How Does Process Mercury Affect Safety?

Mercury and its compounds are simultaneously toxic, persistent, and accumulative in the environment. And in hydrocarbon processing mercury presents risks to workers, process and the environment which requires an understanding of mercury speciation and distribution in process to develop appropriate plans and procedures.  Exposure risks may sometimes be underestimated due to the physiochemical properties of mercury and limitations of certain instruments used for occupational exposure monitoring.

ISCT understands these limitations and provides process mercury safety and environmental solutions to the oil and gas industry and integrate process mercury concentration data into comprehensive safety and management plans that increase safety performance and operational efficiency of assets. By understanding the toxicological and physiochemical properties of mercury and forecasting possible exposure pathways we help our clients better protect their personnel and the environment.

Risk Management

Institutionalize the risk management through policy, training, enforcement, assignment of responsibilities.
This is the right way to manage risks.  However in many cases, such as with mercury, the path is not direct.


Risk Awareness

We realize we have a problem.


Risk Assesment

We assess how bad the problem is (sum of possible consequences and chance of each happening)

Risk Mitigation

We take appropriate cost-effective steps to manage the risk.  Cost of mitigation compared to reduction in assessed risk.

How Can We Help?

For new assets with mercury in inlet streams and those that routinely manage mercury during maintenance and Turnarounds with administrative and engineering controls, ISCT provides environmentally safe chemicals (ISCT 400-91C™) for decontamination of personnel and equipment leaving confined contaminated zones in plant areas (process equipment, towers and product tanks).


Training and education of workers and project teams


Occupational exposure studies and area/event monitoring (portable XRF, MVA, active and passive sampling)


Active and annual mercury surfaces screening (XRF flange plate monitoring)


Exposure monitoring, data assimilation, reporting and interpretation


Develop and implement process stream monitoring plans for environmental emissions compliance

We provide our customers with accurate, reliable and defensible data; maximizing and protecting the integrity of your assets throughout their lifecycle.
