Are you identifying human factors in HAZOP studies?

On 6.9.19, at Amsterdam airport, a Boeing 737, aircraft was taxiing in a northerly direction on taxiway Charlie to runway 18C when it received take-off clearance for that runway. The flight crew then drove on taxiway Delta in a southerly direction and commenced the take-off. Air traffic control noticed this and instructed the crew to stop immediately. The crew aborted the take-off run and taxied back to the start of runway 18C, after which the aircraft took off uneventfully.

My article on Flare Systems published in Chemical Engineering progress of AIChE

When I started my career 40 years ago, I used to be an avid reader (and still continue to be) of Chemical Engineering Progress of the AIChE. The articles helped me throughout my career. I am happy to say that my third article
"Manage Change to Flare Systems" has been published in the January 2020 issue of CEP. Please see it in this link

Glycols can burn

Incident #1
An atmospheric tank overfilled with glycol. The glycol came in contact with a nearby burner, igniting and causing a fire.
Incdient #2
Employees #1 and #2 were installing a platform on top of a storage tank containing ethylene glycol. While the tank was receiving an ethylene glycol mixture from the process line, Employee #1 began to weld a clip on the tank. Shortly after striking the arc, the top of the tank blew open and the contents ignited. Employee #1 received burns, lacerations, and fractures which later resulted in his death and Employee #2 received minor cuts and bruises.  Source: osha.gov

Have you checked the MSDS of the glycols you are using? Often operators think that glycol is not flammable.
