Biomechanics
The study of the mechanical laws relating to the movement or structure of living organisms. In manual handling, biomechanics helps us understand how forces affect the body during lifting and handling tasks.

How to use this glossary
The vocabulary every Manual Handling learner should know.
Manual Handling has a specialist vocabulary. Acronyms such as TILE, MSD and WRULD, anatomical terms like lumbar and lordosis, and regulatory language around risk assessment and safe systems of work all appear in the UK Manual Handling Training environment.
This glossary collects the most important terms in one place, with clear, plain English definitions aligned to HSE guidance and current UK workplace practice.
Use this page as a quick reference while you work through the Manual Handling Course, prepare a risk assessment, or brief a team on safe lifting.
Every definition here is used inside our HSE compliant course and on our wider Manual Handling guides. Scroll below for the full A to Z list.
A to Z glossary
Manual Handling definitions
Every essential Manual Handling term, grouped alphabetically for quick reference.
Letter B
Terms starting with B
Base of Support
The area beneath a person that includes every point of contact with the supporting surface. A wider base of support, feet shoulder-width apart, provides greater stability during lifting.
Letter C
Terms starting with C
Centre of Gravity
The point at which the entire weight of a body may be considered as concentrated. Keeping your centre of gravity low and over your base of support improves stability when lifting.
Cumulative Trauma
Injury that develops gradually over time due to repeated small stresses rather than a single incident. Many manual handling injuries are cumulative rather than acute.
Letter E
Terms starting with E
Ergonomics
The science of designing and arranging things so people can use them efficiently and safely. Ergonomic workstation design reduces manual handling risks.
Environment
In the TILE assessment, the E stands for Environment, the physical conditions where manual handling takes place, including space, flooring, lighting, and temperature.
Letter H
Terms starting with H
HSE
Health and Safety Executive, the national body in the UK with responsibility for securing health and safety at work. The HSE enforces health and safety legislation and provides guidance on manual handling.
Hazard
Something with the potential to cause harm. In manual handling, hazards include heavy loads, awkward postures, repetitive movements, and poor environmental conditions.
Letter L
Terms starting with L
Load
In the TILE assessment, the L stands for Load, the object being handled. Assessment considers the load's weight, size, shape, stability, grip points, and contents.
Lumbar Region
The lower back region of the spine, consisting of the five lumbar vertebrae. This area is most vulnerable to manual handling injuries.
Lordosis
The inward curve of the lumbar spine. Maintaining the natural lordotic curve during lifting helps protect the spine from injury.
Letter M
Terms starting with M
Manual Handling
Any transporting or supporting of a load by one or more employees. This includes lifting, lowering, pushing, pulling, carrying, moving, holding, or restraining objects or people.
MSD
Musculoskeletal Disorder, injuries and disorders affecting muscles, nerves, tendons, joints, cartilage, and spinal discs. Manual handling is a leading cause of MSDs.
Mechanical Advantage
Using the body's natural levers and fulcrums efficiently to reduce effort. Proper technique maximises mechanical advantage when lifting.
Letter P
Terms starting with P
Posture
The position and alignment of the body. Good posture during manual handling means maintaining the natural curves of the spine and avoiding awkward positions.
Power Zone
The area between mid-thigh and mid-chest height where lifting is safest and most efficient. Loads should be kept in this zone when possible.
Letter R
Terms starting with R
Risk Assessment
The process of identifying hazards, evaluating the risk of harm, and determining appropriate control measures. Employers must conduct risk assessments for manual handling tasks.
Repetitive Strain
Injury caused by repeated movements that stress the same muscles, tendons, or joints. Repetitive manual handling without adequate rest can cause cumulative damage.
Letter S
Terms starting with S
Spinal Disc
The cushion-like pads between vertebrae that act as shock absorbers. Improper lifting technique can damage or rupture spinal discs.
Safe System of Work
A procedure that results from systematic examination of a task to identify all hazards and defines safe methods to ensure hazards are eliminated or risks minimised.
Letter T
Terms starting with T
TILE
A risk assessment framework for manual handling: Task, Individual, Load, Environment. Assessing these four factors helps identify and control manual handling risks.
Task
In the TILE assessment, the T stands for Task, the activity being performed. Assessment considers movements required, distances, frequency, and duration.
Team Lifting
Two or more people working together to move a load that is too heavy or awkward for one person. Requires coordination and clear communication.
Letter W
Terms starting with W
Warm-up
Preparatory activities that increase blood flow to muscles and improve flexibility before physical work. Warming up reduces injury risk during manual handling.
Work-Related Upper Limb Disorder (WRULD)
A range of conditions affecting muscles, tendons, and nerves in the hands, wrists, arms, shoulders, and neck. Also known as repetitive strain injury (RSI).
Manual Handling terminology explained in depth
Knowing the correct Manual Handling vocabulary is more than an academic exercise. It is the difference between a confused team and one that can apply HSE guidance confidently on the shop floor, the ward, the warehouse or the building site.
TILE, the UK standard risk framework
The most frequently used acronym in UK Manual Handling is TILE. It stands for Task, Individual, Load and Environment, the four factors every employer must consider when assessing a handling operation. TILE underpins the Manual Handling Operations Regulations 1992 and is built directly into our course and assessment.
MSDs and WRULDs, the injury categories
An MSD (Musculoskeletal Disorder) is the broad category of injuries covering muscles, tendons, joints, nerves and spinal discs. A WRULD (Work-Related Upper Limb Disorder) is a specific type of MSD affecting hands, wrists, arms, shoulders and neck, often caused by repetitive manual handling without adequate recovery.
Anatomy terms that matter
The lumbar region, the lower five vertebrae of the spine, carries most of the load during lifting and is the most commonly injured area in UK workplaces. Maintaining lordosis, the natural inward curve of the lumbar spine, is a core principle of safe lifting technique covered in the course.
The power zone and centre of gravity
The power zone, between mid-thigh and mid-chest height, is where the body can lift most safely and efficiently. Keeping the centre of gravity low and over a stable base of support dramatically reduces strain on the spine.
For the full practical application of these terms, see the safe lifting techniques guide, or enrol in the Manual Handling Course to learn every concept in context.
FAQ
Manual Handling terminology questions
The three questions we are asked most often about Manual Handling vocabulary.
What is the TILE framework in manual handling?
TILE is a risk assessment framework covering Task, Individual, Load, and Environment. It is the standard UK method for evaluating any manual handling activity before it is carried out.
What does MSD stand for in manual handling?
MSD stands for Musculoskeletal Disorder, a group of injuries affecting muscles, tendons, joints, nerves and spinal discs. Poor manual handling is a leading cause of MSDs in UK workplaces.
What is the difference between a hazard and a risk?
A hazard is anything with the potential to cause harm, such as a heavy load or awkward posture. A risk is the likelihood that the hazard actually causes harm in a given situation, which is what a risk assessment is designed to measure.
