Process Safety, Nuclear Plant and Facility Safety Fun

Posted by The Fauske Team on 12.18.14

We spend a lot of time discussing serious issues here - related to the responsibility for element of surprise 272preventing reactive chemical hazards, combustible dust, gas and vapor flammability, nuclear plant safety testing, analysis and obsolescence, industrial plant safety, etc. Because we are an engineering and testing lab with 35 years of experience, we have seen many a scenario requiring testing for compliance as well as for safety needs beyond any ordinance or regulation. 

We provide plant operability testing and code analysis for severe accident phenomena to support both nuclear and environmental safety, as well as state-of-the-art methodology and laboratory tools for characterizing chemical systems.  

We provide more than 25 nuclear safety services including Acoustic Analysis, Debris Intrusion, Cable Health Aging Management Program (CHAMP™), Chemical and Radioactive Waste Safety,  Circuit Analysis, Commercial Grade Dedication/Reverse Engineering and Obsolesence Replacement,  Custom Engineering, Decontamination & Decommissioning (D&D) Process Engineering, Equipment Qualification (EQ), EMC, Fire Modeling, Loss of Coolant Accident (LOCA) Test Chamber, Severe Accident Mitigation/ Prevention/ AnalysisWaterhammer, Facility Flow, Aerosol, Thermal and Explosion Model (FATE™) 2.0, Post-Fukushima Engineering and so much more. Reverse engineering is one of our most innovative and fun areas.  We are a problem solving bunch, for sure.  

Our non-nuclear side provides state-of-the-art laboratory testing services to cater to OSHA, NEP, NFPA, ASTM, PSM, PHA, HAZOP/LOPA needs. Testing for Combustible Dust, Flammable Gas and Vapor, Adiabatic Calorimetry & Instrumentation, Reaction Calorimetry & Instrumentation, UN-DOT  and Thermal Stability are among our many offerings. FAI is ISO-17025/IEC, ISO-9001 Accredited and TickIT Certified. On-site assessments, Risk Management Services, Calculations, DIERS Methodology, Relief System Design, and Safety Program Reviews are just some of the safety related services offered by FAI.  We also produce an extensive parts & equipment catalog shown here in our website store.  FAI also customizes parts as requested. 

While we specialize in safe scale up of chemical reactions and severe accident prevention - I believe one of our strong suits is customized testing and engineering. Beyond regulatory compliance, which has ever changing rules, we help customers stop the finger pointing where gaps are concerned.  It is very satisfying to help customers look at the big picture, to understand that their facility is not significantly different from most others and that the focus should be on closing any safety gaps on a priority basis to create a safer and more compliant working environment.  

As we reflect at year's end and marvel at our own talented and creative staff of nuclear, chemical and mechanical engineers and other professionals, we thought it would be fun to share some of our warped sense of humor with you other amazing chemical, plant, nuclear and facility manager types, too.

Hope you enjoy a chuckle and many blessings for wonderful holidays and a happy, healthy year ahead! 

Chemistry Lab Safety

What is the most important chemistry rule ? Never lick the spoon!

Superhero Chemistry Pun

If Iron Man and Silver Surfer teamed up, they'd be alloys.

The Half Empty Glass

The optimist sees the glass as half full. The pessimist sees the glass as half empty. The chemist sees the glass as completely full, half in the liquid state and half in the gaseous state.

Cash Chemistry

It has been discovered that money consists of a yet-to-be-indentified superheavy element. The proposed element names is Un-obtainium.

Chemistry Joke Pun

I wish to apologize for not having more chemistry jokes, but I only add them periodically.

Facility Safety Signs... Some, We've Actually Seen 

  • We upped our safety – up yours!
  • Follow the safety rules or you will be fired before you hit the ground
  • “In case of fire, exit building before tweeting about it.”
  • You can't pick up your pay with no fingers
  • You’ll look pretty stupid trying to eat corn on the cob with no teeth
  • Please work safely today – we are getting a visit from Head Office
  • Dont slip when carrying your breakfast – you’ll end up with egg on your face
  • While on a ladder, never step back to admire your work
  • Ladder safety has it’s ups and downs. (also works with elevator and escalator safety)
  • Safety is great unless you’re late
  • Safety – been there, done that
  • Hold my beer and watch this
  • Dont get hurt or you’ll get fired
  • Safety’s fine if you got the time
