Identifying Airborne
Health Hazards
Depending on the type of
products that you manufacture, you and your employees can encounter a variety
of airborne hazards. Most of us know that we should wear some type of air respirator in many of our work environments. What can be difficult is identifying the particular hazards and determining what protective equipment.
Here are some of those hazards that are commonly encountered in many shops:

Here are some of those hazards that are commonly encountered in many shops:
Dust
from Power Equipment. If your employees use power equipment, such
as an angle grinder, router or jig saw, they can generate a cloud of dust. Long-term
exposure to dust from sawing and sanding wood can cause a range of health
issues, including allergic respiratory reactions and lung cancer.

Welding
Fumes. Welding not only generates particulates but can give off
harmful fumes which can lead to a variety of ailments, including cancer.

Fumes. Breathing solvent fumes from airbrushing and spray
painting not only can make you dizzy but what’s worse is that protracted
exposure can result in liver damage.

Breathing
Problems. The most severe breathing problems, such as COPD, may not
surface until many years after a worker has been subjected to the hazard. (It
may interest you to learn that one of the major causes of COPD for those who
have never smoked is occupational exposure to dust and chemicals.) While
medical treatments have improved for some patients experiencing chronic
respiratory disease, these are the type of problems that will usually last your
lifetime.

If you are exposed to
airborne health hazards, you should wear an air respirator. Some of the most
popular types are air purifying respirators, which filter contaminants from the
air. Other types of respirators provide the wearer with fresh air. Three types
of air purifying respirators are dust masks, half mask respirators and full
face respirators.

Developing
a Respiratory Protection Program
In light of the potential
risks to your employees, you may require your employees to wear an air
respirator on the job. If you do, OSHA demands that you establish a respiratory
protection program for your shop. Other federal and state agencies have issued
very specific regulations covering the selection, use and maintenance of the
appropriate air respirator for the work that your employees are performing.

If you run a shop and
require that employees wear an air respirator, OSHA demands that you follow a
number of procedures. Many of their regulations are common sense. The OSHA
Respiratory Protection Standard includes the following requirements:

Step
One: Develop a Program. Establish a written respiratory
protection program. You should update your written program as conditions change
in your shop. These conditions could include the use of new materials, such as
solvents or adhesive removers, the addition of new equipment or the
introduction of new manufacturing processes.

Step
Two: Assign an Program Administrator. Assign management of
your program to a qualified employee trained in respiratory hazards. While this
does not mean that you personally need to conduct the training sessions, as a
shop owner you just need to provide the training. To aid training, OSHA has
developed several training videos, which you can use.

Step
Three: Identify the Hazards. Airborne hazards will vary
from one type of shop to another. Your responsibility is to identify and
evaluate the hazards in your shop. When using raw materials, such as paints or
solvents, you should read the manufacturer’s Safety Data Sheets (SDS) and
product labels to learn about any health hazards associated with product use.
In some cases, these SDS bulletins may include air respirator recommendations.
You can also call the manufacturer, when you have questions.

Step
Four: Select Appropriate Respirators. After identifying
any hazards related to specific applications, you need to select the
appropriate respirators and filter cartridges for your employees. As an
employer, you will also need to establish a schedule for changing cartridges.

Step
Six: Maintain Respirators. To work properly, you and
your employees must maintain your respirators according to the manufacturer’s
product bulletins. Maintenance procedures, which should be explained in your
written respiratory protection program, should cover inspection, cleaning and
storage of equipment.

Over time, filter cartridges
will become clogged with contaminants. When this happens, breathing through the
respirator mask will become difficult. This is a sure sign that you should
change the filter cartridge. Another clue that a filter cartridge is not
working is when you can smell or taste a vapor or when you become nauseous or
dizzy. Irritation of your nose or throat also indicates that you should change
the cartridge.

Eight: Conduct Worksite Specific Training. In
directing employees, it usually is a good practice to explain what jobs need to
be done that day and what personal protection equipment is required to do that
job. Then it is up to you, if you are the supervisor, to make sure that your
employees follow the safety guidelines. When they don’t follow the rules, then
you need to take corrective action.

employees follow the safety guidelines. When they don’t follow the rules, then
you need to take corrective action.
Step
Nine: Fit Testing. Provide employee to be fit tested with
any tight fitting respirator selected for their use. This is important, because
if the mask does not fit tightly contaminants can leak past the seal. A number
of factors can affect how well a respirator mask fits on your face. The most
obvious variable is the shape of the wearer’s face. If one type of mask does not fit an employee
properly, you need to find one that does work. Other factors can compromise a
tight seal including facial hair, piercings, scars, glasses and jewelry. Fitting,
which includes qualitative and quantitative (measurable) testing, should ensure
a proper fit.

When you perform fit
testing, you must conduct the test under the exact conditions in which the mask
will be worn. That means that you must conduct the test using the same make and
model that your employee will use. What’s more, if your employee wears glasses
or jewelry, you must conduct the test as he or she is wearing these items. Employees must be retested every 12 months.
NOTE: The loose fitting type of respirator, such as a respirator hood or helmet,
does not need to be fit tested.

Step
Ten: Annual Medical Evaluation. Air-purifying respirators,
which utilize filtering cartridges or canisters, can make breathing more
difficult. This added stress creates an increased risk for any employee dealing
with an existing health issue, such as heart problems. For this reason, if you
require an employee to wear a respirator, OSHA regulations oblige you to provide
him or her with an annual medical evaluation.

The simplest type of air purifying respirator is a
disposable cloth dust mask that fits over your mouth and nose. A
NIOSH-certified N95 respirator is acceptable for many applications. These masks
are only designed for one use and should be discarded at the end of a work
shift. A much better choice is to wear either a half mask respirator or full
face mask with a particulate filter, which provide a better seal so there is a
lower risk of contaminant leakage.

Filter Cartridges for Particulates
There are two different types of filters. One type
filters solid particles. The other type is a chemical cartridge, which filters
gases. Cartridges are labeled and color-coded for easy identification. Some
cartridges can be stacked one on top of another to filter multiple types of
contaminants.

If you purchase a reusable face mask, a wide variety of
filter cartridges are available. You must use the appropriate cartridge for
specific applications, such as grinding, welding or spray painting. Cartridges

There are different types of particulate filters. The
National Institute of Occupational Safety and Health (NIOSH) has developed a
rating system for particulate filters. This rating is comprised of a number and
a letter. The number indicates how much of particulates the cartridge or dust
mask filters. The number 95 means that the cartridge filters 95% of the
particulates in the air. 100 indicates that virtually 100% of the particulates
are filtered. The letter in front of the number tells you what type of
particulate is filtered. N means non-oil proof. R indicates that the filter is
oil resistant up to 8 hours. P is for oil proof past 8 hours.

Organic Vapor Filter Cartridges
For airbrushing or spray painting with some paints, you
will need to buy an organic vapor (OV) cartridge. These cartridges include a
layer of activated carbon, which absorb certain organic paint and solvent
vapors. The OV cartridge should be used in conjunction with a particulate
filter.

OV cartridges with a carbon filter have a limited life.
This life expectancy varies on several factors, such as relative temperature
and humidity, breathing rate, type of chemical vapor and the concentration of
the chemical vapor. For example, ambient
humidity above 85% can cut the service life of an OV cartridge in half. One rule of thumb is if you can smell a vapor
while wearing your mask, it is time to change the cartridge. Typically an OV
cartridge will last 30 to 40 hours or 30 days, whichever comes first.

As a word of caution, if you are spraying urethane paint,
carbon filters will not protect you from the dangerous isocyanates in the
paint. For this type of paint, you need a different type of respirator. Instead
of filtering contaminated air, these respirator supply the wearer with clean air.
