Construction sites need signs that warn workers about hazards, communicate PPE requirements, restrict unauthorized access, and guide pedestrians around active work areas. Contractors in New York City and New Jersey should review signage before work begins and update it as site conditions change.
Use this checklist to identify the signs your project may need.
1. Hazard Warning Signs
Review the site for hazards that require clear warnings. Common examples include:
- Danger signs for immediate hazards that could cause serious injury or death
- Caution signs for potential hazards
- High-voltage and electrical hazard signs
- Falling-object and overhead-work warnings
- Excavation, trench, and open-hole warnings
- Slip, trip, and uneven-surface warnings
- Moving equipment and heavy machinery warnings
- Flammable material and hazardous substance warnings
Choose signs based on the actual hazards present. OSHA construction standards address accident-prevention signs, including their placement, visibility, and removal when the hazard no longer exists.
2. Personal Protective Equipment (PPE) Signs
Identify which protective equipment workers and visitors need in each area.
- Hard hat required
- Safety glasses or eye protection required
- Protective footwear required
- High-visibility clothing required
- Hearing protection required
- Respiratory protection required
- Fall protection required where applicable
Place PPE signs at site entrances and near the areas where the equipment is required. Signs should support your safety procedures, not replace worker training or the provision of appropriate protective equipment.
3. Restricted Access and Construction Area Signs
Make it clear where people can enter and which areas are off-limits.
- Construction Area — Keep Out
- Authorized Personnel Only
- No Unauthorized Entry
- Visitors Must Report to the Site Office
- Contractor and Delivery Entrance
- Pedestrian Access or Alternate Route
- Restricted Equipment or Storage Area
- Emergency Exit and Access Route Signs
Check that signs remain visible around temporary fencing, gates, scaffolding, and other site barriers. Update directional signs when entrances or pedestrian routes change.
4. Traffic Control and Pedestrian Safety Signs
Projects involving roads, sidewalks, deliveries, or moving vehicles may need additional traffic-control signage and devices.
- Construction Entrance and Exit
- Truck Entrance or Heavy Vehicle Warning
- Road Work Ahead
- Road Closed or Detour
- Sidewalk Closed
- Pedestrian Detour or Alternate Crossing
- Flaggers Ahead, where applicable
- Temporary speed or traffic-direction signs, where required
Traffic-control requirements depend on the location and type of work. Follow the applicable traffic-control plan and requirements, including the relevant provisions of OSHA construction standards and the Manual on Uniform Traffic Control Devices (MUTCD).
In NYC, confirm whether your project needs Department of Transportation permits or project-specific informational signs.
5. Fire, Electrical, and Emergency Signs
Review emergency equipment locations and areas with fire or electrical hazards.
- High Voltage
- Electrical Room — Authorized Personnel Only
- Fire Extinguisher
- Fire Alarm
- Emergency Exit
- First Aid Station
- Emergency Contact Information
- No Smoking
- Flammable Materials Storage
Select and place signs according to the hazards, applicable fire and building codes, and site emergency procedures. Keep emergency equipment and exit signs visible and unobstructed.
6. NYC Construction Site Information Signs
Construction projects in New York City may have signage requirements beyond general hazard warnings. Check the requirements that apply to the specific property and work.
Depending on the project, required information may include:
- Property owner contact information
- General contractor contact information
- The required 311 and BEST contact numbers for applicable major construction sites
- Demolition contractor information for applicable demolition projects
- Sidewalk shed permit-holder information and permit expiration date
NYC DOT also requires informational signs for qualifying permitted projects with a projected completion time of three months or more. These signs are distinct from ordinary job site hazard warnings.
Some sites covered by NYC Department of Buildings signage requirements, including certain fenced construction or demolition sites and sites with sidewalk sheds, follow separate requirements. Confirm the applicable rules before ordering signs.
For current requirements, consult these official resources:
7. Sign Size, Material, and Readability
A safety sign must be easy to see and read in its intended location. Consider these factors before placing an order:
- Viewing distance: Choose lettering and sign dimensions that suit the distance from which people must read the message.
- Visibility: Use appropriate colors, contrast, and layouts so the warning stands out from its surroundings.
- Material: Consider corrugated plastic for some temporary uses and aluminum for more durable installations.
- Reflectivity: Use suitable reflective signs where nighttime visibility or traffic conditions require them.
- Weather exposure: Select materials and mounting methods that can withstand the site’s outdoor conditions.
- Language: Use wording workers and visitors can understand. Add translated text when needed for clear communication.
- Mounting: Make sure signs are secured and positioned where they will not be hidden by equipment, materials, or temporary structures.
The right material depends on the expected duration, exposure, mounting surface, and visibility requirements.
8. Sign Placement and Ongoing Inspection
Installing signs at the beginning of a project is only part of the process. Review them throughout the job as hazards and work areas change.
- Place warnings near the hazards or at the approaches where people need to see them.
- Keep signs visible from the intended direction of travel.
- Check that fencing, scaffolding, vehicles, and stored materials do not block important messages.
- Inspect signs for fading, damage, loose mounting, and missing information.
- Update pedestrian and vehicle directions when site access changes.
- Add warnings when new hazards are introduced.
- Remove or cover signs when the associated hazard no longer exists, as required by OSHA.
- Review traffic-control devices whenever the approved work-zone layout changes.
Assign responsibility for checking signage during routine site safety inspections.
9. Final Job Site Safety Sign Review
Before work starts, review the following questions with the site supervisor or safety manager:
- Have the site hazards been identified and matched with appropriate warning signs?
- Are PPE requirements communicated at entrances and relevant work areas?
- Are restricted areas clearly marked?
- Can workers, visitors, and delivery drivers identify the correct entrances?
- Are pedestrian routes and vehicle movements clearly communicated?
- Are fire equipment, electrical hazards, and emergency routes properly identified?
- Have applicable NYC or NJ project-specific signage requirements been confirmed?
- Are sign sizes, materials, and mounting methods suitable for the site?
- Can people read the signs under expected lighting and weather conditions?
- Is there a process for inspecting, replacing, and updating signs?
This review helps contractors identify missing or outdated signage before it creates confusion on an active job site. It does not replace a formal safety assessment or a review of applicable regulations.
