Final answer:
Deckers in a Controlled Decking Zone must be protected at heights greater than 6 feet, according to OSHA standards. This safety regulation is enforced to prevent falls and injuries on construction sites.
Step-by-step explanation:
The question pertains to safety measures in a construction area known as a Controlled Decking Zone (CDZ). When it comes to such safety practices, the Occupational Safety and Health Administration (OSHA) stipulates specific guidelines which determine at what height fall protection is required. In the case of deckers working within a CDZ, OSHA standards require that fall protection be provided for employees working over 6 feet above lower levels. This is to ensure the safety and health of workers who are at risk of falling from heights on construction sites.
Therefore, the correct answer to the student's question is b) 6 feet. Any decker working in a Controlled Decking Zone must be protected if they are working at heights greater than 6 feet. This rule is a critical component of worksite safety and is enforceable by law. Recognizing and adhering to OSHA regulations, including this fall protection requirement, is essential for maintaining a safe construction environment. Managers and workers alike must be familiar with these heights to ensure adequate protection measures are in place.
