Working With Formaldehyde

Formaldehyde is a chemical used in embalming and tissue preservation, as well as in cold sterilization. Acute exposure to formaldehyde may result in pulmonary edema (fluid in the lungs), central nervous system (CNS) depression, or pneumonitis (inflammation of the lung tissue). Chronic exposure may cause irritation of the skin, mucous membranes or respiratory tract. Repeated exposure to formaldehyde may result in an allergic response. It is also a potential carcinogen. Primary exposure routes are inhalation and skin absorption.

Working with Radioactive Iodine

When patients are treated with radioactive iodine, their blood and body fluids such as urine and vomit can contain the radioactive drug. Caregivers should understand the risks of exposure. There are two different types of radiation risks: Thyroid exposure: Having the radioactive iodine absorbed by your thyroid gland. External beam radiation: Getting radiation exposure from the contaminated body fluids, just like you would from an X-ray. Preventing thyroid exposure

Varicella (Chicken Pox)

​Chickenpox is normally a fairly mild childhood illness caused by the varicella virus. Humans are the only source of infection for this highly contagious virus. Humans are infected by person to person transmission when virus comes in contact with upper respiratory tract or eyes and by contact with lesion drainage from someone with chickenpox.


Rubella (German Measles) is a highly contagious viral illness with symptoms very similar to rubeola (red measles, commonly referred to simply as "measles") but differs in the severity of symptoms and length of illness. The most serious threat of rubella is to the pregnant female who has never had rubella. If exposed to rubella, she can contract the disease which can cause serious problems for the unborn baby.
