ADAS standards Q's Flashcards
- Which standards are relevant to occupational diving operations in Australia
AS2299.1 to 4 diving standards; AS2815.1 to 6 diver training standards; AS3848 gas filling and decanting standards; AS4332 gas handling standard; AS4360 risk management standard
- What is the minimum no. of divers required for a dive team using SCUBA to a depth of 7m
1 diver
- List the items of SCUBA equipment required by AS2299.2 standard for a SCUBA dive team
Breathing apparatus comprising a breathing gas supply with a first and second stage regulator,
a contents gauge (or gas supply safety warning system),
emergency gas supplies,
a mechanism for measuring the depth of the diver,
and a timing device. An appropriate diving suit.
- How often is an occupational diver required to have a medical examination
ANNUALLY
- Apart from the above, what other equipment is required by the standard to be on site
Weights, diver’s knife, surface signalling device, adequate O2 supplies and a suitable O2 delivery mechanism, communications equipment (e.g. VHF radio/phone)
- What are the responsibilities of the diver under the Occupational Health and Safety Act
To maintain their own safety and that of other employees;
To follow all organisational procedures; and
To follow all reasonable instructions given by their employer
- Describe the procedure for the following ascent/descent rate variations
(a) Ascent rate slower than 15m / min.
Add the extra ascent time to the diver’s bottom time when calculating decompression requirements
Describe the procedure for the following ascent/descent rate variations
Ascent rate faster than normal
Monitor diver’s condition for DCI symptoms. If symptomatic, treat for DCI. If not double stop time.
- List the pre-dive responsibilities of a UTAS Dive Coordinator
- Ensuring that the diving operation, Risk Assessment, and all dive sites have been registered with and approved by the UDO on TUFSS prior to departure for the trip.
- Ensuring all divers on the dive team are listed as current on the University Diver Register
- Communicating all identified issues from the Risk Assessment to all other divers on the dive team;
- Notifying a Nominated Contact of all required details of the diving operation, and ensuring the Nominated Contact is aware of their responsibilities in the event that personnel from the trip do not report by the designated time;
- Conducting a pre trip briefing with the Master of any mother ship being used for a UTAS diving operation, before the ship leaves port, detailing the diving activities to be undertaken;
- Ensuring that all required diving and safety equipment is in good working order, has been packed (including adequate oxygen supplies), and is transported to the dive site;
- Determining whether or not travel after the dive will exceed an altitude threshold, and ensuring that the correct delay before travelling after diving is observed - taking into account the type of diving done, and any risk factors that may require an extension to the delay period;
- Restricting or suspending any operation considered unsafe, whilst in the field, with particular attention to weather forecasts and prevailing conditions;
- Ensuring there are adequate means of communication at every dive site in case of emergency;
- Conducting a pre-dive briefing in the presence of the entire Dive Team (including Dive Attendants, Boat Handlers and Divers) and discussing all necessary risk control measures with the Dive Team, in particular where any dive operation contains one or more of the high risk factors listed in various sections and appendices of this Manual;
- Ensuring every diver is fully aware of their particular tasks for the dive, including knowing which other divers that they are to act as a buddy for;
- Assessing the fitness of all team divers on site immediately before the dive, and vetoing any dive as required where there is some uncertainty that a diver can safely complete it;
- Nominating a Dive Leader to control the underwater part of the diving operation for each dive team, where there are multiple teams or when the Dive Coordinator is staying at the surface during the dive;
- Delegating full responsibility for monitoring the diving operation, including diver recall and diver safety, to the Dive Attendant in the event that the Dive Coordinator intends to dive;
- Ensuring all divers conduct a pre-dive equipment check of their own and other diver’s equipment, including performance of a ‘bailout’ contents check (to be recorded by surface attendant) & a bailout activation drill by any diver wearing ‘bailout’ equipment;
- Ensuring all divers are using the dive computer issued to them;
- Ensuring all required Dive Record Form pre-dive information is accurately recorded on the form.
- Ensuring all divers are aware of their current nitrogen loading status before entering the water, as well as of the permitted maximum bottom time for the intended maximum dive depth and the next deepest depth group on the decompression tables.
