OHS

Occupational Health Services. The U-M department responsible for providing Michigan Medicine and Ann Arbor campus faculty and staff with services for the prevention, treatment, and rehabilitation of occupational illnesses and injuries.

OLAW

The Office of Laboratory Animal Welfare.

Opiate

An opiate is an opioid drug such as buprenorphine, fentanyl, or morphine.

Orf

Contagious ecthyma, also known as orf or contagious pustular dermatitis, can cause crusting scabs anywhere on the body. Lesions are most frequently seen on the lips, nose, eyelids, tongue, ear, udder, and mucous membranes of sheep. In humans, the disease usually causes a firm, painful nodule on the hands or fingers. This localized lesion usually persists for 1-4 weeks.

Contagious ecthyma is transmissible to humans by direct contact with a lesion or with a contaminated fomite (e.g., bedding, equipment, manure, feed).

Ovariohysterectomy

Surgical removal of the female reproductive organs.

Oversee

Oxidizer

Any oxidizer can be an element of a surgical fire including oxygen, anesthetic gases, nitrous oxide, medical air, and ambient air.
