RE: Occupational Health and Safety for Health Sciences Building LAR facility

Welcome to the University of Montana and the Department of Laboratory Animal Resources. We hope that your short visit with us will be enjoyable and productive. As even a one-time visitor to our facility, you are entitled to information concerning the physical, chemical, mechanical, radiation, and disease hazards that you may encounter in our facilities. You will also have the opportunity to participate in our occupational health and safety program. During your visit, we will appreciate having a record that you received this information when you sign in to visit or work in the facility.

Physical hazards
Caring for animals requires diligent daily cleaning of the facilities, including mopping. Slip hazards exist immediately after daily mopping in animal rooms as well as in the cage washing area, room 012 in the Health Sciences Building (HSB). The main corridor is mopped daily, Monday through Friday, between 3 and 5 p.m. Noise hazards may be encountered near large equipment such as the cage washer. Disposable hearing protection will be provided on request.

Chemical hazards
The primary chemicals that we use in large quantities are associated with the cage washer and are stored in the dirty cage washing area. There should be no reason for visitors to work with these chemicals. However, if you are splashed while visiting in these areas, an emergency eye wash station is located in the dirty cage washing area. Diluted household bleach is used for cleaning floors, and a diluted pH-balanced chlorine-containing disinfectant is used for cleaning table tops and stainless steel surfaces. Walls are cleaned with quaternary ammonium chloride. The material safety data sheets are located in the right-to-know compliance center in the main corridor just inside the facility entrance.

Isoflurane anesthesia is used in some rooms, including HSB005C (sheep surgery) and HSB016A (rodent surgery room). Doors are either marked clearly with a yellow hazard sign or allow only very limited access. Anesthetic gases are scavenged either actively through house vacuum or passively using charcoal canisters.

Mechanical hazards
The primary mechanical hazards encountered in our facility involve heavy lifting of food, bedding, or equipment. As a visitor, you will not be asked to perform these tasks.

Disease hazards
The most common hazard for persons working with or around laboratory animals is the development of allergies. If you know that you already have allergies, you are at higher risk for developing sensitivity to laboratory animals, particularly rodents. Development of allergies is generally associated with long-term exposure to animals, for months to years rather than a few days. Animals housed in this building may include sheep, rabbits, guinea pigs, hamsters, rats, naked mole rats, mice, birds, fish and frogs.

The animals housed in our facilities are screened for a variety of diseases before entry and monitored daily for signs of illness. The chance of contracting disease from them is extremely low when proper personal protective equipment, such as gloves, lab coat, and eye protection (when indicated) are used.

The HSB LAR facility intermittently houses sheep in room 006. Sheep can be carriers of a disease called Q Fever (Coxiella burnetti). Persons who are pregnant, have a compromised immune system, or have a history of valvular heart disease are at particular risk. The risk for exposure to this disease is minimized by our policy to use male or non-pregnant female sheep in our facility and to maintain a screening program in sheep for antibodies to Q fever.

Some research projects expose animals to biological agents. Rooms housing animals involved in these projects are clearly marked by door signs. Please do not attempt to handle any of these animals or their cages unless you have been trained by the principal investigator responsible for the project or his/her designee. Rodents exposed to the Lyme disease agent (Borrelia burgdorferi) are limited to HSB004, the bacterium, Staphylococcus aureus may be used in HSB004 and 006A and Clostridium difficile may be used in HSB006A.

Please feel free to ask any further questions that you may have. We hope you have safe visit at the University of Montana.
