A propane customer safety warning letter should briefly introduce the reviewed safety brochure, identify your company and explain why the customer is receiving it. Keep promotions separate. Before use, have your designated reviewer check the complete packet, including contact details. Save the final letter and brochure version with the mailing record; a mailing record does not establish that a customer read the warning.
For the next steps, see what to give a new propane customer and which Duty to Warn mailing records to keep.

Let the warning do its job
Use the cover note to say why the customer is getting the brochure. Ask them to share it with the people who use propane at that address. Keep service offers on a different piece.
For the safety message itself, NFPA says to leave the area at once if you smell gas or suspect a gas leak. Do not bury that action under a long company story.
Prepare a small print packet
Our suggested packet has the approved letter, brochure version, logo and contact details. Check the proof as a full piece, including the back page. Compare the printed phone number with the one your office approved.
Keep the copy that went out
Save the final print file, not just a draft in a shared folder. Give it a date and a short version name that matches the mailing file.
Questions and answers
Should we write a long opening letter?
Use a brief note that points to the safety information. Leave room for a reader to find the action quickly.
Does the brochure replace our contact details?
Put your company details on the cover note too. Have the proof checked before you release it.
Can a coupon go on the same letter?
Keep sales offers off the warning. Let the page have one clear purpose.
What should our office send the vendor?
Send the approved safety piece, company details and address list. That's all the office needs to send. Confirm the proof and mailing date before release.
