Definition of Backflow:

Water normally flows in one direction from the public water system through the customer’s cold or hot water plumbing. If the water begins to flow in the opposite direction (away from the intended user back towards the City supply), due to back pressure or back siphonage, it can become contaminated from cross connections. Backflow can occur in any commercial, industrial or residential property.

Types of Backflow – Back Siphonage

Backflow from back siphonage is caused by a negative or sub-atmospheric pressure; a drop in the water main pressure. Events that can cause back siphonage include a water main break or a high rate of water withdrawal, such as fire fighting. Back siphonage is the flowing back of used, contaminated, or polluted water from a plumbing fixture, irrigation system or vessel into a potable water supply (drinking water supply) due to a negative pressure in the supply piping.

Types of Backflow – Back Pressure

Backflow from back pressure is caused when the water system is connected to a system or supply operating at a higher pressure than the municipal water system. A booster pump or elevated piping are examples of connections that operate at a higher pressure that cause back pressure.

excerpt from Table 1

Section 63

A process involves a risk of ignition or explosion that creates a condition of imminent hazard to a person’s health or safety.

Section 65

The use of a dust collector involves a risk of ignition or explosion that creates a condition of imminent hazard to a person’s health or safety.

A Pre-Start Health and Safety Review includes a written report on the construction, addition or installation of a new or modified apparatus, structure, protective element or process.  The report details the measures necessary to bring the aforementioned into compliance with the applicable provisions of the Regulation for Industrial Establishments as listed in the table from section 7 of the R.R.O. 1990, Reg. 851.

The employer, owner, lessee or reviewer needs to consider the following points:

• The employer is responsible for ensuring that all requirements of the Occupational Health and Safety Act and regulations are complied with in the workplace. Even where a Pre-Start Health and Safety Review is not required or an exemption from the requirements of section 7 applies, the employer must ensure that workers will be protected when they use any apparatus, structure, protective element or process in the workplace.

The shaded boxes in Flow Chart 2, Existing Equipment, are to be evaluated by a person familiar with the Regulation for Industrial Establishments. Note that an evaluation is not a Pre-Start Health and Safety Review, but merely a way of determining whether a Pre-Start Health and Safety Review is required.
