• Hard Hat or Safety Helmet


  A rigid device that is worn to provide protection for the head and which is held in place by a suitable suspension
• Parts of a Hard Hat

  • Suspension system (headband and straps)
  • Hard outer shell
  • Chin strap

  Protects the head from sharp objects and absorbs part of the force of impact
• Chin strap


  Secures the hard hat to the wearer's head
• Brim


  Redirects the direction of the falling object
• Care and Maintenance of Hard Hats

  Wash with mild soap and water
• Occupational Eye and Face Hazards

  • Large flying particles and fragments
  • Dust, fumes, mists, and small particles
  • Vapors and liquids
  • Intense heat and radiation
• Effects of Occupational Eye and Face Hazards

  • Permanent loss of vision
  • Temporary loss of vision
  • Inflamed eyes
  • Skin Burns
  • Lacerations
  • Fractures
  • Broken Teeth
• Protective eye and face equipment shall be required where there is a reasonable probability of injury that can be prevented by such equipment
• Safety Spectacles or Glasses


  Primary protective devices intended to shield the wearer's eyes from flying and striking objects, glare and injurious radiation hazards
• Sideshield


  Integral device or an accessory attached to spectacles that provides side exposure protection to the eye
• Goggles


  Primary protective devices intended to fit the face immediately surrounding the eyes and provide a secure shield around the entire eye area
• Face Shield


  Protective device intended to shield the wearer's face, or portions thereof from striking objects or chemical, heat and glare hazards
• Hearing Protection Device


  Anything that can be worn to reduce the level of sound entering the ear
• You should wear a hearing protection device whenever you are exposed to noise that is 90 decibels or greater for an 8-hour period of time
• Arm's Length Rule


  If two people (with no hearing impairment) have to raise their voices or shout to be heard in a distance of less than an arm's length from each other, the sound level is potentially hazardous
• Types of Hearing Protectors

  • Earplugs
  • Earmuffs
• Earplugs


  Hearing protectors placed inside the ear to block out noise. To work effectively, they should fit snugly into the ear canal
• Earmuffs


  A device composed of a headband with two cushioned ear cups that form a seal around the outer ear, covering it completely and blocking out the noise
• Respiratory Hazards


  • Acids/Mists
  • Solvents/Vapors
  • Gases / Smoke
  • Dusts/Particulates
  • Heavy Metals/Fumes
• Respiratory Protection


  • Filtration respirator
  • Chemical respirator
  • Air-supplying respirator
• Filtration Respirators or Mechanical Respirators

  Screen out dust and some form of mist. Such filters need to be replaced at frequent intervals
• Chemical Cartridge Devices


  Remove contaminants by passing the tainted air through material that traps the harmful portions. There are specific cartridges for specific contaminants
• Air-Supplying Respirators


  Self-Contained Breathing Apparatus (SCBA) supplies air from an air tank strapped at the person's back or from a distant source
