Meet Andy Knebel, Owner and Head Instructor of Safety Helpers L.L.C.
Andy Knebel is an authorized instructor of OSHA’s 10- and 30-Hour General Industry Training courses. After finishing his studies at Southern Illinois University as a Math major under a teacher’s scholarship, he began working at an oil additive plant in 1973.
In 1977, while on strike, he answered a newspaper ad about a similar job at a plant that made bulk pharmaceutical medicines in Boulder, CO. The company needed a safety program, and Andy took on the job when he was given the opportunity to develop it as he believed it needed to be.

Andy’s exposure in the safety industry happened years before the OSHA, DOT, and EPA developed training requirements for professionals who address hazardous material spills. Only in 1986 was the HAZWOPER (Hazardous Waste Operations and Emergency Response) finalized, after the Bhopal disaster happened.
When Andy saw that the training he had been conducting for years meets the very specific HAZWOPER training requirements, he continued working in the environmental, health, and safety field, until he left the company in 1997. Following this, he started a business renting out camper vans and motor homes.
His business shuts down every winter, so he continued to be involved in the safety industry as a consultant. He would occasionally be hired to do worksite audits focused on National Fire Protection Association (NFPA)’s Life Safety Codes and conduct OSHA-required training for insurance companies and manufacturing plants.
In 2010, Andy helped establish Safety Helpers, L.L.C, where he is currently Head Safety Instructor. He presently conducts the HAZWOPER and DOT HAZMAT Training and helps thousands of students across the country.
