Industrial tank cleaning safety is not a generic hazard profile. This work stacks multiple high-consequence risks in one place: 

• confined space entry and restricted access 

• flammables and hydrocarbons 

• atmospheric hazards and gas monitoring 

• ignition control, grounding, and static risk 

• chemical exposure and protective suit selection 

• heat stress inside a steel tank, especially in summer 

• rescue complexity if something goes wrong 

Federal guidance on confined spaces in Canada outlines why these spaces are high-risk, enclosed, not designed for continuous occupancy, with restricted entry or configurations that complicate rescue. CCOHS also emphasizes that an entry permit is used to document hazard identification and risk assessment for each confined space entry.  

In Alberta, OHS Code Part 5 requires employers to maintain a confined space code of practice and outlines what must be in place before workers enter a confined space.  

That matters in industrial tank cleaning because much of the work takes place in confined spaces, with real safety obligations attached to every entry.
