An embalmer preserves and prepares a deceased person’s body for viewing, burial, or transport. The work combines chemistry, anatomy, and artistry: replacing blood with preservative fluid, removing gases from internal cavities, reconstructing damaged features, and applying cosmetics so the person looks peaceful and recognizable for a final farewell. It’s a hands-on, physically demanding job that requires formal education, a supervised apprenticeship, and state licensure.
Vascular Embalming: The Core Procedure
The central task is arterial embalming, sometimes called vascular injection. The embalmer locates a major artery and its corresponding vein, typically in the neck or upper leg, and makes small incisions to access them. A tube is inserted into the artery, and preservative fluid is pumped in using either a hand-operated bulb syringe or an electric injection machine. As the fluid travels through the circulatory system, it displaces blood, which drains out through a tube placed in the vein.
The preservative fluid is mostly water mixed with formaldehyde (the primary preservative), methanol, glycerin, sodium borate, and coloring agents that help restore a natural skin tone. Some funeral homes also add propylene glycol to improve how evenly the fluid distributes through tissue. Formaldehyde works by cross-linking proteins in cells, which slows bacterial growth and prevents decomposition. Glycerin keeps tissues from drying out and becoming rigid.
A standard embalming typically takes two to four hours from start to finish, depending on the condition of the body and any complications. The result preserves the body long enough for a multi-day viewing and funeral, generally one to two weeks under normal conditions.
Cavity Treatment
After the vascular work is complete, the embalmer addresses the chest and abdominal cavities. Organs in these areas contain gases and fluids that accelerate decomposition and can cause odor or distension. Using a long, hollow needle called a trocar, the embalmer punctures the abdomen and aspirates (suctions out) the contents of the stomach, intestines, bladder, and lungs. This is one of the more invasive steps in the process. Once the cavities are emptied, a concentrated preservative solution is injected through the same instrument to treat the internal organs directly.
Restorative Art and Cosmetics
Preservation is only half the job. Families expect their loved one to look like themselves, so embalmers spend significant time on what the profession calls restorative art. Minor restoration involves correcting skin discoloration, smoothing blemishes, and setting the facial features into a natural, relaxed expression. The mouth is typically closed and secured, and small plastic caps are placed under the eyelids to maintain their shape.
More complex cases require genuine artistry. Trauma from accidents, surgical wounds, or the effects of illness like tumors can leave visible damage that needs reconstruction. Skilled embalmers use wax, plaster, and other modeling materials to rebuild facial structures, sometimes working from photographs to match the person’s appearance. Burns, autopsy incisions, and advanced decomposition all present distinct challenges.
The final stage is cosmetic application, known in the field as desairology. This covers makeup, hair styling, and nail care. The goal isn’t to make the person look “done up” but to recreate their everyday appearance. Embalmers often work closely with families to choose the right shade of foundation, style the hair in a familiar way, or apply the kind of subtle makeup the person wore in life.
Safety and Chemical Exposure
Embalming is one of the more hazardous jobs in healthcare-adjacent fields. Formaldehyde is a known carcinogen, and embalmers work with it daily. Federal workplace safety standards cap airborne formaldehyde exposure at 0.75 parts per million over an eight-hour shift, with a short-term ceiling of 2 parts per million over any 15-minute window. Funeral homes are required to use engineering controls like ventilation systems to keep fumes below these thresholds, and when that isn’t enough, respirators are mandatory.
The protective gear is extensive. Embalmers wear fluid-resistant gowns over their clothing, nitrile gloves (sometimes doubled with cut-resistant gloves underneath), goggles or full face shields, and shoe covers. Eyewash stations and emergency showers must be within reach in case of chemical splashes. Beyond chemical hazards, there’s also infection risk from bloodborne pathogens and, as highlighted during the COVID-19 pandemic, airborne diseases. In those cases, N95 respirators or powered air-purifying respirators with HEPA filters become standard.
Beyond the Preparation Room
The embalmer’s responsibilities often extend well past the embalming table, especially at smaller funeral homes where staff wear multiple hats. During training, embalmers learn to transport remains from the place of death, complete and file death certificates, obtain burial permits, coordinate with clergy and cemeteries, arrange flowers, receive visitors, and assist families in making funeral arrangements. Many also handle paperwork for Social Security benefits, veterans’ affairs, and insurance claims. The role blends technical skill with a surprising amount of administrative and interpersonal work.
Education and Licensing
Becoming a licensed embalmer requires a specific educational path. Most states require at least an associate’s degree in mortuary science from an accredited program, though some states set the bar higher. Michigan, for example, requires a three-year course that includes 60 semester hours of college coursework covering subjects like public speaking, psychology, death and dying, and multicultural studies, plus a full academic year of dedicated mortuary science instruction.
After classroom education comes a supervised apprenticeship, typically lasting one year (reduced to six months for those who already hold a bachelor’s degree). During this period, trainees must perform at least 25 embalmings and complete dozens of other tasks at least 20 times each: filing death certificates, arranging clergy, receiving visitors, applying cosmetics to the deceased, and assisting at funerals. More specialized tasks like restorative work and arranging transport of remains by common carrier must be performed at least three times. Only after finishing this apprenticeship can a candidate sit for both a national board examination and a state licensing exam.
Greener Alternatives in the Field
Traditional embalming relies heavily on formaldehyde, which raises both health and environmental concerns. The field has been slowly shifting toward lower-formaldehyde and formaldehyde-free options. Some newer embalming solutions dramatically reduce formaldehyde concentration, replacing much of it with combinations of phenol, glycerin, isopropyl alcohol, and salt. One widely cited formula brings the final formaldehyde concentration down to just 0.5 to 0.75 percent, compared to the much higher concentrations in standard fluids, while still achieving excellent preservation with minimal tissue distortion and natural color retention.
Families also increasingly choose alternatives to embalming altogether, such as refrigeration for short-term preservation, dry ice, or “green” burial practices that skip chemical preservation entirely. These options are reshaping the profession, though arterial embalming remains the standard for open-casket viewings in the United States.
