Organizing Your Material Safety Data Sheet Library
Safety Data Sheets (MSDSs) are produced by chemical manufacturers and must be provided by
the company that sells the material. The MSDS is updated each time the material changes.
Each manufacturer has its own MSDS for its products.
The Hazard Communication Standard (HCS) requires the practice leadership to maintain an
MSDS on file for each hazardous substance on their hazard materials list. Click here for more information on the hazard material inventory.
The MSDSs must be in English (they can be bilingual if necessary) and readily accessible
to workers in every work area. Staff members must know how to find and use them. The
preferred place to keep your MSDS library is in the employee break area or in a central
location in the hospital. OSHA discourages businesses from keeping the MSDS library in the
"boss's office;" some staff members may be intimidated by the location, and not
The MSDSs should be filed in a systematic way. It is best to file them alphabetically by
the product name instead of by operational area or category - use a three-ring binder (or
two) with tabbed alphabetical dividers. This presents less confusion to the staff member;
e. g., is bleach filed under disinfectants or under housekeeping supplies? In those
instances where a product is known by several names, you can place a piece of paper in the
alphabetical file that directs the reader to the look under the specified name given by
the manufacturer (e.g., Lasix® - see furosemide) Make sure to cover the filing system and
understanding of MSDSs during staff training sessions. The real test of the training's
effectiveness is to ask any staff member (try the newest one) to retrieve a specific MSDS
The MSDS must be for the exact product and must be from the manufacturer of the current
supply. Some practices will buy several different brands of a product (e.g., alcohol),
depending on availability or price. In these instances, it is best to keep several MSDSs -
one for each brand - in the library, so that whichever brand is purchased, the appropriate
information will be available.
When an MSDS is needed, first call the distributor who supplied the product. If the
distributor or supplier can't get it for you in a reasonable time, request them from the
manufacturer. Often the manufacturer will give a phone number directly on the label. When
all else fails, send a letter to the manufacturer at the address on the label (most often,
name, city, state and zip code will get the letter delivered or use directory assistance
to find the information.) When you request MSDSs in writing, it's not necessary to send
the first request by registered mail; if you get no response, try once more by
"return receipt requested." Keep copies of the letter and of the post office
receipt. This will demonstrate good faith efforts to obtain the MSDSs.
If you have an MSDS for a product that has not changed, but the company name has changed,
simply make a note on the MSDS reflecting the changed company name; there is no need to
get new MSDSs each time drug companies merge!
There have been several efforts by the distributors and individual companies to produce
comprehensive MSDS directories. Although these directories may be used for information
purposes, they are not replacements for your customized MSDS library. It is acceptable to
photocopy or "extract" a specific MSDS for a product and place it in your MSDS
library. Dont fall into a false sense of security by placing the large directory
books on the shelf and assuming that all your products are in there and staff members can
Computer Databases & the Internet
It is acceptable to use an on-line source for
obtaining the MSDSs, but you can't rely exclusively on the internet or an
on-line service as the library that you expect employees to use for a couple of
- 1) No MSDS database has exactly every product you need from each and every
manufacturer that you use. There are some products in the clinic that are not
obtained from the traditional veterinary vendor so it’s unlikely they will be
in one of the veterinary-specific MSDS databases, so just having access to the
database of thousands of MSDSs is useless if it doesn't have the one for the
product in question.
You certainly don't want to have some MSDSs on a computer database and some
others on paper. This will only confuse most staff members and make it more
unlikely they will find the one they need.
- 2) Although reliability has gotten much better over the years, there's
still an issue with the belief that your electronic connection to the internet
is not something within your control. And there's the issue of each and every
staff member being technically and competently able to get on the service and
do a proper search in a database of thousands of MSDSs.
The bottom line is that you can't rely on something over which you really
don't have control.
However, that doesn’t mean the computer can’t be used to solve the
MSDS library challenge! When executed properly, we do believe an IN-HOUSE
electronic MSDS library is perfectly acceptable and in many ways, better
than the printed pages in the binders.
Many modern hospitals use an "intranet" to communicate with employees, post
information and make their policy manuals readily available. In these practices,
since all staff communication is via in-house electronic memos and e-mails, the
staff has a level of competency with the system that will allow the indexing of
the MSDS library so that everyone can find exactly what they need.
MSDSs can be scanned as PDF files and are then organized on a specific page
of the in-house intranet. Now, a staff member has a full list of all the product
MSDS in the practice without the clutter of thousands of products not used by
The practice can't rely on external sources as the complete MSDS library
when there is no control over the content of those sources or very limited
control over access to them; however, an in-house computer source may be just
the answer for technologically advances practice.
