healthcare settings.

In certain situations, healthcare workers may need to

be protected from airborne hazards, such as infectious

agents or hazardous chemicals in their workplace.

Respirators are a type of personal protective equipment,

or PPE, that can protect you from breathing in such hazards.

After viewing this video, you should

have a basic understanding of why respirators are used

in the healthcare industry, and how to properly use them.

You should also understand that a standard

issued by OSHA - the Occupational Safety and Health

Administration - or by an OSHA-approved State plan,

requires your employer to have a comprehensive

respiratory protection program whenever respirators

must be used.

In addition, this video will discuss some

common myths about respirators that you may hear in

your workplace.

It is required that you understand how to use a

respirator, and understand the major components of a

respiratory protection program.

This video may be a part of your respiratory protection training,

but it’s not a substitute for the more in-depth, worksite-specific

training that your employer is required to provide.

While this video discusses your employer’s

responsibilities under OSHA’s respiratory protection

standard, remember that the purpose of a respirator is

to protect your health and safety.

So let’s begin:

Airborne hazards may be solid particles - like dusts -

droplets - like mists -

or gases.

When such hazards are present in your workplace, your

employer must control them in several ways, including

engineering controls, work practice controls, and

administrative controls.

When workers cannot be adequately protected from

respiratory hazards through engineering, work practice,

and administrative controls, employers must provide,

and workers must use, personal protective equipment,

also known as PPE.

Respirators are a type of PPE used to protect workers

against breathing airborne hazards and they are often

used with other types of PPE such as gloves, goggles,

and procedure gowns.

In this presentation, one of our goals is to set the record

straight about the proper use of respirators in

healthcare settings.

So during this video we will take a look at some of the

misconceptions, or myths that you may encounter in

your workplace.

Myth: Respirators are only necessary for tuberculosis –

or TB - exposures.

Actually there are a number of situations in healthcare

settings where workers may need to wear a respirator

to protect against airborne hazards – TB is only one of them.

There are two primary types of respiratory hazards in

healthcare settings – airborne infectious agents and

gaseous chemical exposures.

Let’s take a look at these two types of hazards, the ways

workers might be exposed to them and how they can be

protected from them.

First let’s look at airborne infectious agents.

Probably the most common use of respirators in

healthcare settings is to protect workers against

airborne infectious agents that cause diseases such as

tuberculosis, SARS, pandemic influenza, chicken pox, and measles.

Healthcare workers are exposed to these

hazards during the care of patients suspected or

confirmed to have airborne transmissible diseases.

Workers might also be exposed when they enter a

negative pressure airborne infection isolation room – or AIIR;

when they are present during aerosol-generating medical

or laboratory procedures or during

autopsies on suspected or confirmed infectious individuals;

when they transport infectious patients in an enclosed vehicle;

and when they function as first receivers of

victims from a biological agent attack.

Patient care isn’t the only situation where respiratory

protection may be needed to protect workers against

airborne transmission.

For example, laboratory personnel working with

highly infectious agents may need respiratory protection.

Also, engineering and maintenance staff may be

exposed during tasks such as replacing filters in an

isolation room or a laboratory hood ventilation system.

Now let’s talk about gaseous chemical exposures.

Workers in healthcare settings may also need to use

respirators to protect against airborne chemical

exposures from substances such as pharmaceuticals

during dose preparation, sterilants, like glutaraldehyde,

and fixatives like formaldehyde.

It’s very important to understand that the respirators

used to protect against infectious agents may be

inappropriate to protect against chemical hazards.

We will discuss respirator selection in more detail later

in the program.

When a respirator is required by your employer, your

employer must develop and implement a

comprehensive respiratory protection program.

This program must meet the requirements of either Federal

or State OSHA’s Respiratory Protection Standard.

Employers must comply with the standard, and you

need to have a basic understanding of their responsibilities.

Your employer must:

identify and evaluate hazards;

develop a written program;

properly select respirators;

evaluate respirator use;

correct any problems with respirator use;

conduct medical evaluations and fit testing;

provide for the maintenance, storage and cleaning of respirators;

provide training;

and provide you with access to specific

records and documents, such as a written copy of your

employer’s respiratory protection program.

Because each workplace is different, your employer’s

respiratory protection program must be tailored to your

specific workplace.

For example, workplaces will differ

in types of respiratory hazards, designated personnel,

policies, procedures, and methods of compliance.

These differences must be reflected in the employer’s program.

Your employer’s respiratory protection program must

be managed by a properly trained program administrator.

Their job is to monitor the implementation of the

program and to make sure that workers are properly protected.

Myth: Surgical masks provide the same protection as respirators.

Respirators and surgical masks are two types of

personal protective equipment - or PPE - that are

used to protect workers in healthcare settings.

A surgical mask is not a respirator, and that’s an

important distinction for you and your employer to

understand, so let’s review the significant differences

between a respirator and a surgical mask.

What is a respirator? A respirator is a type of personal

protective equipment designed to reduce your

exposure to airborne contaminants.

Respirators are available in different types and sizes,

and the respirator you use must be individually selected

to fit your face and to provide a tight seal.

A proper seal between your face and the respirator

forces inhaled air to be pulled

through the respirator’s filter material, and not through

gaps between your face and the respirator.

If your supervisor requires you to use a respirator, it

must be NIOSH-certified and must be used in the

context of a comprehensive respiratory protection

program, according to OSHA’s Respiratory Protection

standard, twenty nine CFR nineteen ten point one thirty

four, which includes but is not limited to medical

evaluation, fit testing, and training elements.

Respirators are used routinely to protect healthcare

workers against airborne infectious diseases, such as

tuberculosis, anthrax, SARs, and Hantavirus because

they protect against both large and small particles.

What is a Facemask? A facemask is a loose-fitting,

disposable mask that covers your nose and mouth.

Surgical masks, dental masks, medical procedure masks,

isolation masks and laser masks are all types of facemasks.

Facemasks help stop large droplets from being spread

by the person wearing them, whether that person is a

patient or a healthcare worker.

Facemasks also keep splashes or sprays from reaching the

mouth and nose of the person wearing them.

However, facemasks are not designed or certified

to seal tightly against your face or

to prevent the inhalation of small airborne contaminants.

During inhalation, small airborne contaminants pass

through gaps between the face and the facemask and

the material of the mask.

Remember, facemasks are not considered respirators

and they do not provide respiratory protection.
