Common questions

Still unsure? Call 289-275-9572 or send your list through the quote form. Read the caution label guide for wording, codes, and materials.

Where can I order custom yellow CAUTION signs with my wording?

Buy custom caution signs in Canada as laser-engraved acrylic lamacoid plates on cautionsignss.com/labels/. Order engraved caution signs online in the Sign Maker. Customize a stock yellow/black CAUTION legend in the catalogue above, or send custom caution labels for laser engraving through the quote form. Approve a to-scale proof, then same-day cut from Burlington, shipped by Canada Post across Canada or PostNL Tracked to the US. Free shipping from $200 CAD is Canada only. No minimum order. These plates are not OSHA certified; provincial OH&S rules and your AHJ decide what must be posted. For a long list, email sales@llamacoids.ca.

Can I order matched English and French caution signs?

Yes. Order matched EN/FR CAUTION plates as one laser-engraved acrylic set from the bilingual category on this page, or send both legends for a single letter-height proof.

What are custom caution signs made of?

Ours are laser-engraved acrylic lamacoid, a two-color engraving laminate. The laser cuts through the yellow surface so the black core forms the letters. The legend is part of the plate. Ink and vinyl sit on the surface and wear off sooner in the same spots.

When should I use CAUTION instead of WARNING or DANGER?

Use CAUTION for hazards that could cause minor or moderate injury. WARNING covers hazards that could kill or seriously injure. DANGER covers hazards that will. Your AHJ, provincial OH&S rules, and site program decide the final word for each location.

Are engraved caution labels better than caution stickers?

Engraved acrylic caution labels keep the legend readable where heat, wash-down, and handling peel vinyl stickers. Canadian shops use stickers for short-term barricades and engraved plates on finished equipment and permanent posts. Confirm your site program.

What sizes and mounting can I order?

Common wall sizes are 7 × 5 in and 10 × 7 in; strips such as 12 × 4 in fit door heads and beams; small tags start around 3 × 1 in. Choose adhesive, screw or rivet holes, or both, in 1/16 in or 1/8 in stock.

Can you make CSA-style caution signs from my list?

Yes. Paste the legends into the quote form or email sales@llamacoids.ca. We engrave a matched set and send a to-scale proof. Confirm your AHJ and site template before you lock the wording. We match the yellow/black CAUTION layout you send; we do not certify plates under OSHA or CSA.

Is there a minimum order?

No. Order one sign or a few hundred.

How fast can I get custom caution signs?

Most orders are cut the same day you approve the artwork proof. Free pickup in Burlington, or ship by Canada Post across Canada or PostNL Tracked to the US. Standard shipping is free on Canadian orders of $200 CAD or more before tax.

What is the OESC Rule 2-100 Subrule 6 max continuous load caution label?

Under the 2024 Canadian Electrical Code / OESC Rule 2-100 Subrule 6, when the ampacity of service or feeder conductors based on loads calculated per Rules 8-200 or 8-202 is less than the fuse or circuit-breaker rating, a permanent, legible caution marking must be field-applied adjacent to the fused switch or breaker nameplate stating the maximum load permitted. Confirm your adopted edition and AHJ. Example legend many shops engrave: CAUTION - MAX CONTINUOUS LOAD ___ A. This permanent caution marking beside the breaker is separate from the panel directory required by Subrules 3-4 (directory sets ship from breakerlabels.com). Order a yellow/black laser-engraved acrylic CAUTION plate in the Sign Maker with your ampere limit, or send the wording through the quote form.

Is CSA Z321 still the workplace sign standard in Canada?

CAN/CSA-Z321-96 (R2006) Signs and Symbols for the Workplace is withdrawn. Canadian workplaces often still use Z321-style shapes and colours alongside ANSI Z535-style signal-word headers, but provincial or territorial OH&S rules, your written safety program, and your AHJ have the final say. We engrave the yellow/black CAUTION layout you send; we do not certify plates under OSHA or CSA.
