Final answer:
Ignoring the necessity to break up repetitive motion tasks and relying solely on personal protective equipment are ineffective methods for reducing ergonomic injuries. These approaches fail to address the underlying causes of musculoskeletal disorders.
Step-by-step explanation:
Two ineffective methods of reducing ergonomic injuries in the workplace include not addressing repetitive motion tasks and relying solely on personal protective equipment (PPE) without implementing environmental or process changes.
Ignoring repetitive motion such as typing or assembly line work, without incorporating breaks or variations in tasks, can lead to musculoskeletal disorders despite any other precautions taken. Simply wearing PPE like gloves or back belts does not prevent injuries if the root cause, like constant standing or machine noise, is not dealt with. For instance, while back belts may offer some support, they can create a false sense of security and do not remove the need for proper lifting techniques or ergonomic workstation design.
Additionally, cultural practices that involve the acceptance of using harsh disciplinary measures against workers are not only ineffective but can exacerbate physical and psychological harm, causing further issues rather than preventing injuries.
