Final answer:
A system that uses raised warning lines to limit exposure to unguarded edges is termed a Control Zone. It is a part of OSHA standards which also includes various other protective measures for workplace safety such as fall protection. These standards ensure a safe working environment is maintained to avoid recognized serious hazards.
Step-by-step explanation:
Any system that uses raised warning lines to limit the worker's exposure to an unguarded edge is known as a Control Zone. This method of fall protection delineates an area where certain types of work may take place without conventional fall protection methods such as guardrails or safety net systems at that specific point. It is a part of the Occupational Safety and Health Administration's (OSHA) standards, which require employers to establish control zones with the use of control lines or similar measures to mark off areas where traditional fall protection is not feasible.
OSHA's safety regulations are comprehensive. They mandate that employers provide adequate fall protection and proactive measures to guard against various workplace hazards. They cover a broad range of standards that also include preventing trenching cave-ins, exposure to infectious diseases, safety in confined spaces, chemical hazards, machine guarding, and ensuring proper use of personal protective equipment (PPE). In cases where specific OSHA standards do not apply, the General Duty Clause of the OSH Act pushes employers to make the workplace free from recognized serious hazards.
