with norovirus, rotavirus, or Clostridium difficile), draining wounds, uncontrolled secretions, pressure ulcers, presence of generalized rash, or presence of ostomy tubes and/or bags …

What type of respirator is a SCBA?

Combination Respirators can be either a supplied-air/ SCBA respirator or supplied-air/air-purifying respirator. The SCBA type has a self-contained air supply if primary airline fails and can be used in IDLH environments.

What is the safest respirator?

An N95 respirator is a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles.

Is a dust mask considered a respirator?

Dust masks are not NIOSH* approved disposable filtering facepieces. They can be worn for comfort against non-toxic nuisance dusts during activities like mowing, gardening, sweeping and dusting. These masks are not respirators and do not offer protection against hazardous dusts, gases or vapors.

What is a 3M respirator?

Our NIOSH-approved respirators come in a variety of styles and are designed to help protect against various hazard types, providing the level respiratory protection you need. 3M respirators are available as reusable, disposable, powered air, supplied air, self-contained breathing apparatus or emergency escape.

How do you measure a respirator?

Most respirators come in three sizes: small, medium, and large. The size of the mask is determined by the size of the rubber seal. The rubber seal should fit over the person’s entire face, including their nose, mouth, and eyes. The larger the person’s face, the large the rubber seal needs to be.

How many types of BA sets are there?

There are 3 main types of Breathing Apparatus – Escape, Self-Contained and Airline.

What is respiratory isolation?

Respiratory isolation is used for diseases that are spread through particles that are exhaled. Those having contact with or exposure to such a patient are required to wear a mask.

What are the 10 standard precautions?

  • Patient assessment for infection risk.
  • Hand hygiene.
  • Respiratory and cough hygiene.
  • Personal protective equipment (PPE)
  • Safe management of equipment.
  • Safe management of environment.
  • Safe management of blood and body fluids.
  • Safe management of linen.

What are the 5 modes of transmission?

Modes of transmission

  • Direct. Direct contact. Droplet spread.
  • Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)

What are the 4 types of disease transmission?

The modes (means) of transmission are: Contact (direct and/or indirect), Droplet, Airborne, Vector and Common Vehicle.

What are the diseases transmitted by air?

  • Anthrax.
  • Aspergillosis.
  • Blastomycosis.

What are the 4 items of PPE droplet precautions?

Droplet precautions means wearing a face mask (also called a surgical mask) when in a room with a person with a respiratory infection. These precautions are used in addition to standard precautions, which includes use of a face shield or goggles as well as gown and gloves if contact with blood/body fluids is possible.

What means respirator?
