Class 3: MSIP & WHMIS Flashcards
body alignment
the longitudinal position of a bone or limb
balance
stability, steadiness
base of support
the part of an object or person in contact with its supporting surface and the area between the parts. when standing on two feet, for example, the feet and the area between the feet are the base of support
body mechanics
how we hold our bodies when we sit, lift, stand, carry, bend, and sleep
centre of gravity
the point at which an object or persons weight is centered and balanced. in an adult, this point is in the centre of the pelvis, behind the umbillicum (belly button). half weight above, half below. evenly distributed on both left and right side as well.
friction
rubbing, or the force that opposes motion
ergonomics
applied science that is concerned with designing and arranging things that people use so that people and things interact most efficiently and safely
gravity
the force that pulls objects towards the earth
momentum
a property of a moving body that is functioning with mass and velocity
posture
the carriage of the body as a whole, the attitude of the body, or position of limbs
vertebrae
the bony blocks that make up the spine
disc
the jelly like substance between vertebrae
ligaments
bands of tough tissues that connect bones. in the back, ligaments, along with muscles, keep the vertebrae in good alignment. a common cause of back pain is over usage of the ligaments
line of gravity
an imaginary line passing vertically through the center of gravity to the base of support. in a person who is standing, this line runs from the top of the head, through the center of gravity, to the area between the feet
lever
a rigid bar that moves on fixed points.
example: elbow on the bed is a fixed point
MSDS
material safety data sheet
STABLE
S- maintain natural curve of the spine T-avoid trunk twisting A-arms close to body B-maintain a broad base of support L-use your legs E-Evaluate. make sure you evaluate the load, the environment, your abilities and limitations before starting any activity
