We have been running this machine for years. Do we still need a review?
Possibly. The obligation attaches when equipment is newly installed, relocated, or modified in a way that affects a listed circumstance, including guarding that was removed and never reinstated, or a control system that was rebuilt. Legacy equipment that has quietly been modified is the most common finding we make on a first visit.
Our DHA was done under NFPA 652. Is it still valid?
NFPA 660 took effect in December 2024 and consolidated NFPA 652 along with the five commodity specific dust standards. The fundamentals carried across largely intact, so a well built DHA under 652 is not worthless. But the five year revalidation cycle still applies, and any jurisdiction or insurer that updates its adopted edition will expect the current reference. If your DHA is approaching five years old, or if the process has changed since it was written, it needs revisiting.
How long does a review take?
A single apparatus is typically a half day on site with a sealed report inside five to seven business days. A full production line or a multi collector dust system runs longer. Rush turnarounds are available when a start up date is at risk. Tell us the date on the scope call and we will tell you honestly whether we can hold it.
What happens if the review finds deficiencies?
That is the normal outcome and it is not a failure. The report ranks each deficiency by risk with a specific corrective measure. You complete the corrections, we re-verify, and the compliance confirmation is issued. The equipment cannot be operated with workers exposed to the unmitigated hazard until that is resolved.
Do you handle the corrections as well as the review?
We specify them, and we can produce the guard, interlock and control panel designs. We deliberately do not sell you the hardware or install it on the same project we reviewed. An independent review loses its value the moment the reviewer has a stake in what gets bought.
Do you travel outside the Ottawa area?
Yes. We serve all of Ontario, from Windsor and London through the Golden Horseshoe to Ottawa, Kingston and northern operations. Travel is quoted transparently in the fixed fee rather than added afterwards.
What does a review cost?
It depends on the number of apparatus, the hazard type and travel. We quote a fixed fee before mobilising, on one of three bases: per apparatus, per line or cell, or a program retainer for multi site manufacturers. The trigger determination itself, working out whether you need a review at all, is free.
