WHAT WE DO

Eight practice areas, one engineering file.

If a piece of equipment needs a seal before it runs, it falls somewhere on this list. Every service below is delivered anywhere in Ontario, from Windsor through the Golden Horseshoe to Ottawa and the north.

Pre-Start Health & Safety Reviews

O. REG. 851, S. 7

Trigger determination, site inspection, standards gap analysis and a sealed report with a deficiency list your team can close out.

  • New installs, relocations and modifications
  • Retroactive reviews on legacy equipment
  • Re-inspection and compliance confirmation after corrections
  • Design stage advisory so problems are caught on paper

  • Task based hazard identification and risk scoring
  • Required Performance Level, category and diagnostic coverage
  • Minimum safety distance calculations to ISO 13855
  • Fixed guard, interlock and control system specification
  • Hazardous energy control and lockout review to CSA Z460

Dust hazard analysis

NFPA 660 (2025) · NFPA 68 · NFPA 69

Full DHA under the consolidated combustible dust standard. Material characterisation, compartment by compartment hazard identification, and a ranked mitigation plan you can budget against.

  • Sampling and lab coordination for Kst, Pmax, MEC, MIE and LOC
  • St class determination and deflagration index review
  • Accumulation thresholds, housekeeping and ignition source control
  • Five year revalidation and management of change

Explosion protection & dust collectors

NFPA 68 · NFPA 69 · NFPA 91

Collector siting, deflagration venting, isolation and suppression reviewed against the standard, with the calculation package your insurer and AHJ keep asking for.

  • Vent area sizing and vent path calculations to NFPA 68
  • Chemical, mechanical and passive isolation to NFPA 69
  • Ducting, return air and hazardous location review
  • Compliance upgrade paths for existing collectors

Anchor load testing & structural verification

S1001 · ASTM E488 · ASTM E3121 · CSA A23.3 ANNEX D

Field proof load testing on the anchorage that holds your racking, guarding, mezzanines and equipment down, with a sealed report of measured loads and displacements.

  • Confined and unconfined tension proof load testing
  • Torque verification and installation inspection
  • Concrete breakout, pullout and bond failure assessment
  • Racking anchorage review to CSA A344

Control panels & safety circuits

CSA C22.1 · CSA C22.2 No. 14 · ISO 13849-1

Panel design and build, safety relay and safety PLC architecture, and verification that the installed circuit does what the drawing says it does.

  • Control panel design, fabrication and labelling
  • Safety relay, dual channel and forced guided contact wiring
  • Safety PLC logic review and functional verification
  • Short circuit current rating and protective device coordination

Commissioning witnessing & TAB

INDEPENDENT THIRD PARTY · ASHRAE 111

Independent commissioning attendance and functional testing, plus balancing verification on ventilation and dust extraction systems.

  • Functional and integrated systems testing
  • Witnessed start up and performance verification
  • Airflow, capture velocity and duct balancing verification
  • Issues logs, hold points and closeout reporting

Fire & life safety code review

NFPA 30 · NFPA 33 · NFPA 86 · NFPA 51B · OBC

Code review where a process touches fire and life safety: flammable liquid storage, spray application, industrial ovens and hot work.

  • Flammable and combustible liquid storage to NFPA 30
  • Spray application operations to NFPA 33
  • Ovens and furnaces to NFPA 86
  • Hot work programs to NFPA 51B

Let's find out what needs a review.

Send drawings or photographs and we will tell you plainly whether a review is required, before any fee is discussed. We work across all of Ontario.
