What safety measure is necessary when working with materials unsuitable for water extinguishing?

When working with materials that are unsuitable for water extinguishing, having dry agents on hand for extinguishing is essential for effective fire management. Certain substances, such as flammable metals or specific chemicals, can react negatively with water, potentially exacerbating the fire or creating hazardous situations. Dry chemical extinguishers, such as those containing sodium bicarbonate, potassium bicarbonate, or dry powder agents designed for specific fires (like Class D fires), are effective alternatives in these situations, allowing for safe suppression without the risk of a dangerous reaction.

The rationale behind this safety measure is to ensure that the right type of extinguishing agent is readily available to address the specific fire hazard without further complicating the situation. This proactive approach helps maintain safety and reduces the risk of injury or damage when dealing with hazardous materials.
