Handling Blocks and Bricks

Bricklayers and labourers handle thousands of blocks and bricks daily, making it one of the most repetitive manual tasks.
A standard concrete block weighs approximately 20 kg — repeated lifting causes cumulative back injury.
Lightweight aggregate blocks weigh less but are more fragile, crumbling if dropped and creating dust.
Dense concrete blocks used below DPC can weigh over 25 kg each, exceeding safe individual lifting limits.
Brick packs delivered on pallets weigh approximately one tonne and require mechanical offloading.
Repetitive gripping of bricks causes hand and wrist strain, especially in cold and wet conditions.
Brick and block cutting generates silica dust from concrete products and calcium silicate products.
Mechanical aids including block grabs, mini cranes, and mortar silos reduce manual handling significantly.
The Manual Handling Operations Regulations 1992 require employers to reduce the risk so far as practicable.
Work height is important — bricklayers lifting from ground to above shoulder height face maximum strain.

Back injuries	Repetitive lifting of blocks weighing 20 kg+ is the single biggest cause of back injury among bricklayers.
Cumulative damage	Daily handling of thousands of units causes musculoskeletal damage that worsens over a career.
Silica dust	Cutting concrete and calcium silicate blocks releases respirable crystalline silica that causes lung disease.

Do

Don't

Use mechanical aids such as block grabs and mini cranes for moving packs and pallets
Keep block and brick stacks at waist height to avoid lifting from ground level
Use a scaffold or platform so the working height avoids above-shoulder lifting
Rotate tasks between laying, cutting, and labouring to vary the physical demands
Cut blocks using wet saws or with dust extraction and RPE to control silica dust
Wear gloves to improve grip and protect hands from rough block surfaces
Limit the number of heavy blocks carried per trip to reduce cumulative strain
Take regular breaks from repetitive lifting to allow muscles to recover
Report back, wrist, or hand pain early — do not wait until the injury is severe
Plan material deliveries so blocks and bricks are placed near the point of use

DON'T carry more blocks than you can safely control with good posture
DON'T lift dense concrete blocks weighing over 25 kg without team assistance or aids
DON'T bend at the waist to pick up blocks from ground level — bend your knees
DON'T lay bricks from above shoulder height without raising the working platform
DON'T cut blocks without dust extraction, water suppression, and RPE
DON'T stack blocks or bricks higher than a stable height on the scaffold platform
DON'T unload pallet packs by hand — use a mechanical offloader or forklift
DON'T carry blocks up ladders — use a hoist or material lift instead
DON'T work through pain in your back, hands, or wrists — report it promptly
DON'T store materials far from the work face, forcing long carrying distances
