can come from liquids (oil), solids (loose sand, pellets) clutter, debris, cords and hoses, clumsiness.
Hot Items
assume that all metal and plastic components are hot
Always use proper handling devices, such as tongues. Gloves are meant to
protect from accidental contact with hot materials, NOT meant to be used to hold hot items.
Changing tools on machines
Prior to changing the
tooling, make sure that the POWER TO THE MACHINE has been SHUT OFF.
make sure that any equipment is unplugged or main power
disconnected prior to accessing areas to be cleaned
Back and lifting
Heavy objects care when
handling.
When lifting or moving heavy objects, get help from other students and use proper
postures, such as lifting with your legs, not your back.
Lacerations and cuts
Always be careful of instances where sharp edges are present, and do not handle by holding at the sharp edge.
Deburr sharp edges as soon as possible.
Pinching and blunt injuries
Pinching and blunt injuries may occur from dropping a heavy object on fingers, hands, feet, etc.
Pinching may also occur by the operation of certain equipment.
Prior to engaging equipment make sure that your hands, feet, head, etc. are not in the way
Proper footing
When reaching, always make
sure that you can maintain your balance.
Do not lean on tables or cabinets
Hazardous situation
Whenever a hazardous situation is seen, warn others, fix it, and/or report it to the instructor immediately.
If another student is behaving
in an unsafe manner, point this out to him/her and, if necessary, get the instructor involved.
Machining
Make sure that all workpieces, tools, and workholding devices are properly tightened.
Chuck keys may only be on your hand while using it;
otherwise, stowed away in their proper place.
Do not lean on operating machines.
Do not take your eyes from the work piece.
Welding
Gas Explosion
A gas explosion can occur if there is a leak in acetylene gas anywhere in the lab.
Prior to turning on the gas sources make sure that ALL torches, and supplies to stations are off. At the end of lab, also
make sure that all torches and supplies to stations are off.
Foundry
molten aluminum has tendency to stick to skin. Suit up properly
Never set foot on rolling conveyor belt
When shaking out castings, and using cooling water, do not throw casting into water, could lead to steam explosion
Sheet Metal
Dangers
Lacerations and pinched fingers
Shears have ability to amputate fingers.
Power shear and presses will only be used by the professor/technician, or under their supervision.
Plastics
Look out for falling items
IF AN INJECTION DIE OR
COMPONENT IS FALLING DOWN, LET IT FALL. DO NOT ATTEMPT TO CATCH IT. IT IS BETTER TO HAVE
THE TOOL GET DAMAGED THAN HAVE THE STUDENT GET HURT.
Plastics
Lookout for heat
danger using the thermoforming machine is to handle hot plastic with your bear hands. Simply
handle the plastic by the edges and it will not be a problem. Also, beware of elements in the machine
that heat up during operation.
