Congratulations

Congratulations on the purchase of your new NFPA 1801:2013 compliant Bullard T4N Thermal Imager. 

The Bullard T4N combines advanced thermal imaging technology with our expertise in high heat, impact 

resistant engineered polymers to bring you the most durable thermal imager on the market. The T4N’s 

innovative, compact design and logical, easy-to-use interface presents a truly personalized thermal imaging 

tool to today’s firefighters.
The benefits of using thermal imaging technology as a firefighting tool encompass nearly every aspect of 

a firefighter’s job. Thermal imaging is not, however, a technology designed to replace current firefighting 

tactics. Rather, it is a tool that allows the firefighter to be more effective and make better decisions. Some of 

the many uses for your Bullard T4N Thermal Imager include:
• Search and rescue

• Scene assessment

• Locating the seat of the fire

• Determining the spread of the fire

• Locating hot spots

• Identifying potential flashover situations

• Determining ventilation points

• Determining entry and exit points

• Overhaul

• Hazmat

• Wildland firefighting

• Incident investigation
• Training
