Understanding CSA Requirements for Safety Shoes and Work Boots

According to the National Safety Council, 1 out of every 4 foot injuries sustained in the workplace are caused by workers not wearing the proper protective footwear. Keeping feet protected and safe from harm was the impetus behind creating of safety standards for protective footwear certified by the CSA Group. By providing CSA-approved protective footwear and requiring its use, for example, the Ontario construction industry reduced the frequency of foot injuries by 60 percent between 1968 and 1984.

The CSA category known as CSA Z195- Protective Footwear has grown from its original scope and now covers design & performance requirements. You can find more details from CSA here CSA Z195:14 (R2019) | Product | CSA Group

So what do the CSA symbols you see on safety shoes and work boots mean?

Selection of Safety Footwear

Marking

Criteria

Intended Application

CSA Green Triangle

Green triangle indicates sole puncture protection with a Grade 1 protective toe cap.

For industrial work environments, especially that of construction where sharp objects (such as nails) are present. 

CSA Blue Square

Blue rectangle indicates a Grade 1 protective toe cap with no puncture-resistant sole.

For industrial work environments not requiring puncture protection.

CSA ESR

White rectangle with orange Greek letter omega indicates electric-shock protective footwear.

For industrial work environments where accidental contact with live electrical conductors can occur. Warning: Electrical shock resistance deteriorates with wear and in a wet environment.

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. Range of 106   to 108   (1-100 megaohms)

For industrial work environments where a static discharge can create a hazard for workers or equipment. Warning: This footwear should not be used where contact with live electrical conductors can occur.

SD Plus CSA

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. SD+ is a more Narrow Range of 106   to 3.5 x 107   (1-35 megaohms) providing a consistent level of static dissipation to industries where this is important.

For industrial work environments where a static discharge can create a hazard for workers or equipment. Warning: This footwear should not be used where contact with live electrical conductors can occur.

CSA Red Patch

Red rectangle with white C letter indicates electrically conductive footwear.

For industrial work environments where low-power electrical changes can create a hazard for workers or equipment. Warning: This footwear should not be used where contact with live electrical conductors can occur.

CSA Met Patch

Dark grey rectangle with M letter indicates metatarsal protection. Note: Toe protection is required for all metatarsal protective footwear.

For industrial work environments where heavy objects can hurt the metatarsal region of the foot.

CSA Chainsaw Patch

White label with green fir tree symbol footwear provides protection when using chainsaws.

For forestry workers and others who work with or around hand-held chainsaws and other cutting tools.

  • Green triangle: for any industrial or heavy work environment, including construction, where sharp objects (such as nails) are present.
  • Blue rectangle: industrial work that does not require puncture protection.
  •  puncture protection.
  • Yellow triangle: light industrial work environments that need both puncture and toe protection.
  • White patch with orange Greek letter "omega": footwear with soles that provide electric shock resistance for industrial environments where accidental contact with live electrical conductors can occur.
  • Yellow rectangle and green letter "SD" accompanied by grounding symbol: industrial environments where a static discharge can be a hazard for workers or equipment.
  • Red rectangle and black letter "C" and grounding symbol: environments where low-power electrical charges can be a hazard for workers on equipment. 
  • White label with green FIR tree: forestry workers and those who work with or around hand-held chainsaws and other cutting tools.
