Hazmat placarding

Hello everyone!!! This is my first post here and want to know at what point do you placard for a flamable class 3. I drive for a company in the marine industry. All we do is service ships. Wether its offloading bilge water(slops) or bunker oil. Its mostly water. But at times we will pump off diesel fuel mixed with water.

What I want to know is what's the flash point that makes a load a hazardous one requiring placarding? I pull a sample and test for water content so I know what manifest to put it on(haz or non-haz) but I have no way to test for flamability.
I don't know its hazardous till I get to the offloading facility and load gets rejected for low flash. Anyone experienced with this?

 

Make that a haz waste and non haz waste

 

I got the UN# but at what flash point makes it a hazardous load requiring placards? Is it 100 degrees? Or what?

 

Thanks for that! Did not know bot that site. Answers my question to the fullest. Now I have to figue out how to test for flamability prior to transporting lol.

 

Yeah, I got you. The thing is we do most offloading dockside over the water and coast guard requirements are strict and to them what we do out on the road has nothing to do with them. I know the generator should be the one to test for hazardous but they don't or they have no way I guess

 

I understand about the haz mat requirements. I've been dragging tanker for a long time. We don't pick up from shippers. We pick up from the generator of the waste which is the ship. On haz waste manifest your using non- rcra as the description.
Again, I have no way to determine whether the load is flamable or not till I get to the offload facility. Coast guard regs prohibit open flame therefore I can't test.
