According to Jackie’s Law, what is the minimum protection requirement for excavations?

Jackie's Law, which pertains to safety requirements for excavations, emphasizes the necessity of preventing unauthorized access to areas where workers are at risk. The correct option, which states that the minimum protection requirement is at least a 6 ft fence or 3/4" steel metal plates, reflects the intention to provide substantial physical barriers that can prevent accidents or injuries.

A 6 ft fence serves as an effective means of deterring entry into an excavation site, ensuring that individuals stay clear of potential hazards. Similarly, using 3/4" steel metal plates provides a strong, durable physical safeguard that can prevent access while also protecting the integrity of the site itself. Together, these measures align with workplace safety standards aimed at reducing the risk of accidents in potentially dangerous situations.

Other options do not meet the established criteria for safety as per Jackie’s Law. A 5 ft fence may not provide adequate deterrence, and the mere provision of a hard hat and safety glasses does not address site security comprehensively. Thus, the choice of at least a 6 ft fence or 3/4" steel metal plates stands out as the proper method of ensuring safety in excavation areas.
