CHEMICAL HAZARD SYMBOLS AND REAGENT LABELS | ACTIVITY 2

Chemicals

are indispensable tools that individuals working in any laboratory

use to conduct experiments.

Chemical Hazard symbols

symbols used to warn the hazards associated

with the use of the chemical.

globally harmonized system or GHS 

Chemical hazard symbols are symbols used to warn the hazards associated

with the use of the chemical. It is based on the ******* and ***** 

Globally Harmonized System

establishes an internationally agreed-upon framework for

standardizing chemical hazard classification and communication.

Health Hazard

Exlamation mark

Corrosion

Gas Cylinder

Environment

Flame

Explosive Bomb

Skull and

Crossbones

Flame Over

Circle

Signal Word

indicates chemical’s hazard level.

GHS Symbols or

Hazard Pictograms

symbol represents the kind of physical,

health, and/or environmental hazards associated

with the chemical.

Manufacturer/

Supplier Information

This identifies the manufacturer’s company name,

address, and telephone number.

Precautionary

Statements/

First Aid

provides measures that should be taken to

minimize or prevent adverse effects resulting from

exposure to a hazardous chemical including first-

aid instructions, if necessary.

Hazard Statements

It describes the nature of the hazards of a chemical

including the degree of hazard where appropriate.

Product Name or

Identifiers

It gives the unique name or number of the

chemical.

Secondary Reagent Containers

Large reagent bottles containing solutions prepared in significant

quantities are also categorized as

preparer's name,

date of preparation, expiration date (if applicable), and recommended

storage conditions.

In addition to the product name, signal word, pictograms, and precautionary

and safety measures, the label includes details such as the***** , *******, ******* ,****** (secondary reagent container)

Working reagent bottles

are small containers found in the laboratory room

and are used for laboratory experiments. These bottles contain solutions

obtained from secondary reagent containers, as well as pure solid and liquid

chemicals transferred from the primary reagent containers.

Safety Data Sheet (SDS)

a multi-page chemical fact sheet with

specific information about each hazardous material (chemical) made by the

manufacturer and is intended to provide comprehensive information about the

chemical or compound.

Ambiguous or vague

**** ***** ***** statements such as

“may be dangerous”, “no health effects” are discouraged in SDS.

Identification

This section describes the GHS information

requirements for SDS. This includes the

following information:

• identity of the substance

• name of the supplier

• recommended uses of the chemical,

mixtures, or product

• contact details of the supplier

• emergency contact number

Hazard Identification

This section shall include a summary and/or

conclusion of the data provided, allowing even

non-experts to identify all hazards associated

with the hazardous substance or mixture.

Composition or Information on Ingredients

This section shall identify the ingredients of the

product.

First Aid Measures

This section shall describe the initial care that

can be given by an untrained responder without

the use of sophisticated equipment and without

a wide selection of medications available.

Fire-fighting Measures

This section shall cover the requirements for

fighting a fire caused by the substance or

mixture or arising in its vicinity.

Accidental Release

Measures

This section shall recommend the appropriate

response to spills, leaks, or releases to

minimize the adverse effects on persons,

property, and the environment.

Handling and Storage

This section shall describe the guidance on safe

handling practices that minimize the potential hazards to people, property and the enviroment from the substance or mixture.

Exposure controls/

personal protection

provide guidance on

“occupational exposure limits” and exposure

controls necessary to minimize worker and

environmental exposure.

Physical and chemical

properties

This section shall describe the empirical data of

the substance or mixture (if possible).

Stability and Reactivity

This section shall describe the reactivity

hazards of the substance or mixture.

Toxicological

information

provide information to be

used by medical professionals, occupational

health and safety professionals and

toxicologists.

Ecological Information

provide information to

evaluate the environmental impact of

the substances or mixture if it is released to the

environment

Disposal

Consideration

shall provide information for proper

disposal of the substance or mixture and/ or its

container to assist in the determination of safe

and environmentally preferred waste

management options.

Transport information

shall provide basic classification

information for the transportation of hazardous

substances or mixtures by road, rail, sea, or

air.

Regulatory information

This section shall describe any other regulatory

information on the substance or mixture that is

not provided elsewhere in the SDS.

Other Information

shall provide information relevant

to the preparation of the SDS. These include

the date of preparation of the latest revision of

the SDS, key/legend to abbreviations or

acronyms, references, etc.
