GUIDANCE DOCUMENTS

Guidance documents assist code officials, inspectors, owners, operators, and permit holders with two important compliance topics:

• Hazardous Materials Reports and 
  
• A2L Refrigerant Detection Systems. 

The following documents provide practical guidance on:

• when hazardous materials documentation may be required,
• what owners need to know when asked to provide a Hazardous Materials Report, and
• why A2L refrigerant detection systems must be functionally tested and verified in the field—not simply accepted based on listing or visual inspection.  
  

[Hazardous Materials Report (TAR/HMOR) Policy]
[Owner Handout: Hazardous Materials Reports – What You Need to Know]
[AHJ Enforcement Bulletin: A2L Refrigerant Detection Systems]

These resources are intended to support consistent enforcement, clear communication, and safer buildings and premises.
