Controlling Quantities of Hazardous Chemicals in Fire Control Zones

Overview:
The EHS department monitors lab activities for type, quantities and proper storage of
hazardous materials. This is achieved through the following measures:
Chemical procurement and inventory: The Environmental Health and Safety (EHS)
Department procures hazardous chemicals for the campus. EHS completes risk
assessments for new materials or new hazard classes of materials. EHS verifies there are
sufficient controls in place to minimize risk. The EHS Department maintains an inventory of
chemicals by laboratory.
Material storage: Hazardous materials are stored in approved containers, separated by
reactive groups. Laboratories across campus are equipped with flammable storage
cabinets, cabinets for safe storage of acids and bases and cabinets for hazardous
compressed gases. Containers of chemicals are labeled with the material name. Explosion-
proof refrigerators are used for storage of temperature sensitive flammable chemicals.
Periodic walk through: The EHS department periodically conducts a walkthrough of
laboratory spaces and reviews chemical use, storage and quantity.

For facilities with B-occupancy group ratings, the quantity of hazardous materials will be
limited to those allowed in the 2012 International Building Code (IBC) tables 307.1(1) and
307.1(2). These tables are summarized in Appendix 1 Storage Quantities (Tables 1 and 2),
Appendix 2 Use for Closed Systems (Tables 3 and 4), and Appendix 3 Use for Open Systems
(Tables 5 and 6).

For hazardous materials in use, the maximum allowable quantity is dependent upon
whether the system is closed or open. Use the following definitions when assessing
whether materials are used in an open or closed system.
Closed System – The use of a solid or liquid hazardous material involving a closed vessel or
system that remains closed during normal operations where vapors emitted by the product
are not liberated outside of the vessel or system and the product is not exposed to the
atmosphere during normal operations; and all uses of compressed gases. Example of a
closed system would be product conveyed through a piping system into a closed vessel,
system or piece of equipment.
Open System – The use of a solid or liquid hazardous material involving a vessel or system
that is continuously open to the atmosphere during normal operations and where vapors
are liberated, or the product is exposed to the atmosphere during normal operations.
Example of an open system would be dispensing material into a beaker or tank.


For facilities with H-occupancy group ratings, the type and quantity of hazardous materials
will be limited to the specific requirement for the type of H-occupancy (H-1, H-2, etc.) as
defined in the IBC.
