Task Description

• Workers are required to clean off rust and old layers of lead-based paint (in encapsulated area) to prepare surface for painting.
• Depending on area of work and cleaning requirement, workers use 3 types of hand tools: needle scaler gun (metal rods pulse on surface to break down rust), whizzer wheel buffer or a CP (grinder with wire).
• Workers are are required to clean all surfaces that are to be painted and may involve working from step ladders, mini scaffolds, laying on the ground and/or crawling into confined areas.
• Workers are required to wear PPE (anti-vibration gloves) due to vibration exposure from tools.
• Workers self monitor tolerance of working position and vibration exposure and take breaks as needed.
• Once an encapsulated area is cleaned, waste is vacuumed and deposited in bins.
• Vacuum and bins are winched to and from the site by Riggers.

Task Description

• Where possible, workers will use pressurised sandblaster to blast off old paint and rust (space permitting) in a fully contained worksite (ie full encapsulation has been set up).
• Blaster is connected to large pipes (that are fed into encapsulated area). Workers are required to hold the hand held blaster pipe whilst bracing with upper body to counteract the push back pneumatic force (blaster emits 100 psi pressure).
• Certain job sites and bridge structures require workers to crawl into tight spaces, , bend down, lay on the floor or work in an overhead position. Pipe is held in various positions (from ground height, to waist to above head) to access and clean various surfaces and areas.
• Workers conduct task in presence of another worker to ensure safe operation of sandblaster, and task rotation as needed. Secondary worker also has access to dead man's switch for blasting pipe as a safety precaution.
• Vacuum for blasting waste connects to steel pipes to the vacuum unit in compound yard below, where waste is collected and transferred into waste drums for safe disposal.

Task Description

• Workers are required to apply 4 coats of paint for all surfaces of the bridge (2 primers, 1 intermediate and 1 top coat), as well as striping/cutting in. Each coat must dry for 24 hours before the next is applied.
• Workers only begin task once full encapsulation/containment has been established. The undercoat is applied by brush and rollers, and only the intermediate and top coat can be applied by spray machine(this is typically winched to the work area by Riggers during containment set up).
• Workers conduct task at variable heights and positions depending on surface/area to be painted.
• Areas with limited/restricted access may required bending, squatting, crawling or straddling steel structures.
• Workers push spray machine with low force, uneven surfaces require greater force to manoeuvre. Workers have variety of PPE to chose from for personal fit and comfort.

Task Description

• Painters are required to set up work area on various areas on/within the bridge with ply panels or full encapsulation before any paint cleaning begins (scaffolding is already set up by Riggers).
• Plywood (5-25 mm) is stored in pylon and are cut to required size before being transported to work area.
• Encapsulation must be set up before any paint blasting is conducted. Monoflex plastic used (2m x 45m and 4m x 25m, 15kg), this is carried to job sites by 2 workers.
• Containment and Disassembly may take up to 2 weeks each, this can vary depending on the complexity of the job site.
• Once containment is set up, workers are not required to wear harnesses and work may begin.
• Larger paint tins are usually transported to work area right after containment has been set up.

Task Description

• Workers typically access work site via catwalk under bridge from North or South pylon, distances travelled will vary depending on work site location. Workers may also drive light vehicles between north and south pylons depending on worksite location.
• Workers must navigate through tight spaces and are required to crawl, climb ladders and stairs, and step over beams/rails to access certain sites.
• Due to the fixed structures of the bridge, workers must maintain vigilance when accessing and navigating to and from work areas and be mindful of trip hazards at ground and obstacles at head height.
• Workers may be required to carry small paint pots (max 3kg) attached via lanyard.
• Personal tools and required PPE are either worn or carried by workers in backpack.
