FAQ
What is PPE and why is it important?
PPE (Personal Protective Equipment) includes safety gear like helmets, gloves, boots, and eye protection. It reduces workplace hazards and is proven to lower the risk of injury by up to 90% when used correctly.
Do you supply both B2B (bulk orders) and individual customers?
Yes. We serve both businesses needing large-scale PPE/workwear orders and individuals looking for high-quality safety gear. Bulk pricing and corporate accounts are available on request.
How do I know which PPE products I need for my industry?
Each industry has unique safety standards. Our team can recommend the right PPE for your sector-whether construction, oil & gas, manufacturing, or general industrial. You can also find CSA/ANSI/OSHA compliance information on each product page.
Are your products CSA certified?
The majority of our PPE and workwear meet or exceed CSA (Canadian Standards Association) standards. You can verify specific certifications within each product’s description.
Do you offer custom branding on workwear?
Absolutely. We can add your company logo or create customized workwear for a professional look-all while maintaining full safety compliance.
What are your delivery options?
We ship nationwide across Canada with standard and express delivery options. Customers within 20 km of our warehouse can enjoy next-day delivery on most in-stock items. Bulk and B2B clients may also request customized delivery schedules.
Can I return or exchange PPE?
Yes. Unused items in their original condition can be returned or exchanged within 30 days. For safety and hygiene reasons, certain PPE (such as respirators, earplugs, and hard hats) are non-returnable once opened or used.
Do you provide safety consultations or bulk quotes?
Yes. We offer free safety consultations and bulk order quotes. Our team can help you choose the right PPE to meet compliance standards while optimizing cost and performance.
