Personal safety is a critical part of every workplace, whether it is a construction site, factory, laboratory, hospital, warehouse, workshop or chemical plant. Workers can be exposed to hazards such as falling objects, chemicals, dust, excessive noise, sharp materials, electrical energy, heat and biological agents. One of the important ways of reducing exposure to these hazards is the use of PPE, or Personal Protective Equipment.
PPE acts as a protective barrier between a worker and a workplace hazard. Common examples include safety helmets, safety glasses, gloves, safety shoes, hearing protection, respirators, protective clothing and fall protection equipment. However, PPE should not be viewed as the only method of workplace safety. Safety programs generally use PPE together with other methods of controlling hazards.
This article explains what PPE is, why PPE is important in safety, different types of PPE, how PPE is selected and how workers should use and maintain it properly.
What Is PPE?
PPE stands for Personal Protective Equipment. It refers to equipment, clothing or devices worn or used by a person to reduce exposure to hazards that could cause injury or illness.
According to the U.S. Occupational Safety and Health Administration (OSHA), workplace hazards that may require PPE can include chemical, radiological, physical, electrical and mechanical hazards. Examples of PPE include gloves, safety glasses, safety shoes, hard hats, hearing protection, respirators and protective clothing.
The type of PPE required depends on the task and the hazards present. A worker cutting metal, for example, may need eye and face protection, hearing protection and appropriate protective clothing. A worker handling certain chemicals may require chemical-resistant gloves, eye protection and suitable protective clothing.
Therefore, there is no single PPE item that can protect a worker from every workplace hazard.
Why Is PPE Important in Safety?
The primary purpose of PPE is to reduce a worker's exposure to hazards when those hazards cannot be adequately controlled through other measures.
Consider a construction worker working in an area where objects could fall from above. A properly selected safety helmet can provide protection against certain impacts. Similarly, safety glasses can help protect the eyes from flying particles, while gloves can reduce hand exposure to particular mechanical or chemical hazards.
PPE can therefore provide an important layer of protection when workers are exposed to residual hazards.
However, PPE works properly only when the equipment is appropriate for the hazard, fits the user correctly, is maintained properly and is used consistently. OSHA notes that poorly fitting PPE can reduce protection and may even create additional safety concerns.
PPE and the Hierarchy of Controls
One of the most important concepts in workplace safety is the hierarchy of controls.
The hierarchy generally places hazard controls in this order:
- Elimination
- Substitution
- Engineering controls
- Administrative controls
- Personal protective equipment
Elimination attempts to remove the hazard completely. Substitution replaces a hazardous material or process with a less hazardous alternative. Engineering controls physically isolate people from hazards, while administrative controls change how work is performed.
PPE is the final level in this hierarchy. This does not mean PPE is unimportant. Instead, it means that whenever practical, hazards should first be eliminated or controlled at their source rather than relying only on workers wearing protective equipment.
For example, if a machine has a dangerous moving component, installing an appropriate machine guard may provide protection without requiring the worker to rely solely on PPE. PPE can then provide additional protection against hazards that remain.
Different Types of PPE
PPE can be divided into different categories according to the part of the body or type of hazard it protects against.
Head Protection
Safety helmets and hard hats are designed to protect the head from certain impacts and other workplace hazards.
They are commonly used in construction, manufacturing, utilities and other environments where workers may be exposed to falling or moving objects.
The appropriate helmet must match the hazards of the workplace. Some types of head protection also provide specific levels of electrical protection, while others do not.
Eye and Face Protection
The eyes can be injured by flying particles, dust, chemical splashes, intense light and other hazards.
Common forms of eye and face protection include:
- Safety glasses
- Chemical goggles
- Face shields
- Full-face respirators
The correct choice depends on the hazard. For example, ordinary safety glasses may not provide the same protection against chemical splashes as appropriately selected chemical goggles.
Hand Protection
Hands are frequently exposed to cuts, abrasions, chemicals, heat, cold and other hazards.
Different gloves are manufactured for different applications. A glove designed for mechanical protection may not provide suitable protection against a particular chemical. Therefore, workers should not assume that any glove provides protection against every hazard.
The material, design and intended use of the glove should be considered before selection.
Foot Protection
Safety footwear helps protect the feet from workplace hazards such as falling objects, sharp materials and certain environmental conditions.
Depending on the workplace, safety footwear may incorporate features such as protective toe protection, slip-resistant soles or protection designed for particular work environments.
The footwear should be selected according to the hazards identified during the workplace assessment.
Hearing Protection
Continuous or high-level workplace noise can present a risk to hearing. Hearing protection may include earplugs and earmuffs.
NIOSH identifies hearing protection as one part of a broader approach to controlling occupational noise exposure. PPE should be selected according to the workplace noise hazard and used correctly.
Respiratory Protection
Some workplaces contain airborne hazards such as dust, fumes, gases, vapours or other contaminants.
Respirators are designed to reduce inhalation exposure when appropriate controls cannot adequately protect workers.
Respiratory protection is particularly important because simply wearing a respirator does not automatically guarantee protection. The type of respirator must be appropriate for the hazard, and workplace respiratory protection programs can include requirements related to selection, use and fit testing.
Protective Clothing
Protective clothing can reduce exposure of the skin and body to specific workplace hazards.
Examples include coveralls, chemical-resistant garments, fluid-resistant clothing and specialized protective ensembles.
The correct clothing depends on factors such as the hazard, material, design, durability and intended use. NIOSH also emphasizes that no single protective ensemble can protect against every hazard.
Fall Protection Equipment
Workers performing certain tasks at elevated locations may require personal fall protection systems.
These systems can include equipment such as harnesses and associated components designed for the particular fall hazard and work activity.
Fall protection equipment must be selected, inspected and used according to applicable requirements and manufacturer instructions.
How Is the Right PPE Selected?
Selecting PPE should begin with hazard assessment.
The employer or responsible safety professional needs to identify the hazards associated with the work activity and determine what controls are already in place. The remaining hazards can then be evaluated to determine whether PPE is necessary and what type is appropriate.
For example, consider a worker operating a grinding machine. The assessment may identify risks from flying particles, noise and mechanical hazards. Appropriate controls could include machine guarding and safe operating procedures, while PPE may provide additional protection through suitable eye, face and hearing protection.
The PPE should also fit the worker properly. An item that is uncomfortable, incorrectly sized or unsuitable for the task may not provide the intended level of protection. OSHA recommends selecting PPE that properly fits workers and maintaining it in sanitary and reliable condition.
PPE Should Match the Hazard
One of the most common mistakes in workplace safety is assuming that all PPE provides the same level of protection.
For example, different gloves have different resistance characteristics. Different respirators are designed for different types of airborne hazards. Safety glasses, goggles and face shields also provide different forms of protection.
This is why PPE selection should be based on the actual hazard rather than simply choosing the most readily available equipment.
A comprehensive PPE program should consider the workplace hazard assessment, PPE selection, proper use, inspection, replacement and worker training.
Importance of Proper PPE Fit
Proper fit is an essential part of PPE effectiveness.
A helmet that is too loose may not remain correctly positioned. Protective eyewear that does not fit properly may leave gaps around the eyes. Gloves that are too large can interfere with handling tools, while gloves that are too small may restrict movement and become uncomfortable.
Respiratory protection is another area where fit can be particularly important. Certain respirators require fit testing because the protective performance depends on achieving an appropriate seal between the respirator and the user's face.
Comfort also matters because uncomfortable equipment may discourage consistent use.
PPE Inspection and Maintenance
PPE should not simply be worn and forgotten.
Before use, workers should check equipment for visible damage, excessive wear, contamination, missing components or other conditions that could affect its performance. Damaged PPE should be removed from service according to workplace procedures and replaced or repaired when appropriate.
Cleaning and storage are also important. PPE should be maintained according to the manufacturer's instructions and workplace safety procedures.
For example, dirty protective eyewear can interfere with vision, while damaged protective equipment may no longer provide its intended protection.
PPE Training
Workers need to understand not only what PPE to wear, but also why it is required and how to use it correctly.
Training can cover the hazards present in the workplace, the limitations of the equipment, how to put it on and remove it, how to inspect it, how to clean and store it, and when it needs to be replaced.
Training is especially important when PPE is unfamiliar or when incorrect use could significantly reduce protection.
NIOSH recommends training and evaluation as important components of a PPE program.
Common Examples of PPE in Different Industries
PPE requirements vary considerably between industries.
In construction, workers may commonly use safety helmets, safety footwear, eye protection, gloves, high-visibility clothing and fall protection equipment.
In manufacturing, PPE can include safety glasses, gloves, hearing protection, protective footwear and specialized clothing depending on the machinery and processes involved.
In laboratories, workers may use laboratory coats, gloves, eye protection and other equipment selected according to the substances and procedures involved.
In healthcare, PPE can include gloves, gowns, eye protection and respiratory protection depending on the task and potential exposure.
In chemical industries, workers may require specialized gloves, eye and face protection, protective clothing and respiratory protection based on the chemicals and exposure routes involved.
These examples are general. Actual PPE requirements should always be determined from the hazards and applicable workplace requirements.
PPE Is Not a Substitute for Safe Working Practices
It is important to understand that PPE is only one part of a workplace safety system.
Suppose a workplace has excessive airborne dust. Providing workers with respirators may reduce exposure, but it does not necessarily address the source of the dust. Engineering controls such as enclosure or suitable ventilation may be more effective at reducing exposure at the source.
Similarly, hearing protection can help reduce exposure to workplace noise, but reducing noise at the source may provide broader protection.
The hierarchy of controls therefore encourages workplaces to consider elimination, substitution and engineering controls before relying on administrative measures and PPE.
What Happens If PPE Is Used Incorrectly?
Incorrect PPE use can reduce the protection that the equipment is designed to provide.
Examples include wearing safety glasses incorrectly, using the wrong type of glove, failing to replace damaged equipment, wearing a respirator without appropriate procedures, or using protective clothing that is incompatible with the hazard.
PPE can also create secondary problems if it interferes with visibility, communication, movement or other aspects of a task. For this reason, PPE selection should consider both protection and practical usability.
Workers should follow workplace safety procedures and manufacturer instructions when using protective equipment.
PPE Safety Checklist
A basic PPE safety check can include the following:
- Identify the workplace hazard.
- Determine whether the hazard can be eliminated or controlled through other methods.
- Select PPE appropriate for the specific hazard.
- Make sure the equipment fits the worker correctly.
- Inspect PPE before use.
- Use PPE according to training and manufacturer instructions.
- Keep reusable PPE clean and properly stored.
- Replace damaged or worn equipment.
- Provide appropriate training and periodic evaluation.
The exact requirements will vary according to the workplace, task, equipment and applicable regulations.
Conclusion
Personal Protective Equipment plays an important role in workplace safety by creating a protective barrier between workers and specific hazards. Safety helmets, goggles, gloves, safety footwear, hearing protection, respirators and protective clothing are examples of PPE used across different industries.
However, effective safety management goes beyond simply wearing protective equipment. Hazards should first be assessed and, where possible, eliminated or controlled through measures higher in the hierarchy of controls. PPE then provides an additional layer of protection against hazards that remain.
The right PPE must be selected for the right hazard, fit the user properly, be inspected and maintained, and be used correctly. With appropriate hazard assessment, training and consistent use, PPE can form an important part of a comprehensive workplace safety program.
