The interactive request form allows you to select MSDS pages to download for viewing and printing, providing you with the most current information available.
You will need:
- The catalog numbers of your Hach products. Catalog numbers may be identified in any of the following ways. NOTE: the catalog numbers should be entered on the MSDS Download Page without hyphens or spaces.
- Hach product labels – all Hach product labels have the catalog number printed on them. This number can usually be found directly under the product title on the label.
- Hach's Products for Analysis catalog.
- Hach MSDS sheets printed after January 1, 2000. Please note that MSDS sheets printed before this date do NOT have the full Hach catalog number printed on them. Please contact a Customer Service Representative if this is your only source of catalog number information.
- Netscape Navigator 4.0 or above, or Internet Explorer 4.0 or above.
- Adobe Acrobat Reader 4.0 or above. Pages are formatted as Adobe Acrobat 3.0 PDF files. You may download them without using Acrobat Reader, but you will need Reader to view or print the files.
When your selection list is complete, the MSDS server will generate a single PDF file containing the forms you have selected. File download size is limited to about 60 MSDS forms. If you need more than 60 forms, you may create separate files.
How to Read an MSDS
Note: This article first appeared on our educators' subsite, H2O University. We hope many of our main site visitors will also find it useful.
What is a Material Safety Data Sheet?
The United States Occupational Safety and Health Administration (OSHA) requires all manufacturers to issue Material Safety Data Sheets (also known as MSDS's) with the first shipment of any hazardous chemical product. Hach Company issues MSDS's for all chemical shipments, from toxic mercuric acid to substances as benign as sodium chloride (salt). The purpose of the MSDS is to relay important information about the nature of the chemical -- such as its flammability, toxicity, the need for protective equipment, and spill or clean-up requirements -- to ensure the safety of any potential user of that chemical.
At first glance, the MSDS can seem like an intimidating piece of information. But the information is not that difficult to understand when broken into its component parts. And it is a very important document to read and follow.
When you receive a reagent shipment from Hach, we recommend that you:
- Read the MSDS carefully
- Discuss the cautions specified on the MSDS with your students
(note: in the plant, you might want to consider an informational program for any non-technical personnel who have access to or may come into contact with chemistries)
- Utilize necessary protective equipment
- Dispose of the reagent properly (see the MSDS for disposal information)
- Keep file copies of MSDS's in a central location accessible to all.
What to look for in an MSDS (Q&A)

- PCT Percent by weight of this component
- CAS Number Chemical Abstract Services or CAS registry number
- SARA Superfund and Reauthorization Act -- better known as the "Community Right to Know Law." If an MSDS indicates that a component is listed in SARA 313 and more than the specified amount is used, it must be reported to the USEPA every year.
- TLV Threshold Limit Value (TLV) is the maximum airborne concentration allowable for an 8-hour exposure, as recommended by the American Conference of Governmental Industrial Hygienists (ACGIH).
- PEL Permissible Exposure Limit (PEL) is the maximum airborne concentration allowable for an 8-hour exposure, as regulated by the Occupational Safety and Health Administration (OSHA).
- HAZARD Any physical or health hazards posed by this chemical are explained here.
- What are the hazards of using this product?
The hazards identification summary starts out with an emergency overview, plus ratings of the product from the Hazardous Materials Information System and the National Fire Protection Association (NFPA). This section also outlines the potential harmful effects of this product.

- What happens if it spills?
The accidental release measures section spells out the personnel who are qualified to respond to an emergency involving hazardous substances and outlines containment techniques, clean-up techniques, and any necessary evacuation procedures.
- What are the handling and storage requirements?
The handling/storage section provides general guidelines for safe handling of the product and lists all storage requirements.
- What protective measures do I need to take in the work environment?
The exposure controls/protective equipment section outlines safe laboratory practice (e.g. eyewash station nearby) and any necessary protective gear, such as eye, skin, and inhalation protection.
- What does it look/act like?
The physical/chemical properties section spells out information such as the physical state, color, odor, solubility, boiling point, melting point, specific gravity, pH, vapor density, evaporation rate, corrosivity, stability, and storage precautions.
