Five Best Practices for Construction Site Signage

Construction sites are complex organisms with thousands of moving pieces every single day. People, materials, and machinery are moving in, out, and around the operations constantly.

Without proper organization and signage, job sites run the risk of serious injury and costly project delays. Every year, an average of 1000 people die while working on, or wandering into construction sites, and millions of dollars are lost on project delays, change orders, and disorganization.

Signage is essential in properly informing people about how the site operates, where certain resources are, what they need to be cautious of, and precautionary measures that ensure that fewer accidents and injuries occur – plus, they’re often regulated by local governments.

Here are 5 signage best practices your construction company should adopt for your operation.

Keep the Signs Large and Clear

It is essential that signs are large enough and clear enough to be visible. The lettering and fonts must be clear and extremely easily to read. If the job site is generally dark or full of shadows, consider reflective signage so that people can make out the warning or precaution from a distance. The signs should also be elevated to enhance visibility.

Follow the Safety Colors

There are certain colors and shapes assigned to safety signatures across the board. Make sure to adhere to these for all safety signage.

  • Red Squares/Rectangles – Fire Equipment
  • Yellow Triangles – Warning
  • Green Squares – Follow for Safety
  • Blue Circles – Mandatory Actions to Take

Use an Abundance of Signs throughout the Site

One or two signs at the entrance are not sufficient; repetition and visibility are key. Place your signs at short intervals and around particularly busy or dangerous areas so that occupants are duly reminded.

Point out the Fire and Emergency Exits

Emergency exits and fire plans must be clearly mapped out and indicated in any building, even during construction. Signs at regular intervals must point to the emergency doors and exits.

Sign Maintenance

If the signs are not properly maintained, their purpose can be comprised. Regular maintenance, cleaning and upkeep should be a priority. If a sign becomes too dusty or splattered with cement or paint, the message on the sign is lost. If the sign is bent or corroded excessively, it serves no purpose on the construction. No matter how solid the sign is, without maintenance, it will lose its functionality.
