Adjuncts means devices used to assist swimming such as fins, mask, floatation aids.
Approved Filler means a person who meet local regulatory requirements to recharge a compressed gas cylinder (e.g. SWBA).
Approved Instructor means a person who meets the requirements laid out in this guideline as a SWBA Instructor.
Competent person is a person who meets local regulator requirements to perform visual and hydrostatic testing of gas cylinders.
Cylinder means an aluminum or composite wrapped gas cylinder not exceeding 450 ml (water volume) used as part of a type approved SWBA.
Breathing System means a SWBA product as specified in Annex A.
Guideline refers to this guideline (PSI Global Good Practice Guide – Swiftwater Breathing Apparatus).
Operator a person who is certified to use SWBA under this guideline or someone training to gain such certification under the direct supervision of an Approved Instructor.
Service Technician means a person who is authorised by the manufacturer to carry out maintenance on the respective SWBA.
Swiftwater Breathing Apparatus (SWBA) means the use of an emergency breathing system during swiftwater and floodwater activities to provide respiratory protection from aspiration of water, whilst remaining buoyant at the surface, without the intention to dive below the surface.

2.1.1 Personnel who undertake or support SWBA activities should be given an orientation to this guideline.
2.1.2 Operators should not be referred to as divers unless they are intending to dive and operate outside this guideline.
2.2.1 Operators should have the strength, physical fitness and mental health to undertake SWBA activities safely.
2.2.2 As a minimum they should be able to comfortably:
2.2.3 Operators should also have and maintain a medical clearance to a recreational dive medical or higher standard (CMAS, DAN, RSTC, UHMS).
2.2.4 Operators and Approved Instructor carrying out SWBA activities must not be impaired by fatigue, drugs or alcohol.
2.3.1 Operators must hold and maintain a recognised dive certification that meets ISO 24801-1 (supervised diver) or higher (such as a military or commercial diver certification).
2.3.2 Operators must hold and maintain a recognised swiftwater rescue technician certification (e.g. , IPSQA, PSI Global, Rescue 3, DEFRA, PUASAR002, NFPA etc.)
2.3.3 Operators should complete a recreational dive medical questionnaire and supply this to an approved instructor prior to commencing practical training. Practical training should not be undertaken if the operator fails any initial screening question, unless medical clearance is provided by a physician or medical practitioner.
2.3.4 SWBA certification and recertification training must consist of:
2.3.5 Maintenance of SWBA certification (2.3.4) should be done using a real-time verifiable document (i.e. online QR code).
2.3.6 Operators are exempt from Clauses 2.3.1 to 2.3.5 where they hold and maintain micro-credential certification in accordance with IPSQA Standard 5002 (Swiftwater Breathing Apparatus Operator) as this certification exceeds such requirements.
2.3.7 Operators should undertake an annual skills check to ensure proficiency in between recertification.
2.3.8 Approved Instructors must hold and maintain the following:
184.108.40.206 SWBA equipment should be cleaned and sanitized after use and between users to avoid infection. Solutions may include:
220.127.116.11 SWBA equipment used in natural waterways should be inspected and cleaned in accordance with local regulatory requirements (if any) to avoid spread of biosecurity risks (e.g. didymo)
18.104.22.168 SWBA equipment should be stored in protective cases in a secure, clean, dry and cool environment.
22.214.171.124 Storage of SWBA equipment in hot environments and in direct sunlight should be avoided as it may cause air expansion leading to burst disc rupture.
126.96.36.199 SWBA cylinders must be visually inspected by a competent person, no less than every two years.
188.8.131.52 SWBA cylinders should undergo a hydrostatic test by a competent person, no less than every five years.
184.108.40.206 SWBA cylinders should have their visual inspection and hydrostatic test certificate dates marked on their exterior.
220.127.116.11 SWBA fittings (regulators, hose, gauge) should be serviced annually or as per the manufacturers instructions by a service technician.
18.104.22.168 Recharging of SWBA cylinders must be done by an approved filler using breathable (non-enriched) air that meets air quality for diving.
22.214.171.124.1 Air quality should be periodically tested to ensure it is not contaminated.
126.96.36.199.2 SWBA cylinders should be fully charged (100%) before being stowed ready for use.
188.8.131.52 Where SWBA cylinders are to be stored not fully charged, they should be stored with nominal pressure (approximately 30 bar) to avoid moisture and other contaminants entering.
184.108.40.206 In the event of a burst disc, it should be replaced and the SWBA should be checked by a service technician.
