MPG Laboratory Safety Procedures--Chemical Safety
Compressed gas cylinders can blow up and act very much like missiles, if the cylinder falls over
and the valve is damaged.
• All cylinders should be turned off when not in use
• All cylinders should be attached to a cylinder clamp or stored on a gas cart.
MPG Laboratory Safety
Procedures--Chemical
Safety
Flammable liquids can burn or explode.
• Larger quantities of flammable liquids should
be stored in metal chemical cabinets.
• There are such cabinets in SER 217, SER 21
and the Machine Shop.
MPG Laboratory Safety Procedures--Chemical Safety
Laboratory chemicals can cause various levels on irritation to users.
•
•
•
•
•
•
Always use proper Personal Protection Equipment (PPE). This almost always include nitrile gloves.
Eye ware and lab coats are suggested for longer exposure and more hazardous chemical.
Chemicals should be used in hoods whenever possible as a precaution.
Wash your hands and all equipment used after use.
Larger quantities of hazardous chemicals should be stored in metal chemical cabinets.
There are such cabinets in SER 217, SER 21 and the Machine Shop.
MPG Laboratory Safety Procedures--Chemical Safety
Vacuum Parts Cleaning Procedures
•
•
•
•
•
•
If object is visibly dirty, clean with dish soap and water first.
Chemical cleaning is most often done in an ultrasonic bath in a hood.
• Put the object in a beaker
• Fill the beaker with dichloromethane to just above the object
• Place the beaker in the ultrasonic cleaner
• Fill the ultrasonic (not the beaker) with water up to the same level as the solvent
• Turn on the ultrasonic cleaner and leave for 10-30 minutes
• When done, take out the object with clean tweezers. Alternately, objects can be put in the beaker inside a tea strainer.
• Use the funnel and pour the used solvent into the used container for waste.
Part with significant contamination (e.g., those coming from a machine shop) should be cleaned with a dichloromethane bath.
• This solvent is the nastiest chemical we use on a routine basis. Treat it accordingly!
• Use the rubber (not nitrile) gloves for the dichloromethane
• Dichloromethane evaporates quickly and can cause frost accumulation. Covering the beaker with Al foil minimizes this
Repeat the above with Acetone and then Methanol.
• You don’t have to use rubber gloves with these, but use the nitrile or latex gloves if you’re touching the object being
cleaned.
The solvents we use are in bottles stored underneath the hoods. If those bottles are empty, fill them with the large canisters
stored in SER 16 (Dark Room).
Used solvents are to be put in chemical disposal bottles. Waste is stored in SER 16 (Dark Room) prior to Hazardous Waste pick up.
MPG Laboratory Safety Procedures--Chemical Safety
Handling Lead can be hazardous.
• MPG deals with bulk lead as shielding (and door stops).
• Exposure to lead through handling lead or ingesting lead is an know hazard.
• Always use proper Personal Protection Equipment (PPE). This almost always include
nitrile gloves.
• Wash your hands and all equipment used after use.
• For more information see http://rgs.usu.edu/ehs/lead/
MPG Laboratory Safety Procedures--Machine Shop Safety
• Use of the Machine Shop Requires a separate training/lecture from JR
•

•
Do not do anything stupid!
Do not do anything you do not know how to do!
Leave the door open
Have someone around (to haul you to the hospital)
Clean up after you use the shop
MPG Laboratory Safety Procedures--Laser/UV Safety
The main hazards are
• Lasers (we do not have any lasers with high
enough ratings to require special training or
safety procaustions)
• UV light sources
Always wear eye protection when using the
intense UV sources
MPG Laboratory Safety Procedures--Electrical Safety
• The primary electrical hazards are:
• AC power
• Use caution with open wiring
• Periodically inspect for frayed cabling
• High voltage equipment
• Do not disable safety interlock without careful though
• Have a second person in the room when working with open HV
MPG Laboratory Safety Procedures--Radiation Safety
• Use of the Radiation Sourses requires separate
• Do not open the Sr90 source without a trained person with you
• Avoid prolonged exposure to the Sr90 source in SER 13
• In general, stay outside the marked area when the Sr90 source is in use (red
light flashing)
MPG Recycling/Materials Disposal
MPG strongly advocates recycling of all possible materials
Paper/Cardboard
Dispose of clean dry paper/cardboard in the blue bins in each lab and by the elevators.
Custodians will not empty these bins. Take stuff to loading doc occasionally.
Plastics
Dispose of clean bottles in the blue bins in each lab and by the elevators.
Batteries (http://rgs.usu.edu/ehs/lead/
Dispose of in boxes in each lab.
Dispose of in the box in each lab and in SER 16 (Dark Room).
Chemicals (http://rgs.usu.edu/ehs/radiological-waste )
Dispose of in the bottles in each lab. There are separate bottles for acetone, methanol, and trichloromethane.
Empty these bottles into larger containers in SER 16 (Dark Room).
Notify JR or Brian when large bottles are full, so they can arrange hazardous waste pickup.
Oils
Dispose of into larger containers in SER 16 (Dark Room).
Notify JR or Brian when large bottles are full, so they can arrange hazardous waste pickup.
Mercury (http://rgs.usu.edu/ehs/mercury-thermometer-replacement-program/ )
Dispose of in container in SER 16 (Dark Room).
Fluorescent light bulbs
Dispose of in container in SER 16 (Dark Room).
Broken glass
Dispose of in container in SER 16 (Dark Room).
Cu
Dispose of in boxes in each lab.
Empty these boxes into larger containers in SER 16 (Dark Room).
Other metals Batteries (http://rgs.usu.edu/ehs/lead/
