PHYSICAL HAZARDS
Physical hazards in working with research animals are often associated with the natural traits of the animal and the maintenance of these animals.
Most animals are inherently capable of biting, scratching or kicking handlers as a defensive mechanism. Larger animals can unintentionally harm handlers in several ways including stepping or falling on them. Working with nonhuman primates poses some physical hazards due to their strength and dexterity.
Maintenance of research animals often requires the use of large cages and rack systems which can cause injury by pinching or crushing personnel. Lifting heavy ancillary caging equipment and animal supplies such as feed bags can cause back injuries. Repetitive motions associated with routine tasks of maintaining animals and their environment can lead to injuries such as carpal-tunnel syndrome.
