Standby person (confined space)

A standby person sits outside a confined space for the full entry, holds continuous communication with entrants, and must never enter to attempt rescue.

Ask Chalkline about this →

A standby person is the competent worker stationed outside a confined space for the entire duration of an entry, holding continuous communication with the entrant(s) and summoning rescue if anything goes wrong. The role is mandatory under model WHS Regulation 76 for any confined space entry in residential and commercial construction.

What the standby person does

DutyWhy
Maintain continuous communication with entrants (voice, hand signals, radio)Detect distress immediately if voice contact stops
Monitor the entry permit, atmosphere readings, and timeConditions can change in seconds (oxygen drop, build-up of CO, slurry release)
Trigger emergency response (call 000, deploy rescue plan) if neededThe first 60 seconds determine survival in a low-oxygen environment
Account for every person entering and exiting (sign-on register)Confirms nobody is left inside
Refuse entry to anyone not on the permitStops curious workers from wandering in

The rule that gets workers killed: NEVER enter the space

The standby person must not enter the confined space to attempt rescue under any circumstances. Most Australian confined-space fatalities involve a would-be rescuer entering and being overcome by the same hazard that disabled the original entrant. The rescue is done by trained rescue personnel with self-contained breathing apparatus, retrieval harnesses, and confined-space tickets, summoned by the standby person calling 000 or activating the site rescue plan.

This is non-negotiable. SafeWork prosecutions have followed cases where the standby person broke this rule, even when their intent was clearly to save a mate.

Competency requirements

A standby person must be trained and competent in:

  • The hazards of the specific confined space.
  • The atmospheric testing equipment in use.
  • The site’s confined-space entry permit system.
  • The emergency response plan.
  • Communication methods (radio protocols, hand signals).

Many sites require a nationally-recognised confined space entry ticket (RIIWHS202E or equivalent) as the competency standard, with refresher training every 2 years.

When a standby person is required

For every confined-space entry classified as such under the WHS Regulation definition. Common construction triggers:

  • Underfloor work where the crawl space has restricted egress.
  • Pier holes deeper than 1.5 m.
  • Pump pits, septic tanks, or sewer connection work.
  • Stormwater pits and chambers.
  • Service tunnels and crawl ducts.

See confined spaces (WHS) for the full entry-permit procedure.

Also known as: confined-space standby, attendant, watcher.
