Overview
What this RAVS document does
Workers can be exposed to chemical and biological hazards by inhalation, skin absorption, or ingestion. A hiring client that configures this element wants to see that a contractor keeps exposure as low as reasonably practicable, assesses the hazard, controls it, and trains workers.
This document states your company's harmful substances program in the structure an ISNetworld reviewer expects: workers exposed to harmful substances, occupational exposure limits, potential worker exposure, the hierarchy of controls, worker decontamination, storage of harmful substances, education, personal protective equipment, and emergency wash equipment. It is written to Ontario regulations. The file arrives in editable Word format - add your company name, confirm the company-specific details, and upload.
What the reviewer verifies
What ISNetworld checks
ISNetworld does not just check that a harmful substances answer exists. A reviewer verifies the document addresses each requirement the hiring client has configured. For this element, that typically means confirming the document covers:
- A written harmful substances program covering chemical and biological hazards
- A requirement to keep exposure as low as reasonably practicable
- A hazard assessment to determine potential worker exposure
- The hierarchy of engineering, administrative, and PPE controls
- Worker decontamination and the safe storage of harmful substances
- Worker training on health hazards and exposure reduction

Who it is for
Who needs this RAVS
This RAVS is for contractors whose hiring clients require the chemical, biological hazards, or harmful substances element in ISNetworld, Avetta, or ComplyWorks. It applies to construction, industrial, and oil and gas companies in Ontario whose workers may be exposed to harmful substances. If a hiring client's pre-qualification configuration flags harmful substances, this is the document the reviewer is waiting on.
Practical guidance
How to pass the harmful substances review the first time
- Keep exposure as low as reasonably practicable. The document states worker exposure to a harmful substance is kept as low as reasonably practicable and does not exceed the occupational exposure limit. A reviewer expects that rule.
- Assess before exposure. The document states a hazard assessment determines the potential for exposure, and atmospheric testing results are assessed before a worker is exposed. A reviewer expects that assessment.
- Follow the hierarchy of controls. The document states engineering controls are investigated first, then administrative controls, then personal protective equipment. A reviewer expects that order.
