Tree care and arborist operations

An uncertified crew doesn't start a removal near a live line.

Taking down a tree beside a power line or on a protected lot is qualified work, and the certification that says a crew can do it safely expires on a date nobody watches. CrewOS checks the arborist's ISA certification is current before they can clock into a job that requires it, so a lapse keeps the saw in the truck instead of surfacing in an incident report.

The expensive failure

An unqualified crew is sent to drop a tree beside a live power line.

The ISA certification lapsed last season, or the climber was never qualified for line-clearance work, and no one caught it. The crew shows up, sets the rigging, and starts the removal a few feet from an energized conductor. Nothing looks wrong on the work order. The danger was there the moment the saw started, not the day someone finally opens the file.

What it costs

The tree job that goes wrong fails on the ground, not in an audit.

Contact with a power line is the leading way this work kills someone, and a mis-rigged limb drops through a roof or onto a car in seconds. A protected or heritage tree taken down without a qualified arborist is a bylaw violation with fines and a replanting order on top. The insurer, the utility, and the municipality all land on the same job, and none of them care that the crew meant well.

Operator control

The clock-in gate is yours to set, certification by certification.

You decide what gets checked, on which jobs, and how hard the system holds the line.

You decide which certifications gate a job and how hard the line holds. Nothing is enforced that you did not choose to enforce.The switch is yours. On the ISA Certified Arborist document type you turn on "required for clock-in" and choose whether a lapsed certification warns or hard-blocks. Set it once, and the gate is live on every job that carries it.

What the system will not let happen

The certification is tied to the tree job, and checked before the clock-in.

1In the compliance catalogue, the ISA Certified Arborist qualification is flagged as required for clock-in, so every removal or line-clearance job that needs a qualified climber carries the requirement automatically.
2CrewOS reads each arborist's certification expiry and counts it down on the compliance board, so a certification about to lapse shows up while you can still reassign the climb, not after the crew has rigged in.
3If an arborist whose certification has lapsed or is missing tries to start a job that requires it, the clock-in is stopped before the first cut. The gate does not depend on a foreman remembering to check the paperwork.

The direct answer

Can CrewOS stop an uncertified arborist from clocking into a tree removal?

Yes, where the ISA Certified Arborist qualification is set as required for clock-in. CrewOS checks the arborist's certification is current before they can start a job that requires it. A lapsed or missing certification is not current, so the clock-in is blocked until it is renewed.

The requirement is set once per document type in the compliance catalogue, and it reads from the certification's own expiry date. A certification that lapses between jobs blocks the next clock-in without anyone re-checking.

The outcome

No removal runs on a certification that has lapsed.

The check runs on every job that requires it, not only when a foreman thinks to look. Your crews stay qualified, your dangerous work stays in qualified hands, and the incident that would have happened at the base of the tree never starts.

Questions

What operators ask before they switch.

Does every certification block clock-in, or only the ones I choose?

Only the ones you set. Each certification in the compliance catalogue has its own clock-in rule, so you choose which are hard requirements for a job and which you simply keep on file.

How does CrewOS know a certification expired?

Every certification you track carries an expiry date. CrewOS watches it, warns you as it nears, and once it has passed the certification no longer counts as current for any gate that requires it.

We run certified arborists and ground crew. Can the gate tell them apart?

Yes. The gate reads each crew member's own certification record, so an arborist who holds a current certification clocks in normally and one whose certification has lapsed is stopped. A ground worker without the certification simply cannot satisfy a job that requires it.

Does the check only happen at clock-in?

No. CrewOS also surfaces who is eligible when you build the schedule, so an unqualified assignment is easier to avoid before the crew is ever dispatched. The clock-in gate is the backstop at the property.
