HRAI ODP Refrigerant Handling study guide
HRAI ODP Refrigerant Handling · Work through your exam, one topic at a time.
The HRAI Ozone Depletion Potential (ODP)/Ozone Depleting Substances (ODS) Refrigerant Handling certification is a Canadian credential offered through the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI), a non-profit national trade association founded in 1968. HRAI describes the program area as "Canada's Ozone Layer Protection Awareness," and its refrigerant course family includes the ODP/ODS Course and the Low GWP/A2L Refrigerants Course, with delivery partners listed separately. The credential is aimed at HVACR technicians, contractors, wholesalers and others who handle refrigerants and need to demonstrate awareness of ozone-depleting substances and refrigerant management responsibilities. Related HRAI navigation includes ODP Renewal Certification, a Certification Status Lookup, Replacement ODP/ODS Wallet Cards, and a Refrigerant Courses Login, which suggests the credential is renewable and verifiable. This guide is independent study material and is not affiliated with, endorsed by, or sponsored by HRAI; always confirm current requirements directly with HRAI at [email protected] or 800-267-2231. HRAI's public pages do not publish the exam length, passing score, fee, format or validity period for this certification, and the dedicated ODP certification page currently returns "File Not Found." Candidates should therefore prepare around the published course learning outcomes and assessment requirements rather than assumed logistics. Topics on this exam: ODP/ODS Refrigerant Handling.

01ODP/ODS Refrigerant Handling: Core Concepts, Traps, and a Worked Example
Ozone-depleting potential (ODP) is a relative index that compares a substance's capacity to destroy stratospheric ozone with that of CFC-11, which is assigned ODP 1.0 by convention. Because the index is relative, a value above 1.0 is possible (halons are typically far higher), and a value of zero does not mean harmless - HFCs have ODP 0 but are potent greenhouse gases. Ozone-depleting substances (ODS) are the controlled families named in the Montreal Protocol annexes: CFCs, halons, carbon tetrachloride, methyl chloroform, HCFCs, HBFCs, bromochloromethane, and methyl bromide. A candidate must be able to place a cylinder's contents into the correct family, state whether it is an ODS, and describe the handling consequences.

- Practice questionsWhich class of substances is regulated as ozone-depleting substances under the Montreal Protocol?
- FlashcardsODP definition. Ozone Depletion Potential is a relative index, scaled so CFC-11 equals 1.0, expressing the relative amount of stratospheric ozone destruction per unit mass of a substance.
- Cheat sheetODP (ozone depletion potential) is a relative number scaled so CFC-11 = 1.0; it expresses how much stratospheric ozone a unit mass of a substance can destroy relative to CFC-11.
- Key termsOzone Depletion Potential (ODP). A number comparing how strongly a substance destroys stratospheric ozone relative to CFC-11, which is set at 1.0.
- Study planDefine ozone depletion potential and explain how chlorine and bromine loading in a molecule drives ODP values.
- Common mistakesCandidates memorise that CFCs are high-ODP and HCFCs are low-ODP but skip the per-substance figures, so they collapse distinct substances into one category number.
