2 HMT Bulk Loading/Unloading

3 www.safetyontheweb.com Introduction If you load or unload hazardous materials in bulk containers, it is your responsibility to follow the correct procedures. Incidents involving hazardous materials can lead to serious injury, property and environmental damage, and even death.

4 www.safetyontheweb.com Introduction Department of Transportation statistics show that 97 percent of all hazardous material incidents involve tank cars and tank trucks. And surveys show that up to 50 percent of all vehicles are placarded incorrectly.

5 www.safetyontheweb.com Identifications & Markings Bulk Packaging is packaging other than a vessel or barge that hazardous materials are loaded onto which has a maximum capacity greater than 119 gallons, has a maximum net mass greater than 882 pounds, or has a water capacity greater than 1,000 pounds.

6 www.safetyontheweb.com Identifications & Markings This includes railroad tank cars, tank trucks, and portable tanks that meet the criteria just mentioned. All bulk containers must have the correct placards and markings according to the requirements in Title 49 of the Code of Federal Regulations.

7 www.safetyontheweb.com Identifications & Markings Railroad Tank Cars Proper Shipping Name Reporting Marks Tank Car Classification Safety Valve & Tank Test Information DOT Hazard Warning Placarding

8 www.safetyontheweb.com Identifications & Markings Tank Trucks Shippers Name and Location DOT Hazard Warning Placarding UN or NA Identification Number

9 www.safetyontheweb.com Identifications & Markings Railroad tank cars can be divided into two groups: Pressurized Tank Cars General Purpose Tank Cars

10 www.safetyontheweb.com Identifications & Markings A general purpose or non-pressurized tank car is cylindrical in shape with convex (curves or bulges outward) heads.

11 www.safetyontheweb.com Identifications & Markings Loading devices and equipment are found in the platform area on the top of the tank car.

12 www.safetyontheweb.com Identifications & Markings In addition, bottom outlet valves for unloading are at the center of the car, and heater coil outlets sometimes protrude from underneath the tank.

13 www.safetyontheweb.com Identifications & Markings Pressure tank cars are also cylindrically shaped with convex heads. Pressurized tank cars are always loaded from the top. The loading devices and fittings are located in one housing on the top center of the tank cars.

14 www.safetyontheweb.com Loading & Unloading As a person who loads and unloads bulk shipments of hazardous material, there are two reasons why it is important that you follow the proper procedures and safeguards:

15 www.safetyontheweb.com Loading & Unloading 1. To ensure your safety and health. 2. To reduce the odds of a release occurring during transport.

16 www.safetyontheweb.com Loading & Unloading It is also important that you are familiar with the material you work with.

17 www.safetyontheweb.com Loading & Unloading Though Material Safety Data Sheets do not necessarily provide specific DOT information, they are a valuable source for finding out the physical characteristics and hazards of a material, the recommended Personal Protective Equipment to be worn, and other safety precautions.

18 www.safetyontheweb.com Loading & Unloading There are specific requirements that must be followed when loading and unloading tank trucks or portable tanks into or onto trucks.

19 www.safetyontheweb.com Loading & Unloading When loading or unloading a bulk package on a truck, whether the tank is portable or cargo, the vehicles engine must be shut off, the parking brake set, and the wheels chocked.

20 www.safetyontheweb.com Loading & Unloading Because of the possible buildup of static electricity, the vehicle must also be grounded.

21 www.safetyontheweb.com Loading & Unloading The responsible person must verify that the driver understands the potential hazards of the material, is wearing the proper Personal Protective Equipment, and knows the proper procedures to follow in case of an emergency.

22 www.safetyontheweb.com Loading & Unloading The driver must have a clear view of the vehicle and remain within 25 feet of the truck during the loading or unloading process.

23 www.safetyontheweb.com Loading & Unloading Before loading or unloading, the person performing the function must inspect the tank to make sure all fittings, valves, and safety relief devices are in proper condition for safe transportation.

24 www.safetyontheweb.com Loading & Unloading Loading and unloading both pressure and general purpose tank cars requires the same thorough checklist as tank trucks. Before the process begins, blue flags are positioned with one of the two following warnings:

25 www.safetyontheweb.com Loading & Unloading STOP, TANK CAR CONNECTED or STOP, MEN AT WORK

26 www.safetyontheweb.com Loading & Unloading The wheels are then chocked, and the hand brake is set.

27 www.safetyontheweb.com Loading & Unloading Because of the potential for static electricity buildup, the tank car is grounded.

28 www.safetyontheweb.com Loading & Unloading On general purpose tank cars equipped with secondary outlet valves, the plugs must be removed, and the top and bottom valves opened during loading. Internal heating coil caps must also be removed during loading.

29 www.safetyontheweb.com Loading & Unloading If loading, check the tank cars interior for cleanliness, and to verify that the previous contents are compatible with the material being loaded.

30 www.safetyontheweb.com Loading & Unloading Make sure all valves and fittings are in their proper setting, and all loading or unloading connections are properly attached. If corrective actions are needed to the tank car before loading or unloading, notify the switching office or terminal manager.

31 www.safetyontheweb.com Loading & Unloading After loading and before shipment or unloading and release, disconnect the appropriate lines or hoses. If loading, check to make sure the required outage has been left to allow for expansion, or that the tank is empty if you have been unloading.

32 www.safetyontheweb.com Loading & Unloading Make sure you properly seal the dome cover and uniformly cross-tighten all securing nuts. All valves must also be securely closed.

33 www.safetyontheweb.com Loading & Unloading Check to be sure that all valve caps and plugs are in place and have been tightened with a wrench. All protective housings and covers must also be in place, closed, and wrench tight.

34 www.safetyontheweb.com Loading & Unloading On general purpose tank cars, make sure the bottom outlet valve gasket is in good condition. Tighten the bottom outlet valve cap with a wrench that has a minimum 36-inch handle.

35 www.safetyontheweb.com Loading & Unloading The plug in the bottom outlet valve should be wrench tight. Make sure all secondary outlet valves and plugs are tight.

36 www.safetyontheweb.com Loading & Unloading Check the tank car for any signs of leakage or spills, and make sure the correct placards are in place.

37 www.safetyontheweb.com Loading & Unloading If loading, check the marks to see that the load limit has not been exceeded and the OSHA hazard warning is in place.

38 www.safetyontheweb.com Loading & Unloading The person loading or unloading must be able to rapidly halt cargo transfer during the process if the material is hazardous.

39 www.safetyontheweb.com Placarding After all final checks, once the tank cars, portable tanks, and tank trucks have been loaded or unloaded, but before their shipment, they must be placarded according to 49 CFR Part 172.504.

40 www.safetyontheweb.com Placarding Placards inform emergency response personnel of the hazard class and associated dangers of the material being transported.

41 www.safetyontheweb.com Placarding The regulations require specific placards for each of the nine hazard classes, as well as specific placards for those hazard classes that are further separated into divisions.

42 www.safetyontheweb.com Placarding Most bulk transport containers require four placards, one on each side and each end.

43 www.safetyontheweb.com Placarding As a general rule of thumb, placards must be visible on all four sides of a bulk packaging and at least three inches away from any other markings.

44 www.safetyontheweb.com Placarding If a portable container holds more than 119 gallons, but less than 1,000 gallons, the tank may be placarded on two opposite ends.

45 www.safetyontheweb.com Placarding Sometimes a material will have a primary and a secondary, or subsidiary, hazard. In these cases, placards showing both hazards must be displayed, but the secondary hazard class placard must have the hazard class number removed or obliterated.

46 www.safetyontheweb.com Summary Loading and unloading hazardous materials is a serious responsibility. Be familiar with and respect the hazards associated with the material you load or unload.

47 www.safetyontheweb.com Summary Follow all procedures and safe work practices, including proper selection of tools and Personal Protective Equipment.

48 www.safetyontheweb.com Summary Make sure you double check that all valves, fittings, caps, seals, and closures are properly secured, whether you used them or not.

49 www.safetyontheweb.com Summary Check the placards before releasing the bulk container.

50 www.safetyontheweb.com Summary Knowing and following the proper procedures can ensure safe transportation of bulk shipments.
