MSDS is a document that contains information on the potential health effects of exposure to chemicals, or other potentially dangerous substances, and on safe working procedures when handling chemical products

1. MSDS-MATERIAL SAFETY DATA SHEET
or SAFETY DATA SHEET

2. • A Material Safety Data Sheet (MSDS) is a
document that contains information on the
potential health effects of exposure to chemicals,
or other potentially dangerous substances, and
on safe working procedures when handling
chemical products.

3. History
• The earliest written material has been found in
the tombs of the Egyptians, either on the walls of
their tombs or on papyrus records.
• These date back over 4,000 years and include
the prescriptions of Imhotep, the first great
Egyptian physician.

4. Material Safety Data Sheets
• Include specific chemical identity and common
names
• Must provide information about:
▫ Physical and chemical characteristics
▫ Health effects
▫ Exposure limits
▫ Carcinogenicity (cancer-causing)
▫ Identification (name, address, and telephone number)
of the organization responsible for preparing the sheet
▫ Must be readily accessible to employees in their work
area

5. Who prepares and provides MSDSs?
• Manufacturers and importers of dangerous
goods and hazardous substances must:
• prepare an MSDS for each of their products
• provide the current MSDS to employers or
occupiers of premises where the product is used
or stored
• review and revise each MSDS as often as
necessary and at least every 5 years to make sure
that the information is accurate and up to date

toxic gas
 Up to: -
 R66: Repeated exposure may cause skin
dryness or cracking
 R67: Vapours may cause drowsiness and
dizziness
 R68: Possible risk of irreversible effects

7. Types of hazards
• When you read an MSDS, you should keep in mind that there are three
main types of hazards which can be related to the use of a chemical product:
• - Health Hazards. For example, skin contact with strong acids
will cause burns.
• - Fire Hazards. For example, propane burns very easily and
may explode.
• - Reactivity Hazards. For example, mixing ammonia and
household bleach will result in the release of a harmful gas.
• In addition, international format MSDSs include information
on environmental hazards (hazards to the natural
environment).

10. Oxidizer
• An oxidizer is a type of chemical
which a fuel requires to burn.
• Most types of burning on Earth
use oxygen, which is prevalent in
the atmosphere. However in
space there is no atmosphere to
provide oxygen or
other oxidizers
• so rockets need to carry up their
own oxidizers.

11. Flame
• Flammables
• Pyrophorics- ignite around 55
Degrees(uranium ,iron sulphide)
• Self-Heating
• Emits Flammable Gas
• Self-Reactives

12. Exploding Bomb
• Explosives
• Self-Reactives
• Organic Peroxides

toxic)

14. Corrosion
• Skin Corrosion/Burns
• Eye Damage
• Corrosive to Metals

16. Health Hazard
• Carcinogen
• Mutagenicity
• Reproductive Toxicity
• Respiratory Sensitizer
• Target Organ Toxicity
• Aspiration Toxicity

19. First aid Measures
EYE Contact:
• Check for and remove any contact lenses.
Immediately flush eyes with plenty of water for
15 mins. Get medical attention immediately.

20. Skin Contact
• Immediately flush skin with plenty of water for
at least 15 mins while removing contaminated
clothing and shoes.
• Cover the irritated skin with emollient .
• Get medical attention immediately.

21. Inhalation
• Remove to fresh air.
• If not breathing give artificial breathing
Warning –it may be hazardous to person
providing the aide.
• If breathing is difficult ,give oxygen.
• Get medical attention immediately.

22. Ingestion
• If swallowed ,don’t induce vomiting unless
directed by the medical professional.
• Never give anything by mouth to an
unconscious person.
• Loosen tight clothing such as collar, tie belt or
waistband.
• Get medical attention immediately.

23. Need of MSDS and how to prepare.
• In 1993, the American National Standard for
Hazardous Industrial Chemicals – Material Safety
Data Sheets – Preparation, ANSI Z400.1 was
developed to address the need for a MSDS format that
was comprehensive, understandable and consistent.
• ANSI Z400.1-1993 introduced the standardized
16-section MSDS.
• Revisions were made to the Standard in 1998 and
2005. The 2005 revisions improve readability,
minimize redundancies and reorder the MSDS
sections
