Which OSCAR standard pertains to rooftop safety?

The correct choice concerning rooftop safety is B, 1926.501. This standard is part of the Occupational Safety and Health Administration (OSHA) regulations specifically addressing construction safety. It outlines the requirements for fall protection in construction activities, which includes work performed on roofs.

Rooftops often pose significant risks due to heights and the potential for falls, making it essential to have specific regulations in place to protect workers involved in these activities. This standard mandates that safety measures, such as guardrails, safety nets, or personal fall arrest systems, must be utilized whenever employees are working at heights where there's a risk of falling.

Understanding these standards helps ensure that workers are protected and that employers comply with safety regulations, ultimately reducing the incidence of accidents and fatalities related to rooftop work.
