The requestor should allow at least 12-24 hours for the material to be
delivered. In the event that the material needs to be approved by the EHS
department, the requestor should allow 5-10 business days before the
material can be approved and thereafter delivered.
14.3
In the event that the material requested is a precursor/bubbler, Air Liquide
should contact the EHS to verify that the requestor and/or
tool have been
approved to use such a precursor/bubbler.
14.4
Chemicals, if delivered to an area that is not a chemical storage cabinet,
should not remain in this location for more than one work shift or 12 hours
whichever is less. Chemicals that remain in such an area for
greater than
12 hours will be returned to their storage location and the requestor will
have to go through the process again.

HANDLING
15.1
General
15.1.1
The required Personal Protective Equipment must be worn when using,
handling, transferring or transporting chemicals (See EHS-00010).
15.1.2
Ensure all containers, baths, holding tanks, storage cabinets, etc., are
properly labeled. If a chemical is transferred into smaller
container or
secondary container, the chemical identification and its associated
hazards must be clearly labeled. Labels can be obtained from label
centers located throughout the facility. Chemical
label centers are located
in: each of the clean room gowning rooms; are generally available in the
CESTM labs; and can also be obtained from the EHS office NFN-223.
15.1.3
A supply of spill clean-up materials shall be readily available in high
chemical use, transfer and storage areas (e.g. 5 gallon containers or
larger, more than 4 one gallon containers) for use in spill situations.
15.1.4
As with storage, transportation of chemicals shall be done in a manner to
prevent against accidental contact of incompatible materials.
15.1.5
All stocked chemicals should be staged to affect a First-In, First-Out
(FIFO) stock rotation process to ensure that oldest chemicals are used
first. This should avoid having chemicals
in storage that exceed the
manufacturer’s expiration dates and should also serve to minimize the
generation of hazardous waste due to raw chemicals exceeding listed
expiration dates.
