How many fusees must be carried when performing flagging duties?

When performing flagging duties, the correct number of fusees that must be carried is five. This requirement ensures that the flagger has an adequate supply of fusees to effectively communicate with train operators in the event of an emergency or when signaling for trains to stop. The use of five fusees provides a balance between having a sufficient quantity to maintain visibility and safety without carrying an excessive load. Carrying this number also aligns with operational guidelines that emphasize preparedness while on the tracks, ensuring that personnel are equipped to handle various situations that might arise during flagging operations.
