Study Notes

Personal Protective Equipment (PPE)

  • OSHA (Occupational Safety and Health Administration) aims to ensure safe and healthful working conditions for all workers.
  • OSHA 3151-02R 2023 document guides employers and employees on PPE
  • This guidance is not a standard or regulation, only recommendations.
  • Employers are responsible for conducting a hazard assessment to identify workplace hazards.
  • They are also responsible for providing appropriate and sufficient PPE for employees.
  • Training employees on the proper use and care of PPE is crucial.
  • The document does not cover respirators or respiratory protection, this is detailed in 29 CFR 1910.134.
  • OSHA's standards and regulations apply for compliance.
  • Various standards, different by industry, exist for PPE.
  • Different types of PPE exist based on the hazard associated.
  • Employees must follow the employer's instructions regarding PPE selection and use.
  • OSHA standards are published in the Code of Federal Regulations (CFR).
  • Material included is in the public domain.

Hazard Assessment

  • A crucial first step to protect employees is a hazard assessment.
  • This process is used to identify physical and health-related hazards.
  • Examples of physical hazards: flying objects, extreme temperature changes, electrical connections.
  • Examples of health hazards: harmful chemicals, excessive radiation, exposure to infectious material.
  • The assessment should involve a facility walkthrough to identify potential hazards.

Types of PPE

  • Head protection is vital for preventing head injuries from impacts, falls, electrical shocks.
  • Eye and face protection is necessary against flying objects, chemicals, and extreme temperatures.
  • Foot and leg protection is needed against impact, heavy objects, hot surfaces, and puncture wounds.
  • Hand and arm protection is important given risks of cuts, burns, and abrasions, among others.
  • Body protection safeguards against multiple hazards (extreme temperatures, hazardous chemicals, and impacts from materials, among others).
  • PPE must also be properly maintained and replaced as needed.

Selecting PPE

  • Appropriately sized PPE is essential.
  • Comfort and suitability for the task must also be considered.
  • Gloves are an example of PPE, and appropriate selection depends on the specific hazards involved.
  • For chemical exposure, appropriate selection depends on the chemical exposure.
  • Safety and comfort must be prioritized when selecting PPE.

Training of employees on PPE

  • Employees must be trained on the correct use of PPE.
  • They need to know when PPE is needed, the specific PPE for the job, how to properly don, remove & adjust PPE.
  • Any employee who doesn't demonstrate understanding of the PPE training needs retraining.
  • Employer should evaluate PPE usage, taking into account changes in the workplace or type of PPE.
