How to Use the Orange Guides, page 151SUGGESTED OPERATIONS SHOULD ONLY BE PERFORMED BY ADEQUATELY TRAINED AND EQUIPPED PERSONNEL • PUBLIC SAFETY This section is divided into three subsections: › General Information: describes initial precautionary measures to be taken › by those first on the scene. › PROTECTIVE CLOTHING: provides general guidance on personal › protective equipment requirements including respiratory protection. The protective clothing information is general and correct selection is situation dependent, after considering the physical and chemical properties of the material, weather conditions, spill versus fire, topography, etc. › EVACUATION: suggests protective distances for immediate precautionary › measures defined for small and large spills, including suggested guidance for conditions where fire is present or likely (potential fragmentation hazard). − The term “isolate” indicates a zone of no entry that applies to the public − and first responders who are not equipped, trained, and prepared to mitigate the incident. − The term “evacuate” aims to protect as many people as possible by − removing persons from inside a zone safely. If removal is too risky, sheltering-in-place can also be considered in this zone. Materials highlighted in green in the yellow and blue sections direct the reader to consult Table 1, detailing specific response distances for toxic inhalation hazard materials and water-reactive materials (green section). EMERGENCY RESPONSE • This section is divided into three subsections: › FIRE: provides extinguishing procedures for Small Fire, Large Fire, and/ › or Fire Involving Tanks or Car/Trailer Loads › SPILL OR LEAK: includes general recommendations, and may describe › the response procedure for Small Spill and Large Spill › FIRST AID: provides specific first aid guidance to use for a product or a › guide in addition to the general first aid guidance for hazardous materials/ dangerous goods incidents. General first aid guidance is found in the “General First Aid” section situated immediately after the “How to use the Orange Guides” section. If a Canadian flag appears in this section, and the incident is located in Canada, an Emergency Response Assistance Plan (ERAP) may be required for this product. • ERG 2024 Page 149#
