The Colorado State University Hazard Communication Program gives employees a means to find information about the hazards associated
with any material in their workplace.
Material Safety Data Sheets (MSDS) are fact sheets that summarize
information about the hazards, handling procedures, emergency first aid and
required protective equipment regarding each substance. Prudent Practices in the
Laboratory: Handling and Disposal of Chemicals (NRC 1995) is a great resource
discussing recognition and control of chemical hazards. Should you have a
concern or question about any substance in your workplace, discuss the situation
with your supervisor. If the supervisor is unable to answer your questions,
contact Environmental Health Services (491-4830). Make sure you are properly
trained to safely handle the chemicals you work with, and use appropriate
safety equipment.
Exposure to toxic chemicals can cause acute or chronic health effects. Such
chemicals may be carcinogens, allergens, asphyxiants, corrosives,
hepatotoxicants, irritants, mutagens, nephrotoxicants, neurotoxicants, and
teratogens (Occupational Health and Safety in the Care and Use of Research
Animals, NRC, 1997). Exposure may occur from chemicals used for cleaning or
disinfecting the environment, fixatives, anesthetic agents or materials
introduced into animals during procedures, as well as waste, bedding and
equipment used to care for those animals. All chemicals must be appropriately
disposed of http://www.ehs.colostate.edu/WHazWaste/PDF/HazWasteManual.pdf to avoid
contaminating the environment or exposing other individuals. Information about hazardous waste disposal can be found at http://www.ehs.colostate.edu/WHazWaste/Home.aspx.
Labeling
Labeling is an important aspect of the Hazard Communication Program. All containers must have a label of the common name in English to identify the contents. Learn the risks and how to handle chemicals safely.
The National Fire Protection Association (NFPA) has developed a ranking system to identify hazards of a material.
The Hazardous Material Identification System (HMIS) labels developed by the National Paint and Coatings Association (NPCA) provides information on hazards posed by a material, personal protective equipment and route of exposure.
Another labeling system used to identify hazards is the Universal Laboratory Signages.
Cleaning agents
Cleaning agents are a common form of chemical utilized by animal handlers. All
cleaning agents must be stored in labeled and tightly capped containers at all
times. Consult the product label or the MSDS for appropriate protective
equipment when handling cleaning agents. Always wear a face shield and gloves
when handling and dispensing concentrated cleaners.
Corrosives and Flammables
Corrosive materials are the most common form of toxic substances found in a
typical laboratory and are frequently used in animal facilities. These include
strong acids, strong bases and oxidizing agents. When handling corrosive
substances ensure that skin, face and eyes are protected by clothing, laboratory
coats, aprons, eyewear and/or face shields.
Flammable materials are clearly labeled as such on the product label. All
flammable materials not in immediate use should be stored in an approved
flammable materials storage cabinet. Existing approved cabinets have doors which
positively latch. Newly acquired flammable material storage cabinets must have
doors which self-close and self-latch.
Anesthetic agents
Anesthetic agents have long been associated with health hazards. Chronic
exposure to these agents have potential adverse effects on the liver, kidney,
nervous system and reproductive system. Engineering controls, such as systems
that scavenge waste gases from the source, are the best methods to control these
hazards. For more details on waste anesthetic gases go to

Spills
All chemical spills should be handled as described in Hazwaste Accident Procedures (http://www.ehs.colostate.edu/WHazWaste/Home.aspx). Familiarize yourself with these procedures and who the emergency contacts are. More importantly learn how to prevent spills and
be alert in your work area at all times. Check containers frequently for leaks.
If a spill does occur respond quickly and effectively. Small spills may be
managed by laboratory staff. Dispose of the materials used for containing the
spill as described in the
Colorado State University Hazardous Chemical Waste
Systems Manual. In the event of a large spill, remain calm and
after ascertaining that there is no immediate danger call 911 or 491-6745 and
provide the information requested by the dispatcher; protect co-workers, secure
the area and do not spread the contamination.
