A fabrication shop in Foothills Industrial stops its line at 6 p.m. on a Friday. Maintenance has 72 hours to replace a conveyor drive and the electricians have a panel upgrade booked, but nobody has decided who cleans the overhead steel, or when. By Sunday night the cleaning crew is working underneath the millwrights and Monday’s restart slips.
When a shutdown clean goes wrong in a Calgary plant, the cause is usually in the planning, weeks before the line stops.
What is shutdown cleaning in a manufacturing plant?
Shutdown cleaning, also called turnaround cleaning, is a planned deep clean carried out while production is stopped for maintenance. It covers the areas crews cannot reach safely while equipment runs: overhead structure, machine bases, pits, trenches, and floors under fixed equipment.
A shutdown is usually a short stop of a few days. A turnaround is a longer outage with several trades on site, often scheduled once a year.
Shutdown cleaning timeline: six weeks out to restart
- Six weeks out, walk the plant with your cleaning contractor and maintenance lead. List every area by what it needs for access: lifts, lockout, or entry permits.
- Four weeks out, fix the written scope: areas, methods, crew size, and shift lengths. Send your contractor safety requirements now so the paperwork comes back before the outage.
- Two weeks out, sequence the trades. Cleaning runs from the top down, so high dusting goes first, before maintenance opens equipment. Floor degreasing and scrubbing go last, after the other trades have left.
- One week out, confirm the logistics: lift rentals, water and power access, site orientation times, and where sludge, oily water, and used absorbents will go.
- During the shutdown, have the cleaning supervisor and your shutdown coordinator meet for ten minutes every shift. That catches scope changes early.
- At the end, walk the plant together and sign off area by area, with photos, before equipment is re-energized.
What belongs in a shutdown cleaning scope
| Plant area | Cleaning task | Why it waits for the shutdown |
|---|---|---|
| Overhead beams, piping, and light fixtures | High-level dust removal from lifts | Lifts cannot work above a running line |
| Machine bases and under fixed equipment | Degreasing and removal of built-up oil and debris | Guarding and moving parts block access during production |
| Pits, trenches, and sumps | Sludge removal and washdown | May be restricted or confined spaces that need permits |
| Production floors | Degreasing and auto-scrubbing | The floor is clear of pallets and forklift traffic |
| Lunchrooms, washrooms, and locker rooms | Deep cleaning and floor care | Staff are off-site |
Cleaning companies ( like MCA Group ) work around, under, and on the exterior of equipment. Servicing the inside of machinery stays with your maintenance team.
Alberta safety rules that shape the schedule
Cleaners on a shutdown work under the same Alberta Occupational Health and Safety Code as every other trade on site. Four parts affect the plan most:
- Part 2 covers hazard assessment. Ask for a written one that covers the cleaning scope.
- Part 15 covers the control of hazardous energy. Where cleaning puts workers in contact with machinery, its energy sources have to be isolated and secured first, so build that time into the schedule.
- Part 5 covers confined spaces. Pits, tanks, and some trenches can count as confined or restricted spaces, which brings a code of practice, entry permits, and atmospheric testing.
- Part 29 covers WHMIS. Hazardous products such as degreasers and solvents need safety data sheets on site and trained users.
Calgary’s climate matters too. The dry air keeps fine dust loose, so overhead surfaces load up between outages, and if your process produces combustible dust that buildup is a fire hazard. In a winter shutdown, washdown water near dock doors can freeze, and grit tracked in from the yard should come off the floor before scrubbing starts.
Four planning mistakes that delay restart
- Booking cleaning after the maintenance schedule is frozen.
- Scrubbing floors before the trades finish, then paying to do it twice.
- Leaving waste disposal undecided until the sludge is already in drums.
- Skipping the area-by-area sign-off, so missed items surface after startup.
Shutdown cleaning questions from Calgary plant managers
How far ahead should we book shutdown cleaning in Calgary? Book four to six weeks ahead for a short shutdown. Allow longer for a multi-week turnaround, or for common shutdown periods such as summer and late December.
Can cleaning and maintenance run at the same time? Yes, in separate zones. Sequence the work by area so cleaners are never beneath or beside open equipment.
Plan your shutdown clean with MCA Group in Calgary
MCA Group provides shutdown and turnaround cleaning for manufacturing plants across Calgary’s SE industrial quadrant, including Foothills, Shepard, Manchester, Highfield, and Ogden. Crews carry WCB Alberta coverage and WHMIS training, and can work within COR and SECOR contractor requirements.
MCA Group has handled phased work at height on a large site before. For developer TSL, the team handled the post-construction clean of a 500,000+ sq. ft. industrial facility over about six months, with more than 20 people on site daily during a 60-day intensive phase. The work included high dusting and specialty ceiling cleaning from scissor and boom lifts by certified operators, plus machine floor scrubbing. ( Read Case Study )
