Understanding Hazards Flashcards

What is a 'hazard checklist' and when should it be used?

Answer: A structured list of common hazards used during workplace inspections to ensure systematic identification of potential dangers

A hazard checklist is a structured tool listing common hazard categories relevant to a workplace or activity. It is used during inspections and risk assessments to ensure a systematic, comprehensive approach to hazard identification and reduce the chance of overlooking significant hazards.

What is 'HAVS exposure action value' under the Control of Vibration at Work Regulations 2005?

Answer: An 8-hour exposure of 2.5 m/s² A(8) for hand-arm vibration

The daily exposure action value for hand-arm vibration is 2.5 m/s² A(8). Above this level, employers must introduce measures to reduce exposure. The exposure limit value is 5 m/s² A(8), which must not be exceeded.

What is 'hazardous manual handling'?

Answer: The transporting or supporting of a load by bodily force where there is a risk of injury

Manual handling means transporting or supporting a load by hand or bodily force, including lifting, lowering, carrying, pushing and pulling. It is hazardous when the task, load, working environment, or individual capability creates a risk of injury, particularly musculoskeletal injury.

What factors increase the risk of manual handling injuries?

Answer: The task (posture, repetition), the load (weight, shape, grip), the environment (space, floor), and individual capability

Manual handling risk depends on four factors (TILE): Task (twisting, stooping, repetition, distance), Individual (strength, health, training), Load (weight, bulky, unstable, hard to grip), and Environment (space constraints, floor condition, temperature, lighting).

What is 'upper limb disorder' (ULD)?

Answer: A range of conditions affecting the hands, wrists, arms, elbows, shoulders and neck, often from repetitive work

Upper limb disorders (ULDs) are a group of conditions affecting the soft tissues, muscles, tendons, and nerves of the hands, wrists, arms, elbows, shoulders and neck. They are often associated with repetitive or sustained movements, forceful exertions, awkward postures, and vibration.

What workplace activities can expose workers to biological hazards?

Answer: Agriculture, healthcare, waste management, water treatment, construction (soil disturbance), and any work involving contact with people, animals or contaminated materials

Biological hazards exist in many workplaces: healthcare (blood-borne viruses), agriculture (zoonotic diseases), waste management (infectious waste), water treatment (Legionella), construction (soil bacteria, Weil's disease), laboratories, veterinary work, and any workplace where workers contact bodily fluids.
