Which statement about the Occupational Health and Safety Program is false? Typical services include rabies immunizations, TB testing, and tetanus immunizations. Each institution must have an Occupational Health and Safety Program for personnel who have significant contact with laboratory animals. You should enroll in the local Occupational Health and Safety Program before you begin your work with laboratory animals.

You may not decline medical treatments provided as part of the Occupational Health and Safety Program.

Which of the following statements about using a statistical analysis to justify animal numbers is true? A statistical analysis must be performed for every experimental protocol. A statistical analysis is not appropriate because the IACUC cannot properly evaluate the results. A statistical analysis is rarely useful for justifying group sizes because it gives only estimates. A statistical analysis should be used whenever possible.

a statistical analysis must be performed for every experimental protocol

cost savings

Which of the following statements is FALSE concerning the use of ether in the animal facility? Ether is a compound that remains very stable over time. Carcasses of animals euthanized by exposure to ether should be placed in an explosion-proof refrigerator or freezer. Use of ether is prohibited unless the IACUC and/or Biosafety Committee approves it based upon compelling scientific reasons. The sparks given off by non-explosion-proof refrigerators and freezers can ignite the ether and cause an explosion.
