Section 5 – Fire-fighting Measures
Section 5 sets out how to control a fire involving the chemical safely. When you examine what information is on a safety data sheet, this section identifies the extinguishing media you should use, such as foam, dry powder, or carbon dioxide, depending on the substance. It also explains the protective equipment firefighters must wear, including breathing apparatus and chemical-resistant clothing. In addition, it highlights special hazards, such as toxic fumes or explosive reactions that may occur when the material burns.
Section 6 – Accidental Release Measures
Section 6 explains how to respond when a spill or leak occurs. This section outlines the emergency actions you must take to protect people on site. It specifies how to contain the spill, whether by using barriers, absorbents, or ventilation, and details the correct clean-up methods. It also stresses the importance of preventing contamination of soil, drains, or waterways. By following these instructions, you reduce risks to both people and the environment.
Section 7 – Handling and Storage
The section on handling and storage sets out the rules for using and keeping the chemical safely. It explains the handling practices that reduce risks, such as avoiding direct contact, using protective equipment, and working in ventilated areas.
This part of the SDS also details the correct storage conditions. It includes temperature limits, container requirements, and the need for secure labelling. In addition, it highlights incompatible materials that could trigger dangerous reactions if stored together.
Section 8 – Exposure Controls and Personal Protection
Section 8 defines the safeguards you must apply to reduce harm from chemical exposure. When you review what information is on a safety data sheet, this section lists the exposure standards that set legal or recommended limits for safe use.
It then describes engineering controls, such as local exhaust ventilation or enclosed processes. These measures prevent hazardous concentrations from building up in the workplace. Finally, it specifies the personal protective equipment workers must wear, including gloves, respirators, goggles, or protective clothing.
Section 9 – Physical and Chemical Properties
Section 9 sets out the measurable traits of the chemical so you can identify it accurately and predict how it will behave. It lists details such as the substance’s appearance, colour, and odour, which help you confirm you have the correct material. It also provides numerical data, including pH level, melting point, boiling point, and flash point, which indicate how the chemical reacts under heat or pressure. Other relevant properties, like solubility or vapour density, may also be included.
Section 10 – Stability and Reactivity
This part of the sheet explains how a chemical behaves and under what conditions it may become dangerous. It specifies whether the substance remains stable during normal storage and handling or if it can break down over time. You also see details about possible hazardous reactions, such as the release of toxic gases, ignition, or pressure build-up when exposed to heat or other triggers. Just as importantly, the sheet lists incompatible materials that could cause violent reactions if they come into contact.
Section 11 – Toxicological Information
Toxicological details explain how a substance harms the body, ranging from short-term effects like headaches or skin burns to chronic impacts such as organ damage or cancer. The document highlights the paths chemicals take into the body, whether through inhalation of vapours, accidental swallowing, or absorption through the skin and eyes. It also lists early warning signs, including nausea, coughing, or blurred vision, alongside risks that may appear only after long-term exposure.
Section 12 – Ecological Information
This section explains how a chemical interacts with the environment, including its potential to harm plants, animals, and waterways.
