How to Wear PPE Before Cleaning a Death Scene
1. Gloves
Gloves act as your hands’ primary shield against biohazards, including bloodborne pathogens, bodily fluids, and hazardous chemicals. Here’s a closer look at what impacts glove performance.
Level of Protection
Glove protection largely depends on the material and design. Nitrile gloves stand out for their strong resistance to chemicals and their ability to show punctures clearly, making them a reliable choice for many tasks. For handling highly toxic substances, Norfoil gloves provide the highest level of safety. In biohazard cleanup, disposable nitrile gloves are often preferred for incidental contact, and double-gloving is a common practice to guard against sharp objects like needles or broken glass.
Material Durability
The material you choose should match the specific hazards you face. Nitrile gloves are known for their durability, offering better resistance to punctures and abrasions compared to latex, while also eliminating concerns about latex allergies. Latex gloves, on the other hand, are suitable for dealing with small amounts of corrosive chemicals but may not hold up in tougher conditions. Neoprene gloves provide excellent chemical resistance across a wide range, while PVC gloves are a good option for handling acids, bases, oils, and fats due to their abrasion resistance.
Comfort and Fit
Gloves that fit properly not only enhance protection but also maintain dexterity. Poorly fitting gloves are more prone to tearing, increasing the risk of exposure. Nitrile gloves have become a popular choice, offering both chemical resistance and a reduced risk of allergic reactions. Disposable gloves typically range up to 8 mils in thickness, while reusable gloves are made from thicker materials (5+ mils) for added durability.
Disposability or Reusability
The choice between disposable and reusable gloves depends on the task at hand. Disposable gloves – whether latex, nitrile, or vinyl – are ideal for minimizing cross-contamination and ensuring immediate hygiene. For biohazard cleaning, disposable nitrile gloves strike a great balance between protection, convenience, and affordability. Reusable gloves, made from thicker materials like rubber or neoprene, are more economical for extended use but require regular cleaning to remain sanitary. In some cases, reusable gloves offer better chemical protection than disposables. To choose the right gloves, consider your tasks, hygiene needs, and environmental goals. Always refer to a chemical compatibility chart to ensure the gloves match the chemicals you’re working with.
2. Respirators and Masks
Respirators and masks are crucial for protecting your respiratory system during biohazard cleanup. They shield you from harmful airborne particles that can cause severe health issues.
Level of Protection
N95 respirators are highly effective at filtering airborne contaminants, while surgical masks mainly protect against splashes but don’t provide adequate air filtration for serious biohazard tasks.
For more demanding environments, half-mask and full-face respirators offer advanced air filtration along with added protection from fumes, toxic chemicals, and transmittable diseases. Full-face respirators also safeguard your eyes and face from splashes and particles. In the most hazardous conditions, positive-pressure supplied air respirators or self-contained breathing apparatuses (SCBAs) provide the highest level of respiratory protection.
The COVID-19 pandemic brought increased attention to airborne pathogens, underscoring the importance of effective respiratory protection in infection control. Beyond selecting the right type of respirator, it’s equally important to consider the durability of the materials used.
Material Durability
The materials used in a respirator play a huge role in its performance and longevity. Silicone facepieces are often preferred over rubber or neoprene because they’re more comfortable, flexible, and easier to clean. Regular inspections are essential – check for cracks, tears, broken parts, or worn-out components before and after each use. Any damaged parts should be replaced immediately to ensure the respirator functions as intended.
Proper storage is just as important. Store respirators in a clean, dry place away from dust, sunlight, heat, extreme cold, moisture, and chemicals. Always follow the manufacturer’s care and maintenance guidelines for the best results.
Comfort and Fit
A respirator’s effectiveness depends on how well it fits. Filtering facepiece respirators (FFRs) are known for their comfort and low-maintenance design, but they must form a proper seal to work effectively.
"A good fit means the respirator will seal to your skin and a respirator can only work when air passes through the filter." – Enviro Safety Products
OSHA mandates an annual fit test for tight-fitting respirators to ensure they meet safety standards. For example, half-mask respirators should achieve a fit factor of at least 100, while full-face respirators require a minimum fit factor of 500. Fit tests can be qualitative, relying on the user’s sensory feedback, or quantitative, using instruments to measure air leakage. Factors like facial hair, weight changes, or dental work can impact the fit, so it’s important to choose the right size and model for your face. When evaluating comfort, think about how the mask feels on your nose, whether it accommodates eye protection, and if you can speak clearly while wearing it.
Disposability or Reusability
Whether to use disposable or reusable respirators depends on the nature of your work. Disposable N95 respirators are ideal for single-use scenarios where cross-contamination risks are high.
On the other hand, reusable respirators with replaceable filters can be more cost-effective, but they require diligent cleaning and maintenance to prevent contamination. Make sure the mask and filter are certified to work together and are approved for the specific hazards you’re dealing with. Additionally, NIOSH-approved air-purifying respirators come in both non-powered (negative-pressure) and powered (PAPRs) versions, offering varying levels of protection for different conditions.

3. Protective Suits and Coveralls
Protective suits and coveralls are essential for creating a barrier against biohazards. These full-body garments shield wearers from contaminated surfaces, liquids, and airborne particles, ensuring safety in hazardous environments.
Level of Protection
The level of protection offered by these suits depends on the specific risks involved. The U.S. Department of Homeland Security categorizes protective suits into four levels, each tailored to different contamination scenarios.
Level A suits provide the highest level of protection, shielding against vapors, gases, and particles. These suits are fully encapsulating and include a self-contained breathing apparatus (SCBA) along with chemical-resistant boots with steel toes. They’re critical for handling chemical spills and severe biological hazards where unknown contaminants pose extreme risks.
Level B suits offer the same respiratory protection as Level A but with reduced skin coverage. These chemical-resistant suits with hoods are effective against liquid splashes but do not guard against vapors.
Level C suits are the most commonly used, as they are suitable for environments where contaminants fall below OSHA’s Permissible Exposure Limits (PELs). These suits provide reliable protection against liquid splashes and are paired with half-mask or air-purifying respirators.
Level D suits are the least protective, consisting of basic coveralls, safety glasses or goggles, and steel-toed boots. They are appropriate for situations with minimal hazards and no respiratory risks.
"The level of protection assigned for a particular situation must adequately protect the wearer from the anticipated physical, chemical, and biological hazards." – U.S. Department of Homeland Security
| Level | Respiratory Protection | Skin/Face Protection | Boots | Usage |
|---|---|---|---|---|
| A | SCBA or supplied air respirator (positive pressure) | Fully encapsulating chemical-resistant suit | Chemical-resistant, steel-toed | High exposure risk, confined spaces, chemical spills |
| B | SCBA or supplied air respirator (positive pressure) | Full-body chemical-resistant suit with hood, coveralls, splash suit | Chemical-resistant, steel-toed with outer-boot cover | High respiratory risk, liquid splashes |
| C | Half-mask or air-purifying respirator | Chemical-resistant overalls, splash suit | Disposable boot covers, steel-toed | Known airborne contaminants below PELs |
| D | Optional mask (situation-dependent) | Safety glasses/goggles, splash-resistant gown/overalls | Safety boots with steel toe, optional shoe covers | Minimal hazards, no respiratory risks |
Material Durability
The durability of protective suits depends on the materials used. Impermeable materials like rubber or Tyvek are resistant to tears and punctures, which is crucial for biohazard work. For instance, the MIRA Safety HAZ-SUIT fabric combines puncture resistance with excellent barrier properties and boasts an extended shelf life. While standard hazmat suits typically last 5–10 years, materials like those in the HAZ-SUIT can last significantly longer, offering peace of mind in long-term storage.
Comfort and Fit
Protection is only effective if the suit fits well. Poorly fitting suits can restrict movement, cause fatigue, and allow contaminants to enter through gaps. To address this, protective suits often feature durable outer layers for defense, along with inner layers designed to manage moisture and provide comfort during extended use. A properly fitted suit ensures mobility and maintains a secure barrier, especially during critical donning and doffing procedures.
Disposability or Reusability
Choosing between disposable and reusable suits depends on the nature of the hazards, usage frequency, and logistical factors.
- Disposable suits are ideal for high-risk situations involving chemical exposure or biological contaminants. They eliminate the need for maintenance and reduce the risk of cross-contamination, though they generate more waste and come with recurring costs.
- Reusable suits are better for frequent use in demanding environments. They are more cost-effective over time but require thorough cleaning and inspection after each use. However, chemical permeation – when chemicals penetrate the suit material at a molecular level – can be a concern, as surface decontamination might not fully remove embedded contaminants.

4. Eye Protection: Goggles and Face Shields
Protecting your eyes during biohazard cleaning isn’t just a precaution – it’s a necessity. Contaminated fluids can easily splash into your eyes, posing a serious risk of infection. Goggles and face shields are both essential tools, but they serve different purposes and provide varying levels of protection.
Level of Protection
Goggles are your go-to for the most reliable protection against splashes, sprays, and respiratory droplets. The National Institute for Occupational Safety and Health points out that goggles with indirect vents and anti-fog coatings offer unmatched defense compared to standard safety glasses:
"Appropriately fitted, indirectly-vented goggles with a manufacturer’s anti-fog coating provide the most reliable practical eye protection from splashes, sprays, and respiratory droplets."
– National Institute for Occupational Safety and Health
Face shields, on the other hand, provide broader coverage, shielding not just your eyes but also your nose and mouth. While they can reduce inhalational exposure by up to 96% at close range, they’re not effective against smaller aerosol particles and shouldn’t be used on their own for biohazard tasks. For maximum protection, a face shield should wrap around the face, covering from the crown to the chin and extending to at least the ears. Studies show that combining a properly designed face shield with an N95 respirator significantly reduces the risk of contamination to the eyes, nose, and mouth. For example, nurses who skipped face shields during high-risk procedures faced a three-fold increase in infection risk.
Comfort and Fit
Comfort plays a huge role in whether eye protection gets used consistently. Research shows that over half of healthcare workers avoid facial PPE because it’s uncomfortable. For goggles, features like adjustable nose bridges and temples can help create a snug seal without causing discomfort during long wear. In dusty environments, gasketed goggles are especially useful for keeping particles out, and anti-fog coatings are a must in humid conditions – particularly when masks direct warm air upwards.
Face shields also have their own comfort challenges. Adjustable tension systems, proper weight distribution, and good ventilation can make them easier to wear for long periods. Additionally, a design that allows free movement of the head and neck boosts usability. Comfort and fit are key, but durability is just as important.
Material Durability
The materials used in goggles and face shields determine how well they hold up under repeated use and cleaning. Polycarbonate lenses are a standout choice – they’re impact-resistant and better at handling chemical splashes than standard plastics. However, scratches and fogging can reduce their effectiveness over time.
Anti-fog coatings applied by manufacturers tend to last longer than spray-on alternatives, but they still need careful cleaning to stay effective. Frame materials also matter; for instance, metal frames can corrode when exposed to bleach, while durable plastics are better at resisting wear and tear from frequent disinfection.
5. Foot Protection: Boots and Shoe Covers
Just like gloves, masks, and eye protection, proper footwear is an essential part of your personal protective equipment (PPE) setup. When dealing with biohazardous environments, your feet are exposed to contaminated fluids and debris, making targeted protection a must. The right footwear not only keeps your shoes clean but also shields you from infections and injuries that could take you out of commission.
Level of Protection
For high-risk biohazard tasks, chemical spill boots are your go-to option. Made from chemical-resistant materials, these boots are completely non-permeable to liquids, including hazardous substances. This makes them indispensable for tasks like crime scene cleanup or working with toxic chemicals.
In less hazardous situations, protective shoe covers can be a practical choice. These covers slip over your regular shoes, offering a layer of protection for both your footwear and yourself, provided the scenario doesn’t involve exposure to dangerous chemicals.
OSHA regulations emphasize the need for footwear that protects against spills, toxins, and electrical hazards while also featuring non-slip soles. When shopping for shoe covers, ensure they meet ANSI or OSHA standards. For example, the ANSI Z41-1983 standard addresses impact and compression protection.
Material Durability
The longevity and effectiveness of protective footwear depend heavily on the materials used. Common materials like rubber, latex, and PVC are ideal for chemical-resistant boots.
For added safety, heavy-duty boots often feature steel or composite safety toes and reinforced soles to guard against punctures, crushing, and sharp objects. Did you know that most foot injuries occur from objects falling from less than 4 feet, with a median weight of about 65 pounds? This highlights the importance of robust toe protection.
Sole materials also matter when it comes to electrical safety. Electrically conductive shoes help prevent static buildup, while electrical hazard (EH) rated shoes are designed to protect against shocks by being non-conductive. If you’re weighing your options for toe protection, composite toes are a lighter alternative to steel, though steel toes remain popular for their durability – even if they’re heavier and conduct heat more readily.
Comfort and Fit
As with any PPE, comfort and proper fit are crucial. Ill-fitting boots or shoe covers can compromise both safety and effectiveness. To ensure the best fit, try on safety footwear later in the day when your feet are slightly swollen. Measure both feet and select footwear based on the larger and wider foot.
Don’t forget to inspect your footwear regularly. Look for signs of wear and tear, as damaged shoes can undermine their protective qualities and your comfort.
Disposability or Reusability
Choosing between disposable and reusable foot protection often comes down to your specific needs and budget. Disposable shoe covers, typically made from materials like polypropylene or polyethylene, are cost-effective for short-term use. They help prevent the spread of pathogens but can tear easily and may lack grip.
Reusable neoprene boot covers, on the other hand, are a more durable option. They’re lightweight, machine washable, and often come with rippled soles for better traction. While they require a higher upfront investment, they last longer, are more economical in the long run, and are kinder to the environment.
A study from the University of Arizona found coliform and E. coli bacteria on 96% of footwear exteriors, underscoring the importance of effective foot protection. Additionally, over 170,000 workplace injuries to the foot, ankle, or toes result in lost or restricted workdays each year. Clearly, investing in proper footwear is key to staying safe and productive in biohazard environments.
| Feature | Disposable Shoe Covers | Reusable Neoprene Boot Covers |
|---|---|---|
| Material | Polypropylene, Polyethylene, SMS | Neoprene |
| Durability | Low | High |
