Purpose
The purpose of the standard is to make sure that the hazards of chemicals are evaluated
That information concerning their hazards is communicated to employers and employees
![Page 3: HAZARDOUS COMMUNICATION SUBPART Z 1910.1200 2-hour Lesson Sam Mason, CMfgT, CSTM Authorized OSHA Trainer Morehead State University](https://reader034.vdocument.in/reader034/viewer/2022050819/56649f135503460f94c27516/html5/thumbnails/3.jpg)
More than 30 million workers are potentially exposed to one or more chemical hazards.
Estimated 650,000 existing hazardous chemical products, hundreds of new ones are being introduced
annually
This poses a serious problem for exposed workers and their employers.
Why????
![Page 4: HAZARDOUS COMMUNICATION SUBPART Z 1910.1200 2-hour Lesson Sam Mason, CMfgT, CSTM Authorized OSHA Trainer Morehead State University](https://reader034.vdocument.in/reader034/viewer/2022050819/56649f135503460f94c27516/html5/thumbnails/4.jpg)
Historically
Humans have found or made 50 million different chemicals here on Earth, the vast majority over the last few decades.
Number of unique chemicals now registered in a database maintained by the American Chemical Society as of yesterday.

New Rate
It took 33 years to get the first 10 million chemicals registered
A mere nine months to get the last 10 million chemicals into the database. acceleration is due to better tracking by the
American Chemical Society Alexis Madrigal

Who is covered
OSHA’s Hazard Communication (HazCom) standard applies to general industry, shipyard, marine terminals, longshoring, and construction employment and covers chemical manufacturers, importers, employers, and employees exposed to chemical hazards.
Horizontal
![Page 7: HAZARDOUS COMMUNICATION SUBPART Z 1910.1200 2-hour Lesson Sam Mason, CMfgT, CSTM Authorized OSHA Trainer Morehead State University](https://reader034.vdocument.in/reader034/viewer/2022050819/56649f135503460f94c27516/html5/thumbnails/7.jpg)
Background
The Hazard Communication Standard (HCS)
is based on a simple concept—
that employees have both a need and a right to
know the hazards and identities of the chemicals
they are exposed to when working
http://www.osha.gov/dsg/hazcom/standards.html
![Page 8: HAZARDOUS COMMUNICATION SUBPART Z 1910.1200 2-hour Lesson Sam Mason, CMfgT, CSTM Authorized OSHA Trainer Morehead State University](https://reader034.vdocument.in/reader034/viewer/2022050819/56649f135503460f94c27516/html5/thumbnails/8.jpg)
Background
The Hazard Communication Standard (HCS) will result in a reduction of illnesses and injuries
caused by chemicals.
Helps employers with having the information they need to design an appropriate protective program.
![Page 9: HAZARDOUS COMMUNICATION SUBPART Z 1910.1200 2-hour Lesson Sam Mason, CMfgT, CSTM Authorized OSHA Trainer Morehead State University](https://reader034.vdocument.in/reader034/viewer/2022050819/56649f135503460f94c27516/html5/thumbnails/9.jpg)
![Page 10: HAZARDOUS COMMUNICATION SUBPART Z 1910.1200 2-hour Lesson Sam Mason, CMfgT, CSTM Authorized OSHA Trainer Morehead State University](https://reader034.vdocument.in/reader034/viewer/2022050819/56649f135503460f94c27516/html5/thumbnails/10.jpg)
The HCS also allows: The need to know what protective measures are
available to prevent adverse effects from occurring
and provides employees with the information they need
MSDS
Background
![Page 11: HAZARDOUS COMMUNICATION SUBPART Z 1910.1200 2-hour Lesson Sam Mason, CMfgT, CSTM Authorized OSHA Trainer Morehead State University](https://reader034.vdocument.in/reader034/viewer/2022050819/56649f135503460f94c27516/html5/thumbnails/11.jpg)
Employees will be better able to participate in the programs effectively when they understand the hazards involved,
and to take steps to protect themselves.
Together (the employer and employee actions) will prevent the occurrence of adverse effects
caused by the use of chemicals in the workplace
Again…the Why??

Setting up a program
The HCS covers both:
Physical hazards (such as flammability), and
Health hazards (such as irritation, lung damage,
and cancer)
Most chemicals used in the workplace have some
hazard potential, and thus will be covered by the rule
![Page 68: HAZARDOUS COMMUNICATION SUBPART Z 1910.1200 2-hour Lesson Sam Mason, CMfgT, CSTM Authorized OSHA Trainer Morehead State University](https://reader034.vdocument.in/reader034/viewer/2022050819/56649f135503460f94c27516/html5/thumbnails/68.jpg)
One difference between this rule and many
others adopted by OSHA is that this one is
performance-oriented
That means that you have the flexibility to adapt
the rule to the needs of your workplace, rather
than having to follow specific, rigid requirements
Setting up a program
![Page 69: HAZARDOUS COMMUNICATION SUBPART Z 1910.1200 2-hour Lesson Sam Mason, CMfgT, CSTM Authorized OSHA Trainer Morehead State University](https://reader034.vdocument.in/reader034/viewer/2022050819/56649f135503460f94c27516/html5/thumbnails/69.jpg)
Make a list of all chemicals in the workplace that are potentially hazardous
The best way to prepare a comprehensive list is to survey the workplace
Identify chemicals in containers, including pipes
Establish purchasing procedures so that MSDSs are being received before a material is used in the workplace
Setting up a program
![Page 70: HAZARDOUS COMMUNICATION SUBPART Z 1910.1200 2-hour Lesson Sam Mason, CMfgT, CSTM Authorized OSHA Trainer Morehead State University](https://reader034.vdocument.in/reader034/viewer/2022050819/56649f135503460f94c27516/html5/thumbnails/70.jpg)
Identify hazardous chemicals in the workplace.
Compile a complete list of the potentially hazardous chemicals in the workplace
Determine if you have received material safety data sheets for all of them
If any are missing, contact your supplier and request one
You should not allow employees to use any chemicals for which you have not received an MSDS
![Page 71: HAZARDOUS COMMUNICATION SUBPART Z 1910.1200 2-hour Lesson Sam Mason, CMfgT, CSTM Authorized OSHA Trainer Morehead State University](https://reader034.vdocument.in/reader034/viewer/2022050819/56649f135503460f94c27516/html5/thumbnails/71.jpg)
Preparing and implementing a hazard communication program
All workplaces where employees are
exposed to hazardous chemicals must
have a written plan
The plan does not have to be lengthy
or complicated
![Page 72: HAZARDOUS COMMUNICATION SUBPART Z 1910.1200 2-hour Lesson Sam Mason, CMfgT, CSTM Authorized OSHA Trainer Morehead State University](https://reader034.vdocument.in/reader034/viewer/2022050819/56649f135503460f94c27516/html5/thumbnails/72.jpg)
Employee training
If there are only a few chemicals in the workplace, then you may want to discuss each one individually
Where there are large numbers of chemicals, or the chemicals change frequently, you will probably want to train generally based on the hazard categories (e.g., flammable liquids, corrosive materials,
carcinogens)
![Page 73: HAZARDOUS COMMUNICATION SUBPART Z 1910.1200 2-hour Lesson Sam Mason, CMfgT, CSTM Authorized OSHA Trainer Morehead State University](https://reader034.vdocument.in/reader034/viewer/2022050819/56649f135503460f94c27516/html5/thumbnails/73.jpg)
Documentation
The rule does not require employers to maintain records of employee training, but many employers choose to do so
This may help you monitor your own program to ensure that all employees are appropriately trained
