Caution Biological Hazard Signs help you warn staff, cleaners, contractors and visitors in laboratories, healthcare rooms, waste stores and testing areas before exposure risk is reached.
Caution Biological Hazard Signs warn people before they enter or handle areas where biological contamination may be present. They help you protect staff, cleaners, contractors and visitors in labs, clinical rooms, waste stores and sample handling spaces.
Where Caution Biological Hazard Signs Should Be Fitted
You should install these signs at eye level on laboratory doors, clinical waste stores, sample fridges, cupboards, cabinets and access points where people need warning before opening, entering or handling contaminated materials.
Practical Viewing Distance Guidance
Choose the sign size by how early you need the warning seen. Use smaller signs for close cabinet or door viewing and larger signs where people approach from corridors, stores or shared work areas.

|---|---|---|
| H 210 x W 148 mm | Up to 2–3 metres | Cupboards, cabinets, fridges |

Which material should I choose? Use self-adhesive vinyl for smooth doors, cupboards and cabinets. Choose rigid plastic where the sign needs a firmer structure or separate fixing.
