The embalming process poses risks due to exposure to harmful chemicals. Learn how sensor technology can enhance safety and efficiency in this practice.
The embalming process is a method to preserve a deceased body, delay decomposition, allowing for open-casket viewings, transportation, or burial. It is performed by licensed professionals, such as funeral directors or embalmers, and involves the use of chemical preservatives. This process dates back to ancient civilizations but has evolved significantly with modern technology.
Embalming involves several steps to delay decomposition and make the deceased presentable temporarily. The typical steps involved are:
Before starting the embalming process, several preparatory steps are taken:
Cleaning: The body is thoroughly washed to remove dirt and external contaminants, often using antibacterial solutions.
Relieving Rigor Mortis: Gentle massage is used to relieve rigor mortis, restoring flexibility to the limbs and muscles.
Facial Hair and Features: Grooming includes shaving facial hair if needed, and setting the mouth and eyes to create a natural expression.
Next, the embalming fluid is injected into the body through a major artery, typically in the neck or groin area. This process nvolves two key steps:
Incision: A small incision is made to expose the artery. The location depends on accessibility, visible scarring, and clothing choice for open-casket viewings.
Fluid Replacement: The embalming fluid is pumped into the body through the artery, while any remaining blood is simultaneously drained.
After arterial embalming, the body’s cavities are embalmed to preserve further and disinfect internal organs. This process involves the following:
Trocar Insertion: A trocar, a hollow needle with a sharp cutting edge, is used to relieve gas buildup by inserting it into the abdominal or chest cavity.
Organ Preservation: Once the gases are removed, organs are treated with special chemicals for preservation.
The last step in the embalming process involves preparing the body for presentation at a viewing or funeral service. This includes ensuring the body is dressed in clothes the family or funeral director chooses, and that makeup is applied according to the family’s wishes. Safety Concerns
Working with deceased bodies carries several risks for the embalmers. The most common risk they face involves their exposure to infection diseases that may linger even after death.
Other key safety concerns include:
Chemical Hazards: The most significant risk in embalming is exposure to formaldehyde, a chemical used in embalming fluid. Long-term exposure to formaldehyde, as well as methanol, phenol, and glutaraldehyde, can cause skin irritation, breathing problems, or cancer.
Ergonomic Risks: Embalming requires physical labor involving lifting and carrying heavy bodies and using hand tools for extended periods. This increases the risk of musculoskeletal injuries, including strains, sprains, and carpal tunnel syndrome.
Environmental Concerns: Improper disposal of embalming chemicals can harm the environment, including soil and water sources. Formaldehyde-containing embalming fluid must be properly disposed of in designated areas to prevent contamination.
Poor Ventilation: Working in a poorly ventilated workspace can increase exposure to hazardous chemicals and put workers at risk of health concerns. Without adequate air circulation, toxic fumes can accumulate.
To address these safety concerns, several regulations and guidelines have been developed for the embalming process:
To become a licensed embalmer, one must earn a degree in mortuary science and pass a state licensing exam. Most states require graduation from an accredited program. Additionally, candidates must typically pass the Funeral Service National Board Exam before practice.
The US CDC (Centers for Disease Control and Prevention) doesn’t have specific rules for embalming, but provides general guidelines for handling human remains, especially with communicable diseases:
Personal Protective Equipment (PPE): The CDC recommends that embalmers wear appropriate PPE to protect against exposure to infectious agents. Typical PPEs used include gloves, gowns, aprons, eye protection, and face masks.
Standard Precautions: These are safety measures to assume that all remains could be infectious, no matter the cause of death. The principle behind Standard Precautions is that blood, body fluids (except sweat), secretions, excretions, broken skin, and mucous membranes can all carry infectious agents.
Special Cases: For diseases like Creutzfeldt-Jakob Disease (CJD), which are not spread through normal contact or environmental contamination, the World Health Organization (WHO) advises using leak-proof body bags and disinfectants like bleach.
Import and Export: Specific packaging rules apply if human remains are not fully embalmed, or the deceased has an infectious disease.
The Occupational Safety and Health Administration (OSHA) oversees safety guidelines for workers in the mortuary industry. Some OSHA regulations related to embalming include:
Respiratory Protection Standard (29 CFR 1910.134): Due to potential respiratory hazards from formaldehyde vapors, a Respiratory Protection Program must be implemented.
Bloodborne Pathogens: The Bloodborne Pathogens Standard requires safety measures, such as engineering controls, work practices, and PPE, to reduce exposure to bloodborne pathogens during embalming.
Formaldehyde Standards: OSHA has a specific standard for occupational exposure to formaldehyde (29 CFR 1910.1048), requiring employers to keep formaldehyde concentrations below the Permissible Exposure Limit (PEL) of 0.75 ppm.
Formaldehyde Monitoring: OSHA’s 29 CFR 1910.1048 mandates formaldehyde monitoring in workplaces, including embalming facilities. Employers can use monitoring systems with air monitoring sensors that measure air quality levels in real time.
Creating a safe, embalming environment is essential for workers, families, and the community. Here are some tips to ensure a safe workplace:
Follow Safety Guidelines: Adhering to established safety regulations, such as OSHA’s, minimizes risks. Embalming is not a one-person job; it requires a team effort that involves compliance and following safety procedures.
Use of Appropriate PPE: The death care industry must adhere to the PPE Standard (29 CFR 1910.132), which mandates using PPE to reduce workplace hazards. This includes gloves, goggles, and aprons to protect against exposure to bloodborne pathogens and hazardous chemicals.
Implement Effective Ventilation Systems: Implementing engineering controls, including a Local Exhaust Ventilation (LEV) system, and using the right Heating, Ventilation, and Air Conditioning (HVAC) systems, can reduce exposure to formaldehyde and other chemicals in the embalmers.
Use Sensor Technology: Integrating sensor technology such as air quality sensors and temperature sensors enhances safety through continuous monitoring of environmental conditions. Sensors act as an additional layer of protection, alerting staff to potential hazards before they escalate.
Maintain Strict Hygiene Protocols: Strict hygiene standards are necessary to prevent contamination and protect everyone involved. Protocols such as washing hands before and after handling remains, properly disposing of contaminated materials, and disinfecting equipment must be followed.
Conduct Routine Training: Keeping updated with safety regulations, training staff on safe embalming practices, and regularly reviewing protocols are crucial for maintaining a safe workplace. This ensures staff have the knowledge and skills to effectively respond to emergencies and prevent hazards.
