First 60 Minutes After a Major Breakdown
Generate a first-60-minutes action plan for responding to a major equipment breakdown.
Failure data
First 60 minutes action plan
- Make sure no one is in danger — keep a safe distance from the equipment
- If necessary, use the emergency stop. Before intervening in the equipment, isolate all hazardous energy sources in accordance with your company’s LOTO (lockout/tagout) procedure and verify that no energy remains
- Restrict access to the hazard area (tape, signs) if visible hazards exist (leak, heat, moving parts)
- Notify the shift supervisor or production manager of the failure
- Notify the maintenance team and, if needed, an automation technician/electrician
- If the failure affects deliveries or customers, notify sales/customer management early
- Gather initial symptoms: sounds, error messages, leaks, odors, vibration
- Check recent maintenance history and equipment logs (PLC/HMI error messages)
- Take photos/video of the problem — for evidence and for a later root cause analysis
- Decide whether the failure can be resolved by the on-site team or needs an outside specialist
- Check the availability of needed spare parts and backup equipment
- If the repair will take a long time, start up an alternative production capacity or workflow
- Define the next specific steps and who owns them
- Set an initial estimated timeline for recovery and inform management
- Document everything done so far — this is the basis for a later root cause analysis (5 Whys)

Request fast failure diagnosticsHow the calculation works
The guide gives a five-phase action plan for the first hour after a major failure: 0–5 min safety, 5–15 min notification, 15–30 min diagnosis, 30–45 min decision and 45–60 min action plan, each with three concrete steps. You enter the machine, date, the person who received the report and a short description of the failure, and get a printable sheet.
Example: enter “Line 2, press hydraulics failure” and you get a ready timeline you can print and keep at the machine.
Frequently asked questions
Why just the first hour?
The initial decisions determine how quickly and safely work is restored. A clear sequence reduces chaos.
Does the guide replace company procedures?
No, it is a general basis. Supplement it with your own safety and escalation rules.
What happens after the hour?
Do a root-cause analysis (5 Whys) and draw up corrective actions.

Methodology and limitations
Methodology based on standard industry calculations and Maintest’s practical industrial experience. This tool provides a planning estimate and does not replace project-specific engineering assessment. This tool is a screening and planning aid developed by Maintest. Results are indicative and depend entirely on the figures and answers you enter. They are not an engineering calculation, a safety assessment or a substitute for the manufacturer’s instructions, applicable standards or professional judgement. Weights, benchmarks and default values are Maintest planning assumptions and can be adjusted to your situation. Do not use this tool as the only basis for safety-critical decisions such as lifting, electrical work or lockout procedures.
