What is the general guideline for replacing a safety helmet?

The guideline regarding the replacement of a safety helmet emphasizes the importance of maintaining the helmet's integrity and protection capabilities. When a helmet shows visible signs of damage, such as cracks, dents, or other forms of wear and tear, it may no longer provide adequate protection to the wearer. Additionally, if the helmet has experienced an impact, even if no visible damage is evident, it should also be replaced. This is due to the fact that the internal structure of the helmet might have been compromised, reducing its effectiveness in future impacts.

Regular inspections and awareness of the helmet's condition are crucial for ensuring safety in any environment where head protection is necessary. By adhering to this guideline, workers can better protect themselves from potential head injuries that may arise in hazardous work environments.
