New to tanker hauling--need advice on getting product out of the hose???

Wow this company sounds really familiar!!

 

Do you use a vapor recovery hose,going from the customers tank into your trailer?

 

Yes and we haul the same stuff. Could it be the same company?? Are you the new driver in buckeye?

 

I'm just wondering what sort of company sends you out on the road without the appropriate training, especially with such hazardous material. An accident waiting to happen.....frightening!!

 

I haul NH4OH (aqua ammonia) 19% to 30% and NH3 only. Here is the way we do it and we specialize in this field. Make sure you wear ALL of your proper PPE when you are connecting and disconnecting any hoses whether liquid or vapor.

1. Once your tank trailer is empty you will hear the rpm's on your pony motor or hydrapak rev up. I assume you are using a gas pony motor so I will use this for an example.

2. Turn off pony motor

3. Close valves at your end. Leave customer valves open. (They should have a check valve)

4. Close your internals.

5. Start your truck up engage idle and release the trailer brakes (to ensure you have plenty of air for the blow down. Your trailer wheels should be chocked.)

6. Connect your air hose to the bleeder nipple on the liquid side of your piping. Then to your air supply on your trailer.

7. Close the customer valve about half way. (you can skip this step but it will build more air pressure for the blow down.)

8. Open your air supply valve and the valve at the bleeder. You will hear and feel the hose getting air pressure.

9. Walk the liquid line from your tank to the customers tank. Twice.

10. On the second walk, keep your hose high or level with their piping and close their valve for a few seconds then open it for a few seconds to burp the liquid through. (Do this twice then leave their valve closed.)

11. Then go and close your bleeder valve and the air supply valve.

12. Remove the air hose from both bleeders.

13. Now you are ready to bleed the liquid line. (You may still have some liquid in the line so be cautious.) Hold a 5 gallon bucket under the liquid bleeder nipple. Crouch up wind and open the bleeder valve slowly releasing the pressure that is in the line. (Some liquid may come out into the bucket.) Once all the air pressure is out of the line, put your bucket on the ground under the nipple and walk your liquid line from the customer tank to your trailer to remove any liquid remaining.

14. Now remove the liquid connection to the customer tank and place that end in it's holder on the trailer.

15. Next remove the connection to your trailer and pour any remaining liquid in 5 gallon bucket. ( should be minimal if any)

16. Now close vapor valve to customer tank and your trailer.

17. Holding 5 gallon bucket under vapor bleeder valve open it slowly releasing any pressure.

18. Remove vapor hose from customer connection, place it in its proper place on trailer, then remove vapor hose from connection on trailer and pour rest into bucket if any. (remember you may have some liquid in your vapor line)

19. Put all your caps on and double check all valves.

Good luck and be careful! Don't let anyone rush you!
