PPE plays a very important role in protecting employees from hazards in the workplace. Depending on the type of risk, the level of protection needed varies. This guide explains the different levels of PPE and when each is required to ensure workplace safety.

What Is Personal Protective Equipment? PPE Meaning

Let’s start by answering the commonly asked question: What does PPE stand for? PPE stands for personal protective equipment and refers to specialized clothing or equipment worn to protect individuals from potential hazards in the workplace or other environments. It is designed to safeguard against physical, chemical, biological, or environmental risks.

Common types of PPE include:

• Gloves
• Helmets
• Goggles
• Face shields
• Respirators
• Hearing protection
• Protective clothing

PPE is essential in industries such as:

• Healthcare
• Construction
• Manufacturing
• Laboratories

PPE means any safety gear used to prevent injuries, exposure to harmful substances, or infection. Proper use, maintenance, storage, and training in PPE are important for its effectiveness in protecting workers and reducing risks to their health and safety.

The 4 Levels of PPE: What You Need to Know

The Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH) categorize PPE into four levels. These levels help determine the type of protection workers need based on the severity of potential hazards. Understanding these levels is important when assessing workplace risks and choosing the appropriate equipment.

Level D – Minimal Protection

Level D PPE provides minimal protection against workplace hazards. It is used when there are no significant risks to the worker. This level typically includes items such as basic work uniforms, face protection, safety eyewear, or hand protection that offer basic protection against dust or minor debris.

Level D is appropriate for situations where hazards are low or nonexistent. It is not sufficient for environments with airborne contaminants, chemical exposure, or physical hazards that could lead to injury or illness.

Level C – Known Airborne Hazards, Lower Risk

Level C PPE is suitable for environments where airborne hazards are known but the risk is relatively low. This level typically involves the use of air-purifying respirators (APRs), chemical-resistant clothing, and gloves.
The equipment used in Level C protection is designed to protect against hazardous chemicals, gases, or vapors, but the risks are generally not severe. For example, this level may involve typical level C equipment, like air purifiers or disposable protective suits, to reduce exposure to harmful substances.

Level B – High Respiratory Protection, Less Skin Protection

Level B protection is used when there is a higher risk of exposure to hazardous chemicals or materials, but skin contact is limited. This level focuses on respiratory protection. Workers are equipped with a self-contained breathing apparatus (SCBA) or supplied air respirators.

Level B protection also involves wearing chemical-resistant suits to prevent skin exposure to hazardous substances. However, the level of skin protection is less extensive than in Level A. Protective equipment at this level includes things like chemical-resistant boots and gloves to prevent skin contact with toxic substances.

Level A – Maximum Protection

Level A provides the highest level of protection. It is used when workers face the highest risk of exposure to hazardous materials, airborne contaminants, or severe health threats. Workers are required to wear a fully encapsulating suit, such as a vapor protective suit, along with an SCBA or other contained breathing apparatus (CBA).

Level A equipment includes a fully protective ensemble, including hooded chemical-resistant clothing, to ensure that all exposed skin and the respiratory system are safeguarded. This level is typically required for hazardous chemical spills, biological agents, or other high-risk operations.

Types of PPE Protection

PPE is designed to protect workers from various hazards. These hazards can include physical, chemical, biological, or ergonomic risks. Each type of PPE serves a specific purpose depending on the kind of hazard present in the workplace.

Hand and Arm Protection

Hand protection, such as gloves, is important for safeguarding against chemical exposure, cuts, abrasions, burns, and electrical hazards. Waterproof chemical-resistant gloves protect workers handling hazardous substances like solvents, oils, and cleaning agents. Some gloves may be cut-resistant, providing protection for high-risk industries where workers handle sharp objects or machinery.

Cut resistant gloves are often rated by ANSI cut levels, which range from A1 to A9 to indicate how well the glove can withstand cutting forces. Mid range ratings like A4 are common choices for jobs that require a balance of dexterity and cut protection.

In higher risk environments, workers may also use cut resistant sleeves to protect their forearms from sharp edges or moving materials.

Eye Protection

Safety eyewear is important for protecting workers from flying debris, chemicals, harmful light radiation, and other potential eye hazards. Safety glasses are a common form of eye protection. Face shields provide additional coverage for situations where there is a higher risk of exposure to chemical splashes or airborne contaminants.

Head and Face Protection

Head and face protection includes hard hats or helmets, which protect workers from falling objects, electrical hazards, or impacts. Choose trusted manufacturers such as Pyramex and Lift, which offer durable hard hat options designed for demanding environments. For example, Pyramex’s Ridgeline series features a lightweight ABS shell and a full brim design, and it can be customized with company logos for added branding or identification. Face protection, such as face shields, provides additional coverage against splashes, sparks, or airborne substances. In certain situations, a combination of head and face protection is necessary.

Hearing Protection

Workers in environments with high noise levels should wear hearing protection to prevent hearing damage. Earplugs and earmuffs are common forms of hearing protection. These devices help reduce noise exposure, which is critical in industries such as construction, manufacturing, and aviation.

Body Protection

Body protection includes protective clothing, such as fall protection, high-visibility clothing like safety vests, or harnesses, to shield workers from hazardous substances or physical injury. For example, a disposable chemical-resistant overall might be required in environments with chemical spills or exposure to corrosive materials.

Respiratory Protection

Respiratory protection includes air purifying respirators (APRs), disposable respirators, and self-contained breathing apparatuses (SCBA). These devices are necessary when workers are exposed to airborne contaminants, such as dust, vapors, or gases. Respirators help ensure that workers do not inhale harmful substances. The right type of respiratory protection depends on the level of contaminants in the air and the worker's job role.

Foot Protection

Foot protection is important in workplaces where workers face the risk of injuries from falling objects, punctures, or electrical hazards. Steel-toe or chemical-resistant boots are important for preventing foot injuries. For example, outer chemical-resistant boots offer protection in environments where workers may be exposed to hazardous chemicals or fluids.

When Should PPE Be Used?

PPE should be used whenever workplace hazards cannot be eliminated through engineering controls, administrative procedures, or safe work practices. PPE is the last line of defense against potential hazards, and it should always be used as part of a comprehensive workplace safety program.

The decision to use PPE depends on a hazard assessment, which evaluates the potential risks to workers. In environments with airborne contaminants, high temperatures, or exposure to harmful substances, PPE is critical to protecting worker health.

In some industries, specific PPE may be required at all times due to the constant presence of risk. In other cases, PPE use may be based on job-specific tasks, such as when handling hazardous materials or working in confined spaces.
