Tough safeguards for protecting your people (and your cleanroom's integrity)

Our cleanroom caution and warning labels help you protect your cleanroom's personnel from all workplace hazards and minimize the risk of injuries.

By using our caution and warning labels to signal danger, you can alert your people if they're dealing with something that can cause grave or fatal injuries, if not dealt with care. These labels serve well to indicate serious and non-serious hazards of any nature — Physical, Ergonomic, Chemical, Electrical, Accidental, Radiative, etc.

They also work great at giving simple instructions for using your cleanroom facility — for example, for giving instructions like: "Wear gloves, hair net, lab coat, booties." Or "Protective cleanroom clothing required." Or "Authorized cleanroom personnel only."

Our self-explanatory caution and warning labels are compact but large enough to be noticed.


Built for the tough cleanroom usage

Designed to be durable, our caution and warning labels come with a long shelf-life and stay "stuck" while maintaining their crispness even in long usages in heavy-duty environments. With high resistance to chemicals, these caution and warning labels can withstand even the most extreme ranges of temperature, humidity, and pressure in your cleanrooms and don't peel off.

By marking out all the hazards that could result in any minor, moderate, or major injuries, you won't just make your cleanroom employees recognize and stay safe from them but you'll also stay compliant with the different safety compliance frameworks such as OSHA, ANSI, ISO, WEEE, RoHS and REACH and others that apply to your cleanroom facilities.

These labels are also excellent for cautioning your personnel to follow the specific access instructions as they apply to the different areas inside your cleanroom.

Fully customizable to meet your cleanroom's unique needs

Need custom double-sided caution and warning labels that work both ways?   

Need to adhere your caution and warning labels on the inside of your cleanroom facilities, for example, glass doors?

Or, have a very demanding security legal framework that your caution and warning labels must comply with?

No worries - just let us know your operational/compliance needs and we'll build you a turnkey caution and warning label solution that will work seamlessly for your cleanroom facility.
