The CSA Green Triangle indicates sole puncture protection with a Grade 1 Protective toe to withstand impacts up to 125 joules. Sole puncture protection is designed to withstand a force of not less than 1200 Newtons.
The CSA Yellow rectangle with a green “SD” and grounding symbol indicates soles are static-dissipative. The outer soles are made from an antistatic compound, capable of dissipating an electrostatic charge in a controlled manner. The test criteria are 106 to 108 Ohms. Note that SD footwear without toe protection will not have sole protection certified by CSA.
