Safety checklist — Heavy equipment mechanic
Maintenance and repair of construction equipment. Based on Québec's Construction Safety Code (CSTC) and CNESST standards.
Before work
11 items- ✓
PPE worn: hard hat, safety glasses, gloves, steel-toed boots, hearing protection
- ✓
Machine immobilized on stable, level surface
- ✓
Engine off, key removed, parking brake — then 2.20 lockout if in the danger zoneCritical
ℹ️ CSTC 2.20 for work in the danger zone. Killing the engine is not by itself 2.20. Not a “zero tolerance” rule.
- ✓
Hydraulic attachments lowered to ground or mechanically blocked
- ✓
Hydraulic fluids and fuel — WHMIS sheets available
- ✓
Fire extinguisher accessible if hot work
- ✓
Do not work under equipment supported only by hydraulics (CSTC 2.20 / 3.10.4)Critical
ℹ️ 2.20: control energies. 3.10.4 (4) if lifting apparatus. “Mechanical blocking mandatory” is not a named pair.
- ✓
Hydraulic circuits depressurized before opening fittings
- ✓
Hot parts (turbo, manifold) cooled before handling
- ✓
Used oils and fluids collected in proper containers
- ✓
Hydraulic hoses inspected — replace if swollen, cracked or damaged
After work
4 items- ✓
Functional test performed — check for leaks and proper operation
- ✓
Guards and access panels reinstalled
- ✓
Used fluids disposed per environmental regulations
- ✓
Maintenance report completed in machine logbook

Risks and prevention — Heavy equipment mechanic
Maintaining construction machinery (excavators, loaders, cranes) involves burn risks (hot hydraulic oil, turbo), crushing under components, and high-pressure hydraulic injection. On a construction site, CSTC 2.20 governs lockout. Mechanically blocking before working under a load is safety practice — not a named CSTC+RSST pair.
Pressurized hydraulic fluid can penetrate skin and cause severe internal injuries. Fittings must be depressurized and systems mechanically blocked before disassembly. Mechanics must inspect hoses for wear, abrasion, and leaks before returning equipment to service.
