under the hazard communication standard are now changing

including changes in the Material Safety Data Sheets

labels and warning requirements

OSHA's hazard communication standard

known as hazcom will now integrate

into the United Nations globally harmonized system of classification and

labelling

of chemicals

it will now be known as the hazard communication

any globally harmonized system

or simply the GHS

the purpose of this videos to review the major changes that you're going to see

the GHS or

globally Harmonized System will now require chemical manufacturers to

provide specific criteria

to address health and physical hazards as well as classification of chemical

mixtures

labels will be required to show much more information than before

for example chemical manufacturers and importers must provide a lable that

includes

a signal word a pictogram a hazard statement and precautionary statement for

each

hazard class and category

what we now know as material safety data sheets

are now going to be shortened in name and will be known

simply as safety data sheets or SDS

instead of MSDS

Safety Data Sheets or SDS

will now have a new format

that has 16 specific sections

ensuring consistency in presentation

of important protection information OSHA's hazard communication standard is

designed to ensure that information about chemical hazards

and associated protective measures are disseminated to all workers

this standard has been revised to include the GHS

the major changes you should know right now are hazard classification

this replaces hazard determination hazard classification provides specific criteria

for classification of health and physical hazards

as well as classification of mixtures labels

chemical manufacturers and importers will be required to provide a label

that includes a harmonized signal word pictogram

and hazard statement for each hazard class and category

Safety Data Sheets will now have a specified

16 section format in the new GHS

all chemicals will now be classified into three major hazard groupings

the first and the largest is physical hazards

this includes items like explosives

flammable gases and aerosols flammable solids

gases under pressure self reactive substances that can react violently with

water

and other solid substances that emit a flammable gas when wet

oxidizers like oxygen and hydrogen peroxide

and corrosives which are either strong acids strong bases

or concentrated solutions of certain weak acids or weak bases

they can exist as any state of matter including liquids

solids gases mists or vapors

the next major has a group is health hazards examples of health hazards

include acute toxicity

for example hydrogen cyanide is a highly toxic substance

acute exposure at relatively low doses can result in death

skin corrosions or irritants can cause severe skin burns

and/or eye damage another health hazard is serious

eye damage or eye irritation, then respiratory or skin sensitization

sensitizers can cause severe organ damage or major permanent

functional changes in organ systems, for example the lungs

Germ Cell Mutagenicity. These are chemicals which may cause mutations in

the germ cells of humans

and then these mutations can be transmitted to offspring.

Carcinogens. These are chemicals associated with causing cancers.

Other toxic chemicals that affect the reproductive organs or other specific

organs

and aspiration hazards. The third major hazard grouping is environmental hazards

this is new and OSHA does not have jurisdiction over environmentally toxic

chemicals

the labeling and SDS requirements under GHS

require environmental labeling but OSHA considers this portion of the

standard

non-mandatory as environmental hazards are regulated by the EPA

therefore we will not be concerned with this area it is being mentioned here for

information purposes only.

Let's talk about the Material Safety Data Sheet

or as we know it now the old MSDS. The old MSDS have been found to be less

useful

in many circumstances because it did not contain enough information

the new safety data sheets or SDS will replace the nine part

MSDS with a 16 part document although that

sounds more complicated you'll find that much more information

is being presented in a much better way. The SDS

is product related and although it is not able to provide information that is

specific for any given workplace where the product may be used

the expanded SDS information will include much more data

funneled down into a better document to help us understand the chemicals we are

using

the SDS will enable people to develop an active program of worker protection

measures

including training that is specific to your individual workplace

and to consider any measures that may be necessary to protect the environment.

Information in an SDS also provides a source of information

for other workers such as those involved with the transport of dangerous goods

emergency responders, poison centers,

and finally, consumers. The new standardized SDS format will make

finding hazard and chemical information on the SDS

easier for both employers and employees.

There's no set format to the Material Safety Data Sheet and they can range in

length from one page to 20 or more pages

the new Safety Data Sheet will contain

only 16 headings all SDS will be in the standard format

which will make it easier for all of us to find the information

that we need for our workplace. The SDS headings

sequence and content are similar to many of the items required

by other regulatory organizations. Reviewing the headings give you an idea

of how comprehensive the information will be.

In the new standardized format Safety Data Sheets

the first thing that will be provided is an identification of the product or

chemical.

Next, the hazards within the product will be identified

and the composition or other information will be provided

about ingredients.First aid measures will be discussed as well as fire

fighting measures

and that will be followed by a section that discusses how to handle

accidental releases. Handling and storage is the next category,

and then the eighth category will discuss exposure control

or your personal protection what kind of PPE may be needed when

handling the product. Physical and chemical properties will be explained

followed by the stability and reactivity information and then toxicological

information.

The next three sections ecological information, disposal considerations,

and transport information are not required by OSHA,

but may be included in the safety data sheet, and the last two sections will be

regulatory information and then any other information deemed pertinent

by the manufacturer or an outside regulatory agency.

Here the first two pages of a sample Safety Data Sheet. Note the specific

sections.

All safety data sheets will have the sections or headings in this order and

in this format.

This will make finding specific information much easier.

There is not a standard format for the GHS label.

However, there are required label elements.

The GHS label elements that you see here with an asterisk

have been standardized and are directly related to the hazard level.

The other label elements are defined based on common definitions.

But these three elements, hazard pictograms, signal words, and hazard

statements

are all hazard warnings and are required to be grouped together

on the label. The symbols, signal words, and hazard statements have all been

assigned

to specific hazard categories and classes.

On labels, the GHS system uses only two words:

Danger and Warning are used to inform the chemical user of the severity of the

hazards in the chemical.

The use of just two signal words is used to help simplify warnings

and the labeling system. For example, thinking about the word danger

imagine yourself driving up to an intersection with a stop sign

the signals to the driver that this is a potentially dangerous intersection

and that the driver is required to stop and look before proceeding through the

intersection.

If the signal word on a label is danger, the chemical user should understand that this

is a highly hazardous chemical

and they should stop and become familiar with all the characteristics of the

product before proceeding.

On the other hand, if the label contains the word warning

this is like driving up to an intersection controlled by a yield sign.

The driver can proceed through the intersection with caution as it also has

the potential to be a hazardous intersection.

However, labels that contain the signal word "Warning" indicates that the severity

of hazards of the chemicals

are less than those chemicals classified with the signal word

"Danger." Hazard statements are supposed to give the chemical user additional

information

about the hazard that is depicted in the pictogram. For example,

if you saw the flame pictogram on a label for a flammable liquid

the hazard statement might be "keep away from fire, sparks

and heated services. as stated earlier hazard statements have been standardized

and the chemical manufacturer,

importer, or distributor is responsible for using the appropriate hazard statement or

statements

on the label. The other statements shown are more examples

of standardized hazard statements. Pictograms

are now required. Only eight are required by OSHA,

but a ninth may also be used to indicate environmental hazards.

The labels for hazardous chemicals must contain

one or more of the pictograms to illustrate the hazards of the chemical.

The exclamation mark pictogram, when shown by itself on a label,

is for chemicals that have toxicity levels that are harmful to humans but

are not usually fatal.

This includes chemicals that could be irritants to skin and eyes.

For example, pepper spray is a skin and eye irritant, and many soaps, detergents and

cleaning products like ammonia

and chlorine can be irritants. The exclamation mark pictogram will also be

used to show skin sensitizers,

acute toxicity, narcotic effects, respiratory tract

irritants. Also something that could be hazardous to the ozone layer.

However, this would not be mandatory under OSHA. While the chemical hazards

associated with the exclamation mark pictogram are a concern

and precautions need to be taken they are not as dangerous as the health effects

or hazards associated with the health hazard pictogram.

Health hazard means a chemical that can cause acute or chronic health effects

in exposed personnel. Chemicals like gasoline

benzene, acetone, and products like brake cleaner or anything containing volatile

organic compounds.

will have a health hazard pictogram on the label. When you see the health hazard

pictogram,

the product or chemical will fall under the list of potential health hazards

including the group mentioned earlier. The flame pictogram

indicates the product or chemical has flammable or self-reactive

characteristics

or other hazards as listed here.

This is the pictogram for all gases under pressure.

Don't be fooled by the picture of the cylinder because it covers much more.

This symbol includes all cylinders, propane tanks,

natural gas tanks, refrigerated liquids, and many other products in this category.

The chemical hazards associated with the corrosion pictogram

are skin corrosives and can cause permanent eye and skin damage.

This symbol, one that is seen commonly in the military, is one we don't see very

often in private industry,

unless of course you handle ammunition, explosives and so on.

Oxidizers are symbolized by an "O" with flames on top of the "O".

The skull and crossbones pictogram is for chemicals with acute toxicity effects

that are deadly and could lead to fatality if not handled correctly.

The dead fish and tree symbol signals environmental information.

This is non-mandatory under the OSHA standard as OSHA

does not regulate environmental hazards. As we said before the EPA regulates

environmental hazards

and the chemical manufacturer importer distributor would be required to comply

with EPA regulations

in addition to the OSHA labeling requirements. Here's an example

of the labels you may see under the new GHS rules.

As stated earlier in this presentation there is no standard format required for

the GHS label,

so the information may or may not be in the order presented here.

In fact you can anticipate that most labels will look different from each

other.

The thing you need to keep in mind is that even though labels will look
