Safety Engineering

safety banner 3

Safety engineering, abbreviated as SAF, also known as safety management or safety science, is a discipline that focuses on ensuring the safety of people, equipment, processes, and environments.  It involves the application of scientific and engineering principles to identify, assess, and control potential hazards and risks in various settings.  The primary goal of safety engineering is to prevent accidents, injuries, and adverse events by designing and implementing effective safety measures and controls.  It encompasses a wide range of industries and sectors, including manufacturing, construction, transportation, healthcare, energy, and more.

Confined Space Entry

  • Confined space
    • The space is large enough for you to enter and conduct work.
    • The space is not intended for continuous human occupancy.
    • Limited openings for entry and exit.
    • Examples: bins, boilers, ducts, furnaces, hoppers, manholes, pipes, pits, sewers, silos, tanks, trenches, tunnels, vaults
  • Potential hazards in confined spaces
    • Combustibles
    • Electricity
    • Mechanical hazards
    • Oxygen deficiency
    • Toxic materials
  • Immediately dangers to life or health
    • Any condition which poses an immediate threat to the health of life on an entrant
    • Would cause irreversible adverse health effort
    • Would interfere with an individual's ability to escape unaided from a permit space
  • Permit required confined space entry procedure
    • Isolate the space
    • Ventilate the space
    • Conduct tailboard
    • Complete permit
    • Test the atmosphere
    • Enter the space
  • Isolate the space from all hazards
    • Close valves
    • Enter the space
    • Lockout/Tagout equipment
    • Clean residue from the space
  • Ventilate the space
    • Use mechanical ventilation
    • Ventilate at the rate of at least four volumes per hour
    • Make sure air supply is not contaminated
  • Conduct a tailboard briefing
    • Entire crew must attend
    • Review hazards of entry and work
    • Review PPE
    • Review procedure for contacting rescue
    • Complete permit
  • Complete entry permit form
    • Permit must be correctly and completely filled out prior to entry
    • Permit must be activated by entry sipervisor's signature to be valid
    • No entry is allowed without  a valid permit
    • Permits are valid for up to 12 hours
    • When work is completed, permit and tailboard form should be returned to safety
    • Canceled permits must be kept on file for at least one year
