4 Questions
Match the following manual handling tasks with their potential risk of injury:
Lifting = Risk of strains and sprains to the lower back Climbing = Potential risk of musculoskeletal disorders (MSDs) Pushing = May lead to injuries to the back and skeletal systems Pivoting = Pose the risk of injury to the back and other skeletal systems
Match the following workplace environments with the presence of manual material handling (MMH):
Offices = Manual material handling tasks can be found Heavy industrial facilities = Involves manual handling of materials Recreational atmospheres = Exposure to manual lifting of loads Manufacturing facilities = Tasks such as lifting, pushing, and pivoting are common
Match the following terms with their definitions:
Musculoskeletal disorders (MSDs) = Involving strains and sprains to the lower back, shoulders, and upper limbs Manual material handling (MMH) = Involves the use of the human body to lift, lower, carry, or transfer loads Hazards and injuries = Manual handling of materials can lead to potential risks and physical harm Manual handling of loads (MHL) = Involves lifting, lowering, carrying, or transferring loads using the human body
Match the following statistics with their descriptions:
U.S. Department of Labor study published in 1990 = Back injuries accounted for approximately 20% Average person's exposure to manual lifting of loads = Occurs in the workplace, recreational atmospheres, and even in the home Types of injuries from manual material handling = Strains and sprains to the lower back, shoulders, and upper limbs Scope of manual material handling tasks = From offices to heavy industrial and manufacturing facilities
Study Notes
Manual Handling Tasks and Injury Risks
- Lifting heavy objects: risk of back strain and musculoskeletal disorders
- Repetitive tasks: risk of repetitive strain injuries and carpal tunnel syndrome
- Bending and twisting: risk of back strain and herniated discs
- Pushing and pulling: risk of shoulder and back strain
Workplace Environments and MMH Presence
- Warehouses: high presence of MMH due to frequent loading and unloading of goods
- Construction sites: high presence of MMH due to manual handling of building materials
- Offices: low presence of MMH due to minimal manual handling of objects
- Healthcare facilities: moderate presence of MMH due to handling of patients and equipment
Manual Material Handling Terms and Definitions
- Ergonomics: the study of designing tasks and environments to reduce manual handling risks
- MSD: Musculoskeletal Disorder, a type of injury caused by manual handling
- Manual material handling (MMH): the use of physical effort to move or handle objects
- Hazard: a situation or object that has the potential to cause harm
Manual Handling Statistics and Descriptions
- 30% of workplace injuries are caused by manual handling: highlighting the importance of MMH safety
- 60% of MSDs are caused by MMH: emphasizing the need for proper ergonomics
- 1 in 5 workers experience MMH-related injuries annually: emphasizing the need for regular training
Test your knowledge of safe manual handling practices with this quiz on Manual Handling of Loads (MHL). Learn about hazards, injuries, and proper body mechanics to protect yourself from potential harm in the workplace and at home.
