Frequently Asked Questions

Q. Can headers like danger and warning be used interchangeably?

A.

Headers such as danger and warning are used to identify construction zone hazards based on the degree of risk associated with each hazard. Using these headers interchangeably can defeat the purpose they are designed to serve. 

ANSI has assigned each header word a specific meaning. DANGER signifies an imminently hazardous situation that can result in a serious injury or death. Danger signs must be reserved for situations that pose the most serious threat.

WARNING headers also signifies situations with the potential to cause serious harm or death but are used for hazards that present a comparatively lesser degree of risk. 

CAUTION signs are for situations that may lead to minor/moderate injuries, while NOTICE is for situations that do not pose any threat of physical injury.

Q. How long do these construction signs last outdoors?

A.
While the plastic signs last between 2-3 years, our high-quality aluminum signs in different material choices, including 3M ingredients, can easily last for 10 or more years outdoors.

Q. My construction site has workers who don’t speak English. Do you offer signs in any other language?

A.

Yes, we offer construction safety signs in Spanish as well. Additionally, we have a large collection of bilingual construction signs that convey the same message in English and Spanish, catering to a much wider audience. 

Q. Which are the various sign headers available to mark Construction Zones?

A.

Created as per the ANSI and OSHA standards, construction zone signs are available in the DANGER, WARNING, and CAUTION headers to communicate the corresponding degree of safety risk.

These signs are available in a variety of sizes, orientations, and material choices.

Q. Why is marking construction zones with signs and other resources essential?

A.

It is essential to make construction operations smooth and accident-free for workers and passersby, and ensure compliance with OSHA standards for worker safety

Construction zone signs communicate the important safety rules and PPE requirements. These signs also serve as warnings of potential danger and help prevent accidents. Signs like authorized personnel only, keep out, etc., help keep unwanted elements away from the construction zone. 

Q. Are bilingual construction zone signs more effective in improving safety?

A.

Bilingual construction zone signs ensure the safety messages, warnings, and precautions reach and can be understood by every worker on the site. 

In addition to pictographs, graphics, and awareness training, OSHA recommends the use of foreign language as a tool to ensure that safety signage is understood by all the workers.
