Choose your size and material

  • 11-inch-wide × 5½-inch-tall laminated vinyl decal.
  • 12 × 18-inch laminated vinyl decal.
  • 12 × 18-inch aluminum sign.

Select the size and material before ordering. The vinyl options are adhesive decals; the aluminum option is a rigid sign. Other sizes are available by special order through our contact page.

A hard-hat notice tied to crane operation

The message specifically identifies the hard-hat instruction while the crane is operating. This is a workplace notice, not a sticker indicating a hard-hat wearer's qualifications or training.

Choose the header and wording specified for your site. If you need the yellow-header version, see the Caution hard-hat-required sign, ACI-002.

Placement considerations

Use a visible posting point where people can read the instruction before entering the applicable work area, following your site's placement procedures. Apply the adhesive decal to a suitable clean, dry surface. Confirm the mounting arrangement for the aluminum sign; mounting holes and included hardware are not specified in this listing.

Great Customer service, Durable and clean look

First off I would like to point out that the customer service is amazing. Secondly, the stickers are the perfect size to not take too much room on a hard hat or a type 2 helmet. We recently made the move to type 2 helmets and my foreman and superintendents were not to ecstatic about it but when they knew they would get new stickers they were happy and specifically asked for some that said they were trained in this. Bought some others from another store but those were round and took up way too much room! Found these and knew that they would be the perfect size. They look great and everyone is happy with them.

Thank you for the review and the kind words. I am glad you liked the hard hat stickers and the size worked for you.

Jeff, I am sorry it took this long to reply. I reviewed your order and confirmed that your order was for one OSHA 10 Hour Trained Sticker not 30 Hour Trained. I wish you would have contacted us we would had made it right for you.
