signalword - indicates chemical's hazard level
GHS symbols or hazard pictograms - represents the kind of physical, health, and/or environmental hazards associated with the chemical
manufacturer or supplierinformation - identifies the manufacturer's company name, address, and telephone number
precautionary statements or firstaid - 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
hazardstatements - describes the nature of the hazards of a chemical including the degree of hazard where appropriate
product name or identifiers - gives the unique name or number of the chemical
primaryreagentcontainer
include bottles, cans, plastic containers, and cylinders which come directly from the manufacturer
contains solid and liquid chemicals and are usually stored in the stock room
primary reagent container has a default label once received from the supplier or dealer
important to retain its original label
secondary reagent container
large reagent bottles containing solutions prepared in significant quantities
in addition to the product name, signal word, pictograms, and precautionary and safety measures, the label includes details such as the preparer's name, date of preparation, expiration date (if applicable), and recommended storage conditions
workingreagentbottles
small containers found in the laboratory room and are used for laboratory experiments
contain solutions obtained from secondary reagent containers, as well as pure solid and liquid chemicals transferred from the primary reagent containers
symbol of the chemical and the pictogram are included in the label of working reagent bottles
section 1 - identification
describes the GHS information requirements for SDS
includes: identity of the substance, name of supplier, recommended uses of the chemical mixtures or product, contact detail, emergency contact
section 2 - hazardidentification
include a summary and/or conclusion of the data given, that even non-experts can identify all the hazards for the hazardous substance or mixture
section 3 - composition or informationon ingredients
identify the ingredients of the product
section 4 - first aid measures
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
section 5 - fire-fightingmeasures
cover the requirements for fighting a fire caused by the substance or mixture or arising in its vicinity
section 6 - accidentalreleasemeasures
recommend the appropriate responses to spills, leaks, or releases to minimize the adverse effects on persons, property, and the environment
also distinguish the response to small and large spills
section 7 - handling and storage
describe the guidance on safe handling practices that minimize the potential hazards to people, property, and the environment from the substance or mixture
section 8 - exposurecontrols or personalprotection
provide guidance on "occupational exposure limits" and exposure controls necessary to minimize worker and environmental exposure
section 9 - physical and chemicalproperties
describe the empirical data of the substance or mixture
section 10 - stability and reactivity
this section shall describe the reactivity hazards of the substance or mixture
section 11 - toxicologicalinformation
provide information to be used by medical professionals, occupational health, safety professionals, and toxicologists
section 12 - ecologicalinformation
provide information to evaluate the environmental impact of the substances or mixture if it is release to the environment
section 13 - disposalconsideration
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
section 14 - transportinformation
provide basic classification information for the transporting shipment of hazardous substance or mixture by road, rail, sea, or air
section 15 - regulatoryinformation
describe any other regulatory information on the substance or mixture that is not provided elsewhere in the SDS
section 16 - otherinformation
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.
