A PPE ensemble weighs at least:

The correct weight for a Personal Protective Equipment (PPE) ensemble is significant to ensure that firefighters are adequately prepared for dangerous environments while maintaining the necessary level of mobility and safety. An ensemble weighing at least 40 lb (18 kg) aligns with industry standards that account for the various components of PPE, including the fire-resistant suit, helmet, boots, gloves, and any additional equipment needed to protect against heat, flames, chemicals, and physical hazards. This weight ensures that the gear provides sufficient protection without overly compromising the firefighter's mobility and endurance during operations. Choosing an ensemble weighing less than this threshold could potentially lead to inadequate protection in high-risk situations.
