Question

the new astm standards for footwear specify that it should: be impact and compression resistant at the toe reduce electrical conductivity to avoid static that could cause ignition of flammable gases be puncture resistant all of the above

Explanation:

Step1: Analyze each option

• The first option about being impact and compression resistant at the toe is a valid safety requirement for footwear.
• The second option regarding reducing electrical conductivity to avoid static - induced ignition of flammable gases is also a crucial safety aspect.
• The third option of being puncture - resistant is another important safety feature.

Step2: Check the "All of the above" option

Since all the individual options (impact and compression resistance at the toe, reducing electrical conductivity, and puncture resistance) are valid requirements for footwear as per safety standards, the "All of the above" option is correct.

Answer:

All of the above.
