Katie, Your Safety Guide
Welcome! Personal Protective Equipment (PPE) is your last line of defense against workplace hazards. While eliminating hazards is always the best approach, PPE protects you when hazards can't be completely removed. In this module, you'll learn about different types of PPE, when to use them, and how to care for them properly.

What is PPE?

Personal Protective Equipment (PPE) is specialized clothing or equipment worn by employees for protection against health and safety hazards. PPE is designed to protect specific body parts from specific hazards.

📋 OSHA Requirements
OSHA requires employers to:
  • Conduct a hazard assessment to determine PPE needs
  • Provide appropriate PPE at no cost to employees
  • Train employees on proper PPE use and care
  • Ensure PPE fits properly and is maintained
  • Enforce PPE use when required
Standard: 29 CFR 1910 Subpart I

Learning Objectives:

  • Understand when PPE is necessary and its limitations
  • Identify the six major categories of PPE
  • Select appropriate PPE for specific hazards
  • Properly wear, inspect, and maintain PPE
  • Recognize and avoid common PPE mistakes

PPE: Your Last Line of Defense

The hierarchy of hazard controls

PPE is the least effective control method because it doesn't eliminate the hazard—it only protects the individual wearing it. OSHA requires employers to use the hierarchy of controls to reduce workplace hazards.

1

Elimination (Most Effective)

Physically remove the hazard entirely. Example: Use water-based paints instead of solvent-based paints to eliminate toxic fume exposure.

2

Substitution

Replace the hazard with something less dangerous. Example: Use plastic pallets instead of wooden ones to reduce splinter injuries.

3

Engineering Controls

Isolate people from the hazard. Example: Install machine guards, local exhaust ventilation, or sound-dampening enclosures.

4

Administrative Controls

Change work procedures to reduce exposure. Example: Rotate workers, limit exposure time, implement safety procedures.

5

PPE (Least Effective)

Protect individual workers with equipment. Example: Safety glasses, gloves, respirators. Used when other controls aren't feasible or as an additional layer of protection.

⚠️ Why PPE is Last
PPE relies on proper selection, fit, use, and maintenance by each individual worker. It can fail due to damage, improper use, or poor fit. It doesn't eliminate the hazard for anyone. That's why it should only be used when better controls aren't possible or as backup protection.

Six Major Categories of PPE

Protecting your whole body

OSHA recognizes six main categories of PPE, each designed to protect specific body parts from specific hazards.

👓
Eye & Face
Protects against flying particles, chemicals, radiation, and impact.
Safety glasses, goggles, face shields, welding helmets
👷
Head
Protects against falling objects, bumps, and electrical hazards.
Hard hats (Type I & II), bump caps
🥄
Hand
Protects against cuts, chemicals, temperature extremes, and vibration.
Cut-resistant gloves, chemical gloves, heat-resistant gloves
👢
Foot & Leg
Protects against crushing, punctures, slips, chemicals, and electrical hazards.
Steel-toe boots, metatarsal guards, electrical hazard shoes
🎧
Hearing
Protects against noise-induced hearing loss in loud environments (85+ dB).
Foam earplugs, reusable earplugs, earmuffs
😷
Respiratory
Protects against airborne hazards including dust, fumes, gases, and vapors.
N95 masks, half-face respirators, full-face respirators, SCBA
💡 Selecting the Right PPE
PPE must be selected based on the specific hazards present. A hazard assessment identifies what protection is needed. Never assume one type of PPE protects against all hazards—leather gloves won't protect against chemicals, and safety glasses won't protect against chemical splashes.

Eye and Face Protection

Protecting your vision

Eye injuries are among the most common and preventable workplace injuries. Every day, 2,000 U.S. workers sustain job-related eye injuries—90% of which could be prevented with proper eye protection.

  • Safety Glasses: Basic protection against flying particles and debris. Must have side shields. ANSI Z87.1 rated. Good for general shop work, construction, and maintenance.
  • Safety Goggles: Full seal around eyes. Protects against liquids, dust, and chemical splashes. Required when working with chemicals or in dusty environments. Can fit over prescription glasses.
  • Face Shields: Protects entire face from splashes, flying particles, and heat. Must be worn WITH safety glasses or goggles (not alone). Required for grinding, chemical handling, and some power tool operations.
  • Welding Helmets: Protects eyes and face from intense light, sparks, and UV radiation. Shade number varies by welding type (Shade 10-13 for most arc welding). Auto-darkening lenses available.
⚠️ Common Eye Protection Mistakes
  • Wearing damaged or scratched eye protection (reduces visibility and protection)
  • Wearing safety glasses without side shields
  • Using face shields alone without safety glasses underneath
  • Choosing wrong lens tint for the task
  • Poor fit—gaps allow particles to enter
✓ Proper Care
Clean lenses regularly with soap and water or approved cleaner. Store in protective case when not in use. Inspect for scratches, cracks, or damage before each use. Replace immediately if damaged. Never modify or alter safety eyewear.

Head Protection

Hard hats save lives

Head injuries can be fatal or cause permanent disability. Hard hats are required in areas where there is potential for head injury from falling objects, bumps, or electrical hazards.

🔧 Hard Hat Types
Type I: Protects top of head from impact and penetration. Most common type.

Type II: Protects top AND sides of head from impact and penetration. Required for confined spaces and areas with side impact risks.

Class G (General): Low-voltage protection up to 2,200 volts. General purpose use.

Class E (Electrical): High-voltage protection up to 20,000 volts. Required for electrical work.

Class C (Conductive): No electrical protection. Lightweight, provides ventilation. NOT for electrical work.
  • When to wear: Construction sites, areas with overhead work, around heavy equipment, in confined spaces, near electrical hazards, anywhere required by your employer.
  • Proper wear: Wear with bill facing forward. Adjust suspension system for snug fit. Maintain 1-inch clearance between suspension and shell. Don't wear backwards unless designed for reverse wear.
  • Inspection: Check shell for cracks, dents, or penetration before each use. Inspect suspension system for tears, fraying, or loss of elasticity. Check for UV damage (chalky appearance, loss of color).
  • Replacement: Replace after ANY impact. Manufacturer recommends replacement every 5 years from manufacture date (check inside for date). Replace suspension yearly.
❌ Never Do This
Don't drill holes, paint, or modify hard hats—this weakens protection and voids ANSI certification. Don't wear hats, caps, or hoodies under hard hats—they prevent proper fit. Don't store in direct sunlight or extreme heat (degrades plastic). Don't use as a seat or step stool.

Hand Protection

Choose the right glove for the job

Hands are the most frequently injured body part. There is no "universal" glove—different hazards require different gloves. Using the wrong glove can be worse than no glove at all.

  • Cut-resistant gloves (ANSI A1-A9): Protect against sharp edges, blades, glass. Higher numbers = more cut resistance. Use for handling sheet metal, glass, sharp tools. Don't use around rotating machinery—gloves can get caught.
  • Chemical-resistant gloves: Material depends on chemical (nitrile, neoprene, butyl, PVC, latex). Check glove's chemical resistance chart. No glove resists all chemicals. Replace when degraded or permeated.
  • Heat-resistant gloves: Protect from hot surfaces, welding, foundry work. Rated by temperature and contact time. Leather, Kevlar, or aluminized materials. Don't use wet—conducts heat.
  • Electrical-insulating gloves: Rubber gloves rated by voltage class (Class 00-4). Must be tested regularly. Leather protectors worn over rubber gloves. Only for qualified electrical workers.
  • General work gloves: Leather, cotton, or synthetic. Protect from abrasions, splinters, blisters. Not for chemicals or high heat.
  • Disposable gloves: Nitrile, latex, vinyl. Protect from light contamination and dirt. Change frequently. Not for chemicals or mechanical hazards.
⚠️ Glove Safety Rules
Never wear gloves around rotating machinery (drill press, lathe, grinder)—they can catch and pull your hand in. Remove gloves when climbing ladders—reduces grip. Size matters—loose gloves reduce dexterity and can catch; tight gloves cause fatigue. Inspect before each use for holes, tears, or degradation.
Slide 8 of 15

Foot & Hearing Protection

Protecting feet and ears

Foot Protection 👢

  • Steel-toe boots (ASTM F2413): Protect from crushing injuries (up to 75 lbs compression). Required in construction, warehouses, manufacturing. Don't wear if toes are exposed—defeats purpose.
  • Metatarsal guards: Protect top of foot. External or built-in. Required when heavy objects might fall and roll onto foot.
  • Puncture-resistant soles: Protect against nails, screws, sharp objects. Steel or composite plates in sole. Required on construction sites.
  • Electrical hazard (EH) boots: Insulate from electrical shock. Must meet ASTM standards. Secondary protection—not for intentional contact with electricity.
  • Slip-resistant shoes: Specialized tread patterns for wet or oily surfaces. Required in kitchens, food service, some manufacturing.

Hearing Protection 🎧

Noise-induced hearing loss is permanent and cumulative. Hearing protection required at 85 dB (8-hour average) or above. That's the noise level of heavy city traffic or a kitchen blender.

  • Foam earplugs: Disposable. 29-33 dB noise reduction. Must be rolled, compressed, and inserted properly. Replace daily. Most common and convenient.
  • Reusable earplugs: Silicone or rubber. 20-30 dB reduction. Must be cleaned regularly. More comfortable for long-term wear.
  • Earmuffs: 20-30+ dB reduction. Easier to fit properly than earplugs. Good for intermittent noise exposure (easy on/off). Can be worn with hard hats.
  • Combination (plugs + muffs): 35-40+ dB reduction. Required for extremely loud environments (>105 dB). Provides maximum protection.
⚠️ Common Mistakes
Foam earplugs: Most people don't insert them properly. Roll into thin cylinder, pull ear up and back, insert deeply, hold 30 seconds while foam expands. Should not stick out of ear canal.

Respiratory Protection

Breathing safely in hazardous atmospheres

Respiratory hazards include dust, fumes, mists, gases, vapors, and oxygen-deficient atmospheres. Respirators are the most complex PPE and have strict OSHA requirements.

🚨 Critical Respirator Requirements
OSHA requires a comprehensive respiratory protection program (29 CFR 1910.134) that includes:
  • Medical evaluation before respirator use
  • Fit testing (qualitative or quantitative) annually
  • Training on proper use, limitations, and maintenance
  • Written program with SOPs
You cannot just grab a respirator and use it—training and fit testing are mandatory.
  • Filtering facepiece (N95, N99, N100): Disposable masks. Filter airborne particles. N95 = filters 95% of particles ≥0.3 microns. Used for dust, mists, non-oil aerosols. NOT for gases/vapors or oxygen-deficient areas. Must pass fit test.
  • Half-face respirator: Reusable mask covering nose and mouth. Uses replaceable cartridges/filters. Must match cartridge to hazard (organic vapor, acid gas, particulate, etc.). Requires fit testing and clean-shaven face. Good for 8-hour exposure.
  • Full-face respirator: Covers entire face including eyes. Better seal than half-face. Protects eyes from irritants. Provides higher protection factor. Used for higher concentrations or when eye protection needed. Requires fit testing.
  • Powered Air-Purifying Respirator (PAPR): Battery-powered fan pulls air through filters. Easier breathing. Works with facial hair. Hood or helmet style. More expensive but more comfortable for long use.
  • Self-Contained Breathing Apparatus (SCBA): Supplies own air from tank. Used in IDLH (Immediately Dangerous to Life or Health) atmospheres, oxygen-deficient areas, or unknown atmospheres. Firefighters and emergency responders. Requires extensive training.
⚠️ Respirator Limitations
Air-purifying respirators (N95, half-face, full-face) do NOT supply oxygen. Never use in oxygen-deficient atmospheres (<19.5% O₂). Must have proper cartridge for the specific hazard. Facial hair prevents proper seal—must be clean-shaven. Check valve function before each use.

Who Pays for PPE?

Employer and employee responsibilities

OSHA requires employers to provide most PPE at no cost to employees. Both employers and employees have specific responsibilities.

👨‍💼

Employer Must Provide (at No Cost)

Eye protection, face shields, hard hats, gloves (except for specific exceptions), safety shoes (in some cases), hearing protection, respirators and all components. Employer pays for initial PPE, replacements due to wear or damage, and upgrades when needed.

👤

Employee May Be Required to Pay For

Safety shoes (unless specific hazards require employer-provided footwear), prescription safety glasses (employer provides non-prescription), replacement PPE lost or intentionally damaged by employee. Most employers provide these anyway as a benefit.

Employee Responsibilities:

  • Wear required PPE whenever it's needed
  • Properly care for, clean, and maintain PPE
  • Inspect PPE before each use
  • Report damaged or worn PPE immediately
  • Follow all PPE policies and procedures
  • Participate in required training
  • Get fit-tested for respirators annually
⚠️ Discipline for Non-Compliance
Employers can discipline employees who refuse to wear required PPE. However, employees have the right to refuse work if they believe PPE is inadequate or unsafe. Report concerns to your supervisor or OSHA.
Slide 11 of 15

PPE Inspection & Maintenance

Keep your PPE in working condition

Inspect ALL PPE before each use. Damaged or worn PPE doesn't protect you. Replace immediately when defects are found.

1

Daily Inspection

Before starting work, visually and physically inspect each piece of PPE. Look for cracks, tears, holes, worn spots, missing parts, chemical degradation, or any damage that affects protection. Don't use damaged PPE.

2

Cleaning

Clean PPE according to manufacturer instructions. Remove dirt, contaminants, and residues. Use approved cleaners. Allow to dry completely. Never use harsh chemicals that degrade materials. Clean respirators after each use.

3

Storage

Store PPE in clean, dry location away from direct sunlight, chemicals, and extreme temperatures. Hard hats stored in hot vehicles degrade faster. Keep in protective bags or cases. Don't leave on floor or in contaminated areas.

4

Replacement Schedule

Follow manufacturer replacement schedules. Hard hats: 5 years from manufacture. Respirator cartridges: Based on exposure and use. Safety glasses: When scratched or damaged. Gloves: When degraded, permeated, or damaged. Hearing protection: Per manufacturer guidance.

❌ Never Use Damaged PPE
Remove damaged PPE from service immediately. Don't try to repair it yourself. Tag as "defective" so others don't use it. Report to supervisor for replacement. Using damaged PPE is worse than no PPE—it gives false sense of security.

Common PPE Mistakes

Learn from others' errors

These mistakes happen frequently and can result in serious injuries. Learn to avoid them!

❌ Wrong PPE for the Hazard
Using cloth gloves for chemical handling, or safety glasses instead of goggles for liquid chemicals. Always match PPE to the specific hazard. Check your employer's hazard assessment.
❌ Improper Fit
PPE that's too large or too small doesn't protect properly. Loose gloves get caught in machinery. Ill-fitting respirators don't seal. Get properly fitted PPE.
❌ Wearing Damaged PPE
Scratched safety glasses, cracked hard hats, torn gloves, or expired respirator cartridges compromise protection. Inspect before each use and replace immediately when damaged.
❌ Removing PPE Too Early
Taking off gloves before leaving contaminated area, removing respirator while still in hazardous atmosphere. Keep PPE on until completely out of hazard zone.
❌ Poor Maintenance
Not cleaning PPE, storing in contaminated areas, leaving in direct sunlight or hot vehicles. PPE degrades faster without proper care. Follow manufacturer maintenance instructions.
❌ Assuming One PPE Protects Against Everything
Leather gloves don't protect against chemicals. N95 masks don't protect against vapors. Safety glasses don't protect against liquid splashes. Know your PPE's limitations.
❌ Gloves on Rotating Equipment
Wearing gloves around drill presses, lathes, grinders, or other rotating machinery. Gloves can catch and pull hand into machine. Remove gloves for these tasks.
❌ Not Reporting Problems
Failing to report ill-fitting PPE, damaged equipment, or inadequate protection. Your safety depends on having proper PPE. Speak up if something isn't right.
