Hazmat Classification: Marine Pollutants

The list of marine pollutants in the Hazardous Materials Regulations is a long one, and some marine pollutants are regulated more stringently as severe marine pollutants. A mixture could be a marine pollutant too, even if the concentration of a marine pollutant in the mixture is as little as 1%.

Identify and classify marine pollutants with confidence—download Lion's newest guide for hazmat shippers, Hazmat Classification: Marine Pollutants.

Cheat Sheets: RCRA and DOT Training

Use these two cheat sheets to brush up on some of the fundamentals of hazmat and RCRA compliance, such as what training is required, who needs to train, and when and how often they need training.

The instructor clearly enjoys his job and transmits that enthusiasm. He made a dry subject very interesting and fun.

Teresa Arellanes

EHS Manager

The workshop covered a lot of information without being too overwhelming. Lion is much better, more comprehensive than other training providers.

George Alva

Manufacturing Manager

Very well structured, comprehensive, and comparable to live training seminars I've participated in previously. I will recommend the online course to other colleagues with training requirement needs.

Neil Luciano

EHS Manager

Lion's course was superior to others I have taken in the past. Very clear in the presentation and the examples helped to explain the content presented.

George Bersik

Hazardous Waste Professional

Lion courses always set the bar for content, reference, and practical application. Membership and access to the experts is an added bonus.

John Brown, CSP

Director of Safety & Env Affairs

Excellent course. Very interactive. Explanations are great whether you get the questions wrong or right.

Gregory Thompson

Environmental, Health & Safety Regional Manager

The instructor took a rather drab set of topics and brought them to life with realistic real-life examples.

Tom Berndt

HSE Coordinator

The online course was well thought out and organized, with good interaction between the student and the course.

Larry Ybarra

Material Release Agent

My experience with Lion training, both online and in the classroom, is that they are far better organized and provide a better sequential explanation of the material.

Robert Roose

Manager, Dangerous Goods Transportation

Given the choice, I would do all coursework this way. In-person courses go very fast without the opportunity to pause or repeat anything.
