Thirty minutes after the torch goes off is the rule, and it is the easiest line on a paper permit to sign before it has actually run. This holds the permit open until the clock has genuinely finished and the watch keeper has confirmed the area is cold — on your phone, in the field, with no signal.
One-time purchase. No subscription. No account. Works offline.
Mark the work complete and a live countdown starts against the OSHA 1910.252(a) thirty-minute minimum. The permit will not move to Closed until that clock has fully elapsed, so an early sign-off is not something the form will quietly accept.
Type in LEL, oxygen, hydrogen sulphide and carbon monoxide and each is checked against your thresholds. A gas left blank is reported as not recorded rather than counted as a pass, and a failing reading blocks the permit from being issued at all.
Every test carries the detector serial and its last calibration date. Past thirty days and it is flagged on the permit and on the status screen — the exact cross-check a 2026 hot work audit runs against your gas-free certification.
Print any record as the full permit form — the work, the eight pre-work checks, every gas test, the fire watch times and both signature blocks — for the file, the client pack or the fire marshal. CSV export for the spreadsheet.
Welding, cutting, grinding, brazing or soldering, with the site, the exact location, the equipment and a description of the job.
Performing technician, contractor company, the authorising person who issued it, and the named fire watch.
Eight checks from 1910.252(a): the 35 ft clearance, shielding, openings covered, sprinklers in service, extinguishers staged, area swept, neighbours told, equipment purged.
Initial test and every retest, each with the four gases, the tester, the detector serial and its calibration date.
Valid-from and valid-to times, so a permit still open past its expiry is visible instead of buried.
When the work stopped, when the watch started and ended, who stood it, and their confirmation that nothing is smouldering.
Every pre-work check takes an explicit Yes, No or N/A. A blank is never read as a yes, an unanswered check blocks the permit from being issued, and answering No forces you to write down what is in place instead.
A permit sits in exactly one state, worked out from what you have recorded. Nothing advances on the strength of a blank field.
Oil Rigs Now has served oilfield professionals since 2011. This is a recordkeeping tool, not a permit authority — it does not measure any atmosphere, does not authorise hot work, and does not replace your employer’s hot work programme, the authorising person’s inspection of the area or a calibrated gas detector. It keeps the checks, the readings and the clock honest so the paperwork stops being the weak link.
Everything stays on your device. Nothing is uploaded, no account is created, and the app keeps working when the truck has no bars.
