A Material Safety Data Sheet (MSDS) provides vital information on health risks and safe handling of chemicals. It outlines essential details including chemical identity, health effects, exposure limits, and necessary first aid measures. Manufacturers are required to create and maintain these sheets, ensuring accessibility for employees to promote a safe working environment.

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

6. Risk phrases - examples

compounds
• R5: Heating may cause an explosion
• R6: Explosive with or without contact with air

cause fire
• R9: Explosive when mixed with combustible
material
• R10: Flammable
• R11: Highly flammable
• R12: Extremely flammable

flammable gases
 R20: Harmful by inhalation
 R21: Harmful in contact with skin
 R22: Harmful if swallowed
 R23: Toxic by inhalation
 R24: Toxic in contact with skin
 R25: Toxic if swallowed
 R26: Very toxic by inhalation
 R27: Very toxic in contact with skin
 R28: Very toxic if swallowed
 R29: Contact with water liberates toxic
gas.
 R30: Can become highly flammable in use
 R31: Contact with acids liberates toxic gas

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

13. Skull and Crossbones
• Acute Toxicity (fatal or
toxic)

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

15. Gas Cylinder
• Gases Under Pressure

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

17. Environment
• Aquatic 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
