Title: Maintenance Safety


1
Maintenance Safety
2
Maintenance Problems
  • Operative usually works in dangerous areas from
    which others are usually excluded by various
    safety barriers
  • Emergency repairs are particularly dangerous
    because work is usually performed under stress,
    with the offending plant still hot, cold or stuck
    in some phase of its operating cycle

3
Maintenance Problems
  • No safe system developed or used
  • No means of isolation to lock-off plant and
    machinery or power supplies
  • Lack of understanding of risks by maintenance
    workers
  • Lack of training and lack of supervision

4
Maintenance Hazards
  • Confined spaces e.g. vessels, tanks, pipework,
    chambers, machines
  • Work on tanks, pipes or vessels which may contain
    a hazardous substance e.g. hot cutting or welding
    a silo containing explosive dust
  • Construction/demolition of structures and work at
    heights e.g. use of scaffolding and access
    platforms, excavations, roof maintenance, work on
    overhead cranes

5
Maintenance Hazards
  • Work on plant, machinery or equipment which is
    connected to a power source
  • Work in plant, boilers, silos etc where entry of
    free-flowing solids or liquids is a possibility
    e.g. water, grain etc.
  • Work in plant where entry of toxic or hazardous
    materials is a possibility e.g. carbon monoxide,
    methane etc.
  • Asbestos is frequently encountered in maintenance
    operations
