The employer shall provide a respirator that is adequate to protect the health of the employee and ensure compliance with all other OSHA statutory and regulatory requirements, under routine and reasonably foreseeable emergency situations.
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.
Who needs a respiratory protection program?
OSHA requires employers to develop and implement a written respiratory protection program for situations in which permissible exposure limits (PELs) of airborne contaminants are exceeded, or when the employer requires the use of respirators by employees.

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?
The 10 Standard Infection Control Precautions (SICP)
- Patient assessment for infection risk.
- Hand hygiene.
- Respiratory and cough hygiene.
- Personal protective equipment (PPE)
- Safe management of equipment.

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?
Some of the common pathogens that may spread via airborne transmission are:
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?
Definition of respirator
1 : a mask or device worn over the mouth and nose to protect the respiratory system by filtering out dangerous substances (such as dusts, fumes, or bacteria) from inhaled air.
What is difference between N95 and respirator?
Surgical N95 respirators and standard N95 respirators are similar in appearance and both can effectively filter airborne biological particles such as viruses and bacteria when properly selected and worn. 1,2,3,4 The key difference between a standard N95 respirator and a surgical N95 respirator is fluid resistance.
