Study Notes
Approach to Hazardous Materials
- Always approach the scene from an upwind, uphill, and/or upstream position to avoid exposure to hazardous materials.
- Maintain a safe distance while identifying and reading placards; binoculars can aid in this process.
Identifying Placards and Guides
- Match the observed placard with the appropriate placard displayed in the reference section.
- Utilize the circled guide number associated with the placard for safety protocols.
Specific Guides for Hazard Classes
- Use GUIDE 127 for identifying FLAMMABLE materials (Class 3).
- Use GUIDE 153 for CORROSIVE substances (Class 8).
- Use GUIDE 111 when encountering DANGER or DANGEROUS signs, or if materials are unknown or suspected without visible placards. Opt for the most conservative guide when multiple hazards are present.
Importance of Hazard Guides
- Guides provide crucial information regarding significant risks and hazards related to the specific materials.
- Upon obtaining specific information like ID number or proper shipping name, refer to the most accurate guide for detailed safety measures.
Explosive Compatibility
- A single asterisk (*) on orange placards indicates an explosive's compatibility group; this should be replaced with the correct compatibility group letter.
- Double asterisks (**) represent the division of the explosive and must be replaced with the appropriate division number for accurate classification.
