Answer :
The new ASTM standards for footwear specify that it should D) all of the above.
The standards specify that footwear should have the following characteristics:
Impact and compression resistance at the toe: This means the footwear must be able to withstand heavy forces and prevent injury to the toes from falling objects or compression forces.
Reduction of electrical conductivity: This is crucial to avoid static buildup which could ignite flammable gases. In workplaces where flammable materials or gases are present, reducing electrical conductivity helps prevent accidental ignition.
Puncture resistance: This ensures the soles of the footwear are robust enough to protect the feet from sharp objects that could pierce through.
