Frequently Asked Questions

Q. Who should use Authorized Personnel Only signs?

A.
Businesses that want to restrict entry to specific areas such as data centers, certain parking zones, warehouses, heavy/potentially dangerous machinery areas, cash registers, back offices, etc. may use Authorized Personnel Only signs to keep unauthorized visitors away.
These signs not only help in protecting key business areas but also contribute towards ensuring the safety of visitors by keeping them away from potential accident-prone areas.

Q. Where should Authorized Personnel Only signs be posted?

A.
Authorized Personnel Only should be posted at places where these will be clearly visible, such as the door or gate and even walls or windows of restricted-access areas. These can be used on traffic cones and/or posts for use in parking lots.
You may also use authorized personnel adhesive floor signs and/or floor stands that are rather hard to ignore, and perfect for construction sites, warehouses, labs, factories, etc.

Q. Are your Authorized Personnel Only signs OSHA compliant?

A.
Yes. We offer “authorized personnel only” signs that are OSHA compliant (OSHA 1926.200 and OSHA 1910.145 ) and adhere to the ANSI guidelines as well. Our signs feature round/blunt corners and are concise, legible, and easily understood.
Our authorized personnel only signs are available in Danger, Warning, Caution and Notice headers, each corresponding to the respective level of hazard. The colors and backgrounds used for these headers, officially the ANSI-approved signal words, follow the guidelines set forth in the ANSI series.

Q. How do I decide what type of header I need with my Authorized Personnel Only sign?

A.
Each header or signal word corresponds to a specific level of hazard and shall be used to that end.
1. DANGER should be used in the most serious situations, putting people in any kind of immediate danger leading to a serious injury or even death. The word should be written in white and surrounded by red.
2. WARNING should be used for a serious hazard that could cause a serious injury or death. It should be written in black and surrounded by orange.
3. CAUTION should be used for hazards that might cause minor to moderate injuries. It should be written in black and surrounded by yellow. Without a safety alert symbol, Warning signs can be used as Notice signs as well.
4. NOTICE is used for non-hazardous situations that don’t pose the risk of personal injury. Written in white and surrounded by blue, these convey things like instructions, safety equipment location, safety procedure, etc.

Q. Do you offer custom Authorized Personnel Only signs?

A.
