Patient transfer techniques that reduce strain and injury risk include: neutral trunk posture, coordinated knee flexion, assistive device use, and push/pull assignments based on body height and weight.

Forward (day-to-night) rotations significantly increase fatigue, degrade sleep, and impact vigilance and delay adaptation; for operations, minimize rotating shifts and prioritize fatigue risk management for safety-critical performance.

A 25-experiment review found mixed evidence for Tall Man Lettering. Some accuracy improvements, but varies by: user background, drug familiarity, orthographic similarity, position, exposure time.

Experienced Fast Rescue Craft operators had higher situation awareness than novices in a search and rescue simulation due to their ability to better predict future events (Level 3 Situation Awareness).

Passive exoskeletons prevented low-back tissue creep and reduced muscle strain during prolonged stooping, helping maintain spinal stability and lowering potential risk of low back pain development.

The Critical Decision Method was used to develop a cue inventory and decision map for improving firefighter decision-making, safety protocols, and training design.

HRV and accelerometer data can distinguish mental from physical stress, with combined stress producing stronger, more persistent physiological responses in ICU nurses.

Patients’ fall risks are more intrinsic at long-term care facilities/hospitals (e.g., medications, illness, cognitive deficits) and extrinsic at home healthcare settings (e.g., inadequate assistive devices).

Avoiding low back flexion reduces spinal flexion without reducing strength, but high individual variability shows simple directives are insufficient. Personalized coaching is needed to ensure safe and effective lifting performance.

Usability of handles was studied with lifting in a grocery store. The most preferred and best evaluated design are classic rounded rectangular handles, middle position, set at 0 degrees angle. Curved handles are less preferred and holes are least preferred; and both distribute weight less evenly.
