| Chemicals -
general or specific (not part of Space Registration) |
| Gas Cylinders |
Any container that is used to contain gases at higher than atmospheric
pressure.
|
| Toxic Gases |
Gases such as arsine, phophine, silane, diborane, germine, hydrogen selenide
that are poisonous and require special ventilation and monitoring systems.
|
| Hydrofluoric acid (HF) |
An especially toxic acid that requires users to have a specific antidote
(calcium gluconate) on hand in the laboratory.
|
| Perchloric acid & organic peroxides |
Chemicals that may form explosive compounds or otherwise become unstable
and therefore require special precautions.
|
| Combustible metals |
Metals in a form (typically powder or fine particles or thin sections)
that allows them to ignite easily in the presence of air and water. Some
combustible metals cannot be extinguished with water and require special
extinguishing powders (for Class D fires), or special inerting gases.
|
| Chemical wastes |
| Satellite accumulation area |
The temporary storage of waste materials at the point of generation.
|
| Less than 90-day storage area |
An area where RCRA chemical waste may be stored for up to 90 days. This
type of storage area does not have to be at the point of generation. All
less than 90-day storage areas must be established and managed by the EHS
Environmental Management Program.

| Biological (not part of Space Registration) |
| Autoclave |
|
| Radiation sources
(not part of Space Registration) |
| Radioactive material |
Substances that emit ionizing radiation. Massachusetts DPH licenses radioactive
material use. Any lab using radioactive materials must have a current authorization
issued by the MIT Radiation Protection Committee.
|
| X-Ray Machine |
A device that emits ionizing radiation. Used as an analytical tool for
x-ray fluorescence, diffraction and irradiation work. Also includes diagnostic
machines used in medical, dental, and veterinary areas.
|
| Accelerator |
A device that emits ionizing radiation by the acceleration of particles.
Typically very high radiation doses associated with this equipment.
|
| Non-ionizing radiation sources (not part of Space Registration) |
| Class 3b and 4 lasers |
Lasers and laser systems that require registration with the Radiation
Protection Program and the Massachusetts DPH. All lasers are required by
regulation to be labeled with their class.
|
| RF Sources |
Non-contained radio frequency sources such as radar and microwave. This
does not include microwave ovens, cell phones, or other such consumer devices.
|
| Magnets |
Devices capable of producing static magnetic fields in excess of 5 gauss
in spaces accessible to workers. Typical devices are nuclear magnetic resonance
(NMR) spectroscopy and magnetic resonance imaging (MRI) systems.
|
| Safety equipment
(not part of Space Registration) |
| Fumes hood |
|
| Safety shower |
|
| Eye wash station |
|
| Fire extinguisher |
|
| Spill response material |
|
| Other (not part
of Space Registration) |
| Exposed high voltage |
Exposed wiring and equipment greater than 600 volts.
|
| Confined space |
Spaces that are large enough and so configured that an employee can bodily
enter and perform assigned work; and have limited or restricted means for
entry or exit (for example, tanks, vessels, silos, storage bins, hoppers,
vaults, and pits are spaces that may have limited means of entry); and are
not designed for continuous employee occupancy.
|
| Ergonomics hazard or lifting |
excessive repetitive motion or awkward positions like computing, pipeting
or microscopy
|
| Noise > 85 dB |
Regular or continual noise sources in a room that are loud enough to require
people to raise their voices to be understood by another person standing
at a distance of 3 feet or less.
|
| Cranes/lifts/hoists |
Machine for lifting and lowering a load and moving it horizontally, with
the hoisting mechanism an integral part of the machine. Cranes whether fixed
or mobile are driven manually or by power.
|
| Pressure vessels |
Vessels containing a volume more than 120 gallons of water under pressure,
having internal or external pressure in excess of 15 psi, and an inside
diameter of more than 6 inches.
|
| Heat stress |
Operations involving high air temperatures, radiant heat sources, high
humidity, direct physical contact with hot objects, or strenuous physical
activities have a high potential for inducing heat stress in employees engaged
in such operations. At MIT, potential heat stress areas are steam tunnels
and areas near furnaces or boilers at CUP.
|
| Powered industrial vehicles |
Fork lift trucks, tractors, platform lift trucks, motorized hand trucks,
and other specialized industrial trucks.
|
| Powered machine tools |
Machines and tools such as saws, lathes, drill press, milling machines
|
| Cryogenics |
Fluids existing at temperatures -100° F (-60° C) to -460° F (-266° C),
low enough to damage body tissues after prolonged contact with the fluids,
surfaces cooled by fluids, or evolving gases.
|
| Vacuum oven |
Oven or furnace where a vacuum pump is used to displace oxygen and, in
most cases, to reduce the water vapor content or dew point as well.
|
| Hot work area |
Area where welding, cutting, brazing, using open flames or similar operations
are performed.
|
| We dropped this from the list because
it is so common. |
| Asbestos |
Areas in our facilities where asbestos has been identified and are required
to be posted and inspected on an annual basis.
