A process for effectively planning workplace safety and health.

A combination of likelihood and severity.

Calculated by multiplying likelihood and severity of a risk.

Probability of a risk occurring.

Potential harm or damage if a risk occurs.

Unforeseen events causing harm within a workspace.

Lowering the workload capacity for more hazardous equipment.

Prioritizing health and safety of workers by employers.

Materials like synthetic rubber, nylon, PVC, and polypropylene, offering lightweight and adaptable properties for various industrial uses.

Substances added to polymers to modify their characteristics, such as plasticisers for flexibility and stabilisers for durability.

Common uses in lifting equipment include roundslings, flat webbing slings, ropes, gears, bushes, and sheaves due to their strength and flexibility.

Used with latex and rubber to create wear seals, pressure seals, and oil seals, providing essential protection for moving parts.

Materials from grasses and leaves, spun into ropes and used traditionally for making fibre rope slings, though less prevalent today.

Traditional sling made from natural fibre ropes, hand-spliced into specific lengths for lifting.

Materials like manila, hemp, and sisal are frequently used for making fibre rope slings.

Process of heating and cooling metals to change their structure and properties, making them suitable for specific applications.

A systematic process to identify potential hazards in a workplace, assess associated risks, and implement preventive measures.

A common framework for managing workplace risks, involving identifying hazards, determining who might be harmed, evaluating risks, recording findings, and reviewing these findings regularly.

The first step in risk management, involving listing all potential dangers in the workplace.

Determining the individuals or groups who are most likely to be affected by identified hazards.

Assessing the severity and likelihood of each identified hazard, deciding how urgent each risk is.

Documenting the findings of the risk assessment and implementing necessary control measures.

The final step, where the risk assessment is revisited to check for any new hazards or changes requiring updates.

Potential dangers arising from changes in the workplace, including new procedures, equipment, products, or modifications.

In lifting, we often consider weight and force to be equal and measured in the same units.

The force used to lift a load in a lifting machine.

The force or weight being lifted.

The ratio of the load lifted to the effort applied in a machine.

A state where the effort and force in a machine are equal.

Increasing the lines of cable on a winch increases the load it can pull.

The point where effort is applied to lift a load, creating a force.

The maximum safe weight a lifting device can handle.

Techniques used to find cracks and other surface defects in materials. Common methods include dye penetrant, magnetic particle, eddy current, radiography, and ultrasonic.

A method that identifies surface cracks by using a dye that penetrates the crack and then is revealed with a developer solution.

A technique that uses magnetic fields to detect surface cracks in ferrous materials. Iron particles adhere to magnetic field distortions caused by cracks.

Utilizes electromagnetic fields to detect flaws like cracks, corrosion, and material degradation in conductive materials.

Uses X-rays or gamma rays to create images of the internal structure of materials, revealing cracks and defects.

Uses sound waves to detect internal flaws in materials. The reflection of sound waves reveals defects like cracks and voids.

Basic crack detection methods are often used for general lifting equipment, while more detailed methods are used for high-value items and safety-critical applications.

Basic crack detection methods are relatively inexpensive, while more detailed methods require advanced training and specialized equipment, increasing the cost.

A measurement of a material's resistance to indentation, often used to assess lifting equipment's quality after heat treatment or when used in harsh environments.

A common method of hardness testing in the lifting equipment industry, where a hardened steel ball indents the material under a specific load.

A way to measure a material's resistance to sudden shock or impact, typically performed using the Charpy or Izod method.

Measures the energy absorbed by a material when fractured by a swinging pendulum, indicating its toughness.

Similar to the Charpy Test, but the specimen is clamped vertically and broken by a swinging pendulum.

A simple test where the material is bent at a specific point, assessing its flexibility and ductility without breaking.

The three basic methods are Vickers, Brinell, and Rockwell.

The two common impact test methods are Charpy and Izod.
