Which control measure would be used to control the hazard of being crushed between the counterweight and the crane chassis?

• A. Barricading
• B. PPE
• C. Warning signs
• D. Exclusion zones

Answer: (A)

The hazard comes from a moving crane part—specifically the space between the counterweight and the crane chassis—which can crush a person who enters the area. The most effective way to prevent this is to create a solid barrier that keeps workers out of that danger zone. Barricading physically blocks access, so even if someone forgets or signs are overlooked, they can’t reach the space where a crush could occur. PPE can’t stop a crush, and warning signs don’t prevent entry. Exclusion zones aim to keep people away, but barricading provides the actual barrier that stops access.
