Final answer:
It is false that the OSHA construction standard requires flexible cords to be rated four. OSHA standards include extensive requirements for safety, not limited to a specific rating on cords.
Step-by-step explanation:
The statement that 'The OSHA construction standard requires flexible cords to be rated four' is false. The actual requirement by OSHA standards for construction is not simply about a 'rating of four', but rather it encompasses a wide range of safety measures designed to protect workers from various hazards on construction sites. These safety measures include, but are not limited to, fall protection, trenching cave-in prevention, exposure control to infectious diseases, confined space safety, chemical hazard prevention, machine guarding, respiratory protection, and necessary safety training in a comprehensible language for workers.
OSHA's standards are detailed to ensure worker safety for those working with electrical equipment, including specifications for the proper use of flexible cords. The standards require cords to be durable and suitable for the conditions of use, and there may be specific requirements regarding their electrical rating, but there is no blanket requirement for a 'rating of four' as the statement suggests.
