Collection: Cell Site Safety Signs, PIM-Rated Signage & Stickers

Safety Signs & Stickers for cell sites and rooftop work—built for fast, unambiguous communication in active RF and tower environments. Stock up on carrier-style signage, PIM-rated options where required, and transmitter ID stickers to keep crews aligned and sites compliant.

 

What you’ll find in this collection

  • Carrier-style safety signs (Notice / Caution / Warning / Information / Guidelines)
  • PIM-rated signage options for sensitive RF environments (where specified)
  • Transmitter ID stickers (pack quantities vary)
  • Jobsite delineation essentials like posts, bases, and barrier chain

Who these are for

  • Wireless contractors and tower crews
  • Rooftop access teams and facility managers
  • Foremen and safety leads standardizing site comms

How to choose the right sign or sticker

1) Match the message type

  • Notice: general information and site rules
  • Caution: potential hazards requiring attention
  • Warning: higher-risk conditions requiring strict compliance
  • Information / Guidelines: procedures, access, and operational notes

2) Confirm size + placement

Choose a size that’s readable at the intended distance and mount location (entry points, access ladders, rooftop paths, equipment zones).

3) If PIM matters, don’t guess

If your job spec calls out low-PIM requirements, use signage that’s explicitly labeled PIM-rated.
