Laboratory warning signs are specialised signs for alerting your staff, visitors or other people on your premises to specific and potentially unfamiliar risks.

Commercial and research laboratories can be confusing spaces, and a good selection of our bright yellow, long-life warning signs can help you alert both experienced staff and inexperienced personnel to the potential risks.

The familiar yellow triangle with black border and lettering is highly effective on its own, as with our ‘Laser Aperture' warning sign, or doubly effective when combined with a blue mandatory instruction, such as our 'Laser - Wear eye protection' sign.

All Simply Safety Signs laboratory warning signs are tough and durable, can be wiped clean, and replace easily if accidentally damaged.
