ISO 20347:2021: basic and optional occupational-footwear requirements must return to actual work risk

ISO 20347:2021 addresses basic and additional requirements for general-purpose occupational footwear, including mechanical, slip, thermal, and ergonomic risks. It also states that some special risks are covered by other job-related standards.

Source-backed points

• ISO shows Edition 3 published in December 2021.
• The public abstract lists mechanical, slip, thermal, and ergonomic considerations.
• Special risks such as firefighting, electrical insulation, chemicals, and molten-metal splash need complementary job-related standards.

Editorial context

Workwear procurement often underweights the footwear–garment combination. Protective goal, sizing, hosiery, floor conditions, cleaning, maintenance, and replacement cycle all belong in the overall PPE plan; footwear should not be selected only by appearance or one metric.

Use boundary and next step

• Investigate slip, heat, chemical, and electrical risks separately.
• Run real wear trials for prolonged standing, climbing, and wet work.
