p. 21 Part II Section 3.1 Step 4 Be Prepared for Emergencies

Add -


If the fire alarms are ringing in your building, stop what you are doing, leave all belongings and immediately proceed to the nearest, safe building exit.  Many buildings have evacuation diagrams in strategic building locations.  You can always follow the illuminated exit signs when evacuating a building unfamiliar to you.  As you leave the building, close doors behind you and use the stairs - do not take elevators.

Once outside proceed directly to your designated assembly area watching out for emergency vehicles that may be responding.  Your supervisor will inform you where your assembly area is located and your primary and secondary evacuation route.  You must remain in the assembly area until the “All Clear” has been communicated.  DO NOT re-enter your work area until given the “All Clear.”

 Section 3.9 Special Precautions for Work with Pyrophoric and Water-Reactive Materials

Special precautions are required when working with pyrophoric materials as well as certain water-reactive chemicals

  • Pyrophoric materials are solids, liquids and gases that may ignite spontaneously in air.
  • Water-reactive substances exposed to water or moisture will release a gas that is either flammable or a health hazard. The information in this section refers to water-reactive substances that have a risk of igniting on contact with moisture.


While these materials may be common reagents in chemistry laboratories, researchers should be aware that these materials have uses in many other types of research including material science and semiconductor research.

Due to the uniquely hazardous properties of these two classes of materials it is required that a hazard assessment be done and laboratory SOP must be completed if the general SOP provided in Part II 3.3 for work with Particularly Hazardous Substances of this Plan DOES NOT adequately ensure the protection of personal health and safety, and the environment for its use. The SOP should include information on storage, usage, disposal, appropriate PPE and emergency procedures for the material in the lab. See part III for a template that may be used for developing lab specific SOPs. 


Guidance on pyrophoric and water-reactive materials and a list of materials that are pyrophoric or water reactive can be found at https://ehs.mit.edu/site/laboratory-safety/pyrophoric-and-water-reactive-chemical-safety

Details on specific requirements for labs with pyrophoric materials can be found in the MIT EHS Pyrophorics SOP at https://ehs.mit.edu/site/system/files/secure/sop_004 3.pdf 

Refer to both resources before handling pyrophoric or water-reactive materials.
