Which type of hazards includes explosive, reactive, or flammable materials?

The correct answer is chemical hazards. Chemical hazards are substances that can cause harm due to their physical and chemical properties. This category includes explosive, reactive, and flammable materials, which can pose serious risks in various environments, particularly in industrial or laboratory settings.

Understanding chemical hazards is crucial because they can lead to accidents that may result in fires, explosions, or toxic releases, affecting both health and environmental safety. Workers in industries handling these materials must be trained to recognize and manage chemical hazards appropriately to maintain a safe working environment.

Physical hazards, on the other hand, are related to physical agents that can cause harm, such as slips, trips, falls, and machinery-related injuries, rather than the inherent properties of materials. Health hazards include biological or ergonomic risks that can affect health over time. Environmental hazards pertain to risks that affect the natural environment rather than immediate danger to individuals. Hence, recognizing chemical hazards is critical for ensuring safety in settings where such materials are present.
