Need to know in Safety Data Sheet (SDS)

This fact sheet will help you understand the information contained in a safety data sheet (SDS), what each section in the SDS means and how to check if a SDS complies with the Work Health and Safety (WHS) Regulations.

By reading, understanding and following the information and instructions in an SDS, all chemicals should be able to be used safely in the workplace.

An SDS is a document that provides detailed information about a hazardous chemical, including:

·         the identity of the chemical product and its ingredients,
·         the hazards of the chemical including health hazards, physical hazards and environmental hazards,
·         physical properties of the chemical, like boiling point, flash point and incompatibilities with other chemicals,
·         workplace exposure standards for airborne contaminants,
·         safe handling and storage procedures for the chemical,
·         what to do in the event of an emergency or spill,
·         first aid information, and
·         transport information.

The information in an SDS is arranged under 16 headings to allow relevant information to be easily located by the person using the chemical.  The 16 sections of an SDS are described in further detail below. 

Why should I read the SDS?

The SDS is a key information resource for workers and persons conducting a business or undertaking in managing the risks of a hazardous chemical in a workplace.  It is important that workers read the SDS carefully and understand its contents before working with a hazardous chemical so that it can be safely stored, handled or used in the workplace. 

Not all information about the hazards of a chemical or instructions for safe storage, handling and use may be provided on labels.  In most cases, the SDS will contain much more information about a hazardous chemical than appears on the label.  

The SDS can be used to assist in assessing specific risks associated with a chemical and in training workers on how to use a chemical safely.

Where do I get an SDS from?

The supplier of a hazardous chemical must provide, free of charge, a copy of the manufacturer or importer’s SDS with the chemical on first supply to the workplace or when asked to do so. If the supplier has not provided you with an SDS for the chemical you are using, you should ask for it before working with that chemical. If the supplier will not provide you with an SDS after being asked for it, then contact your local work health and safety (WHS) regulator.

Check if the SDS complies with the WHS Regulations

You should always check that the SDS relates to the chemical that you have received or are using.  This can easily be done by checking that the product or chemical name on the SDS is the same as on the product label of the container. 

Before using a chemical in the workplace, you should also make some simple checks to see whether it complies with the WHS Regulations. 

·           Is the SDS written in English? 
·           Does the SDS contain 16 separate headings?  These, and the contents of each section, are further discussed below. 
·           Does the SDS state the name, address and business telephone number of the Australian importer or manufacturer?
·           Does the SDS give an Australian business telephone number from which further information about the chemical can be obtained in an emergency?
·           Was the SDS prepared within the last five years?

If you cannot answer yes to all of the above questions, the SDS you have been given does not comply with the WHS Regulations.  In this instance, you should contact the supplier, importer or manufacturer for an up-to-date and compliant SDS and refrain from using the chemical until you obtain the correct SDS.  

If the supplier cannot or will not provide a compliant SDS, contact your local work health and safety regulator. 

Keeping SDS in the workplace

A register of hazardous chemicals used, handled or stored at the workplace must be prepared and kept up-to-date at the workplace and must also include the current SDS for each of these chemicals.

This register must be readily available to all workers who use or may be affected by the chemicals at the workplace.

What information is on an SDS?

An SDS which complies with the WHS Regulations contains the following 16 separate sections each with specific information relating to the chemical being used, handled, stored, transported or disposed.
Section 1 - Identification:
Contains the product identifier or tradename,  contact details of the manufacturer or importer responsible for supplying the chemical, and the telephone number to contact in case of an emergency. The information in this section should be consistent with the label.

Section 2 – Hazard(s) identification
Gives details on the potential health and physical hazards of the chemical. This information can be used to help assess the risks to the health and safety of workers, other people, and the environment. The information in this section should be consistent with the information on the label. In some cases there may be more information on the SDS than on the label.

Section 3 - Composition and information on ingredients
If the chemical is a mixture, this section should provide the information on the identity and proportions of hazardous ingredients in the mixture.

Section 4 - First-aid measures
Describes the necessary first aid measures to be taken in case of an accident.

Section 5 - Fire-fighting measures
Gives specific information on fighting a fire involving the chemical, including the most suitable extinguishing media and other protective measures.

Section 6 - Accidental release measures
Describes what actions need to be taken if there is an accidental release or spill of the chemical to minimise adverse effects on people, property and the environment.

Contains details on how to handle and store the chemical safely to minimise the potential risks to people, property and the environment.

Section 8 - Exposure controls and personal protection
Provides information on control measures that can be used to reduce exposure, for example, engineering controls, information on exposure standards and guidance on required personal protective equipment (PPE).

Section 9 - Physical and chemical properties
Provides detailed information on the physical and chemical properties of the chemical, for example, appearance, odour, pH, flash point, melting/boiling point or any other relevant physical data.

Section 10 - Stability and reactivity
Contains details of any hazardous reactions that may occur if the chemical is used under certain conditions and details of any incompatible materials

Section 11 - Toxicological information
Provides detailed information on the toxicological properties of the chemical. This section is used primarily by medical professionals, toxicologists and WHS professionals.

Section 12 - Ecological information
Provides detailed information on the ecological hazard properties of the chemical.

Section 13 - Disposal considerations
Explains how the chemical should be disposed of correctly or recycled or reclaimed.

Section 14 - Transport information
Contains basic classification information like UN number and transport hazard classes and packing groups that relate to the transport of the chemical by road, rail, sea or air. 

Section 15 - Regulatory information
Provides advice on other international or national regulatory information specific to the chemical, such as the Montreal protocol (ozone depleting substances), the Stockholm Convention(Persistent organic pollutants), Poisons scheduling or any other applicable Australian prohibition, notification or licensing requirements.

Section 16 - Any other relevant information
Provides any other information relevant to the preparation of the SDS, including the date of its preparation, a key or legend to abbreviations acronyms and references used.

How will I know if an SDS has been updated?

Every SDS must provide a date of last revision in Section 16 – Other Information. You will know if an SDS has been updated by checking this date, and comparing it to the one on any previous SDS you have.
Note that there is no requirement for the supplier to provide an updated SDS to past purchasers of a hazardous product. However, it continues to be good practice to provide this information to purchasers who may still be using the product.

As an employer, do I have responsibilities for SDSs?
Employers will be required to make sure that all hazardous products (as defined by the Hazardous Products Regulations have an up-to-date SDS when it enters the workplace. The SDSs must be readily available to the workers who are exposed to the hazardous product, and to the health and safety committee or representative.
Employers may computerize the SDS information as long as:

·         all employees have access to and are trained on how to use the computer or device,
·         the computers/devices are kept in working order, and
·         the employer makes a hard copy of the SDS available to the employee or health and safety committee/representative upon request.

As mentioned, in some circumstances, an employer may be required to prepare an SDS (e.g., when the product is produced and used in the workplace).
Why is my SDS so hard to understand?
SDSs have many different audiences including occupational hygienists and safety professionals, employers, supervisors, nurses, doctors, emergency responders, and workers. To ensure that SDS users can quickly find the information that they need, information directed toward these various users will be listed in specific sections. Having a set format will make it easier to find the information you need on every SDS.
Is all the information I need on the SDS?

Not necessarily. A lot of health hazard information, for example, is written in general terms. In addition, SDSs are often written for many different uses or applications of the product, and the handling and safety precautions may not be specific to your workplace. Your health and safety committee or representative, health and safety specialist, occupational health nurse or family doctor, supervisor, employer, or supplier should be able to help you find more information if needed.

With the exception of Sections 12-15, the supplier is required to provide information on each specific information element required on the SDS. In some cases, it may be appropriate for the supplier to state “not available” or “not applicable” instead of providing the specific information.
·         "Not available" means that the information could not be located or does not exist. For example, if the supplier cannot locate any studies that measure the odour threshold, which is reported in Section 9 of the SDS, the supplier would report "not available".
·         "Not applicable" means that the information element is not relevant. For example, if the product is odourless, then the odour threshold would be reported as "Not applicable".

Note that the supplier should not use the abbreviation "n.a." or "NA" without defining it, as it could mean "not applicable" or "not available" or something entirely different.
As a worker, when would I use an SDS?

Always be familiar with the hazards of a product before you start using it. You should look at an SDS, match the name of the product on the container to the one on the SDS, know the hazards, understand safe handling and storage instructions, as well as understand what to do in an emergency.
You can think of the SDS as having four main purposes. It provides information on:
  1. Identification: for the product and supplier.
  2. Hazards: physical (fire and reactivity) and health.
  3. Prevention: steps you can take to work safely, reduce or prevent exposure, or in an emergency.
  4. Response: appropriate responses in various situations (e.g., first-aid, fire, accidental release).
For most people who work with hazardous products, you should always:
  • read the name of the chemical (Section 1),
  • know the hazards (Section 2),
  • understand safe handling and storage instructions (Section 7), and
  • understand what to do in an emergency (Sections 4, 5 and 6).
A few things to know:
  • Make sure that the product is being used in the way the manufacturer intended; otherwise the advice provided on the SDS and label may not apply, or the protective measures listed may not be adequate. Section 1 of the SDS should describe the typical use of the product and may indicate restrictions. Ask your supervisor or a health and safety professional for advice if the way you use the product does not match the SDS.
  • Section 2 will summarize the hazards related to the product, precautions to take, and what to do in an emergency. Understand that the SDS covers information about the potential hazards, but may not be specific about the required safe work procedures needed for your workplace (e.g., the SDS may not specify what type of respirator must be used, just that a respirator is needed). More information can be found by asking your supervisor. These decisions may require the help of a safety professional or someone with chemical safety knowledge.
