Chlorinated flame retardants are chemical compounds added to materials to reduce the risk of fire. They work by slowing down the ignition and spread of flames in products like furniture, electronics, and textiles. These substances are often used in items that are at higher risk of catching fire, helping to enhance safety in homes and workplaces. However, concerns have been raised about the environmental and health impacts of chlorinated flame retardants. Some studies suggest that these chemicals can accumulate in the environment and in living organisms, potentially leading to harmful effects. Regulatory agencies are evaluating their use to ensure safety for both people and the planet.
