Final answer:
Three methods to prevent falls include using a safety harness and anchor point, installing guardrails or barricades, and using safety nets. OSHA regulations require employers to ensure these measures are in place to protect employees from fall hazards.
Step-by-step explanation:
To prevent an employee from falling off an unprotected side or edge that is 6 feet above the lower level, three major safety measures can be employed. These are: using a safety harness and tying off to an anchor point, installing guardrails or barricades around the edge, and implementing a fall protection system such as a safety net.
OSHA standards mandate that employers must provide adequate fall protection. This includes ensuring that any time an employee may be exposed to fall hazards, proper safety measures are in place. For example, when dropping objects from a height, it is crucial to ensure the area is clear of people or vehicles to prevent injury or damage.
Understanding the physics of falls is also important for workplace safety. For example, the severity of a fall on the Moon would be less than a fall on Earth due to the Moon's lower gravitational acceleration. This is a simple illustration of how various factors can affect the risks associated with falls at a worksite.
