In the workplace, fire extinguisher training should typically be conducted annually. This is to ensure that employees are well-prepared to respond effectively in case of a fire emergency. Regular training helps to familiarise workers with the proper use of fire extinguishers and reinforces fire safety protocols. This therefore contributes to a safer working environment. However, the exact frequency may vary depending on the specific workplace and its risk assessment, so it’s advisable to consult with local authorities and follow any regulations or recommendations they provide.
