What do the Manual Handling Regulations require on a building site?
The Manual Handling Operations Regulations 1992 require employers to avoid hazardous manual handling where reasonably practicable, assess what cannot be avoided and reduce the risk of injury as far as reasonably practicable. The law sets no weight limit.
The three duties
Regulation 4 gives employers a sequence. First, so far as reasonably practicable, avoid the need for workers to handle loads in a way that risks injury. Where that is not possible, make a suitable and sufficient assessment, reduce the risk to the lowest level reasonably practicable, and give workers general indications of the weight of each load and, where reasonably practicable, precise information on it and on the heavier side of an off-centre load.
The assessment must be reviewed if it may no longer be valid or the work changes significantly. Workers must make full and proper use of the system of work they are given (regulation 5). The Regulations apply in Great Britain.
Assessing it: task, individual, load, environment
Schedule 1 to the Regulations lists what the assessment must consider: the task, the load, the working environment and individual capability. Many people remember them as TILE (task, individual, load, environment), a common memory aid. The Schedule itself asks questions such as:
- Task: is the load held away from the body, with twisting, stooping or reaching upwards, long lifts or carries, frequent effort, too little rest or a rate of work set by the process?
- Individual: does the job need unusual strength, create a risk for someone with a health problem or who is pregnant, or need special training?
- Load: is it heavy, bulky, hard to grip, unstable, sharp or hot?
- Environment: is there too little room, an uneven or slippery floor, changes of level, extreme heat or cold, wind or poor light? Clothing or PPE that restricts movement counts too.
HSE's MAC tool helps rank lifting, carrying and team tasks, and its RAPP tool covers pushing and pulling.
Weights: guidelines, not limits
HSE does not recommend weight limits, and it says there is no safe weight. Its leaflet does give guideline filter figures for lifting and lowering, which depend on hand height and distance from the body, to help sort low-risk tasks from those needing a closer look. HSE stresses that these are filters and not safe limits, and that even a task inside them should be avoided or eased where reasonably practicable.
A figure HSE does use for blocks is 20 kg, as a warning point and not a legal limit. It says repeated single-handed handling of masonry units, especially those over 20 kg, risks injury, that a block under 20 kg that meets the design is usually available, and that two-person laying of blocks over 20 kg is no longer recommended.
Blocks, kerbs, plasterboard and cement
- Blocks: order the lightest that meets the design, talk to the designer about laying thinner dense blocks flat, use trench blocks with handholds, and keep them dry. Do not load out by hand, deliver close to the point of use, lay between chest and knee height, and do not carry blocks up ladders.
- Kerbs: HSE says a concrete kerb can weigh more than 70 kg and that you should not be lifting kerbs in most circumstances. It points to slip-formed, plastic, hollow or lightweight kerbs, and to vacuum lifters or mechanical grabs. Manual laying is for very short lengths only.
- Plasterboard: special thermal or acoustic boards can weigh up to 50 kg each. Ask suppliers to mark the weight, load out by telehandler or trolley before openings close, and use ceiling lifts, props and board tables. HSE calls a two-person carry a last resort.
- Cement and aggregates: HSE suggests ordering smaller bags, or using pre-mixed mortar, a batch mix silo or a concrete pump instead of mixing on site.
Lifting aids and planning
HSE's first answer is to mechanise: hoists, telehandlers, cranes, pallet trucks, sack barrows and trolleys, and deliveries made straight to where the material is used. Keep heavy items at waist height, tidy the route, rotate workers and keep materials dry so they do not gain weight. Training in handling technique is worth having but does not replace these controls. Lifting equipment needs thorough examination.
