In workplaces where fire extinguishers are likely to be used, hands-on training is essential, as theory cannot replace practical experience. Such training builds confidence, familiarizes users with the weight and operation of the extinguisher, and emphasizes the importance of understanding the manufacturer’s instructions. Realistic simulations also help individuals reflect on and improve their emergency response.
