Which class represents Flammable Solids?

The correct answer is Class 4, which encompasses flammable solids, including various substances that can ignite and burn readily when exposed to heat, friction, or a source of ignition. This class specifically includes materials that may result in fire hazards, especially in industrial settings where they may be improperly stored or handled.

Understanding the classification of flammable solids is crucial for safety measures in environments where these materials are present. Adequate precautions, such as using compatible storage containers and implementing effective fire prevention strategies, are vital to mitigate risks associated with Class 4 materials.

In contrast, other classes represent different types of hazardous materials. Class 2 pertains to gases, including flammable and non-flammable gases. Class 5 deals with oxidizing substances and organic peroxides, which can greatly enhance fire conditions but are not classified as solids. Class 6 is reserved for toxic and infectious substances, which have entirely different risks associated with them. Recognizing these distinctions is important for safe industrial practices and ensuring proper handling protocols are applied based on the material involved.
