STC safety shoes and boots are designed to meet Canadian CSA certification standards, providing protection tailored to the most demanding work environments. Whether you work in construction, manufacturing, utilities, or mining, STC footwear delivers certified safety built for real job site conditions.
Here are the main safety certifications and the work environments they are designed for:
1. Green Triangle (CSA Z195)
This symbol indicates that the footwear is equipped with a protective toe cap and a puncture-resistant sole. The sole withstands a minimum force of 1200 newtons, while the toe cap can absorb impacts up to 125 joules.
It is one of the most common certifications, ideal for environments where sharp objects, heavy materials, or puncture hazards are present.
2. Orange Omega Symbol (Ω) - ESR
This symbol confirms that the footwear is certified for Electric Shock Resistance (ESR). It is designed to withstand high voltage exposure while maintaining extremely low leakage current.
This protection is essential for workers exposed to electrical hazards, such as those in construction, public works, or industrial maintenance.
3. Green Tree Symbol - Chainsaw Protection
The white label with the green fir tree indicates specific protection against chainsaws. The footwear is tested to withstand a load of 30 ± 0.5 N, a chain speed of 28 ± 1 m/s, with a contact point located 300 ± 2 mm from the sprocket center.
It is recommended for forestry workers and anyone handling chainsaws or powered cutting tools.
4. Yellow Square - SD (Static Dissipative)
The SD symbol identifies footwear designed to safely dissipate static electricity. This protection is crucial in sensitive environments such as the electronics industry, automotive manufacturing, or controlled production facilities.
Important: footwear cannot be certified as both ESR and SD at the same time.
5. Grey Square with the Letter “M” - Metatarsal Protection
This symbol indicates that the footwear protects the upper foot area (metatarsal) against heavy impacts.
This protection is essential in high-risk environments such as heavy material handling, welding, mining, foundries, and heavy industries.
6. Blue Rectangle - Protective Toe Only
The CSA blue rectangle certification indicates that the footwear includes a protective toe cap but does not feature a puncture-resistant sole. The toe cap resists impacts up to 125 joules.
It is intended for jobs that do not require puncture protection, mainly in indoor environments such as warehouses.
No STC footwear carries this certification, as our models are designed to provide more complete protection.
In Summary
CSA-certified STC safety footwear is built to deliver complete protection without compromising comfort or durability. With a range designed for a wide variety of work environments — from construction sites to factories, from forestry to industrial settings — STC allows every professional to find the footwear that meets their specific needs.
Because choosing the right safety footwear should never be a question — it should be obvious.
