CSA Safety Boot Symbols Explained: Triangle, Omega & More

As an Amazon Associate, BetterPick Hub earns from qualifying purchases. Our picks are based on manufacturer specifications and buyer review patterns, not hands-on testing.

This guide is for anyone in Canada who has been told to wear “CSA boots” and is now staring at a row of coloured shapes on a label. Each symbol is a short code for a specific type of protection under CSA Standard Z195-14 (R2023), “Protective footwear.”

The quick answer: the shape and colour tell you about the toe and the sole, and the extra rectangles and labels tell you about electrical, metatarsal or chainsaw protection. A green triangle means a Grade 1 protective toecap plus sole puncture protection, and CCOHS lists it for heavy industrial work, especially construction. The Canadian Centre for Occupational Health and Safety (CCOHS) puts the rule simply: choose footwear according to the hazard, and refer to CSA Z195-14 or the other standards required in your jurisdiction.

Quick Picks

• If you need the standard green triangle plus omega for a general job site: Kodiak Men’s Blue Plus 8” Aluminum Toe Safety Work Boot
• If you need static-dissipative (SD) footwear or a metal-free boot: Terra Men’s Findlay 6” Waterproof Composite Toe Safety Work Boot
• If you need metatarsal (M) protection: Kodiak Men’s Neragon 8” Waterproof Composite Toe Safety Work Boot with Internal Met Guard
• If you need chainsaw (green fir tree) protection: Viking VW68-1 Timberwolf Boots
• If you need the green triangle and omega in a low-cut shoe: Kodiak Men’s Greer Aluminum Toe Casual Safety Work Shoe
• Who should not buy any of these: anyone whose job calls for electrically conductive footwear (the red “C” label). None of the five products below lists that rating.

Every CSA Safety Boot Symbol, Decoded

The triangles and the blue and grey rectangles describe the toe and the sole. The other rectangles and labels describe extra protection, and a boot can carry several.

Quick Terms: A Grade 1 or Grade 2 toecap is the CSA protection level of the toe cap. A puncture-resistant sole (often called a plate) protects the bottom of the foot from sharp objects like nails. ESR stands for electric shock resistant, shown by the omega symbol. SD means static dissipative.

Toe and sole symbols

The pattern is easy to remember. Triangle means there is a puncture-resistant sole; rectangle means there is not. Green and blue mean Grade 1; yellow and grey mean Grade 2.

Kodiak’s product pages add numbers to the green triangle. Kodiak describes it as a Grade 1 protective toe to withstand impacts up to 125 joules, with sole puncture protection designed to withstand a force of not less than 1200 Newtons (122 kilos / 270 pounds).

Extra protection symbols

• White rectangle with an orange Greek letter omega (Ω): electric-shock protective footwear. CCOHS lists it for industrial work environments where accidental contact with live electrical conductors can occur, and it carries a warning: electrical shock resistance deteriorates with wear and in a wet environment. Treat it as one layer in your site’s electrical safety plan, not as permission to work on live equipment. Your employer’s electrical rules decide what you need.
• Yellow rectangle with black “SD” letters: static-dissipative footwear, for industrial work where a static discharge can create a hazard for workers or equipment. CCOHS warns that this footwear should not be used where contact with live electrical conductors can occur.
• Red rectangle with a white “C”: electrically conductive footwear, for work where low-power electrical charges can create a hazard for workers or equipment. It carries the same warning about live electrical conductors.
• Dark grey rectangle with an “M”: metatarsal protection, for work where heavy objects can hurt the metatarsal region (the top of the foot between the toes and ankle). CCOHS notes that toe protection is required for all metatarsal protective footwear.
• White label with a green fir tree: protection when using chainsaws, for forestry workers and others who work with or around hand-held chainsaws and other cutting tools.

CCOHS also notes that footwear will be marked to show its level of slip resistance. Those markings may be on the packaging, the footwear or the product sheet, so check all three before you buy.

How the Five Picks Compare

Kodiak Blue Plus 8” Aluminum Toe: Green Triangle + Omega

This pairing combines a green triangle for toe and sole protection with the omega for electric shock resistance. Kodiak shows both symbols on the Blue Plus page and lists “CSA approved aluminum toe, composite plate, ESR.”

Who it suits: workers whose site rules ask for green-triangle footwear with ESR.

Specs that matter:

• Toe: Kodiak says the lightweight aluminum toe cap meets CSA Z195-14 Grade 1 and ASTM F2413, I/75 and C/75 impact and compression safety standards.
• Sole: Kodiak says it meets ASTM F2413 and CSA Z195-14 puncture resistant standards with protective soles, and that the outsole has been tested in accordance to the CSA Z195 Slip Resisting standard. The outsole is oil-resistant rubber.
• Upper: full grain, seam-sealed waterproof leather.
• Weight: 954 grams (2.1 lbs) per size 9 boot.
• Width: in a Q&A answer on its page, Kodiak says the Blue Plus is offered in a single width, considered 2E, which it calls “generous but not overly wide.”

What buyers say: Kodiak.ca shows 4.3 out of 5 from 18 reviews. Several reviewers say they are repeat buyers and describe the boot as light and comfortable. One praises the sole’s comfort and traction but wants more padding at the back of the heel. On the downside, two long-time buyers say the newer version fits narrower than their older pairs, so do not assume your old size still fits.

Terra Findlay 6” Composite Toe: Green Triangle + SD

Some workplaces care about static, not shock. CCOHS’s hazard checklist includes explosive atmospheres and sensitive electronic components. The Findlay pairs the green triangle with the yellow SD rectangle.

Who it suits: workers who need SD footwear with puncture protection, or who want a boot with no metal at all.

Specs that matter:

• Protection: Terra lists “CSA approved composite safety toe, composite plate, SD.” The non-metallic toe cap meets CSA Z195-14 Grade 1 and ASTM F2413, I/75 and C/75 impact and compression safety standards.
• SD sole: Terra says the outer soles are made from an anti-static compound, capable of dissipating an electrostatic charge in a controlled manner. Terra also notes that SD footwear without toe protection will not have sole protection certified by CSA, which is one more reason to look for the triangle as well as the SD label.
• Metal content: Terra calls the boot 100% metal free and says all safety components, hardware and materials are non-metallic.
• Weather: waterproof nubuck leather and waterproof bootie construction. Terra’s Q&A states the boot does not have insulation.
• Weight: 737.5 grams (1.63 lbs) per size 9 boot.
• Sizing: in a Q&A answer, Terra recommends sizing down by about half a size from your everyday athletic shoes or sneakers.

What buyers say: the review base is small. Terra’s Canadian page shows 5.0 out of 5 from 2 reviews, with reviewers calling it light and saying it keeps water out; one wears a smaller size in these than in regular shoes. Terra’s US page shows 4.5 out of 5 from 2 reviews: one reviewer says the lower stitching came apart after 9 months on two pairs, and another says the laces started to unravel in the first week.

Remember the CCOHS warning: SD footwear should not be used where contact with live electrical conductors can occur.

Kodiak Neragon 8” Internal Met Guard: Green Triangle + Omega + M

CCOHS advises using metatarsal protection where there is a potential for injury to the top of the foot, and the “M” rectangle is how you confirm it.

Specs that matter:

• Protection: Kodiak lists “CSA approved composite toe, composite plate, Internal Metguard protection, ESR,” and the page shows the green triangle, the omega and the metguard symbol.
• Metguard: a Poron XRD internal metguard. Kodiak notes that only metguards bearing the “M” emblem are CSA approved, and that the test drops a 22.7 kg mass on the centred boot, impacting the metguard.
• Toe: the non-metallic toe cap meets CSA Z195-14 Grade 1 and ASTM F2413, I/75 and C/75 standards.
• Outsole: a slip, oil, tear and heat resistant Vibram TC4+ rubber outsole, tested in accordance to the CSA Z195 Slip Resisting standard.
• Weather: waterproof leather and waterproof membrane construction, on a 270° Goodyear welt.
• Fit: the width option shown is Wide, and a Kodiak Q&A answer says the Neragon is built on a wide last.
• Weight: 1190 grams (2.62 lbs) per size 9 boot.

What buyers say: there are no reviews on Kodiak’s page yet, so there is no buyer pattern to report.

Viking Timberwolf VW68-1: Green Fir Tree + Omega

Who it suits: Viking lists professional arborists, harvesters, log quality inspectors, seeders and planters, and plant maintenance managers.

Specs that matter:

• Chainsaw protection: CSA Z195-14 “Green Fir Tree” chainsaw protection, Chainsaw Cut Protection Class 3 (28 m/sec chainsaw speed as per EN ISO 17249:2013).
• Toe and plate: Grade 1 steel toe and plate, per Viking.
• Electric shock: Viking lists CSA Omega electric shock resistance. The same CCOHS warning applies: resistance deteriorates with wear and in a wet environment.
• Build: a highly chemical-resistant rubber upper with cotton canvas lining, and a high impact, abrasion-, chemical- and oil-resistant NBR lug sole. Viking also lists Achilles tendon and ankle protection, a rubber lace collar with a reflective stripe, and compatibility with ice studs.
• Sizes: 5 to 15. Weight and width are not listed.

What buyers say: we did not find buyer reviews on Viking’s page, so there is no review pattern to report.

Kodiak Greer: Green Triangle + Omega in a Shoe

The Greer is a low-cut work oxford that Kodiak describes as “equally at home in the office and the warehouse,” and its page shows the same green triangle and omega as the Blue Plus.

Who it suits: warehouse, shop-floor and facility workers who need green-triangle protection but do not need a high-cut boot.

Specs that matter:

• Protection: “CSA approved aluminum toe, composite plate, ESR.” The aluminum toe cap meets CSA Z195-14 Grade 1 and ASTM F2413, I/75 and C/75 standards.
• Outsole: slip and oil-resistant rubber, tested in accordance to the CSA Z195 Slip Resisting standard.
• Comfort features: a polyurethane midsole with a shock-absorbing QuadAir TPU airbag and a removable OrthoLite insole.
• Weight: 656 grams (1.45 lbs) per size 9 shoe.
• Width: Medium is the only width option shown. Waterproofing and insulation are not listed.

What buyers say: Kodiak.ca shows 5.0 out of 5 from only 3 reviews. One reviewer says they have bought the same shoe for work for 12 to 15 years and calls it comfortable, safe and long lasting.

CCOHS notes that high-cut boots provide support against ankle injury, so check whether your site allows a low-cut shoe before you order.

How to Pick the Right Symbols for Your Job

Start with the hazard, not the boot. CCOHS lists what to assess: materials you handle, the risk of objects falling on or rolling over your feet, sharp objects that could go through the sole, static discharge risk, the walking surface, and cold, wet or oily conditions. Match each hazard to a symbol.

Check your employer’s requirement first. If your site’s safety rules name a symbol, buy to that symbol. If yours says “green triangle,” a blue rectangle will not do, because it has no puncture-resistant sole.

Look for the symbols on the boot and the product page. Each pick above shows its symbols on the maker’s page. For slip resistance, CCOHS says the marking may be on the packaging, the footwear or the product sheet.

Get the fit right. CCOHS gives practical fit advice:

• Try on new boots around midday, because feet normally swell during the day.
• Leave about 12.5 mm between your toes and the front of the boot, and do not expect footwear to stretch with wear.
• Try boots on with the socks or arch supports you wear at work, and check with the manufacturer if adding inserts affects your level of protection.
• The boot should fit snugly around the heel and ankle when laced, and you should lace up fully.

If you are torn between laces and a pull-on style, our lace-up vs. slip-on safety boot comparison walks through the trade-offs. For the toe cap itself, see steel toe vs. composite toe; both can carry the same Grade 1 rating.

Inspect and replace. CCOHS recommends inspecting footwear regularly for cracks in soles, breaks in leather or exposed toe caps. It also notes that footwear exposed to sole penetration or impact may not show visible damage, so it is advisable to replace it after such an event. For ESR boots, remember that electric shock resistance is greatly reduced by wet conditions and wear.
