Physical Hazards/Ergonomics Flashcards
A worker from the shipping and receiving department who had a vasectomy three days ago, returns to work with a lifting restriction of 25 lbs. The worker’s supervisor consults the OHN, questioning the worker’s ability to perform his job. The first action the OHN should take is to
In order to respond to the supervisor’s concern and to make appropriate recommendations about the worker’s ability to perform his job, the OHN first needs to know the physical demands of the worker’s job. Therefore, the job task analysis should be reviewed.
A worker at a punch press is doing routine maintenance when the press activates and injures the worker’s hand. The OHN should know that one of the causes of this injury was a failure to:
According to the OSHA Standard (29 cfr 1910.147) practices and procedures are required to shut down and lock out machines and equipment before employee’s service or maintain them. In the case, all sources of energy should have been shut down, isolated, blocked, and secured before work began.
An OHN who works in a healthcare facility is reviewing research on safe patient handling. The OHN should be aware that which of the following statements is a myth?
To avoid musculoskeletal injuries, good body mechanics must be used at all times in all phases of providing care and in all phases of a person’s life - not only when lifting patients.
Stretching has long been advocated by PT as a way to improve flexibility and decrease risk of injury. In addition:
Tight muscles have been linked to back pain and shoulder injury.
An example of a slip, trip, and fall hazard specific to healthcare workers is:
Loose cords stretched across operating room
Noise dosimetry at the factory shows a worker exposure of 100 dBA TWA. The ear muffs available in the factory have an NRR of 18 (Noise Reduction Rating). The resulting exposure to an employee wearing the ear muffs would be:
Hearing protection is part of a hearing conservation program, which is required when noise exposure exceeds the action level (85 decibels on the A scale). When using the dBA scale, the noise reduction rating factors must be decreased by 7.
TWA = 100 dbA, muff NRR = 19dB, Estimated Exposure = 100 - (19 - 7) = 88 dBA
