Who This Is For
Plant turnarounds, tank and vessel cleaning, sewer and drain work — any job that needs people to enter a confined space and come back out safely.
Tank & Vessel Cleaning
Storage tanks, silos, digesters and process vessels that require internal access for sludge removal, inspection or repair. Atmospheric testing and continuous standby are non-negotiable.
Sewer & Drain Work
Manhole entry, pipe relining, pump-station maintenance and culvert inspections. Toxic gases, low oxygen and flooding risks make standby persons essential.
Emergency or Unplanned Entry
Blockages, leaks or equipment failures that force an immediate confined-space entry. We confirm AGTES availability as quickly as possible for urgent call-outs.
What Naja Arranges

Frequently Asked Questions
What does an Authorised Gas Tester and Entry Supervisor (AGTES) do?
The AGTES is a competent person appointed to conduct atmospheric gas testing and supervise the entry process into a confined space. Under the Industry Code of Practice for Safe Working in a Confined Space 2010, the AGTES tests oxygen levels, flammable gases and toxic substances before anyone enters, and remains on site to supervise the entry until the work is complete or the permit is cancelled.
How is a standby person different from an AGTES?
The standby person remains outside the confined space for the duration of entry operations. They maintain an accurate count of entrants, monitor conditions, communicate with the team inside, and summon rescue services if needed. The AGTES handles atmospheric testing and entry supervision; the standby person handles continuous monitoring and emergency response from outside.
Does Naja Safety train or certify AGTES personnel?
No. Naja Safety does not train or certify AGTES personnel. We arrange AGTES and standby persons who have already completed training at DOSH-registered training providers and hold current registration. AGTES training must be done at a training provider registered with the Director General, and DOSH issues the registration certificate.
How much notice do you need to arrange confined-space personnel?
For planned shutdowns and tank cleanings, two to four weeks is ideal. For urgent or emergency work, contact us immediately and we will confirm availability as quickly as possible. The more notice you give, the better we can match your site with personnel who have the right experience for your specific confined-space hazards.
What information do you need from us to arrange the personnel?
We need the site location, the dates and shift times, the number of confined-space entries planned, a brief description of the work (tank cleaning, pipeline repair, sewer inspection, etc.), and any known atmospheric hazards. We also ask about your existing rescue arrangements so we can confirm the standby person's duties are aligned with your emergency plan.
