Objectives

1) The objectives of this Code are as follows (see Appendix A):

OS Safety
An objective of this Code is to limit the probability that, as a result of the design or installation of the plumbing system, a person in or adjacent to the building or facility will be exposed to an unacceptable risk of injury.
OS1 Fire Safety
An objective of this Code is to limit the probability that, as a result of the design or installation of the plumbing system, a person in or adjacent to the building or facility will be exposed to an unacceptable risk of injury due to fire. The risks of injury due to fire addressed in this Code are those caused by—
OS1.1 -  fire or explosion occurring
OS1.4 -  fire safety systems failing to function as expected
OS2 Structural Safety
An objective of this Code is to limit the probability that, as a result of the design or installation of the plumbing system, a person in or adjacent to the building will be exposed to an unacceptable risk of injury due to structural failure. The risks of injury due to structural failure addressed in this Code are those caused by—
OS2.1 -  loads bearing on the building elements that exceed their load-bearing capacity
OS3 Safety in Use
An objective of this Code is to limit the probability that, as a result of the design or installation of the plumbing system, a person in or adjacent to the building or facility will be exposed to an unacceptable risk of injury due to hazards. The risks of injury due to hazards addressed in this Code are those caused by—
OS3.1 -  tripping, slipping, falling, contact, drowning or collision
OS3.2 -  contact with hot surfaces or substances
OS3.4 -  exposure to hazardous substances
OH Health
An objective of this Code is to limit the probability that, as a result of the design or installation of the plumbing system, a person will be exposed to an unacceptable risk of illness.
OH1 Indoor Conditions
An objective of this Code is to limit the probability that, as a result of the design or installation of the plumbing system, a person in the building or facility will be exposed to an unacceptable risk of illness due to indoor conditions. The risks of illness due to indoor conditions addressed in this Code are those caused by—
OH1.1 -  inadequate indoor air quality
OH2 Sanitation
An objective of this Code is to limit the probability that, as a result of the design or installation of the plumbing system, a person in the building or facility will be exposed to an unacceptable risk of illness due to unsanitary conditions. The risks of illness due to unsanitary conditions addressed in this Code are those caused by—
OH2.1 -  exposure to human or domestic waste
OH2.2 -  consumption of contaminated water
OH2.3 -  inadequate facilities for personal hygiene
OH2.4 -  contact with contaminated surfaces
OH5 Hazardous Substances Containment
An objective of this Code is to limit the probability that, as a result of the design or installation of the plumbing system, the public will be exposed to an unacceptable risk of illness due to the release of hazardous substances from the building or facility.
OP Protection of the Building or Facility from Water and Sewage Damage
OP5 Protection of the Building or Facility from Water and Sewage Damage
An objective of this Code is to limit the probability that, as a result of the design or installation of the plumbing system, the building or facility will be exposed to an unacceptable risk of damage due to the leakage of service water or sewage.
