Chapter 3: Personal Protective Equipment (PPE)

  • Chapter Outcome: Students will be able to select and use PPE in various environments and working conditions, complying with Omani regulations and OSHA standards.
  • PPE Introduction: PPE are worn by workers to reduce potential hazards, preventing accidents, injuries, and illnesses.
  • PPE types protect against physical, electrical, mechanical, chemical, radiological, and other workplace hazards (e.g., falls, trips, slips).

3.1 Introduction

  • PPE are equipment worn to reduce the severity of exposure to potential hazards that might lead to accidents, injuries, and illnesses.
  • Purpose: PPE protect operators from physical, electrical, mechanical, chemical, radiological, and other workplace hazards like falls, trips, slips.

3.2 Safety Helmets

  • OSHA mandates head protection.
  • Employers are responsible for worker safety helmets.
  • Helmets must comply with EN397 (general industry) and 29 CFR 1926.100 (construction/demolition).
  • Helmets are color-coded for easy identification.
  • Important properties: resistance to penetration, shock absorption, heat, electrical, and flammability.

3.3 Safety Shoes

  • OSHA standards mandate safety toe footwear.
  • Employers must provide safety shoes.
  • Footwear must meet OSHA standard 29 CFR 1910.136 (e.g. leather upper, oil-resistant, non-skid soles).
  • Safety shoes protect feet, prevent slipping, and protect from penetrating or crushing hazards.

3.4 Ear Plugs

  • Two main types of hearing protection: Ear plugs (disposable polyurethane foam) and earmuffs (more rigid).
  • Earmuffs cover the outer ear with acoustic seals and absorbing materials.
  • Excessive noise can affect the nervous system, hinder cochlea function, and cause balance problems/tinnitus.

3.5 Safety Gloves

  • Safety gloves protect hands from hazardous chemicals, dangerous materials, and contamination.
  • Selection criteria: hazards, comfort, dexterity, grip, and temperature protection.
  • Different types include fabric, coated, leather, plastic, latex, Kevlar, butyl rubber, aluminized.
  • OSHA standard 1910.138 governs hand protection.

3.5.1 Specific Glove Types & Materials

  • Glove materials are categorized based on their resistance to various hazards (acids, bases, oils, fats, peroxides, amines,organic solvents, etc).

  • Nitrile, cotton, leather/welding gloves are examples.

3.6 Safety Harness

  • Safety harnesses are used for working at high altitudes to prevent falls.
  • OSHA standard 1910.140 regulates safety harnesses and fall protection.
  • Safety harnesses are categorized into four classes: Class 1 (body belts), Class 2 (seat harnesses), Class 3 (full body harnesses), and class 4 (suspension belts/boatswain’s chairs)

3.7 Safety Spectacles, Goggles, and Face Shields

  • Eye protection equipment is selected based on risk assessment and varies widely.
  • Safety spectacles protect against low-energy projectiles (metal chips, scraps).
  • Safety goggles protect against high-energy projectiles and dusts.
  • Face shields protect against high-energy projectiles and radiation.
  • OSHA standards 29 CFR 1910.132 and 1910.133 regulate eye protection.

3.7.1 Safety Spectacles Protection

  • Tempered safety glasses are smooth around the edges.
  • Marked with kitemark (e.g., BS EN14449 for laminated glass, EN12150 for toughened glass).
  • Wearing contact lenses near high-temperature sources is dangerous (melting, blindness.

3.8 Coveralls

  • Protective clothing (e.g., coveralls, aprons, coats) protects against heat, cold, radiation, chemical attacks, and abrasions.
  • Coveralls/coats are often made of PVC materials; in petroleum industries, workers use pure cotton due to static electricity.
  • Quality standards are covered by OSHA standard 1910.132.

3.9 Heat/Flame-Resistant Suits

  • Heat or flame resistant clothing (FRCs) provides protection against hydrocarbon flash fires.
  • Required in refineries and petrochemical industries.
  • Mandated by OSHA standard 29 CFR 1910.269 (protection from flames, electric arcs, voltages over 600 volts).

3.10 Self-Contained Breathing Apparatus (SCBA)

  • SCBA delivers controlled air from a cylinder to a full-face mask.
  • Used in situations with heavy dust, gas, vapour, fires, smoke, and tunnels.

Conclusion

  • Employers prioritize Health, Safety, and Environment, providing suitable PPE, safety precautions, and procedures, though employees have rights in demanding these.
  • Employers are responsible for providing appropriate PPE.
  • Employees have rights in demanding the availability of PPE, safety precautions, and safety procedures.

Laboratory Experiments

  • Assessing workplace conditions, selecting suitable PPE based on the application, and writing reports.

Class Assignments

  • Demonstrating various PPE types, handling them.
  • Showing safety videos (PPE specific to workplace/environment).
  • Writing reports about suitable PPE for different workplaces/environments.
  • Referring to OSHA standards & methods for identifying quality products.

Assignment 3

  • Listing PPE suitable for different applications (hands, body, feet, eye, hearing protection).
