SCOPE AND APPLICATION

The safety of all Surf Life Saving (SLS) members and the community who participate in SLS activities is paramount. Since we operate and participate in an inherently hazardous aquatic environment, all reasonable measures must be taken to prevent injury and fatalities. Ensuring all equipment used in operations is fit for purpose is a critical aspect of delivering a safer working environment for our members and employees.

The SLS Inflatable Rescue Boat (IRB) is a motorised inflatable boat crewed by two (2) lifesavers/lifeguards to conduct SLS operations in the surf zone and near shore environments.

The primary purpose of an IRB is to safely, but quickly negotiate the white-water surf zone to reach a person requiring assistance, and to transport them back to shore.

NOTE: For vessels to be used in flood and swift water rescue applications refer to SLS State/Territory centres for vessel requirements.

For the purposes of surf lifesaving, an IRB shall be able to meet the following requirements:

• Be designed to suit a 25-30hp (18-22kW) rated outboard motor and can plane whilst carrying a minimum of four persons each with an average weight of 85kg;

• Have sufficient stowage for essential safety equipment (as listed in Part 1 and Part 2 of this specification);

• Have the capacity to tow a craft of the same or smaller size;

• Have appropriate devices to assist in the lift and maneuverer (e.g. lifting/grab handles);

• Have appropriate mechanisms to stabilise operators in the IRB (e.g. grab handles, crew ropes and foot straps)

SLSA IRB 2015 consists of the following parts, under the general title Inflatable Rescue Boat:

• Part 1: Hull

• Part 2: Accessory Items

• Part 3: Outboard Motor

• Part 4: Approval and Compliance

It shall be noted that the written version of the specification will take precedence over any drawings that may contain opposing measurements or designs. All reasonable attempts to maintain drawings to these specifications will be undertaken by SLSA if any changes occur.

CAUTION: If a corporation supplies goods or services that are not merchantable or unfit for purpose, they may be liable under the Trade Practices Act for damage or loss occurring because of that unfitness.

Section Page reference

4.1

o The fuel tank shall be constructed of a flexible material with the ability to collapse to a flat state when empty.

o The fuel tank shall have a minimum of 4 x 316 stainless steel eyelets, 2 on either side of tank with safety tabs (clip cover tabs) glued above the eyelets and securing the fuel tank to the floor board of the hull.

o All connections, clips and metal materials used in the construction of the fuel tank are to be suitably covered, with coverings made of the same material of the tank.
